2.14. Internal Department Email Lists

3. Math Accounts

3.1. Department of Mathematics Network Accounts

Who needs a network account?

To use many of our services, you must have a network account. Among other things, this gives you:

Since our servers run Linux, network accounts are sometimes called "Linux accounts"; they are also called "system accounts" or "e-mail accounts".

Usage of e-mail and network accounts is subject to the general university-wide computing policies.

Who can get an account?

All incoming faculty, staff,  postdocs and grad students automatically get a Math account when they join the department.

We also offer accounts to undergraduate math majors engaged in research with math faculty. Other affiliates may also receive accounts by special request. Accounts are created to host websites for departmental groups or projects.

How do I get an account?

Simply contact the support staff with the request. Please include the following information about the person who will receive the account:

  • First name and last name
  • Affiliation to the department
  • Existing e-mail address (preferably your email.arizona.edu address, if you have one)
  • Optional: suggested account name (to avoid name conflicts, we may end up assigning a different name)

Once the account is created, we will use the existing e-mail address to inform the user of their new account name, and ask them to follow these instructions to get started using the new account.

If I leave the department, when will my account be removed?

Please see our account removal page for more information


3.2. New Account Information

This page gives information on Math network account  setup.  If you run into difficulty, please ask us for help.


Your network account: stores e-mail, lets you publish a personal website, and gives you access to our scientific software.

3.3. Network Account Management


3.4. Passwords

Mathematics Network Account Password Change Procedure:

  1. Click on the following link: change your password
  2. Enter your username and your current password.
  3. Enter your new password twice.
  4. Click Save and you will get a response confirming that the password has been changed.  

Note: It may take up to 30 minutes for this change to affect your Math GMail password.

 

Password Rules:

  1. A password must be at least 10 characters in length.
  2. A password must consist of any 2 of the following: uppercase letters, lowercase letters, numbers, or punctuation.
  3. Passwords cannot be dictionary words or dictionary words spelled backwards.
  4. Passwords cannot be dictionary words with an added digit.
  5. Passwords cannot be repeated sequence of a few letters eg: aaabb.

Tips for creating a good password

  1. Mix up the password with letters and numbers and symbols e.g: (!@#$%^&*-=[]{};',./<>)_+.
  2. Change your password regularly and use different passwords for your math account and netid.
  3. If you a going to keep a written reminder of your password, keep it locked or in a wallet.
  4. Never use a password that is simple. E.G.: "password123", "Dragon1", "iloveyou"
  5. Never use a password that would be easy for someone who knows you to guess. E.G.: birthday, maiden name, last name, place of birth
  6. Never use your username as part of your password


3.5. Account Quotas

Account Quotas

Every Department of Mathematics network account has a disk quota which limits the amount of file system space you can use. The default quota for new accounts is 1 gigabyte (GB). If you find that 1 GB isn't enough, please contact the computer staff to request a quota increase.


If you fill up your disk quota, you may not be able to log in at all. 

Checking Your Disk Quota

To check your quota, do the following

  1. Open a terminal window. (If you are doing this remotely, then connect to your network account using SSH.)
  2. Issue the command quota. This will tell you:
    • The filesystem you are using;
    • The number of 1 KB blocks you are using;
    • The quota of how many 1 KB blocks you are allowed to use;
    • The absolute limit (you can temporarily exceed your quota in some cases, but you can never exceed this limit);
    • The number of files you are using.
  3. If your account runs out of space, you might even be unable to log in graphically. (But you should still be able to connect remotely via SSH, allowing you to delete some files.)
  4. Disk space is often used by your browser's cache. Inside your browser's Preferences, try reducing the cache size, or clearing the cache.
  5. The command du -h --max-depth=1 might help you determine where your big files are, just make sure you run it from your home directory.
  6. If you are involved in a Math Department activity that requires you to have more space, then please contact the computer staff to request a quota increase.


3.6. Network Account and Math Email Removal

 Math Department Policy on Account Termination

  • When your affiliation with our department ends we provide a grace period before account deletion so that you can move your e-mail and account files. The standard grace periods are:
    • Graduate Students: Your account will be terminated at the end of the semester following your graduation
    • Faculty: Your account will be terminated one year following your separation from the department.
    • Staff: Your account will be terminated immediately following your separation from the department.

Congratulations, you have added the PaperCut printer(s)!


Troubleshooting:


If it appears that the job was sent to the printer, but no jobs print out when you log in at the printer you should check this setting:


After you choose print, look at the advanced tab in the print options window.  Make sure user authentication is not set up.  The new system does not require it.


4.6. Using the Card Reader on the Konica Minolta Printer/Copiers

You can use your CatCard to access the Konica Minolta Printers in ENR2 third floor and Math 401.  However, it must first be associated with your Math account (account information you use to login to gmail.math.arizona.edu). 


1.  Swipe your CatCard in the card reader.  (You may have to do this twice if the printer is asleep).  

You will see this message.  Touch Yes.

2. Next you will enter your Math username and password using the keyboard or the keyboard on the touchscreen.


3.  Click Set


4.  You will have to scan your CatCard one more time to release your print job. 


This was a one time set up.  From now on you will only need to swipe your CatCard to release print jobs, make copies, etc.


4.7. Checking your print quota on the Konica Minolta Printer/Copiers

You can check how many print jobs you have left in your quota.

  1. While on the Math network, go to papercut.math.arizona.edu:9191
  2. Log in with your Math username and password.
  3. You will see information about your print jobs.

4.8. Printing from the M401-B Public Windows Computer

If you want to print from the public Windows computer in Math 401, you need to log in to the PaperCut server using your Math username and Math password.  After you choose to print something, you should see a window that looks like this:


Log in with your MATH username and password.



PaperCut will log you out automatically after 5 minutes. If you wish to log out sooner:


RIGHT-CLICK on the PaperCut icon on the lower right  and choose "Logout."







4.9. Cancel your print job submitted to the Konica Minolta Printer/Copiers

You can cancel your print jobs by logging into the papercut server, follow these steps before swiping your catcard or logging into the printer.  

  1. While on the Math network, go to papercut.math.arizona.edu:9191
  2. Log in with your Math username and password.
  3. Select Jobs Pending Release, Select Cancel below Action column.



4.10. Printing from the public iMac (Kingham) in Math 401 N

After you choose to print a document, you should see this:

Click Print.


Next you should get a Login message from Papercut.  Log in with your MATH username and password.


This leaves you logged in to the printer for 5 minutes.  If you would like to log out sooner, control-click on the  PaperCut icon at the top right of the screen and log out.




4.11. Scanning to Google Drive from KM-ENR2 and KM-401

We have upgraded our PaperCut Software and you can now send your scan jobs to your Math Department Google Drive Folder.


Log in to the copier by swiping your CatCard or using the keyboard.  Choose Scan.


Choose Scan to Google Drive.


Change the settings if you don't like the defaults, otherwise click Start



The machine will scan the documents.  If you have pages to add, click New Scan Document.  Otherwise click Send to upload the file to Drive.


 Be sure to logout when you are finished


NOTE:  The first time you scan, you will receive an email from PaperCut asking you to login to Google Drive for authorization.  When you click on the link, you will get to a screen like this:



Click Allow.  Papercut will create a folder inside your Google Drive called "Scans for Papercut MF"


5. Google Apps

5.1. Google Apps for Education - Math

In 2015, Mathematics began using Google Apps for Education (Gmail, Calendar, Sheets, Docs, Groups, Sites, etc). Here are some helpful hints: 

New to Google Apps?  Also check out Google's App Learning Center for step by step instructions!

 Gmail

Sites

 

Groups

Groups are useful as mailing lists.  

Information on the pre-set Department mailing lists is here

Google Drive


5.2. Creating webpages with Google Sites

Using Google Sites to make a Faculty homepage


One of the benefits of our adoption of Google Apps for Education is the ability to create simple webpages through Google Sites.  These pages will not be stored on the Math server, but rather in the Google cloud.   You do not need to web or HTML knowledge to create a site. These instructions will walk you through creating a Faculty homepage using a template and Classic Google Sites. Of course you are free to create other kinds of websites using Google Sites. 


 You can find more instructions here:  




Go to sites.google. com and login with your Math email address and your Math password. Please click on Back to Classic Sites if you see that in the lower left corner.

  You will see this:



Click on the red Create button.  On the next page under Select a Template to Use, click on “Browse the gallery for more” Choose Faculty Info Page.

Name your site (most likely you will want to name it with your first and last name).  You do not need to change the location settings.

Click the red Create button at the top again.

You will see the template featuring Dr. Wilbur A. Math.  To edit the page, click on the pencil icon in the upper right:


Now you can type over Wilbur’s name and contact information with your own info.

 

To change Wilbur’s photo to your own, you must first delete him.  While in edit mode, click on Wilbur’s photo.  You will see a little toolbar pop up.  Click on the Remove to remove the link, then click on the X to remove his photo.


Click on Insert Menu and choose image.


  Click on the Upload Images button to upload a photo from your computer 



After you have selected and uploaded your photo from your computer, you will see it in the Add an Image box.  Click on it and select OK.  If the photo appears too big you can adjust the size with the S, M, L buttons on the little toolbar under the newly inserted photo.

Be sure to periodically click on the blue Save Button on the upper right.  

Now you can navigate to the other pages of the site, such as Publications and click on the Pencil tool and edit the text there.  You can also use the Add Files button at the bottom of the page to upload PDFs.

 

If you want to delete a page, go to the page in question, click on the gear icon and choose Delete Page


When you have finished editing, click on the Blue Share button. 

 

Click on Change...

Then choose On - Public on the web.


This allows viewing access for everyone. Click save.

Note that in addition to being available at the rather long URL of https://sites.google.com/a/math.arizona.edu/YOURSITENAME/    Users can alternatively type in websites.math.arizona.edu/YOURSITENAME   (Where YOURSITENAME is the name of your site. )

Finally, if you would like the Homepage link on the Math website directory to point to your Google Site (as seen below),  please contact us.

5.3. Transfer Files or Email to another Google Account

Go to:

https://myaccount.google.com  and sign in with your Math GSuite credentials


On the left click on Data & Personalization


Click Start Transfer under Transfer Your Content


The steps will take you through transferring all files in your Google Drive and/or your Gmail messages.   This will copy and transfer -- the original files will stay in your Math GSuite account.


More information is available here:  https://support.google.com/accounts/answer/6386856?visit_id=636807545617692260-3194481195


6. Webpages

6.1. Personal Webpages

NOTE: We are moving away from publishing webpages on our local server as described below.  Instead, please check out the possibilities of Google Sites through our Google Apps for Education Account here

 

 

You can publish webpages  on the public internet on our math server.  Only static web pages are supported (i.e. no php, or other scripting is allowed.)

Basic facts:

 

1. Create your html page:

There are many different ways to create an html page, including writing out the code in a text editor. For beginners we recommend a Graphical User Interface (GUI) tool such as Nvu. Your main/home page should be titled index.html.

  • Nvu- Free Web Authoring Software -If you have a department-owned computer this should already be installed. There are numerous tutorials you can access from the link above.

2. Move your html page to the server:

  • The html file you have created is on your local computer. You now need to move it to your web folder on our server.
  • If you use Windows you can do this with WinSCP [download]. For Mac you can use Fugu[download]. Department computers usually have these installed by default.
  • Move your files to the pub_http_internet folder in your network account.

3. Check your page:

4. Adjust permissions if necessary:

Using WinSCP:

  • Right click on your pub_http_internet folder and choose properties. Make sure the number listed as Octal is 0711.
  • Right click on your individual html files within the pub_http_internet folder and choose properties. Make sure the number listed as Octal is 0644.

Using Fugu:

  • Right click on your pub_http_internet folder and choose get info. Make sure the number listed as Octal Mode Representation is 0711.
  • Right click on your individual html files within the pub_http_internet folder and choose get info. Make sure the number listed as Octal Mode Representation is 0644.

Using the command line:

  • Creating the appropriate directories: 
    • Note: new accounts will already have the necessary directories.
    • To get started: in your puma/gila home directory, use the following commands to create the folders and give them and your home directory appropriate permissions:
      cd
      chmod go+x-rw .
      mkdir pub_http_internet
      mkdir pub_http_intranet
      chmod go+x-rw pub_http_internet
      
      
       Note: the chmod commands above will also prevent other users on our system from perusing your home directory, which is generally a good idea. However, other users can still access files/directories if they already know the name. To further secure your account, you can remove read permission for all files in your home directory:
      cd
      chmod go-rw *
       You will have to repeat this step each time you add a file to your home directory. (An alternative is to create a subdirectory, e.g., "private", and put all your personal files in there.)
    • Inside each of those folders, create a file called index.html, which might contain:
      My first web page.
       After saving the file, ensure it has public read permission:
      chmod go+r index.html


6.2. Change your Profile and Office Hours Information on our Website

Profile Page

Our website lists Department personnel in the People menu.  A profile page is generated for each individual that looks similar to this:


You can change some of this information.  Please note that some items will be different depending on whether you are faculty, staff, or student.

 

STEP ONE:  In a web browser, go to https://omicron.math.arizona.edu/profile/.  Log in with your UANetID and corresponding password.

 

Research Groups

When the word Faculty is highlighted, you will see an interface that allows you to add or remove your affiliation with our research groups.  This will change the information on the http://math.arizona.edu/research pages.





Preferred Name, Title, and Zoom Information


If you click on the word Personal at the top of the page, you will be able to edit your preferred name and University of Arizona titles. This affects the information listed in our directories in the People menu.  Position titles are pulled from the University database. If you feel your title(s) are incorrect, please contact the Business Office.




NEW!  If you would like to publish your personal Zoom room information, put it here under Zoom Preferences.  

This information will only be visible by a person logged in with UA NetID.


The red icon over the Zoom Link icon indicates that the viewer is not logged in via NetID.  If they click on the icon they will be prompted to log in



Now that the person has logged in, they will be able to click on the Zoom icon and it will take them directly to the Meeting Room.


Office Hours

If you click on Office Hours you will be able to submit your Office Hours schedule. 


  • Click on the squares you wish to mark as office hours.
  • At the bottom you may put Additional Notes.  You may put your Zoom meeting link there, however it will be visible to the public.  If you prefer, you may put your Zoom personal meeting link in under your personal profile page (see above).  The zoom information submitted this way will only be visible to UA NetID holders.  
  • Click on the Submit Office Hours green button when done.



Your office hours will now appear in your profile.  Go to  https://www.math.arizona.edu/people  and click on your name to see them.

7. Remote Access to Math Accounts

7.1. Remote Access

There are three different types of remote access supported by the Department of Mathematics:

  • Mathematics Virtual Private Network (VPN)
    The Mathematics VPN allows you to access restricted Math resources (as well as many campus-only resources) when you are not in a Math building. For example, if you need access to the Mathematics Intranet pages, you could use the Mathematics VPN to gain access to them.

  • Remote Desktop (VNC)

    Using remote desktop, you can connect to a virtual Linux desktop from your Windows, Mac OS, or Linux-based computer. You can even connect from a tablet such as an iPad!

  • Shell Access (ssh)
    Shell access provides you with text-only access to your account. This is a great option for those who simply want to run programs or scripts from the Linux command line.


7.2. Mathematics VPN -- Virtual Private Network

The Mathematics VPN allows you to access restricted Math resources when you are not in a Math building using the Math wired ethernet. For example, if you are at home and establish a connection to the Math VPN, you will be able to get to the Office Hours submission page.   Additionally, you will be able to get to most U of A resources that require the UITS (University) VPN. For example, UAccess Instructor will be available for you while you are connected via the Math VPN. Do not attempt to use the UA VPN and Math VPN simultaneously.

Math VPN Setup Instructions:


7.3. VNC - Remote access and control of your Linux Desktop Environment

 

Note: 9/2014 - Due to the new version of Ubuntu (14.04) on our gateway machines and servers, you may need to update a file so that  your vnc desktop will appear properly. If you have a problem viewing your desktop: 1) Kill your vncserver process, 2) In your ssh terminal window, remove the following file:  ./vnc/xstartup (i.e. rm ~/.vnc/xstartup) 3) Restart the vncserver.

What is VNC?

VNC stands for "Virtual Network Computing" and is a type of "remote desktop" software. VNC lets you access to a Linux desktop running on a Math server in a window. This desktop is  called a "VNC server." It will run until it is killed. You connect to or "view" your personal virtual desktop from a "VNC client". You can disconnect and the desktop will continue to run. You need "VNC client" software on your Mac OS X, Windows, Linux machine or tablet to use this service. (See www.realvnc.com and at www.tightvnc.com for VNC clients.)

Our VNC Gateways: Phoenix (grad students) and Dragon (faculty) provide graphical access to your network account desktop from anywhere on the internet.

Since the gateways have many users, Please run computational software(e.g. Matlab) on the chivo cluster for graduate students, or on faculty desktops instead of on the gateways.

1. Set up your VNC Service

Before you can connect, you must setup your VNC service.

2. Connect to the VNC Service

2.1 Create a virtual private network (VPN) connection

If you are connecting from off campus, you must first connect to the Math VPN, the UA VPN or use SSH Tunneling

2.2 Installing the VNC Viewer

The VNC Viewer is a program you run on your local machine which connects to the remote VNC desktop so you can interact with it.

Windows and MAC

  • Microsoft Windows VNC Viewer - TightVNC Viewer [Download]
  • Mac OS X VNC Viewer - Chicken of the VNC  [Download]

Linux

  • If you are connecting from a linux computer, the vncviewer program should be pre-installed.

2.3 Connect the VNC viewer to the VNC server

Now you will connect to the remote VNC desktop you setup in step 1. 

Launch the viewer (e.g. tightvnc.) For the host connection, use:

   hostname.math.arizona.edu:59xx

Where "hostname" is the server you ssh'ed to and xx is the VNC number that displayed when you setup your VNC Service.

If you are connecting from a linux computer, VNC can be launched from the command line with the following command:

   vncviewer hostname.math.arizona.edu:59xx

You will also be asked for the VNC password you created at that time.  If you forgot the password you can reset it.

3. Disconnect from your VNC session

To disconnect from (i.e., stop viewing) your remote desktop, simply close the viewer (the outermost window).

There is no need to close individual windows inside your virtual desktop, nor is there a need to log out of the Gnome session inside your virtual desktop. (In fact, if you accidentally do this, then you must kill your remote desktop and create a new one.)


7.4. Setting Up Your VNC Service


  • The following steps show you how to set up your own persistent VNC server (i.e. remote desktop) which will run  on a computation server or a  VNC gateway.   When you are done with these steps, you will connect  to the server to start a computation job or access your math network files. 

    Setup: starting up the VNC server

    First you will create a VNC server (i.e. virtual desktop.) You can leave the VNC Server running for weeks or months. However, Please do not run multiple VNC servers on the same machine, or on multiple chivos.

    • Pick a VNC host.
      • For light work via VNC, we provide Phoenix (grads) and Dragon (faculty.)
      • For heavy computation, faculty can use their office desktops, grad students can use the chivos
    • Use SSH to connect to the VNC host. You will need to maintain either a Math VPN connection or a SSH Tunnel to the VNC host while using your vnc viewer.
      • For VNC via Math VPN ,
        • First connect to the MATH VPN
        • Then ssh to the machine (ssh to yourmathaccount@vnchost.math.arizona.edu) Replace vnchost with the machine you are connecting to (e.g. chivo, chivoX, yourdesktopname, dragon or phoenix.)
      • For VNC without Math VPN you will instead create an SSH session w/ Tunneling.
    • Use the command vncserver on the VNC host to create your remote desktop. The command will display the number of your new VNC server. EG: ":7", or ":13". You must remember that number! (Advanced users can specify additional options to vncserver. See the bottom of this page for information.)
    • Your remote desktop is now alive! You can use a VNC viewer to connect to your remote desktop.
    • You will be prompted to set a vnc password the first time you create a session. You will need to use this password every time you connect. If you ever forget this password, you can reset it.

    Setup: starting up the VNC server on Ubuntu 16.04 (e.g. the grad chivos).

    VNC server configurations that work on older versions of Ubuntu may not work on Ubuntu 16.04.  If you start your VNC client and see nothing but a grey screen after connecting to the VNC server, follow these instructions to fix the problem.

    • Decide whether you want an xfce4 or a gnome desktop.  The gnome desktop will probably look more familiar, but the xfce4 desktop will be faster and more responsive.
      • If you decide to try the xfce4 desktop, backup your current ~/.vnc/xstartup file and replace the contents with this:
        #!/bin/sh
        
        startxfce4 &

  • If you decide to stick with the gnome desktop, backup your current ~/.vnc/xstartup file and replace the contents with this:
    #!/bin/sh
    
    export XKL_XMODMAP_DISABLE=1
    unset SESSION_MANAGER
    unset DBUS_SESSION_BUS_ADDRESS
     
    gnome-panel &
    gnome-settings-daemon &
    metacity &
    nautilus &
    gnome-terminal &
After updating your xstartup file, make sure execute permissions are set on it:
bobburton@chivo:~/.vnc$ ls -ld xstartup
-rwxr-xr-x 1 bobburton users  24 Feb 13 10:35 xstartup
Kill your current VNC server process if you have one:
bobburton@chivo:~/.vnc$ ps -ef | grep vnc | grep bobburton
bobburt+ 24506 1 0 08:57 pts/8 00:00:00 Xvnc4 :2 -desktop chivo:2 (bobburton) -httpd /usr/share/vnc-java -auth /u5/bobburton/.Xauthority -geometry 1024x768 -depth 16 -rfbwait 30000 -rfbauth /u5/bobburton/.vnc/passwd -rfbport 5902 -pn -fp /usr/X11R6/lib/X11/fonts/Type1/,/usr/X11R6/lib/X11/fonts/Speedo/,/usr/X11R6/lib/X11/fonts/misc/,/usr/X11R6/lib/X11/fonts/75dpi/,/usr/X11R6/lib/X11/fonts/100dpi/,/usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi/ -co /etc/X11/rgb
bobburton@chivo:~/.vnc$ vncserver -kill :2
Killing Xvnc4 process ID 24506
bobburton@chivo:~/.vnc$
Restart the VNC server:
bobburton@chivo:~/.vnc$ vncserver -geometry 1680x1000 -depth 24
Found /usr/share/vnc-java for http connections.

New 'chivo:2 (bobburton)' desktop is chivo:2

Starting applications specified in /u5/bobburton/.vnc/xstartup
Log file is /u5/bobburton/.vnc/chivo:2.log

bobburton@chivo:~/.vnc$

  • Many warnings will be spewed to the log file, e.g. ~/.vnc/chivo1:2.log, but none prevent the desktop from running.

How to reset your vnc password

Use ssh to connect to any networked linux machine (e.g.  phoenix, dragon or a chivo) and enter the command "vncpasswd." You will be prompted for a new password.

How to figure out your desktop number

If you've forgotten your desktop number, you can connect to the VNC host via ssh then issue the command:

ps -ef | grep vnc | grep myusername

How to permanently kill your remote desktop

To kill your remote desktops, first use SSH to connect to the VNC host, as described above. To kill a particular desktop, for example desktop number 7, use the command:

vncserver -kill :7

To kill all your desktops at once, use the command:

killall Xvnc4 

You can ignore any "Operation not permitted" error messages.

Advanced VNC Hints

  • The simpler the graphics on your desktop, the less information needs to be transferred, and the faster your VNC connection will be.       
    • Change your desktop background color to a solid color. Use solid white or solid black.
    • Simplify your desktop theme to one that uses rectangular windows, and uses a solid color (as opposed to gradient shading) for controls, window titles, etc.
    • Turn off any graphics, like moving charts or eyeballs that follow the mouse cursor...
  • To make VNC it as fast as possible you can use a smaller desktop, and use fewer bits per pixel. For example: vncserver -depth 8 -geometry 800x600.
  • When you create your VNC server with the command vncserver, you can use a different resolution and/or color depth. You can match your vnc screen resolution to that of your home computer and run your VNC viewer in fullscreen mode.       
    • For example, say your Windows box at home has a display resolution of 1280x1024 at 24 bits/pixel. (To see this information, right-click on the background of the desktop and bring up Properties.)
    • When you create your VNC server, you could use the command vncserver -depth 24 -geometry 1280x1024. (see "man vncserver" for more info.)
    • When you connect from your Windows box, right-click on the titlebar of the outermost VNC window and select "Full Screen". It will tell you the keystrokes to escape from full-screen mode.
    • At this point, instead of seeing Linux inside a VNC window inside Microsoft Windows, all you see in front of you is your remote Linux desktop!
  • Please disable the screensaver on your remote desktop. (Otherwise your virtual desktop will use too many CPU cycles "saving" a non-existent screen.) On our remote desktop gateways, the screensaver has already been disabled - but if you run a VNC server on some other computer, then the first time you connect to your remote desktop, disable your X screensaver (go to Start/Programs/Settings/Desktop/Screensaver).

7.5. Alternatives to VNC

VNC is overkill for many applications.  If you're running Matlab or Mathematica on a Linux server, you don't need to replicate your Linux desktop on your local computer--it's sufficient to just open the windows required by the application.


This can be accomplished by running an X server on your local computer and connecting to the Linux server with secure X11 forwarding enabled.  This can be done from Windows, OS X, or Linux clients.  The following instructions were plagiarized from https://uisapp2.iu.edu/confluence-prd/pages/viewpage.action?pageId=280461906.  If you are not in a Math building using the Math wired ethernet,  connect to the Math VPN before starting.


Windows

  1. Install the Xming software.
  2. If you have not already done so, download putty.exe from the PuTTY site and install it.
  3. Run Xming on your PC to start the X server.  You should see the Xming icon in the taskbar if it is running (although you may have to click the little arrow in the taskbar to see it)
  4. Run PuTTY and set things up as follows:

    - Enter the server name (e.g. chivo.math.arizona.edu) in Host Name
    - Make sure the Connection type is set to SSH
    - Enable X11 forwarding (Connection > SSH > X11)

  5. Log in with your Math username and password.
  6. Once you are logged into the linux system, you can just run the GUI program of your choice (ie. Matlab, Mathematica, etc) from the command line and it will display on your PC.


Mac OS X

  1. Install XQuartz on your Mac, which is the official X server software for Mac
  2. Run Applications > Utilities > XQuartz.app
  3. Right click on the XQuartz icon in the dock and select Applications > Terminal.  This should bring up a new xterm terminal windows.

  4. In this xterm window, ssh into the linux system of your choice using the -Y argument (secure X11 forwarding).  For example, to log into chivo.math.arizona.edu you would run something like:

    ssh -Y username@chivo.math.arizona.edu

  5. Once you are logged into the linux system, you can just run the GUI program of your choice (ie. Matlab, Mathematica, etc) from the command line and it will display on your Mac.


Linux

  1. Ssh into the linux system of your choice using the -Y argument (secure X11 Forwarding).  For example, to log into chivo.math.arizona.edu you would run something like:

    ssh -Y username@chivo.math.arizona.edu

  2. Once you are logged into the remote linux system, you can just run the GUI program of your choice (ie. Matlab, Mathematica, etc) from the command line and it will display on your linux client.

7.6. Remote Shell Access to Your Network Account

Our shell gateways, reachable worldwide from anywhere on the internet, provide text-only shell access to your network account. (Once on the gateway, you can also connect to other machines in our building network.)

  • Faculty/visitor/staff shell gateway: ssh -p 31415 dragon.math.arizona.edu
  • Graduate student shell gateway: ssh -p 31415 phoenix.math.arizona.edu

You use ssh to connect to our shell gateways.SCP, and SFTP are also used to transfer files between your network account and other systems.

Your SSH program uses port 22 by default. You will need to set it to use port 31415 when you are not in a Math building. 


Please never run heavy-duty computations directly on the shell gateway. If you are running a compute job you should ssh or VNC to another machine (such as your office desktop, or the chivo cluster for graduate students)

Different ways to connect to the shell gateway:

  • If you are running Microsoft Windows download putty:
    • PuTTY [Download], [How to use]
      This elegant tiny SSH client is a quick download and does not require an Installer to be run.
  • If you are running Linux or Mac OS X, you can run ssh from the command line, e.g.:
    ssh -p 31415 accountname@dragon.math.arizona.edu

Gateway authentication:

To verify that you are not being duped by a rogue gateway, the first time you try to connect you will be presented with the gateway's RSA or DSA key fingerprint. The correct fingerprints are:

dragon (RSA): ec:0d:8f:56:ff:60:cc:99:69:81:72:13:e8:c7:08:e2
dragon (RSA/Babble): xipod-ryzem-tefud-nevip-nudef-zinoc-mycyk-gucam-kohiz-pucam-boxex

7.7. Running software remotely or in the background

Introduction

If you're doing heavy-duty computation with Matlab/Maple/Mathematica or your own programs, you may have to wait a long time (perhaps days) for your computation to finish. Since you don't want to sit in front of a lab computer for days, or tie up your office computer, you can put tasks in the background, and/or put them on a remote machine. You can then log out and return later to  get your results,  Note that it is very easy to take up too much CPU time or memory with a background computational process. The "chivos" are dedicated to this purpose for grad students.

Commands

Before launching background/remote tasks, you must:

  • Learn to use ssh to connect to remote systems.
  • Learn to use top or pskill, and renice to monitor and manage processes you've started.
  • Learn to use &nicenohup, and ulimit to launch processes in a desired way.
  • For interactive (non-batch) programs: know about ssh -Y, and learn either vnc or screen.

You can type "man command" to get more information on any of these commands.  This article also gives a nice overview.


top

top displays a list of active processes, how much memory and CPU time each process is using and who owns it, etc. If a machine is sluggish, top will tell you why! From within the topdisplay, you can  kill or renice your running processes. Hit ? for some help, and read the manpage: man top. (If you spot someone else's runaway process eating too much CPU, you can email system or the other user . They might not know about it unless you inform them.)

ps

Makes a list of running processes along with additional information. A common invocation isps -aux, which lists a lot of extra information. Another useful invocation is ps -aux -forest, which draws lines to indicate which process spawned which process. (The commandpstree is similar.)

kill

Lets you kill one of your processes. You must know the numeric process ID. You can see the PID in the top display, or you can get a list using ps -aux. Instead of using kill as a separate command, you can access it inside top. Read man kill for more info. Generally you can first send a "kill 15 xxxxx" (where xxxxx is the process ID) and wait a few seconds.  If the process does not die, do a "kill 9". If that doesn't work, then that machine has become unstable and you can contact the computer support staff.

nice

This starts a task with a nice value, which means the task will do a better job sharing the CPU when you try to run other programs or when other users log in to the same computer. All heavy-duty tasks not running on chivos should be nice. Manpage: man nice.

renice

Forgot to start something using nice? Use this to go back and make it nicer. You can also do this inside top.  See: man renice.

&

Putting this after a command puts that command in the background, so that you can continue to give other commands. If you log out, your background task might get killed automatically (to avoid that, see nohup).  If the command  creates windows (e.g., Mathematica &), it will create them even from the background. Most people use & when starting programs like Mathematica so that they don't lose their prompt. (Try it both ways and the previous sentence will make more sense.) See: http://en.wikibooks.org/wiki/A_Quick_Introduction_to_Unix/Job_Control

nohup

To put something in the background so that it doesn't die when you logout, start it with nohup. (e.g. "nohup command &"  ) This works with text-only programs. In other words, the "nohupped" command won't work if it tries to create windows, or needs keyboard input.  The command must send all output to a file. You can use this with your own C/C++ programs, but you can't use it with most software packages. See: man nohupscreen does much more than  nohup.

ulimit

To prevent a program from using too much time or too much memory, you can set limits in a shell, and all programs started from that shell will have those limits imposed. Use ulimit -ato get a list of limits. To confirm you understand what is going on, set various values ridiculously low and try to run your program to make sure it gets stopped by the operating system. Then quit that shell, open a new shell, and set more reasonable limits. Go read man ulimit.

screen

This creates an environment in which you can start an interactive text-only program, such as GAP or Macaulay, or even Mathematica in its text-only non-notebook mode, but you can log out and it keeps going. On any linux machine, e.g. chivo, enter screen, a "screen" process starts with a new prompt. Then you can enter a command, e.g:  nice Singular, then type some Singular commands that will take days to complete, hit "control-A d" and log out. A day later you can ssh  to chivo, do screen -r to reconnect, and you'll be right back in the Singular session. It's very cool. Type man screen on a linux machine for more information or see this short tutorial for more information on using screen

ssh

From within a shell, you can use ssh user@remote to obtain a shell on a remote system. Then you can issue commands (such as many of the ones described on this page) on the remote system. If you use ssh -Y user@remote then there will also be interactive X forwarding, meaning that programs launched on the remote system can open windows on your local system (assuming you are logged in to a graphical X desktop). You might also want to read about using ssh to obtain remote shell access to your network account.

VNC

This is a graphical version of screen. You can create an entire virtual X desktop and connect to it from home, office, anywhere you can access a web browser. You'll have to read man vncserver and man vncviewer. You might want to read about using vnc to obtain remote desktop access to your network account.


7.8. Transferring Files To/From Your Network Account

 

Our shell gateways can be used to transfer files to/from your network account.

Technically speaking, our shell gateways speak SSHSCP, and SFTP. To use RSYNC, layer it over SSH: rsync -e 'ssh -p 31415' ....

When connecting from outside the department, you must connect on port 31415. 

To connect and transfer files:

  • If you are running Microsoft Windows you can use WinSCP. [Download]
  • If you are running Mac OS X we recommend Fugu. [Download]
  • Alternatively, if you are running Linux or Mac OS X, you could instead invoke scp directly from the command line to transfer individual files:
    scp -P 31415 localfilename myaccountname@dragon.math.arizona.edu:newremotefilename
    scp -P 31415 myaccountname@dragon.math.arizona.edu:remotefilename newlocalfilename
     To transfer many files, you may want to instead enter an interactive SFTP session:
    sftp -oPort=31415 myaccountname@dragon.math.arizona.edu
     (You will need to know how to use SFTP commands.) 

    Gateway authentication:

    To verify that you are not being duped by a rogue gateway, the first time you try to connect, you may be presented with the gateway's RSA key fingerprint. The correct fingerprints are at the bottom of our page on remote shell access.


7.9. WinSCP for File Transfer

After you open WinSCP you will see a login screen. The hostname will be dragon.math.arizona.edu for faculty/staff or phoenix.math.arizona.edu for graduate students. The port number of 22 is fine, unless you are not on the math network. In that case change the port to 31415


Next you might see a warning like the following:

Finally you get to the transfer file window. You can drag and drop files from your computer (left side) to the server (right side). Files for your webpage should go into your pub_http_internet folder.




7.10. How to Use PuTTY to Connect to a Remote Computer

Start PuTTY by double-clicking its icon.


When a PuTTY Configuration window opens select Session (it should be selected by default) from the Category panel on the left. In the Host Name (or IP address) field enter the name of the computer you wish to connect to. In the Port field replace 22 (the default) with 31415. Make sure that SSH is selected under Protocol (it should be selected by default). Click on Open.


In the new dialog box enter your username and password.


Once you see the prompt, you are connected to the remote computer.

7.16. VNC via SSH Tunneling

How to create your remote desktop:

Before you can connect to your remote desktop, you must create your remote desktop service.

Different ways to connect to your remote desktop:

In the instructions below, wherever we write "bobcat", graduate students should substitute "iguana".

  • If you are running Microsoft Windows you'll need both an SSH Client and a VNC Viewer.
    • PuTTY - SSH Client [Download]
      You'll need to make sure you have PuTTY setup for SSH Tunneling.
    • TightVNC Viewer [Download]
      Note that you only need the "Viewer", which is the smallest of the many available downloads. To connect, first launch PuTTY and open the session you created using the instructions above. Then launch the viewer, and simply type "localhost" for the Remote Host. If your SSH Tunnel is set up properly and connected, you will be asked for the password you setup when you created your remote desktop service.
  • If you are running Linux or Mac OS X, you can create your SSH Tunnel directly from the command line:
  ssh -L 5900:bobcat.math.arizona.edu:59xx -p 31415 bobcat.math.arizona.edu

where xx is your VNC desktop number.

  • For Mac OS X, you can download the client "Chicken of the VNC". While logged in with the previous command, you can run "Chicken of the VNC" and enter "localhost" for the host and the password you setup when you created your remote desktop service.
  • For Linux, while logged in with the previous command, open a new terminal window, and enter the following command:
  vncviewer localhost

How to disconnect

  • To disconnect from (i.e., stop viewing) your remote desktop, simply close the viewer (the outermost window).
  • There is no need to close individual windows inside your virtual desktop, nor is there a need to log out the Gnome session inside your virtual desktop. (In fact, if you accidentally do this, then you must kill your remote desktop and create a new one.)


7.17. PuTTY - SSH w/ Tunneling

Start PuTTY By click on this icon:


You will be presented with the PuTTY Configuration window below.


Enter the name of the computer you're creating this connection for. An example would be "dragon.math.arizona.edu". Enter 31415 for the port. Then since we are creating a session we intend to re-use, enter the computer name in the Saved Sessions space as well. Once all that's entered click on the Save button to the right.

Next, click on the plus sign next to the words "SSH" on the left, then click on "Tunnels" from the items that appear below it. That should bring up a window that looks like this:


Enter the Source port of 5900 and the Destination as dragon.math.arizona.edu:59xx, where xx is your VNC desktop number. If you don't have one, you'll need to create your remote desktop service. Then click "Add" and make sure that your tunnel settings appear in the box above where you entered them.
Note: Graduate Students will use phoenix instead of dragon.

Next, you need to scroll the "Categories" box on the left back up and click on "Session". You'll be taken back to the first window. Click "Save" here again to save your Tunnel settings to the Session we've created.

Now you can simply click Open, and an SSH connection will be made with a Tunnel from your localhost to the Destination entered above. In the future, when you open SSH, you will be able to simple double click on the server name in the Saved Sessions window to open the connection.


7.18. Connecting to Math VPN - Mac OS Sierra and above

  • Go to the Apple Menu and choose System Preferences

  • Choose Network

  • Click the plus sign 

  • Interface: chose VPN
  • VPN: Cisco IPSec
  • Service Name: Math VPN (Cisco IPSec)
  • Click Create

  • Click the Authentication Settings button
  • Shared Secret can be found here
  • Group Name is:  Musers
  • Click OK

  • Next fill in the following...
  • Server Address: vpn.math.arizona.edu
  • Account name:  Use your math username
  • Password: This will be your math password, you can leave this blank and it will ask for it later when you connect.
  • Put a check in the box for Show VPN status in menu bar.
  • Click Apply, and then Connect.


After set-up:

  • You can still connect though System Preferences/Network, but it is easier to use the shortcut.
  • In the upper right you should see an icon that looks like this:

  • Click on it to see this menu:

  • Choose connect
  • When you are finished, you can also choose Disconnect from this same menu.


7.19. How to Use PuTTY to Connect to a Remote Computer

Start PuTTY by double-clicking its icon. 


When a PuTTY Configuration window opens select Session (it should be selected by default) from the Category panel on the left. In the Host Name (or IP address) field enter the name of the computer you wish to connect to (such as dragon.math.arizona.edu or phoenix.math.arizona.edu). In the Port field replace 22 (the default) with 31415. Make sure that SSH is selected under Protocol (it should be selected by default). Click on Open.


In the new dialog box enter your Math username and password.


Once you see the prompt, you are connected to the remote computer.





8. Software

8.1. Math Software Information

There is a lot of math-related software on our systems. We try to install all major systems that are free of charge, and the department furthermore pays for Maple, Mathematica, and Matlab. On this webpage, we list some specific quirks or other local matters that have arisen.

Matlab MCC

On Linux systems, the Matlab command-line tool mcc conflicts with the similarly-named tool that is part of Mathematica. Since the Matlab tool is more commonly used, the command mcc should invoke the Matlab tool. However, to ensure you've got the correct tool, instead use the command mcc-matlab.

Mathematica MCC

On Linux systems, the Mathematica command-line tool mcc conflicts with the similarly-named tool that is part of Matlab. Since the Matlab tool is more commonly used, the command mcc does not invoke the Mathematica tool; instead, use the command mcc-mathematica.

Mathematica Activation

Mathematica needs to be activated the first time you run it. At the bottom of the activation window select "Other ways to activate". On the next window, select "Connect to a network license server". Then enter vm-ls-mathematica.math.arizona.edu as the "Server name" in the final window. More information can be found here: http://reference.wolfram.com/language/tutorial/ActivatingMathematica.html.

9. Networks

9.1. Available Networks

Math Network -

This refers to the wired Ethernet network in the Math Tower, Math Teaching Lab, and ENR2.   This network is managed by the Math IT Staff.  Personal computers will need to be registered with us to gain access to the "Trusted Net".  If you are plugged into this network and on the Trusted Net, you will have easy access to certain Math resources, such as the Konica Minolta Printer/Copiers.


Wireless Network-

The University maintains the UAWiFi and UAGuest networks.  If you are on one of these, you are not on the Math Network.  If you want to access services available only on the Math network, but don't want to plug in, you can use the Math VPN.


Visitors to the Department-

Visitors can plug into the Math network and still access services (such as the internet) that are not on the Trusted Net.  For wireless, they can log on to UAGuest or use Eduroam (if they belong to a member institution).

9.2. Using Personal Equipment

 

You are welcome to use your own personal computing equipment while working within the Department of the Mathematics. However, any personal machine connected to the Mathematics Department network (wireless or otherwise) must comply with the University Computing Standard as well as all departmental computing policies.

Please visit the links to the right for information about getting online and available software.


10. Computers and Laptops

10.1. Computers and Laptops

The University provides one-time start-up assistance to new tenure-track faculty, under which the Mathematics Department obtains an office computer (with 3 years of hardware warranty support).

The University does not (May, 2002) provide replacement computers (after the initial start-up support) for its faculty. Tenure-track faculty members are encouraged to submit proposals for support of research activities.


10.2. Personal Equipment - Antivirus and Malware

Installing Sophos Anti-Virus:

  1. Go to https://softwarelicense.arizona.edu/sophos-central and follow the Home Use instructions.  You will be asked for your UANetID and password.
  2. Select Sophos Home Free and Download Now and follow the instructions.

Removing Malware

Malware, short for malicious software, is any software program designed to cause harm to a computer system or designed to frustrate the user experience. In addition to viruses and trojan horses, this category of software includes spyware and adware. In short, malware constistutes all the software that evil people try to sneak onto your computer, but which you do not want to have on your computer. This page describes the three programs you should run to eliminate malware from a Windows system. (For more information on malware, see the Malware Wikipedia entry.)

Run Malwarebytes Anti-Malware

This program, which has a free version, does a good job of removing malware. Please download malwarebytes, and then install/run the software.

Run Sophos Anti-Virus

See instructions above.

Run Lavasoft Ad-Aware

  1. Download Lavasoft Ad-Aware.
  2. Install/run the software and initiate a full scan of your system.
  3. On the screen in which you are presented with a list of suspicious objects, you must manually select all the ones you wish to have removed. Unless a suspicious object leaps out at you as being something important, chances are that you want to remove all the suspicious objects that were found. To quickly select all objects, right-click one of the checkboxes and select the appropriate choice from the menu
  4. that will pop up. Click onNext to continue to the next screen and remove the objects. 
  5. When the confirmation dialog appears, click on OK


10.3. Getting Online-Register your laptop or other personal equipment with our network

How to register your laptop or other personal equipment with our network

If you would to be added to our "trusted" network so that you can use Math Department printers or access the Math Department intranet, you must:

  • Ensure your equipment has all malware removed and is running up-to-date virus/malware protection software. You may purchase your own, or at no cost to you make use of the university-provided automatically-updating Sophos Anti-Virus.
  • Configure your equipment to obtain a network address automatically (via DHCP). Most equipment is configured this way by default.
  • Have us register your network interface MAC addresses (all equipment has these - the term "MAC" does not refer to Macintosh) with our DHCP server. Note that you may have multiple MAC addresses (for example, one for your LAN connection, one for your wireless connection). See below on how to obtain your addresses, then send the information to the computer support staff. (If you are unable to determine the necessary information, then we will be happy to inspect your equipment ourselves. Please contact us to arrange a time.)

Registering for rest of campus

To use personal equipment in areas of campus controlled by UITS, which includes the student union, the campus library, and the ILC, you'll need to register it with UITS. This does not apply to wireless access. There is no registration required for wireless access, but you will need a UA NetID to connect via the UAWiFi connection. UAGuest does not require NetID, but it is not secure and does not allow certain types of connections.

  • Students: you can do this by following the instructions on this page.
  • Faculty, Visitors, and Staff: you must ask us to register your equipment with UITS on your behalf. In your request, include the same MAC address information discussed below.

How to obtain your MAC addresses:


Microsoft Windows

Open a DOS prompt and use the command ipconfig /all. As in the screenshot below, look for Physical Address on your LAN and/or wireless adapter, but ignore the PPP (dial-up) adapter if there is one.



Linux 

Use the command ifconfig or /sbin/ifconfig. As in the screenshot below, look for HWaddr on your LAN (often eth0 or en0) and/or wireless (often wlan0 or ath0) adapter.



Mac OS X

Go to the Apple Menu and choose About This Mac:



Click on System Report...



Choose Network on the left, then Ethernet at the top, and find the Ethernet MAC Address below.



11. High Performance Computing

11.1. High Performance Computing

High Performance Computing

Chivo Machines

If you wish to execute long-running compute jobs, the Mathematics Department provides remotely accessible systems dedicated to this purpose, known as "Chivos." (Since they are named "chivo" and chivo1 through chivo4).

Math software packages are installed on these machines.
