Congratulations, you have added the PaperCut printer(s)!
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.
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 network account.
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.
You can check how many print jobs you have left in your quota.
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."
You can cancel your print jobs by logging into the papercut server, follow these steps before swiping your catcard or logging into the printer.
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.

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.
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.
Before you can connect, you must setup your VNC service.
If you are connecting from off campus, you must first connect to the Math VPN, the UA VPN or use SSH Tunneling.
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
Linux
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.
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.)
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.
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.
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.

Many warnings will be spewed to the log file, e.g. ~/.vnc/chivo1:2.log, but none prevent the desktop from running.
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.
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.
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.
Right click on the XQuartz icon in the dock and select Applications > Terminal. This should bring up a new xterm terminal windows.
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.)
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:

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 dragon (DSA): 8f:4c:ca:06:1c:85:91:6c:60:b5:1f:05:50:8c:69:f5 dragon (DSA/Babble): xohon-nacyv-vivyb-tizuh-debem-narek-sipam-begin-fasys-zades-gaxux phoenix (RSA): da:7d:51:4e:b9:32:72:e9:ce:65:a5:cf:25:02:56:69 phoenix (RSA/Babble): xifel-kobid-lyrur-zazod-topaz-doniz-vogyh-bubug-malip-lyfym-toxux phoenix (DSA): f2:0a:b9:9e:3a:33:7a:cc:0e:ff:c6:18:97:70:b3:29 phoenix (DSA/Babble): xukit-nilor-sybyf-firyz-lonez-tored-teban-kuryd-suhez-davyf-luxix
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.
Before launching background/remote tasks, you must:
You can type "man command" to get more information on any of these commands. This article also gives a nice overview.
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.)
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.)
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.
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.
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
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 nohup. screen does much more than nohup.
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.
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.
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.
Our shell gateways can be used to transfer files to/from your network account.
Technically speaking, our shell gateways speak SSH, SCP, 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.
scp -P 31415 localfilename myaccountname@dragon.math.arizona.edu:newremotefilename
scp -P 31415 myaccountname@dragon.math.arizona.edu:remotefilename newlocalfilenameTo 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.)
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.
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.
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.
Before you can connect to your remote desktop, you must create your remote desktop service.
In the instructions below, wherever we write "bobcat", graduate students should substitute "iguana".
where xx is your VNC desktop number.
How to create your remote desktop:
Different ways to connect to your remote desktop:
You'll need to make sure you have PuTTY setup for SSH Tunneling.
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. ssh -L 5900:bobcat.math.arizona.edu:59xx -p 31415 bobcat.math.arizona.edu
vncviewer localhost
How to disconnect
Start PuTTY By click on this icon:
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.
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.

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.
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.)
This program, which has a free version, does a good job of removing malware. Please download malwarebytes, and then install/run the software.
See instructions above.
If you wish to execute long-running compute jobs, the Mathematics Department provides a remotely accessible system dedicated to this purpose, known as "Chivo".
Math software packages are installed on this machine. Chivo can be accessed from within the math building directly via vnc or ssh, or from outside the math building via Math VPN and then vnc or ssh. It can also be accessed from outside the math building via a Remote ssh access servers (i.e. Phoenix).
Chivo is outfitted with a Xeon processor and 32 GB RAM. You can execute jobs via VNC or shell commands. Please read our support page on how to run jobs remotely and in the background. The full machine name is:
