3.2. 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 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


3.3. 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.

3.4. Network Account Management

3.5. Passwords

Mathematics Network Account Password Change Procedure:

  1. Click on the following link: change your password
  2. Enter your username (NOT your whole email address) 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


3.6. 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.

3.7. Network Account and Math Email Removal

 Math Department Policy on Account Termination

Please Note:  These policies are likely to change soon due to new security requirements mandated by the University!  We suggest moving your email and files and closing your account as soon as possible after you leave.  See this article for transfer information.

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. How do I know if I am using Backup and Sync from Google?

These instructions are for Windows 10.

  • Look for this cloud symbol at the bottom right part of your screen near the clock.  

  • If you don't see it right away, click on the up caret 

  • If you see the cloud symbol, then you know Backup and Sync is installed. BUT, you may not be actually using it.  You can check if you are logged  into the Backup and Sync app.  Hover your cursor over the cloud symbol.
  • If you see the following "not signed in" message, then you are NOT logged into the app and NOT syncing files.

  • If you see anything like the following two images, then you ARE logged in and using the app.

If you are not using it, you will eventually be prompted that it is not supported and asked to remove it.  If it is a department machine and needs an admin login for removal, email

If you are using it, it is time to switch to Google Drive for Desktop. Right-click on the cloud symbol as shown  above.  Choose Get Started and refer to this article:

5.2. Setting Up Google Drive for Desktop to Replace Backup and Sync

If you have determined that you are using Backup and Sync from Google (See this article for more info: ) and need to switch to Google Drive for Desktop, follow these steps.  (These are for Windows 10)

  • Right click on the Backup and Sync Cloud symbol and choose Get Started

  • Sign in with your and corresponding password

  • It will proceed to check for folders that were backing up or syncing in the current system.



  • This next step is important.  The "My Drive" it is referring to is  your Google Drive (in the "cloud").  When you go to in your web browser, it is here:


  • This is potentially a lot of files.  You probably don't want to have a duplicate copy of them on your local hard drive.  Therefore, in the next step you should probably choose Stream
    • Here is some more info on the difference between Stream and Mirror:
      • When you mirror files, all of your My Drive files are stored in the cloud and on your computer, which takes up hard drive space. All of your files will be accessible at any time, even when you don’t have an internet connection or the Drive for desktop  app running. Files can be accessed through a folder on your computer. 
      • When you stream files, your My Drive files are stored in the cloud. Hard drive space is only used when you open files and make them available offline. Files that are not available offline can only be accessed when you’re connected to the internet. All files, including those available offline, can be accessed only when the app is running. Files can be accessed through a mounted drive on your computer. 



  • When it is done it will prompt you to remove Backup and Sync.  Click OK.

If you do not have admin rights on your computer you will see the following.  If the computer belongs to Math, email and we will remove it for you.

Now what?

  • Now when you look at This PC , you will see a letter drive (probably G:). This is a stream of your My Drive files.  They are still in the cloud.  You will need to be on the internet to access them.

5.3. Google Apps for Education - Math

Note:  Math Google Apps for Education will be retiring Summer 2024

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. UA VPN for Math Dept

7.4. 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 and at 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]


  • 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:

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:


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.)



7.5. 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 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:
        startxfce4 &

  • If you decide to stick with the gnome desktop, backup your current ~/.vnc/xstartup file and replace the contents with this:
    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
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


  • 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).

connect  to the server

7.6. 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  If you are not in a Math building using the Math wired ethernet,  connect to the Math VPN before starting.


  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. 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 >
  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 you would run something like:

    ssh -Y

  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.


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

    ssh -Y

  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.

7.7. 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
  • Graduate student shell gateway: ssh -p 31415

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

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 
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

7.8. Running software remotely or in the background


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:

  • 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 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:


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.


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.


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.


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.


7.9. 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
    scp -P 31415 newlocalfilename
     To transfer many files, you may want to instead enter an interactive SFTP session:
    sftp -oPort=31415
     (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.

7.10. WinSCP for File Transfer

After you open WinSCP you will see a login screen. The hostname will be for faculty/staff or 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.

7.11. 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.

7.12. 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 -p 31415

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.)

7.13. 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 "". 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, 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.

7.14. 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 or 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.
