How to Connect to Math Research Machines

The math department has an assortment of server and workstations running Linux and specific math software designed to help with math research.  We call them Magma machines, as those are the only machines which have the program Magma installed, but they are not just used for Magma computations.  Matlab, Mathematica, Macaulay, and Maple are also installed.  Additional programs can be installed upon request.

1.  Do you need WiscVPN?
  • If you connect from off-campus, you'll need to use a WiscVPN connection first.  If you need the WiscVPN program, you can find it here:  https://uwmadison.vpn.wisc.edu.  Once installed, use the portal of uwmadison.vpn.wisc.edu and connect with your netid and netid password.
  • If you are connecting from on-campus, there's no need to use WiscVPN.
  • From a chromebook:  https://kb.wisc.edu/74637
2.  To connect, open a terminal window.
3.  Connect to the UW Math Department "portal".  
    
    People who have a math account should connect to our portal machine, bing.math.wisc.edu.
    
    If you are using a program like PuTTY or Secure CRT, you'll need to set up a connection to connect to it.
    If you are using a terminal program, you simply need to type

        ssh yourmathaccountname@login0.math.wisc.edu

    If you don't know your math account name, please contact staff@math.wisc.edu.
    
    Once you have successfully connected, you'll see something that looks like this...

4.  You can't run math programs for research from login0.  You need to hop to one of the research machines.

    Our current list of research machines can be found here.

    type the following from the bing> line

    bing> ssh magmaN

    where N is any number from 0-11.  

    Once you have successfully connected, you'll see this...

bing>ssh magma2
