Math/CS Lab Links

When you need to do work in our computing lab, it is sometimes possible to do so remotely. In particular, a SSH client program lets you securely start a shell window connected to a lab machine. This non-graphical environment is already sufficient to edit, compile, test, and turnin many non-graphical programs. A related protocol (SCP) lets you to transfer files back and forth. And if you have a local "X server" on your machine, it is even possible to run graphical lab software remotely.

Windows users may choose between Tectia (distributed by ITD), the free PuTTY program, or the (large and Linux-like) Cygwin environment. On Mac's (OS X), Linux, and Solaris, ssh and scp are already available from the command line, try:

ssh myuserid@machinename
For more options such as forwarding an X session, or setting up a public key, see the online documentation (e.g.: man ssh).

For a list of lab machine names, see below. If a remote lab machine seems slow, you might try its top command to see if it is busy processing. However, slow response is usually due to network congestion, in which case switching to another lab machine won't help.

The Math/CS lab machine names are listed below, just pick one at random. If the lab seems to be unavailable for some reason, you may still access your lab home directory via ITD's public UNIX servers such as timeshare.service.emory.edu. But these ITD machines don't run correct versions of key software tools (compilers, java, etc.), therefore they are not useful for much except editing and file transfer. In particular, do not try to turnin homework from ITD machines.

Warning: It may also possible to connect to the lab machines using telnet, but we discourage that since telnet insecurely sends your password "in the clear".
