Logging into CSIL from MacOS or Linux

ssh -X pconrad@csil-21.cs.ucsb.edu

The first time you’ll get a message such as:

ECDSA key fingerprint is SHA256:ANJ7ced3JXpxKnu8OhnS3f8Z0rE9aIKA+eHHgVlEzVc.
Are you sure you want to continue connecting (yes/no)? yes

Just say yes.

Machines are 01-48

CTRL/D can be used to exit.

For Windows, the program is MobaXTerm

To use it, look for “New Session” in upper left,

Then “ssh” upper left.

Then enter csil-15.cs.ucsb.edu (or whatever number) where it asks for host.

Then, you’ll be prompted for username and password.

If you get this message when running idle3

or any other program that needs graphics…

_tkinter.TclError: no display name and no $DISPLAY environment variable

On Windows: Use MobaXTerm instead of a program such as PuTTY.

On Mac: You need to install XQuartz … go to XQuartz.org, download, follow instructions, and try again.

Also: on Mac or Linux, maybe you forgot the -X part.
