Getting Connected via SSH
You can connect to the LinCompute Cluster using the ssh (Secure Shell) application. Connections from on-campus or using the UT VPN service can login using their UT EID and password. Machines can not connect from off-campus without VPN unless they use public key authentication instead of password authentication. In the instructions below, we assume you are either on-campus or using the UT VPN service.
Mac
Go to Applications > Utilities, and then open Terminal.
Establish an SSH connection to the server by using following command, where “your-eid” is replaced by your actual UT EID username: ssh -X your-eid@lincompute.cns.utexas.edu
The first time that you connect to the server, a message will ask you if you want to continue connecting. This message appears because the remote server has an ssh key that's not stored in your system registry and as a result, the identity of the key can't be verified. This is normal for your very first connection, and should not appear when you later connect to the same machine. If this happens, simply type yes and press Enter. This action will add the ssh key to the list of known hosts on your machine so that you don't see this warning again when you make future connections from the same machine. You can expect to see that warning again, however, if you connect from a
different computer.You will be prompted for your password. Enter your UT EID password and press Enter. Note that the password does not echo to the screen as you enter it.
You're done! You should now be connected to the LinCompute cluster.
