Problem

When you are trying to connect to any of the CSIL or LINUX machines via SSH, you get:

ssh: connect to host csil.cs.ucsb.edu port 22: Connection refused

or

ssh: connect to host linux.engr.ucsb.edu port 22: Connection refused

Cause

It is possible that the IP your computer is connecting from is blocked by the computer's firewall for a period of time due to numerous failed attempts to log in.

Solution

The block will release after a period of time to allow access.

Please try and connect at another time.

While you are waiting to be allowed access, please make sure your username and/or password is correct by going here:
