CS Dept SSH Frequently Asked Questions

1. I followed the directions and it didn't work. What should I do?

   Check the following:

   • Did you cut & paste the public entry when you copied it into ~/.ssh/authorized_keys? Each entry in that file must be on a single line. Delete any extra newlines and try again.

   • If your remote machine is a unix or linux machine:
     • The private key must be in a file named id_rsa, or else you must tell ssh where it is.

2. Can I use ssh1 to connect to the department?

   No, ssh1 has been disabled. Please use ssh2.

3. Can I use ssh2 to connect to the department?

   Yes, in fact ssh1 is no longer supported.

4. How do I transfer files to/from the department using ssh?

   Use scp. Rsync and cvs also know how to use an ssh connection to transfer files. There are probably other choices, too.

5. What machine(s) should/can I connect to?

   The only machine you can connect to from outside the department is ssh.cs.brown.edu. This machine is a dedicated portal to reach into the department via ssh.
