Hi Tina,
Thanks for sharing your experience. I found:
-F configfile
Specifies an alternative per-user configuration file. If a
configuration file is given on the command line, the system-wide
configuration file (/etc/ssh/ssh_config) will
be ignored. The default for the
Is that ssh conf dynamically generated to limit access only to nodes

However, this requires allowing users to SSH into compute nodes. In such
