Config file
Add to or create a new file on your laptop to add the login nodes and all hosts ~/.ssh/config
On Mac Terminal
scicomp@MAC2024 ~ % scicomp@MAC2024 ~ % cd .ssh scicomp@MAC2024 .ssh % ls (check what is listed below if there is anything) scicomp@MAC2024 .ssh % vim config
Editing your config file
Host cayuga-login1 Hostname cayuga-login1.cac.cornell.edu IdentityFile ~/.ssh/your_cayuga_key User your_cwid Host c00* IdentityFile ~/.ssh/your_cayuga_key User your_cwid ProxyCommand ssh -i .ssh/[your_key_name] -W %h:%p cayuga-login1
