SSH Key for MAC M1

ssh-key-setup-mac.md

1. ssh-keygen -t rsa -b 4096 -C "ubelix" and decide path and passphrase.
2. Add to ~/.ssh/config:

   Host ubelix
    UseKeychain yes
    AddKeysToAgent yes
    IdentityFile ~/.ssh/id_rsa_ubelix
    Hostname submit03.unibe.ch
    User <YOUR_USER_HERE>
    ServerAliveInterval 60
   

3. ssh-copy-id -i ~/.ssh/id_rsa_ubelix.pub ubelix.
4. ssh-add --apple-use-keychain ~/.ssh/id_rsa_ubelix for Monterey OS.
5. ssh ubelix. If you have issue with password prompting, verify home directory permissions (it might be useful to run ssh in verbose mode).
