I hadn’t used a ~/.ssh/config since I’m such a curmudgeon. However, as I’m managing hosts on more and diverse networks from a single machine, I needed a way to make everything gel.
- The first of these networks require kerberized logins. There’s a fallback password prompt, but I always want to make use of my TGT. This Kerberos Identity is also not my default identity.
- The second network uses key-based authentication. To prevent this from conflicting with my default key, I set the key to be used. The saves me from having to use an -i flag.
- I also have a machine in EC2 that has a different key.
Host <alias> hostname <host.domain.tld> user <username> GSSAPIClientIdentity <username@DOMAIN.TLD> PasswordAuthentication no Host <alias> hostname <host.domain.tld> IdentityFile ~/.ssh/<id_file> port <port number> Host <alias> hostname <host.domain.tld> user <username> IdentityFile ~/.ssh/<other_id_file>
Now when I go to ssh, I just type
and I’m in. No more flags!
