A ssh server on 192.168.1.45 listens on port 2222. I know I can just add -p2222 or add an alias in ~/.bash_aliases, but is there a way to force a certain port when I ssh a specified IP?
Sure, you can put these settings in ~/.ssh/config.
Host 192.168.1.45
Port 2222
You can take this opportunity to give the machine a nickname, and set other options, in particular the remote user name. For example, the following declaration makes ssh foo equivalent to ssh -p 2222 [email protected] (Host foo means that the following options apply when you run ssh foo, and the HostName directive makes foo a nickname for 192.168.1.45 with all the other options):
Host foo
HostName 192.168.1.45
Port 2222
