Instead of aliases, you can put this into ~/. ssh/config: Host abcd Port 51023 Hostname 174.183.26.11 And then you can simply do this: ssh abcd As a bonus, the host abcd will work with scp and rsync too. You can check man ssh_config for some other options to use, for example the User is very useful too. Here are some more tricks: https://blog.flameeyes.eu/2011/01/mostly-unknown-openssh-tricks There is a package net-misc/keychain which is useful to add your keys to the agent, and handles gpg keys too. Also note that most ssh servers allow only 3-5 authentication attempts, so if you have more than 2 keys in your agent, then connecting to a server with password authentication might fail. If you need to keep security boundaries but don't want to give up the convenience of ssh agent forwarding then you can use ssh-ident, as described here: http://rabexc.org/posts/pitfalls-of-ssh-agents (unfortunately no gentoo package for that one, but it's just a single python file). Have a nice day, Paul
