SSH Config

Have you ever gone through the hassle of having multiple public/private keys for accessing your remote servers? Before recently, I used to specify the identity file in all my transactions ssh -I ~/.ssh/private_key user@host but no longer! I discovered you can add the following to your ~/.ssh/config to specify which key you want to use!

Host someaddress
    Hostname someaddress
    user usernameonserver
    IdentityFile ~/.ssh/private_key

Of course you can add multiple of these entries in that file so that you can ssh without having to worry about explicitly using keys.
