Very useful. I'm currently using ~/.ssh/config. I gave nickname for the servers and all parameters are in the config:

  Host my-foo
  HostName 54.xx.xx.xx
  User my_user
  IdentityFile ~/.ssh/server_key.pem

So, just: ssh my-foo

Yeah that's what I do too. How is ssh2 any better? Especially considering (IIRC) that tab-complete works for ~/.ssh/config .

We're using a wrapper around SSH which generates an ssh_config file listing our current EC2 instances, including aliases for instance id, role, and name tags. It does slow down starting SSH if you don't have the list of instances cached, but otherwise is pretty nice.

Do you mind share your script? It seems very useful.

At the moment its a horrible hack which is so specific to our environment I'm not sure I want to share it, but I might make something more generic and share that.

I was about to post the same.

~/.ssh/config with identity files (certs) is the right way to ssh.

And ssh config entries can be used in other software, for example I use them in mc.
