yeap, but I have a nice .ssh/config that does wildcard masking , and a few other things to make sure I can log into servers without remembering which SSH Key I need to use, and what username. e.g. I use the following snippet for my dev build boxes - they are rebuilt all the time, but I need to login and check system state from time to time. Host 10.250.60.* UserKnownHostsFile /dev/null StrictHostKeyChecking no IdentityFile ~/.ssh/local-dev-key User build If you are implementing multiple SSH Keys, remember that a -lot- few people will have keys on GPG Cards, YubiKeys and other devices, not just on disk.
