Good guess. :2 is line 2, :3 is line 3 The answer to the second might also help clear up the first (if you are connecting to the same machine using different names, or if you used to connect to a host/ip using one, but upgraded/changed the system (including host keys) then connect using another): .bashrc is sourced during non-interactive shell actions (scripts, crontabs, etc), while .bash_profile or .profile is source during interactive shells (logins, etc). If you set/use aliases or functions (can work like alias but can take args - $1 $2 $@ etc - in places middle of commands, not just append blindly at end of alias cmd line) to short-hand ssh host connections, you might check for 'triggerfish' or '192.168.2.124' and standardize on one.
