ssh questions

[azlobo73]

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.
