[Bug 424053] [NEW] Clarify the offending known_hosts line number when ssh key has changed

[Scott Ritchie]

Public bug reported:

I came across this error when I updated one of my servers.

Add correct host key in /home/scott/.ssh/known_hosts to get rid of this message.
Offending key in /home/scott/.ssh/known_hosts:2
RSA host key for (server) has changed and you have requested strict checking.

This was completely expected, as I had just updated the server, however
when I edited known_hosts I wasn't sure which key it was.  There was no
text description of the server names in that file.


Only later did I learn that the :2 above meant "on line 2".  What would have helped me greatly here is if the line:
"Offending key in /home/scott/.ssh/known_hosts:2" instead said
"Offending key in /home/scott/.ssh/known_hosts on line 2"


Should be a simple change, but for me it would have saved a good half hour while I looked up man pages trying to find the nonexistent "reask for the key when I connect to this one" setting.
