Add --fix-up-the-mess to fix up Offending key warnings for the user in one quick step!

[jidanni]

We are all familiar with the old routine,

$ ssh ...
Warning: the ECDSA host key for 'ssh.example.org' differs from the key for the IP address '164.190.144.253'
Offending key for IP in /home/jidanni/.ssh/known_hosts:20
Matching host key in /home/jidanni/.ssh/known_hosts:30

$ ed  /home/jidanni/.ssh/known_hosts
11098
20d
w
10656
q

$ ssh ...
Warning: Permanently added the ECDSA host key for IP address '64.90.44.253' to the list of known hosts.

Well I have a new idea!

At the end of the initial warning just add
"... or if you are really sure, just use --fix-up-the-mess to fix up the mess"
and then all the user would need to do is one
$ ssh --fix-up-the-mess ...
and voila, the mess is all fixed up! Even no one-time "Permanently added..." message!

(Of course please choose a better name than --fix-up-the-mess.) Thanks!

Yes, I hope --fix-up-the-mess would:

1. do the ed(1) etc. editing step for the user.
2. do the second run or whatever to Permanently add that line.

Thanks!

You seem to be talking about the ssh tool (from openssh?) that isn't related to this project!

OK, created https://bugzilla.mindrot.org/show_bug.cgi?id=2983 .
