You can also set "StrictHostKeyChecking no" in /etc/ssh/ssh_config or
~/.ssh/config<br>
You'll still get a warning, but it wont refuse to let you in the box.<br>

Have you ever gone to ssh a host you'd rebuilt recently, and gotten one of these?
$ ssh smi-admin@10.0.1.2
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
7a:0b:f3:8a:52:e0:1a:e3:f6:26:b3:e8:31:a0:af:cf.
Please contact your system administrator.
Add correct host key in /home/dlwillson/.ssh/known_hosts to get rid of this message.
Offending key in /home/dlwillson/.ssh/known_hosts:95
RSA host key for 10.0.1.2 has changed and you have requested strict checking.
Host key verification failed.
Well, I get them all the time, and I found the easy way to delete the old key, but
quick. Notice that it gives you the line-number of the offending key, so you can use
the "</a>start at line" shortcut when starting vim to go straight to it when you edit your
known_hosts file. Like this:
dlwillson@aurora:~
$ vim +95 .ssh/known_hosts
Now, you just key in ddZZ (dd deletes the bad key, and ZZ saves and quits) and try your
ssh again.
