When i try to Login the HPUX box by ssh, I am getting error such as. Please help me sort-out the problem.
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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
11:3c:82:2d:7b:ae:bf:62:9a:82:f4:13:02:07:37:b9.
Please contact your system administrator.
Add correct host key in /home/username/.ssh/known_hosts to get rid of this message.
Offending key in /home/username/.ssh/known_hosts:215
RSA host key for al2c69 has changed and you have requested strict checking.
Host key verification failed.
Thanks & Regards,

Re: Login Problem the HPUX
On the host you're ssh'ing from, edit the indicated known_hosts file. The offending line is on line 215. Delete that line. The ssh should work for you after you say yes to adding the new line to the known_hosts file.

Re: Login Problem the HPUX
If you have a lot of "known hosts" edit the known_hosts file and remove the offending key and try 'ssh' again.

SolutionWas there an ip address change for "al2c69". If this was a valid change, you can delete the old entry for "al2c69" in your known_hosts file and then retry.
Try,
sed -i 215d ~/.ssh/known_hosts
then ssh again to al2c69 and try.
Hope this helps.
Regards

Re: Login Problem the HPUX
This error is something that depends on your situation..
If your server is exposed to the world I'd think it might not hurt to do some intrusion forensics..
But if this server is in a secure environment, generally this error occurs as the result of changes to one of the systems that is connecting..
al2c69 likely has had the SSH client reloaded or the IP address of this box has changed.
as others have mentioned the simple fix is to remove the entry from the known_hosts file, which will resolve it.
When you log in again a new SSH/RSA key exchange will occur and the error will be fixed.

Re: Login Problem the HPUX
Commenet the line no 215 in the file
/home/username/.ssh/known_hosts and try again.
Before that one question. Was it working earlier or did you try to upgrade the system recently ?
