Environment
Situation
When testing a GroupWise Disaster Recovery (GWDR) collector profile, trying to connect up to
the paired GWDR server, the SSH key fails with the following error:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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
08:50:e8:e4:1b:17:fd:69:08:bf:44:f2:c4:e4:8a:27.
Please contact your system
administrator.
Add correct host key in
/root/.ssh/known_hosts to get rid of this message.
Offending key in
/root/.ssh/known_hosts:1
RSA host key for 1.1.1.2 has
changed and you have requested strict checking.
Host key verification failed.
Resolution
This error indicates that a key is already on the remote server using the same host name
or ipaddress for that key. This can happen if the GroupWise server, or GWDR Server was rebuilt or moved and is using
the same ipaddress or host name as before.
To fix this recreate the key. In a terminal prompt type the following command:
Where the host name or ipaddress is the destination server that is trying to connect (GWDR paired server)
This command is also useful to quickly reset any of the SSH keys and reestablish the SSH connection.
After this is done, attempt to connect to the ssh again (ssh hostname/ipaddress) or go back through the connectivity setting for the profile and run a test. It should be able to connect to the paired server without any problem.
