How do I setup SSH/SCP/SFTP access to a Cluster server VIP Address?
Issue
- I need to access SSH/SCP/SFTP via my cluster's VIP (Floating IP).
- My cluster has a SSH/SCP/SFTP service.
- I already have the SSH/SCP/SFTP service running on all the cluster nodes, but when I try to connect to the IP of a node or the cluster's VIP I get a message like this:
[someuser@localhost] $ ssh someuser@www.xxx.yyy.zzz

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
XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX.
Please contact your system administrator.
Add correct host key in /home/someuser/.ssh/known_hosts to get rid of this message.
Offending key in /home/someuser/.ssh/known_hosts:#line-number
RSA host key for www.xxx.yyy.zzz has changed and you have requested strict checking.
Host key verification failed.
