I've just set up a second vps (s2.example.com) and when trying to restart SSH I'm getting the following error:
"The authenticity of host 'restart (xxx.xxx.xxx.74)' can't be established."
The IP address (ending .74) is not the IP address of that server. It is the IP address of another vps running at www.example.com.
I've set an A record for s2 to point to the correct IP address for that server.
Any ideas what I'm doing wrong?
