Sorry for reviving this old post but I'm having trouble with the above
setup.
Everytime one of my slaves changes it's IP the hostfile on the ssh-
gateway gets updated. So for, so good. But the update just adds an
entry to the hosts-file, thereby leaving the old entry intact. So I
end up with:
10.72.1.21 server1
10.72.1.45 server1
10.72.1.90 server1
etc.
Is there an easy solution to this?
Thanks!
