Re: [Linux-cluster] ssh'ing to Cluster IP aliases.



You work fast, Actually Leo was on to something. My personal user ssh files where the same because of our automounted directories. However, I copied over the files in /etc/ssh to all three nodes in my cluster and ssh works great.(I can ssh from any node on our network to the VIP
addresses then fail the services over to the backup node and all is good)

I guess the problem with that is that the level of security is reduced a little.

I am going to try your way now and see how things work out.

I'm writing step by step wiki article now. ;)

[Note: it will need to be expanded for non-Red Hat/Fedora distributions]

Here's how to do it so that each service has a different ssh key (which
can be different from the host's ssh keys):

http://sources.redhat.com/cluster/wiki/ClusterSSH

This is designed to ensure that each {key, IP} pairing is static so that
connecting to a host (or a cluster IP) will not cause ssh to complain -
because each IP has a different SSH key.

Comments welcome.
