[Linux-cluster] Can telnet or ssh be a clustered service?

[Brad Filipek]

Since telnet runs as part of the xinetd service, that would mean that
all other included services in xinted would not function as well. Would
this cause any problems on the backup node since xinetd would be stopped
while the node waits to be turned active on a failover?

You can cluster any service you want.  However, clustering SSH would
have one problem that I can think of.  As the cluster failed from node
to node the SSH host key would change relative to the client.  This
would cause the SSH clients to report this change.  Any automated SSH
scripts could fail when this happens.
