Hi all - new to the list, so easy on me ;o)
Does anyone have any experience of running SSH of any kind on clustern
systems such as
SUNCluster 2.2 or HP Serviceguard?
The problem I have been asked about is a SUNCluster, and basically ssh runs
fine on the
logical host of the cluster until failover, whereupon the host key changes
and SSH thinks
it's under attack. Logic tells me therefore that the SSH running on the
logical host is using
the host key of the physical host that the logical host happens to be on at
startup.
Logic further tells me that there are some ways that *might* be tried to fix
this, with their advantages
and disadvantages
1) Have a install of ssh software just for the logical host which resides
completely on the shared
storage of the cluster (so that the same host key is always available)
2) have the same host keys on both nodes of the cluster (!)
Does anyone have any experience of SSH on commercial clustering software and
if so, is there a
"proper" solution? If not, will *my* solutions above work?
I ask this because someone's trying to get SSH up on this one cluster, but I
have just been
given a project to roll out SSH to the entire enterprise's secured intranet,
on which there are lots
of clusters of various types...
Thanks for your help.
