Hi, When I try to ssh in the fc3 from another server,

When do I need to start up?

Is "fc3-server" in your /etc/hosts file or
resolvable via DNS?  Can
you ping it?  Do you have a default gateway
configured that can get at
it?

You didn't say if you can ping it by name or IP only.  We need to know
that.

fc3-server is not in the S1's /etc/hosts.

If pinging via the IP address works, but pinging via the hostname doesn't, you either need to enter the IP and hostname into /etc/hosts or
make sure there are appropriate records in your DNS service.

How do I check whether fc3-server is resolvable via
DNS, and also the gateway?

To check DNS, "# dig fc3-server".  See if you get an address back.

Since you can ping it one way or the other, the gateway is probably OK.
