It gets only > "no connection". That routing table shows that dalton knows the route to joule. From the network diagram we see that dalton also knows the (connected) route to cantor via eth3 (aka eth1). Assuming no iptables blocks on any of the three systems, you still need to ensure: 1) That cantor knows the route to joule (via dalton) 2) That joule knows the route to cantor (via dalton) In short, every step along the way needs to know how to route packets in both directions. --Mike Bird -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
