Subject: SPARC 5 Dual NIC Problems
The port could show up and the cable can still be bad. When plugging into a
hub, you should use a standard Ethernet cable, not a cross over cable. My
second suggestion was to eliminate the hub for a test. Instead of plugging
into the hub, use a crossover cable and plug directly into a device that is
working on the 192.168.1.x network.

Second question since you stated that you were using a hub and a crossover
cable... Are you plugged into the uplink port of the hub? If you are, is
that port a shared port with its neighbor (some hubs have two ports that are
actually one port functioning as either an uplink port or standard port)?

The SPARC is going into a hub. When I plug in the cable to the hub the port
light comes on. When I have had a cross over cable problem in the past it
seems that the port light does not come on, so I am assuming that the cable
is working.

Did I miss something?

1. Is your SPARC plugged into a managed switch? If so, could it be that the
switch port is off or not setup with the proper untagged VLAN?

2. Have you tried using a crossover cable, directly plugging into a known
good machine, and pinging that good machine?

The route command gave the following output: 

Kernel IP routing table
Destination     Gateway      Genmask            Flags Metric Ref   Use Iface
192.168.1.0     0.0.0.0      255.255.255.0      U     0      0       0 eth0
10.0.0.0        0.0.0.0      255.0.0.0          U     0      0       0 eth1

What's the output of the "route" command? May be in /sbin so if you're
not root, it's not in your path, but you still can run it to list the
routes.
