Sorry about the delay, i've been busy with a few things. Anyway heres the info:
eth0 Link encap:Ethernet HWaddr 00:00:E8:8B:7E:66 inet addr:192.168.3.200 Bcast:192.168.3.255 Mask:255.255.252.0
OKish.
eth1 Link encap:Ethernet HWaddr 00:90:27:73:DB:FC inet addr:10.0.40.2 Bcast:10.0.41.255 Mask:255.255.254.0
OK. Who chose these subnet masks, btw?
PING 192.168.3.200 (192.168.3.200) from 192.168.3.200 : 56(84) bytes of data. 64 bytes from 192.168.3.200: icmp_seq=1 ttl=255 time=0.180 ms
Proves that eth0 interface is working, but proves nothing about routing to 192.168.0.0/255.255.252.0 network.
PING 192.168.3.201 (192.168.3.201) from 192.168.3.200 : 56(84) bytes of data. From 192.168.3.200: icmp_seq=1 Destination Host Unreachable
Suggests a dead host. A routing problem would show up as "connect: Network is unreachable"
PING 10.0.40.2 (10.0.40.2) from 10.0.40.2 : 56(84) bytes of data. 64 bytes from 10.0.40.2: icmp_seq=1 ttl=255 time=0.137 ms
Again, proves that eth1 is working but doesn't say anything about state of routing to 10.0.40.0/255.255.254.0
PING 10.0.40.1 (10.0.40.1) from 10.0.40.2 : 56(84) bytes of data. From 10.0.40.2: icmp_seq=1 Destination Host Unreachable
Suggests a dead host, as before.

Routing looks OK, assuming that 10.0.40.1 is the IP address of your default gateway. Are you *sure* that you have the physical network cables plugged in the right way round (as in eth0->192.168.0.0 network, eth1->10.0.40.0 network)? Are you also sure that the hosts you are pinging (192.168.3.201 and 10.0.40.1) are alive and able to communicate with the rest of the network? You could try running tcpdump -i eth0 -n and tcpdump -i eth1 -n to observe traffic coming to both network cards. This should show you if you have got the wires mixed up. As a final check: do you have any firewalling (ipchains/iptables) rules set up? Michael Brown http://www.fensystems.co.uk -- Fen Systems: Linux made easy for schools
