I'm still setting up a Linux (2.0.36; Debian main/stable/slink 2.1)
server with 2 NICs: eth0 to a cable modem, and eth1 to my LAN
(NeXTstation and print server).

I've been having trouble with a 3C900-combo NIC as eth1.  I can ping the
card but not the LAN:

125 www% ping 192.168.4.1
PING 192.168.4.1 (192.168.4.1): 56 data bytes
64 bytes from 192.168.4.1: icmp_seq=0 ttl=64 time=0.6 ms
64 bytes from 192.168.4.1: icmp_seq=1 ttl=64 time=2.2 ms
64 bytes from 192.168.4.1: icmp_seq=2 ttl=64 time=2.1 ms

126 www% ping jetdirect 
PING jetdirect (192.168.4.2): 56 data bytes
ping: sendto: Operation not permitted

127 www% ping hygeia 
PING hygeia (192.168.4.3): 56 data bytes
ping: sendto: Operation not permitted
ping: wrote hygeia 64 chars, ret=-1
ping: sendto: Operation not permitted

Monitoring this in another window:

128 www# tcpdump -i eth1
tcpdump: listening on eth1
13:22:28.103961 arp who-has jetdirect tell www.abl.com
13:22:28.113961 arp reply jetdirect is-at 8:0:9:1f:7c:8
13:22:54.533961 arp who-has hygeia tell www.abl.com
13:22:54.533961 arp reply hygeia is-at 0:0:f:0:70:5c


So the network can find MAC addresses but not much else....

Any suggestions on what else to try?  (A different kernel?  Driver
update?)

Thanks for any help!
