Hi, Here is the output of 'ifconfig' that I am running (the real ip's have been obfuscated) on my gateway (2.2.20pre9) : eth0 Link encap:Ethernet HWaddr 00:20:78:05:EA:0B inet addr:192.168.10.140 Bcast:192.168.10.191 Mask:255.255.255.192 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:60154532 errors:2 dropped:472 overruns:2 frame:2 TX packets:62565527 errors:1 dropped:0 overruns:1 carrier:0 collisions:0 txqueuelen:100 Interrupt:15 Base address:0xa000 eth1 Link encap:Ethernet HWaddr 00:03:6D:1C:E3:3F inet addr:192.168.9.1 Bcast:192.168.9.31 Mask:255.255.255.224 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:51351501 errors:2 dropped:5 overruns:2 frame:2 TX packets:50714444 errors:2 dropped:0 overruns:2 carrier:0 collisions:0 txqueuelen:100 Interrupt:5 Base address:0x9000 eth1:0 Link encap:Ethernet HWaddr 00:03:6D:1C:E3:3F inet addr:192.168.9.2 Bcast:192.168.9.31 Mask:255.255.255.224 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:5 Base address:0x9000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:3924 Metric:1 RX packets:1639 errors:0 dropped:0 overruns:0 frame:0 TX packets:1639 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 tr0 Link encap:16/4 Mbps Token Ring HWaddr 00:20:35:86:65:5A inet addr:192.168.8.1 Bcast:192.168.8.31 Mask:255.255.255.224 UP BROADCAST RUNNING PROMISC MULTICAST MTU:2000 Metric:1 RX packets:42078661 errors:0 dropped:0 overruns:0 frame:0 TX packets:24478956 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 Interrupt:9 Base address:0x9100 And here is the result of 'route -vn' : Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.9.0 0.0.0.0 255.255.255.224 U 0 0 0 eth1 192.168.8.0 0.0.0.0 255.255.255.224 U 0 0 0 tr0 192.168.10.128 0.0.0.0 255.255.255.192 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 0.0.0.0 9.3.54.129 0.0.0.0 UG 0 0 0 eth0 ip_forwarding is enabled and no firewalling is done. Here is the odd part : if I ping 192.168.9.15, tcpdump shows me the echo request and echo reply correctly. However, if I ping 192.168.9.16, the packets are seen on the lo0 interface instead of the eth1 interface - as they should be. Its almost as if the machine thinks that 192.168.9.16 is a local ip address. Yes the interface errors on eth0 and eth1 are a matter of concern, but I didnt think they have anything to do with this problem. Chances are that I have cabling problems, and am investigating that too. For reference, here are the boot messages that have to do with the cards in question : Olympic.c v0.4.0 3/10/00 - Peter De Schrijver & Mike Phillips tr0: IBM PCI tokenring card. I/O at 9100, MMIO at c4802000, LAP at c4804000, using irq 9 tulip.c:v0.91g-ppc 7/16/99 becker@cesdis.gsfc.nasa.gov eth0: ADMtek Centaur-P rev 17 at 0xa000, 00:20:78:05:EA:0B, IRQ 15. eth1: ADMtek Centaur-P rev 17 at 0x9000, 00:03:6D:1C:E3:3F, IRQ 5. Any ideas on why I am having this problem?
