I am a debian newbie...trying to add a second NIC to my machine - one with
an internal and one with an external IP.
Linux registers both NICs, because this appears in /var/log/messages:
Sep 29 19:12:13 jacktasty kernel: eth0: 3Com 3c905B Cyclone 100baseTx at
0x1400, 00:10:5a:07:29:54, IRQ 10
Sep 29 19:12:13 jacktasty kernel: eth1: 3Com 3cSOHO100-TX Hurricane at
0x1480, 00:50:04:6d:36:ef, IRQ 9
So that's good. eth0 is working now as my external IP. next, i tried to
manually use ifconfig assing the internal IP to eth1 with this:
# ifconfig eth1 192.168.0.1 netmask 255.255.255.0
that worked, becaue when i issued an ifconfig command, it returned:
eth0 Link encap:Ethernet HWaddr 00:10:5A:07:29:54

all appears well, but when I try to ping a local machine, I get this:
PING 192.168.0.2 (192.168.0.2): 56 data bytes
ping: sendto: Operation not permitted
ping: wrote 192.168.0.2 64 chars, ret=-1
ping: sendto: Operation not permitted
ping: wrote 192.168.0.2 64 chars, ret=-1
ping: sendto: Operation not permitted
and I can't ping my debian box from my other local machine either. I
noticed in my /var/log/messages I had a bunch of these messages:
Sep 29 20:22:36 jacktasty kernel: Packet log: output DENY eth1 PROTO=1
192.168.0.1:8 192.168.0.2:0 L=84 S=0x00 I=3784 F=0x0000 T=64 (#4)

192.168.0.1:8 192.168.0.2:0 L=84 S=0x00 I=3786 F=0x0000 T=64 (#4)
am i missing some steps or doing something wrong?
Thanks,
rory
