Greetings all,
[ Quick summary, in the logs I am getting the following type of 'errors': ]
[ Mar 22 19:32:51 libra kernel: nf_hook: hook 3 already set. ]
[ Mar 22 19:32:51 libra kernel: skb: pf=7 (owned) dev=eth1 len=96 ]
[ Mar 22 19:36:24 libra kernel: nf_hook: hook 3 already set. ]
[ Mar 22 19:36:24 libra kernel: skb: pf=7 (unowned) dev=eth2 len=136 ]
*** Why am I getting the these messages?
Firstly, I have a bridge (br0) between two eepro100 cards (eth1, eth2)
which seems to be working perfectly without an assigned IP address.
I have a third interface (eth0) which I'm using to configure the box.
[ 192.168.20.2 ] --- [ eth1 | br0 | eth2 ] --- [192.168.20.4]
The problem occurs when I try to add an IP address to br0.
[Using linux 2.4.17 with no additional patches.]
When brought up with 'ifconfig br0 0.0.0.0' everything works well.

TX packets:982 errors:0 dropped:0 overruns:0 carrier:0

The problem comes when I add an ipaddress, with:
ifconfig br0 192.168.20.1 netmask 255.255.255.0 broadcast 192.168.20.255
If I try to transmit.. eg. ping 192.168.20.2
I get the following on the console..
nf_hook: hook 3 already set.
skb: pf=7 (owned) dev=eth2 len=84
nf_hook: hook 4 already set.
skb: pf=7 (owned) dev=eth2 len=84

Ping results from the bridge:
# ping 192.168.20.2 -c 1
PING 192.168.20.2 (192.168.20.2): 56 data bytes
64 bytes from 192.168.20.2: icmp_seq=0 ttl=255 time=109.3 ms
(Should it really take this long?)
Ping result through the bridge:
# ping 192.168.20.2 -c 1
PING 192.168.20.2 (192.168.20.2): 56 data bytes
64 bytes from 192.168.20.2: icmp_seq=0 ttl=255 time=0.2 ms
There are no messages when using eth0.
Any ideas? Thanks in advance.
Paul
