Re: Bad interaction of SO_BINDTODEVICE and ARP in Linux 2.4.10

[Joerg Pommnitz]

Hi Lists,
I worked around my previous problem by deleting the routing
entry that sent packets for my subnet directly to their
destination. Using our default router works (somewhat).

I can now see the ICMP packets on eth1:

jpo> /sbin/ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:E0:4C:71:05:92
          inet addr:10.1.12.87  Bcast:10.1.12.255  Mask:255.255.255.0
eth1      Link encap:Ethernet  HWaddr 00:E0:4C:71:05:91
          inet addr:10.1.12.151  Bcast:10.1.12.255  Mask:255.255.255.0
jpo> netstat -rn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt
Iface
0.0.0.0         10.1.12.1       0.0.0.0         UG       40 0          0
eth0

jpo> ping -I eth0 10.1.12.151
jpo> sudo /usr/sbin/tcpdump -i eth1 host 10.1.12.151 -n
tcpdump: listening on eth1
20:40:46.289402 10.1.12.87 > 10.1.12.151: icmp: echo request (DF)
20:40:47.289402 10.1.12.87 > 10.1.12.151: icmp: echo request (DF)
20:40:48.289402 10.1.12.87 > 10.1.12.151: icmp: echo request (DF)
20:40:49.289402 10.1.12.87 > 10.1.12.151: icmp: echo request (DF)
20:40:50.289402 10.1.12.87 > 10.1.12.151: icmp: echo request (DF)

It seems that no answer is sent at all. Any ideas?
