Hi all,
I have troubles getting proxy ARP to run on newer kernels (2.4.0-test8,
for example). I tried to run
# arp -s 1.2.3.4 01:02:03:04:05:06 pub
(where 1.2.3.4 is an IP address on a local network and 01:02:03:04:05:06 is
a HW address of my machine). I tried to ping 1.2.3.4 from another host
on the same network, but this host did not get ARP reply (as seen by tcpdump
both on the proxy ARP host and on the ping host -- there were only arp
requests, but no replies). I tried to do
echo 1 >/proc/sys/net/ipv4/conf/eth0/proxy_arp
but it did not help. The arp entry seems strange, though. In my /proc/net/arp
there is the following line:
1.2.3.40x1 0xc 00:00:00:00:00:00 * eth0
^^^
Note that on marked place there is no whitespace (on regular
arp entries there is a whitespace between the IP address and HW type).
Note also zeros instead of my HW address. The same occurs when I try
to use
# ip neigh add proxy 1.2.3.4 dev eth0
Are there any problems with proxy arp on 2.4 pre kernels?
