Public bug reported:
My interface eth0 is configured like this:
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
qlen 1000
link/ether 00:1a:80:24:28:b8 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.34/24 brd 192.168.1.255 scope global eth0
inet6 fe80::21a:80ff:fe24:28b8/64 scope link
valid_lft forever preferred_lft forever
There's a local host 192.168.1.22 which is reachable:
$ ping -c1 -q 192.168.1.22
PING 192.168.1.22 (192.168.1.22) 56(84) bytes of data.
--- 192.168.1.22 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 5.476/5.476/5.476/0.000 ms
I can't ping this host with arping:
sudo arping -I eth0 192.168.1.22
ARPING 192.168.1.22 from 192.168.1.34 eth0
^CSent 8 probes (8 broadcast(s))
Received 0 response(s)
Running tpcdump shows that arping sends ARP discovery packets to wrong
MAC address (ff:1a:ff:24:00:b8) instead of broadcast
(ff:ff:ff:ff:ff:ff):
13:22:05.515156 ARP, Request who-has 192.168.1.22 (ff:1a:ff:24:00:b8) tell
192.168.1.34, length 28
13:22:06.515976 ARP, Request who-has 192.168.1.22 (ff:1a:ff:24:00:b8) tell
192.168.1.34, length 28
13:22:07.516058 ARP, Request who-has 192.168.1.22 (ff:1a:ff:24:00:b8) tell
192.168.1.34, length 28
Address ff:1a:ff:24:00:b8 looks familiar to my machines MAC
(00:1a:80:24:28:b8) - three octets match at correct positions. It seems
that arping somehow does incorrect discovery of broadcast address.
arping from lenny does not have this problem.
