| Subject: | ARP responses |

Hi All,
I am trying to write a small program to implement proxy arp using libnet and
libpcap. So far I was able to write arp responses to the wire; but for some
reason, my host is not seeing those responses. But I was able to see those
packets on the wire using tcpdump though.
Here's what tcpdump shows me:
20:58:27.488240 0:10:a4:8b:9e:c9 ff:ff:ff:ff:ff:ff 0806 42: arp who-has
xx.xx.xx.xx tell xx.xx.xx.xx
0001 0800 0604 0001 0010 a48b 9ec9 xxxx
xxxx 0000 0000 0000 xxxx xxxx
20:58:27.488540 0:10:a4:8b:9e:c9 0:10:a4:8b:9e:c9 0806 60: arp reply
xx.xx.xx.xx is-at 0:10:a4:8b:9e:c9
0001 0800 0604 0002 0010 a48b 9ec9 xxxx
xxxx 0010 a48b 9ec9 xxxx xxxx 0000 0000
0000 0000 0000 0000 0000 0000 0000
This is how my arp cahce looks like
? (1.1.1.1) at 02:00:6D:2B:C7:E8 [ether] on eth0
? (2.2.2.2) at <incomplete> on eth0
Any advice is greatly appreciated.
Thanks
Mohan
