Modifying the arp cache was a clever trick. I wouldn't have thought of that.
(Now, of course, should this problem arise, i will gladly pull it out of my memory with a grin and a bored "well, that was obvious, wasn't it" to my colleagues ...) ;-)

I'm running an arp -an on a Solaris 10 box. We're using IPMP. One of the systems is not able to see a host on the same network. The only difference between the two systems (one is having a problem, the other isn't) at least so far is the output of arp:

Hello,
I have 2 clients with Unix installed.
host1: eth0 (192.168.5.10) & eth1 (192.168.10.10)

I've connected host1-eth1 to host2-eth0. host1-eth0 isn't connected.
I started 'tcpdump' on wonder that host2 got ARP requests for 192.168.5.10.
Any idea why host1... (2 Replies)
