Hello,
I have run through all the trouble shooting stuff in The Complete
FreeBSD book and searched around on the net for a solution to my
problem, but I could not find anything so I am turning to the list.
I have set up a FreeBSD 3.4 machine on my LAN and have run into a
strange problem where the FreeBSD machine (toothgnasher) does not
want to reply to arp requests from any of my other machines on the
network. If I re-ifconfig the adapter, I will be able to ping the
FreeBSD box from the other machines, but if there is no network
traffic between the machines then it will stop working after a few
minutes. I can always ping from the FreeBSD machine but not to it.
Here is the result of running ping from my win98 machine (musicalgoat):
C:\WINDOWS>ping 10.0.0.2
Request timed out.
Request timed out.
...
Here is what my OpenBSD (parakeet) box says for tcpdump -i pn1 arp:
03:44:33.867772 arp who-has toothgnasher tell musicalgoat.parakeet.nailed.org
... (a bunch of these)
03:45:29.305128 arp who-has toothgnasher tell musicalgoat.parakeet.nailed.org
(now I run ifconfig mx0 inet 10.0.0.2 netmask 0xffffff00 on FreeBSD box)
03:45:29.986575 arp who-has toothgnasher tell toothgnasher

Once I get the machine to reply to the arp request everything goes fine
but only for a few minutes. Anybody run into this problem before?
Thank you,
