I have been getting these errors to the system log file:

Unusual System Events
Jun 16 11:04:42 myhostname dhcpd: DHCPREQUEST for
from xx:xx:xx:xx:xx:xx via eth1
Jun 16 11:04:42 myhostname dhcpd: DHCPACK on to
xx:xx:xx:xx:xx:xx via eth1


It coresponds to this destination unreachable error showing up in trafshow.

beta is my internal nics hostname

udp netbio beta.crew321 netbio 2688
icmp beta.crew321 destun 3472

but DNS is working. if I winipcfg on clients and release / renew it works, and the leases file is working.

Can I just get it to stop emailing me these bogus errors?

How can it think it is undelivered anyway?

Shouldn't the client be the one complaining.


I only really know what I know I know, not what I think I know, I think.

The events generated are normal for the dhcp server with teh default logging. If you are getting destiantion unreachable erros is it because your firewall is blocking UDP netbios (137/138/139) packets?

ok thinks

I guess I need to open the ports to my internetwork by

-A input -s 0/0 -d -p udp -i eth1 -j ACCEPT

I will try it out.
