Hello,
I tried posting under a similar topic, but not sure if it went through. I'm new on this list, but not a total newbie. I have upgraded a system from p6 to p7. Everything seems to be working on wtih the upgraded system except for dhcp.
I have a backup of the old system and am using that to trouble shoot. I have narrowed it down to the dhcpd binary. If I put in the newer binary built with p7 it does not work with windows 2000. If I put in the old binary it works fine.
Old Binary ( tcpdump ):
IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 00:19:d1:df:f3:07,
length: 317
IP sss.sss.sss.sss.67 > ppp.ppp.ppp.ppp.68: BOOTP/DHCP, Reply, length: 300
New Binary ( tcpdump ):
[ windows 2000 ] :

No reply is ever sent out

FreeBSD clients seem to be able to obtain a new address with no problem.
My question is how do I trouble shoot the two binaries? What tools can I use? How do I get dhcpd to actually put out debugging info to the syslogs or on the command line? I've tried the -d and got nothing.
any help is much appreciated.
Thanks,
Joe
