Subject: DHCP 1.3 Beta does not work on FreeBSD 2.1

I recently got the port (FreeBSD-current/ports/net/dhcp) and source
(ftp://sh.wide.ad.jp/WIDE/free-ware/dhcp/dhcp-1.3beta.tar.gz) and it compiled
successfully on a FreeBSD 2.1. However, my Win95 (DHCP client) and
Lan Workplace (BOOTP client) cannot work with the WIDE DHCP 1.3 server.

Tcpdump showed the conversation as

09:15:33.454481 0.0.0.0.bootpc > 255.255.255.255.bootps: xid:0x5b025b02 [lbootp]

                0000

My server 172.22.20.3 (0:0:f8:e0:bb) tried to give the address 172.22.21.108
to the client (0:0:f8:1:17:7). It seems to me that even tcpdump could not
decode the BOOTREPLY message.

Do you have any clue on how to make it work? Thanks very much.

Yes, same problem.

After 2 days i've reached my goal, and it works in my school.
I've tried the same at home, but without success. The DHCP server
doesnt want to do a correct reply to DHCP-request from W95.
I cant figure out, what it is.
After disabling DHCP, i started bootpd, which sends correct
replies. But W95 ignores the incoming messages from bootpd.

Today i'll get my car and drive into this school. I hope to find there the
bug in the evening and kill it tonight at home.

Lars.

PS: You must DISABLE DNS in W95-networksetup, if you want to use DHCP !!!
    strange, but true.

I got a reply from WIDE indicating that the FreeBSD-current port of DHCP has
bugs and there is an unofficial port from ftp.phys.keio.ac.jp. I tried that
and it works with Win95 (DHCP client) and Lan WorkPlace (BOOTP client).

  I re-ported WIDE DHCP to FreeBSD 2.1R. I put it to:

ftp://ftp.phys.keio.ac.jp/pub/FreeBSD/unofficial-ports/dhcp-1.3.tar.gz

Both reply, but if the novell box is NOT running bootpd, there is not
a valid reply sent to the client...

I'm going to try the other port... (fingers crossed!)
