[Dnsmasq-discuss] dnsmasq.conf 2.41 violates RFC-2132 ondhcp-option=47

[Data Control Systems - Mike Elkevizth]

I have checked /var/log/messages on both the dnsmasq server (which is CentOS
4.7) and the client (OpenSUSE 11.0).  The server shows that it is sending a
DHCPOFFER and DHCPACK after a DHCPREQUEST from the client.  The client
rarely (like I said it is intermittent) shows a DHCPINFORM.  I might check
the wire with Wireshark, but since it is only one client that has the
problem, it was much easier to just assign a static IP and hope that the
problem gets fixed sometime in the future.

Thanks for the advise,

Mike

Check /var/log/messages and see why it refuses the address, or check with
tshark/tcpdump what happens on the wire.
