Subject: Re: [PacketFence-users] Registration VLAN DHCP not working
Hello Eric,
Do you have the pfdhcp pfdhcplistener services running ?
What is the output of the command:
netstat -nlp | grep 67
Does eth0.21 is configured has a registration interface ?
Thanks,
Ludovic Zammit

I need to help troubleshooting DHCP on my registration VLAN.
I used tcpdump to see if DHCP packets are making it to the packetfence server
and they are:

However, PacketFence isn’t offering an IP to the client.
Here is my networks.conf file (I used the WebUI to configure the networks):

If I statically set an IP to the client (10.0.21.101/24), I can ping the client
from PacketFence and the client can ping PacketFence. Any idea what I am
missing?
