I just tried this on:
2.0-BETA5 (i386) built on Thu Jan 13 20:30:46 EST 2011
and it doesn't seems to be sending the extra options defined:
192.168.0.1.67 > 255.255.255.255.68: [udp sum ok] BOOTP/DHCP, Reply, length 300, xid 0x295fdbd5, secs 1280, Flags [Broadcast] (0x8000)
Your-IP 192.168.0.7
Client-Ethernet-Address 00:26:****
Vendor-rfc1048 Extensions
Magic Cookie 0x63825363
DHCP-Message Option 53, length 1: Offer
Server-ID Option 54, length 4: 192.168.0.1
Lease-Time Option 51, length 4: 1800
Subnet-Mask Option 1, length 4: 255.255.255.0
Domain-Name Option 15, length 20: "******"
Default-Gateway Option 3, length 4: 192.168.0.1
Domain-Name-Server Option 6, length 4: 192.168.0.1
Although it's in /var/dhcpd/etc/dhcpd.conf:
…
option custom-lan-0 code 252 = string;
...
option custom-lan-0 "http://192.168.2.13:80/wpad.dat";
...
And i restarted dhcpd after config change.
I don't think this option was available in 1.* branch, has been a long time since i've used it though... So maybe this should be moved to the 2.0 board?
... it should be in the OFFER, right? Or is it only sent when requesting extra options in an INFORM?
