how to add private options in dhcpd.conf
 

I have a problem when I config my dhcpd configfile.

The function I need is dhcpd will send the dhcp offer packet with a special option that it include an ipaddr.

so I modify the /etc/dhcp3/dhcpd.conf as below:

/************************************************
option enc-server code 200 = ip-address;
option enc-server 192.168.70.59;
**************************************************/

but it cannot work. so can someone help me to work it out? Thanks!

What happens if you use the option in your actual subnet declaration?

i.e.

subnet 192.168.70.0 netmask 255.255.255.0 {
...
option enc-server 192.168.70.59;
...
}

Also, have you tried using tcpdump to see if you are actually getting the option and your application is just not handling it correctly?

I tired, but it didnot work, i cannot find option 224 in packets which snap by wireshark .
