Since I'm not able to reply to the archived posts from earlier this
year when people were asking how to do this, here is a quick config for
anyone doing a websearch now or in the future. This is an example of how
to use a linux dhcpd DHCP server to hand out ip address leases and
specify the TFTP option 150 for VoIP phones in the dhcpd.conf config
file.
# /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
# Define Custom Options
option option-150 code 150 = ip-address;
# Global Config
option ip-forwarding off;
option nis-domain "domain.local";
option domain-name "domain.local";
default-lease-time 21600;
max-lease-time 43200;
subnet 192.168.117.0 netmask 255.255.255.0 {
option routers 192.168.0.1; #
Default Gateway
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option domain-name-servers 192.168.0.10;
option nntp-server 192.168.0.10;
option time-offset -18000; #
Eastern Standard Time
option option-150 192.168.200.10;
# TFTP Custom Option
next-server 192.168.200.10;
# TFTP Boot
range dynamic-bootp 192.168.0.200 192.168.0.249;
}
Enjoy.
