Hi all,
this is my first post on this list, hope someone can help me.
I have to run a dhcp server on CentOS release 5.5 (Final).
# yum list| grep -i dhcp dhcp.x86_64 12:3.0.5-23.el5 installed dhcp-devel.x86_64 12:3.0.5-23.el5 installed dhcpv6-client.x86_64 1.0.10-18.el5 installed
after starting the dhcpd daemon, the windows Clients on the subnet (192.168.100.0/24) tells me, that there is no dhcp server available.
# /etc/init.d/dhcpd configtest Syntax: OK

this is my /etc/dhcpd.conf
# cat /etc/dhcpd.conf authoritative; ddns-update-style interim; subnet 192.168.100.0 netmask 255.255.255.0 { option routers 192.168.100.11; option subnet-mask 255.255.255.0;
option domain-name "<mydomain>.local"; option domain-name-servers 192.168.100.2;
option time-offset -18000; # Eastern Standard Time
range 192.168.100.150 192.168.100.199; }
what do I'm missing? or is there a config mismatch?

Richard,
I don't have time to go through that config line by line but here is mine that works. It is not perfect, has some unnecessary stuff in it, the domain used is a private domain but like I said it works so it must have at least as much as necessary to make it work.
