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
[/var/log/messages]

this is my /etc/dhcpd.conf
# cat /etc/dhcpd.conf

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?
many thanks
Richard

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. ------------------------------------------------------------------------------------ [bepstein at dellnikon ~]$ more /etc/dhcpd.conf ddns-update-style interim; ignore client-updates; subnet 192.168.65.0 netmask 255.255.255.128 { # --- default gateway option routers 192.168.65.1; option subnet-mask 255.255.255.128; option nis-domain "nrims"; option domain-name "nrims"; option domain-name-servers 192.168.65.1,132.183.243.118,132.183.1.1 1; option time-offset -18000; # Eastern Standard Time # option ntp-servers 192.168.1.1; # option netbios-name-servers 192.168.1.1; # --- Selects point-to-point node (default is hybrid).
