Using Linux as a DHCP server 2

[columb]

I have a class c subnet - 137.223.168.0/24
The gateway is 137.223.168.1
Various servers have fixed addresses for 137.223.168.2, 137.223.168.3, 137.223.168.4 and 137.223.168.5
The 137.223.168.4 server is a RedHat Linux box.
I've created a dhcp.conf file which looks like

#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
ddns-update-style interim;
ignore client-updates;

subnet 137.223.168.0 netmask 255.255.255.0 {
        option routers                  137.223.168.1;
        option subnet-mask              255.255.255.0;
        range dynamic-bootp 137.223.168.6 137.223.168.254;
        default-lease-time 21600;
        max-lease-time 43200;
}

However, when I try to start DHCP I get

[root@bnls681u etc]# service dhcpd start

Have you checked the obvious? i.e. dhcpd already running?

Annihilannic.

 

[columb]

Yes, there's no dhcp or bootp processes running.

Did you verify

and that there's no entry for dhcp or bootp in /etc/inetd.conf
[\code]

Can you plese post the output of 
"lsof -Pni" 
if you still believe something is wrong....?

As I don't seem to have an inetd.conf where else should I be looking?
I've tried

[root@bnls681u etc]# grep dhcp *
dhcpd.conf:#   see /usr/share/doc/dhcp*/dhcpd.conf.sample

When a machine boots up, if it's using DHCP it broadcasts to find the DHCP server, which responds giving IP and DNS info. Surely, you can only have one machine serving up DHCP leases on a network?

Perhaps it's not your box that is the problem - is another box on your network already running a DHCP service?

It appears that homeagent is already running a dhcp server for you:

homeagent 3279 root 13u IPv4 8569 UDP *:67
