the file is usually located at /etc/dhcpd.conf... if you don't have it and you're sure dhcpd is installed, try creating it and populating it with a googled example... it weird, though, cuz the file is usually created when you install the dhcpd package...

you'll also need a lease file, which unlike the conf file, is usually NOT there by default... to create the empty lease file do a:

Code:

touch /var/state/dhcp/dhcpd.leases

your state directory might vary depending on your distro... what distro are you using??

you can check if dhcpd is running like this:

Code:

ps aux | grep dhcpd

you can start it by using the command "dhcpd" followed by the interface you want it to listen on... for example:

Code:

dhcpd eth1

you have to create the dhcpd.conf file in /etc.
very simple example:

ddns-update-style ad-hoc;

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.5 192.168.1.10;
}

-thats it, create this file and then run 'service dhcpd start' and see if you get any errors, check your client ip address, you may have restart the network on the client so it'll pick up the new ip between 1 and 10.

Is there any sample configuration file like all other services

drhonez · 01-28-2005, 02:57 AM

what exactly do mean by 'all other services'?????????? there are config files all throughout /etc.

There is a sample dhcpd.conf file. I think its in /usr/share/doc/dhcp3xxxx/
Search for it, its definately there. Copy and edit it to suit your needs, its much easier.

here's a simple dhcpd.conf example, it's all pretty straight-forward:

Code:

ddns-update-style none;
subnet 192.168.0.0 netmask 255.255.255.0 {
        option routers 192.168.0.1;
        option subnet-mask 255.255.255.0;
        option domain-name "whatever.dom";
        option domain-name-servers 192.168.0.1;
        option broadcast-address 192.168.0.255;
        range 192.168.0.201 192.168.0.254;
        default-lease-time 43200;
        max-lease-time 86400;
        }

and if you'd wanna assign certain IPs to certain MAC addresses:

Code:

ddns-update-style none;
subnet 192.168.0.0 netmask 255.255.255.0 {
        option routers 192.168.0.1;
        option subnet-mask 255.255.255.0;
        option domain-name "whatever.dom";
        option domain-name-servers 192.168.0.1;
        option broadcast-address 192.168.0.255;
        range 192.168.0.201 192.168.0.254;
        default-lease-time 43200;
        max-lease-time 86400;

        host admin {
        hardware ethernet 0e:e0:09:06:55:69;
        fixed-address 192.168.0.100;
        option host-name "admin";
        }

        host dumbo {
        hardware ethernet 07:7c:76:5e:6e:78;
        fixed-address 192.168.0.101;
        option host-name "dumbo";
        }

        }
