Dear Ibrahim,
This error means that you haven’t configured the DHCP server.

sweet article, I usually watch youtube and take notes, but I cant watch youtube in class…lol
So far i have a DNS and APACHE server up, now time for the DHCP server all in VMworkstation..

To answers Javiers questions 192.168.1.0 is the network address that marks the beginning of the addresses for that subnet. So 255.255.255.0 = /24 , so you can only have 254 addresses avaliable.

Nice article, and very usufull. but i have a inocent dude……
would be the configuration for the gateway as 192.168.1.1 and the domain name server 192.168.1.253 and 192.168.1.254…..
And another question above. ¿what mean exactly this paramenters -> subnet 192.168.1.0 netmask 255.255.255.0?

Hello,
I only need to install DHCP server on my Ubuntu and after I type sudo /etc/init.d/dhcp3-server restart, it appears the following message,

user@user-desktop:~$ sudo /etc/init.d/dhcp3-server restart
dhcpd self-test failed. Please fix the config file.
The error was:
/usr/sbin/dhcpd3: error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory
user@user-desktop:~$

May I know how to solve? Oh babe~~~

i’ve got 2 interfaces eth0 is internal and eth1 is on another network. Every time i restart dhcp3 it assigns the server itself an IP. It needs to be static. I configured a static one in /etc/network/interfaces but it changes when i restart the dhcp3 server. Any help would be greatly appreciated

i followed this and everything looks correct…
except that even tho clients get a unique IP and same DNS as the server, they still can’t connect to the internet.
The serer does just fine (writing from it now). it gets dhcp from ISP gateway modem on eth1.
eth0 is connected to lan switch w/ static internal IP.

All the #’s look good on the clients. ip, dns, router (internal address of server, eth0).
I’m so stuck at this point. What am i missing??
WTF!!

How can I ensure at each step, configuration is done correctly, any snapshots will help me a lot.

when I installed dhcp3-server at the end it printed

invoke-rc.d: initscript dhcp3-server, action “start” failed.

what does that mean?…

Thanks. You’ve taken me 3/4 of the way there. Using your site along with the tests in the following link (http://www.linuxquestions.org/questions/linux-newbie-8/how-to-add-a-network-card-on-ubuntu-8-04-server-745702/) helped me to ensure that my ethernet cards were working and that one of them was acting as a dhcp server. Next step is to get the other ethernet card to act as a router. That part is still not functioning. Can you lead the way to a good link?

Useful link.. Do I need to remove the ethernet connector to see the MAC address of devices? or I can detect the device IP after connecting to the network..? Any way to get the MAC?

Hi. I followed the instructions above and I got what I wanted: communication between my two computers. But when I configure the DHCP client computer, it looses the Internet connection. I can ping the DHCP server, but not google, for example.

Can you help me?

Thanks.
