DHCPD or DHCPCD

[siaz4t]

Hi Every one.
I have written a small application using gtk2.0. Also i have prepared a
bootable cd image so that when i boot from the cd my application runs.
For this purpose i have used kernel 2.6.14 statically compiled (without modules) and
isolinux.bin as a bootloader while using the suse linux
Also i m using Xvesa server for X support with icewm window manager.

I want to configure network for my bootbale disc.
Using a mannual networking that is by giving ip address and netmask, i got success and the network was configured. But now i want to configure the network automatically. But i m not getting the right path.
I m trying to use dhcpcd deamon to automatically configure the network but all my efforts are not ending in a success.
What should i use dhcpd or dhcpcd?
I want to know the correct steps to configure network automatically (i-e without giving an ip address or netmask).
Please help me this matter
Thanx

dhcpd is the dhcp server daemon, and dhcpcd is the dhcp client daemon.

To automatically acquire an ip address, your server must be running the dhcp server daemon (dhcpd), or any other service that listens for client requests and assigns them ip addresses automatically through dhcp.
If your server isn't running a dhcp daemon, you can't acquire an IP address automatically.

if server is running,
then from client side i only run dhcpcd?

[runningwithscissors]

Yes.

Thanx dear.
I tried dhcpcd. The network was configured but there was no file named as "dhcpcd-<interface>.pid" in the /var/run directory.
When i ping the server it was working.
On the other hand, i tried the same thing on a second pc on the same network, but i this case nothing happend. the network was not configured.

I m using dhcpcd v.1.3.22-pl4 for this purpose.
I tried the command
dhcpcd -d <interface>

Any thing more i need to do?

I am trying to connect with the server. I am not trying to connect to the machines outside the network.

By using the "dhcpcd -d eth0"
the log file i received in the /var/log directory with the name "message" is

May 8 12:03:34 (none) user.info kernel: skge eth0: enabling interface

May 8 12:04:44 (none) local0.err dhcpcd.exe: wrong interface name ""

I cant understand it. Is "eth0: no IPv6 routers present" the problem?

[runningwithscissors]

No, the no ipv6 routers present message is not an error.

If the same server is assigining addresses to your other machine via dhcp, then I think the problem lies with the client machine, provided this machine is on the same network as the other machine that succeeds in acquiring an address. Are you blocking incoming traffic to your client machine in any way? (Improperly configured firewall?). The client machine is simply not receiving a response from the server.

I can't think of any other reasons except for incoming traffic on the client being blocked. Maybe someone else on the forum with a better understanding of the DHCP protocol may have more ideas.

Thanx for help me

Is there any other way to configure network without dhcpcd or dhcpd?
