Dhcp failed with error (Pump Told us : no dhcp reply recived.)


Hi linux Gurus,
I am trying to configure a network installation server on CentOS(2.6.9).
The point where i stucked is .
The client is not able to find my dhcp server.
The steps which i have taken is:
1) copy all the 4 cd disk to /data/network-install/x86/CentOs/RPM
2) copy all the 4 cd image to /data/network-install/x86/CentOs/ISO
3)configured NFS as (in /etc/exportfs)
/data/network *(ro,sync)
4)configured ftp as
anon_root=/data/network-install/x86/CentOs/RPM
5) Configured dhcp server by putting mac address ,hostname and ip.

Now after booting the client with CentOs 1st cd and choosing te option :-
1) Lan Boot
results: perfect (i.e it get the ip same address as mentioned in Dhcp)
2) linux askmethod
a) Dynamic Ip by dhcp
results:- fail with error
Pump Told us : no dhcp reply recived.
b) static ip
results:- proceed , but failed to mount the nfs share and anonymous dir shared by the server.


Hope the above Information will clear my situation .
I am not getting any way around, can any one show me a light.
Any suggestion is welcome.

One thing i will like to mention here is that after installation , client find my dhcp successfully . and also

Thanks for your Time...

Not sure if I can help, but let's clarify.

It sounds like you are configuring another computer, presumably in your home or office, that is acting as the DHCP server. Right?

Or did you mean the CentOS PC is also acting as a DHCP server?

When you boot with the static IP, do you have a route to the machine that has the NFS share (or to the machine that is trying to mount yours--whichever)? Can you ping it? Can you ping the anonymous server?

yes , i have centos 4.3 dhcpd server delivering ip to 20 nodes.
the same client also successfully get the ip by server , once it's been booted.

try checking the logs on the dhcp server, and the dhcp.leases file. at a more basic level, you can run "tcpdump -vn port 67" on the server to show all dhcp traffic it's seeing, you can see clearly there if it is giving a lease out to the machine or not.
