Can't find ks.cfg file after booting from network

Experimenting with RedHat. I just created a DHCP/NFS server to do Kickstart installations. I can successfully boot from the network from this server, it goes thru the motions of loading the O/S it's ramdisk, but then I come to a point where it tries to find the kickstart file, I get a message saying "Error opening kickstart file (null): No such file or directory."

Firstly, where does expect ks.cfg ?
Second, where do I define the location of ks.cfg ?

>>> here's my entry in dhcp.conf, it finds the O/S to boot <<<

allow booting;
allow bootp;
class "pxeclients" {
match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
filename "linux-install/pxelinux.0";

>>>>>>>> end <<<<<<<<<<<<<<<

I used system system-config-netboot and defined the location of ks.cfg in the "Kickstart field" nfs:


To test location and nfs, I successfully booted off a RH cdrom, typed "linux ks=nfs: and was able to install without any prompts.

any suggestions appreciated.
thanks in advance,

I use kickstart over FTP and HTTP (not NFS though) and I've noticed it can be very finicky about the way the network is set up. The first thing I'd check is the NFS server logs to see if the exported share is even being mounted. There might be some NFS permissions problem that is causing the NFS server to deny mount requests to that particular machine.

If it is being mounted, check that the path to file on the share is correct relative to the root of the NFS mounted partition. To be honest I'm not sure how kickstart does this so you might have to go to the anaconda text terminal (alt+F3 or alt+F4 during the install) and see the log of what exactly anaconda is doing to get the kickstart file.

If all of that fails, try to see if you can do it via FTP or HTTP and see if you have a similar problem. If so it may be a network problem in the way anaconda sets things up. Test if you can ping from the server to the machine being installed.

Finally got it working.

I could not get to the Anaconda text terminal, but I was placing the ks.cfg inside the same directories containing the RPMS (in the RedHat directory and Fedora directory respectively).

I placed the ks.cfg files on the same directory Level as the RedHat/Fedora RPM directories and the PXE install found both ks.cfg files and the O/S Install trees.

Thanks again for the suggestions.
