John,
Sorry...just to make things clear.
eth0 works to get the dhcp/tftp request and eth1 does not.  However, I tried
using both is what I meant.

We have a problem with dhcp, the networking folks here did not enable
"spanning tree" on the switch ports, until that happens I am using static
ip.   I double checked the syntax etc.

I don't understand... pxelinux works and can load the kernel/initrd,
and the kernel/initrd doesn't work. Is that what you said?

Sorry for the confusion John.

pxelinux works and it loads the vmlinuz and initrd.



How does the BIOS know to load pxelinux, and where to get it? Doesn't
that require dhcp (or at least bootp)?

How does pxelinux get its menus and then the kernel? Doesn't that
require dhcp (or at least bootp) too?

And then the kernel/initrd can't get the IP address the same way. Have
I got the facts straight?


Actually I have dhcpd configured for static IP address. Not for a range of IP addresses to pick from. dhcpd is running. After PXE loads up the kernel, I think the installer anaconda uses dhcp to again look for the ks.cfg file. This is after the menu. That's the part which does not work. That's why I put in the static IP's in my default file under label 1. Putting the static IP's don't work as well.


Thanks

Thanks Colin for the quick response Yes. It does have. It's a Dell PE2950.

I have already tried that option as well. I tried both ksdevice=eth0 and ksdevice=eth1 and they don't work.


If you can connect all network interfaces, that might help, because it then doesn't matter whether either one or both is used.

If you run arpwatch that will report on which interfaces are used (by mac address and IP).

Does the machine you're on have multiple Ethernet interfaces?  If so, what
you may find is adding 'ksdevice=link' will assist.

Subject: Unable to get any http requests: Unable to retreive netstg2.img
file

Hi I am sure there is some information regarding my request, but I am unable
to
find it, hence the post.

I configured my kickstart server using http.

I am able to pxeboot the client, but my client is not able to get the
netstg2.img file from the server.

I am able to http into my netstg2.img directory from a web browser from
another server in the same subnet successfully.

Also I tried to put in a boot cdrom and run the following:

Linux ks=http://<ServerIP>/ENT_LINUX_64/Enterprise/ks.cfg ip=<ClientIP>
netmask=255.255.255.224 gateway=<GatewayIP>


I have never used static IP for ks, I alway configure everything I can with dhcp. However, I do know that that's not the format the kernel expects for the ip parameter. Check your documentation, if I were writing a script tp parse ip= then I'd conform to the existing standards (that is, the way the kernel expects it), and that's what works with Ubuntu.



Still no luck. It goes straight to the cd installer.

I tried to tcpdump the traffic on the MAC address of the client, it
outputs
the tftp information and after that it stops.

I don't see any http traffic coming from the client.

That's fairly consistent with you specifying ip= incorrectly.

btw, if you're using PXE, the why are you trying to spectify static IP info?

btw, as I recall, pxelinux has an option to pass on the IP address info it gets in the proper format for the kernel to parse.


I'd appreciate some help in this regard. I've spent all day trying to troubleshoot this but no luck.

Thanks Much
