Re: Diskless PXEboot crashes at kernel loading.
Hi all, I can't emphasise enough how useful running a TCPDUMP on the server in question is to find out what subtle thing it is that I missed. Generally speaking a quick-crash like that is a file not being found like the modules directory or something silly like that. If you dump the NFS traffic you will probably see the client asking for a file handle for file X and getting denied by the server. If you're not familiar w/ TCPDUMP, here are some handy commands: # Avoid SSH and dump everything to the screen... tcpdump -s 1500 -X udp # Write it to a file so you can open it in ethereal later... tcpdump -s 1500 -X -w nfs.dump udp # Read in the dump file and read it through less, should you not want to us # ethereal after the last step. :) tcpdump -X -r nfs.dump |less Note that if you have a slow or missing DNS entry, give these calls a -n to just get the data and not worry about the ND entries. Hope this helps! PXE boots are never kind. :) Sam Baskinger Software Engineer Lumeta - Securing the Network in the Face of Change Lumeta Corporation And the crash happens. Note that the crash occurs for whatever option 1 to 6 I choose from the FreeBSD boot menu. Does someone understand the crash messages? Not that I understand those messages but some time ago I've had a similar case. It took me some hours to realise that I try to load amd64 kernel to i386 diskless station... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Diskless PXEboot crashes at kernel loading.
