Re: [K12OSN] Network boot hangs

I've seen this happen before, back when something was haywire with my client's NIC; it was one of those gradual failures.  Swapping NIC's did the trick then.  I've also (rarely) seen an NFS misconfig do it; this is rare because it's autoconfig'd during the K12LTSP setup.  I'm assuming here that you've left /etc/dhcpd.conf (or /etc/dhcpd-k12ltsp.conf) at its stock config.

Can you try this:  boot a thick client Linux box, try mounting /opt/ltsp/i386 from the LTSP server, and copying everything under there to a test directory on the thick client?

Also, do you have another kind of thin client to try out to see if it happens there, too?

Do you GNU?

I had a similar problem and found that some clients would not boot with
an etherboot cd, but they would boot with a gPXE cd.  Try that.  You
can get it from www.rom-o-matic.net.  When it comes to the driver
selection part, choose gpxe from the drop-down list.

The system is not really frozen, but nothing happens.  I have a few
PCs, and all of them exhibit such behavior. I have observed some NFS
between the server and the client before it hangs.

Does anyone have any suggestions what can be wrong with the clients?
