nfs woes
Hi guys,
I have a diskless workstation setup (which I had working fine) and am
having trouble incorporating 100Mbps NICs into the picture.
I have 10Mbps NICs and 100Mbps NICs, but netboot and etherboot only
support the 10Mbps NICs I have.
However there are ways around this - just have the workstation use the
10Mbps NIC to get an IP, grab its kernel, mount root via NFS and begin
booting. While booting, it configures its 100Mbps NIC and remounts root
over the 100Mbps line.
The problem is that when trying to mount root via the 100Mbps line I keep
getting permission denied error messages. So it is failing at literally
the very last step.
I became very familiar with all the config files and such while getting it
to work with just 10Mbps NICs, and from what I can tell everythig seems
configured correctly. I am not sure what to try next.
here are the relevant details:
The network is setup such the 10Mbps and 100Mbps networks are entirely
sepparate. Physically, there are no connectiosn between the two, and it
is configured so that 192.168.0.* is 10Mbps and 192.168.1.* is 100Mbps.

If you guys can think of anything I might be missing, or if there are any
pertinent config files I have left out, please let me know.
by the way, if you could please reply to cell@cs.utexas.edu, as I am not
currently subscribed to the list.
thanks,
