Fabio, Jim,
Changed the nic in the workstation to a 3c905 - problem remains.
Went back to connecting them into a 3com 10/100 hub and added a notebook computer running redhat 6.2. From the notebook computer I can mount the /opt/ltsp/i386 exported fs and access it without error.
Did notice I was setting up dns and default gateway in the dhcpc config even though not running bind/named on the ltsp server. I commented out the domain-name-server and router options, and cleaned up /etc/resolv.conf so there was no mention of a name server on the systems.
Am able to ping from server (192.168.0.254) to workstation (192.168.0.10) and notebook (192.168.0.111) and from notebook to both server and workstation.
/var/log/messages shows that workstation successfully does authenticated mount of /opt/ltsp/i386.
But still no-go on getting workstation to access mounted filesystem as root after the pivot_root.
I'm open to any and all suggestions on where to go from here.
Thanks for all the help.
Toby

Hi Toby,
maybe it is irrelevant, but what exact type of eepro100 are you using?
I ask because I had all sorts of problems, from ceased network functionality
to complete PC lockup, with eepro100 kernel driver, especially with the
559er incarnation.
