Thanks. It always happens that I struggle with something for a couple
of days and then figure it out 20 minutes *after* posting to
Anyway, I now realize I need to choose "Intel Pre-boot environment" on
the thinkpad. When I try that when wired it finds the server, loads
the kernel, goes through the hardware recognition process and then,
when it finishes executing something called /scripts/nfs-preboot, I
get an endless stream of Read: Connection Refused. If I CTRL-C out of
those I get a message saying the server doesn't have NFS over TCP and
I'm left at an ash prompt.
I've checked /etc/exports (it's sharing /opt/ltsp *(ro,no_root_squash,async)
, and anyway, it must have loaded the kernel from somewhere), checked
the firewall settings (even turned it off at one point) and my
hosts.allow looks like this:
I still end up stuck in the same place. What else should I check?
(I'm hoping the magic of posting to the list will work here. I should
discover my error in about 19 minutes....)
