Re: [K12OSN] NFS Error



I reported this same problem under the heading

mount: RPC: Authentication error; why = Failed (unspecified error)

I have posted it twice to this group, and also posted to a number of comp.os.linux groups and been answered by a big gaping silence.
My thin client has been a doorstop since late December. Is this
really such an obscure problem that nobody has a clue how to even
approach it?

Just to consolidate the two threads, I'll repost what I know:

The /etc/exports file worked before, with the single line

/opt/ltsp *(ro,async,no_root_squash)

Barry has posted a much larger /etc/exports file, which I presume includes
entries needed for running some apps locally on the thin client.
For running everything on the server, I know that the above line is
all that is required. Or all that was required, before the F9 update.
It is possible that some of the lines in Barry's file are necessary, but none
of them mentions /setuproot, which is in the error message above.
