[9fans] srvssh: access permission denied

[Richard C Bilson <rcbilson@plg2.math.uwaterloo.ca>]

Thanks to all who made suggestions about my rtl8139 problems.  I'm happy to
report that things are working very well now.

Since, unfortunately, I don't get paid to develop on plan9, I'm attempting
to use the system on my home machine as a way of accessing files on the
various unix machines that I am supposed to be working on.  This almost
works perfectly -- my only gripe is that, for some reason, srvssh won't
work unless I disk/kfscmd allow first.  To wit:

term% pwd
/usr/rcbilson
term% du n
0	n/apl
0	n/plg
0	n
term% bind -bc n /n
term% srvssh -u /u/rcbilson/opt/bin/u9fs apl.uwaterloo.ca apl /n/apl
srvssh: access permission denied

If I disable permission checks, run srvssh, and then enable them again,
the mounted fs works fine.  It seems to me that this should not be
necessary.

P.S. Is it just me, or are the u9fs sources in bad shape?  When I tried to
compile it about a week ago, it failed -- it looks as though somebody
ripped the des.c functions out of another file, without making sure that
macros like DESKEYLEN are defined.  I got it to work, though, with a bit
of hacking.
