ls, universes and nfs

[Stefan Petri]

Configuration : Targon/35-M50 with TOS3.2 and NFS3.2
	(thats a clone of Pyramid 9810 OSx4.0 , I think)
	linked via ethernet to some Sun3/60 (SunOs 3.5 and 4.0.3)

Today I tried for the first time to import a filesystem via nfs :
# mkdir /usr/mnt
# mount mplsun:/usr/users /usr/mnt
/usr/mnt: not owner
-> what does this mean ?
# mount
/dev/iop/pdisk00a on / type 4.2 (rw,noquota)
/dev/iop/pdisk00k on /usr type 4.2 (rw,noquota)
/dev/iop/pdisk00l on /u1 type 4.2 (rw,noquota)
/dev/iop/pdisk00e on /u2 type 4.2 (rw,noquota)
mplsun:/usr/users/mplsun on /usr/mnt type nfs (rw)
-> I think, the mount succeeded
# ls -a /usr/mnt
#
-> The ls did'nt even show "." and ".." !
# ls -ld /usr/mnt
drwxr-xr-x 14 root          512 Sep 22 13:39 /usr/mnt
-> The 14 links are correct for the mounted filesystem.

And then : (our root-account is in the att-universe)
# ucb ls -aC /usr/mnt
.		bluemel		jabs		lost+found	schmidt
..		broeke		klebsch		meier		tmp
bachmann	forth		linde		moeller
-> This gives the correct entrys.

I wrote some programs to test the stat(2-att), fstat(2-att), stat(2-ucb) and
fstat(2-ucb) Systemcalls. They all work on the remote-mounted FS.
What doesn't work is the readdir(3X-att) call, opposed to the readdir(3-ucb)
call.

I think, this kind is of transparency isn't what they call network-transparent-
filesystem ?

S.P.
