nfs problems - read/write, restarting nfs_damon

[Robert.Land@t-online.de (robert_wilhelm_land)]

two linux boxes are connected via nfs to each other:

MINI (kernel_2.2.17) <----------> GOOFY (kernel_2.0.38)

the /etc/exports on GOOFY:   /home/rland MINI(rw)



After rebooting I do a 
MINI:/home/rland# mount -t nfs GOOFY:/home/rland ./testdir

after this ./testdir changes from:
drwxr-sr-x    2 rland    rland        4096 Nov 30 18:38 testdir
to
drwxrwxr-x   24 1001     users        4096 Nov 27 12:17 testdir


what has happened?

being on MINI, ls ./testdir shows all files & directories on the
mounted GOOFY directory but a ls -l fails with the the same filelist
compareble using "ls" but each file with a post_remark "no such file
or
directory"

I did a "touch ./testdir/this_is_a_testfile", but MINI remarks "no
permision", although the exports on GOOFY should be clear enough.



Additionally, how can I restart the rpc damons on GOOFY without
rebooting? I tried:
killall -HUP /usr/sbin/rpc.mountd
killall -HUP /usr/sbin/rpc.nfsd
or
killall -HUP <pid>
killall -HUP <pid>

but no reaction, "ps -aux|grep rpc"  displayed both processes with
their old timestamp



Would someone kindly help?
