Hi


I am having some problems with my new mini mac connecting to my debian
amd64 nfs server. I have other linux clients that are working well with
nfs. I have raised this on the apple forums, but the suggestion (see
the tcpdump) is that the server is not responding.


on the nas box

/exports/shared
-async,no_subtree_check,no_root_squash,insecure,mp=/exports/shared
192.168.8.0/22(rw)


done on the nas box
tcpdump -pni eth0 ether host 00:16:cb:b0:87:15 -s 9100 -w
nas.capture.dmp (available via
http://www.samad.com.au/~alex/nas.capture.dmp)


I did this on the mac client
mount -t nfs -o rw,async,rsize=32768,wsize=32768
nas.hme1.samad.com.au:/exports/shared /mounts/shared


and then tried

df -h & (did not return)
ps -ef
dmesg | tail (lots of server not responding)
tcpdump -pni en0 not port 22 (did not see anything - could have let it
run longer!!)
mount & (finished showed the nfs mount)
ls -l /mounts/shared/ & ( did not come back)
umount -f /mounts/shared/ & (did not come back)

These are the last 3 lines from the dump from nas

Seq=1021 Ack=589 Win=524280 Len=0 TSV=1053569866 TSER=9155080

the response i got back from the mac mailing list

Packet #41 is an ACCESS call by UID 502 that does not get a response.
Packet #42 is an FSSTAT call by UID 502 that does not get a response.

>From the looks of it, it would seem the server is choking/stalling
on requests that are being performed by the non-root credential:

UID 502
GID 20:98:102:101

Something definitely seems wrong on the server.



my nas box talks to a ldap server, I don't have uid 502, but that
shouldn't stall nfs I would have thought.


Any help on how to track this down or ideas on the problem ?

Thanks
Alex

Try

/exports/shared 192.168.8.0/22(rw,async,no_subtree_check,no_root_squash)

and "exportfs -rv"

On the Mac, add to /etc/fstab (assuming your Server is 192.168.8.5):

192.168.8.5:/exports/shared /yourdir nfs locallocks,udp,sync,resvport,bg,intr,rsize=32768,w size=32768 0 0

and run "automount -v".

PS: Locking doesn't work as expected on Leopard. Use "nolock" or
"locallocks".

still seem to have the same problem, df -h locks up. tried with no lock,
ro, removed the rsize and wsize

What about tcp instead of udp?

tracked down the problem (with the help of another person on the mac
interop mailing list), seems like when i stop using --manage-gids,
everything is okay, I have some users with more than 16 gids !

The lovely woman-child Kaa was mercilessly chained to the cruel post of
the warrior-chief Beast, with his barbarian tribe now stacking wood at
her nubile feet, when the strong clear voice of the poetic and heroic
Handsomas roared, 'Flick your Bic, crisp that chick, and you'll feel my
steel through your last meal!'
