Hi I have a nfs debian amd64 server, with a few linux clients that is working well. I recently tried to attach a mac osx (10.5 Leopard) client. Everytime I attached it would hang when i attempted to use the mount on the nas box I have this line in /etc/exports /exports/shared -async,no_subtree_check,no_root_squash,insecure,mp=/exports/shared 192.168.8.0/22(rw) I mounted with this command mount -t nfs -o rw,async,rsize=32768,wsize=32768 nas.hme1.samad.com.au:/exports/shared /mounts/shared I then tried df -h & ls -l /mounts/shared & umount -f /mounts/shared & all the commands failed to return, I could not kill them with -9, I had to reboot I have attached a tcpdump (tcpdump -pni eth0 ether host xx:xx:xx:xx:xx:xx -s 9100 -w nas.capture.dmp) on the nas box a copy of the dumo is at www.samad.com.au/~alex/nas.capture.dmp I tracked it down to --manage-gids - when I remove this from /etc/defaults/nfs-kernel-server everything works fine. Note though, the UID's, GIDs are not synced between the linux box and the mac box. so the 2 users I have on the mac box uid 501 & 502, do not exist on the nas box I read that manage-gids was a means of handle a uid with more than 16 gids and it was protocol compliant, so I have opened a bug report with Apple, and opened a bug report with debian I have had a quick look at the source code, but it looks more like something that is in the kernel. Is there another place I can log a bugreport for this ? Thanks Alex
