I rebuilt everything with checkout from today and tested with osx and linux clients. both show the same results, viewing traffic with wireshark shows no response packet sent when using udp. osx: dumb:~ antab$ mount_nfs -o udp 192.168.1.254:/home/antab/avr32-root test/ mount_nfs: bad MNT RPC: RPC: Timed out\n mount_nfs: bad MNT RPC: RPC: Timed out\n mount_nfs: can't access /home/antab/avr32-root: Permission denied dumb:~ antab$ mount_nfs -o tcp 192.168.1.254:/home/antab/avr32-root test/ dumb:~ antab$ umount test/ Bad MNT RPC: RPC: Timed out (osx seems to always send the UMNT rpc with udp) linux: antab@thordis:~$ sudo mount -t nfs -o udp 192.168.1.254:/home/antab/ avr32-root test/ mount.nfs: mount system call failed antab@thordis:~$ sudo mount -t nfs -o tcp 192.168.1.254:/home/antab/ avr32-root test/ antab@thordis:~$ umount test/ Arnar Mar Sig
