I reproduced this problem per your setup on Ubuntu 10.04 LTS server and client. There nfs4 would not work (e.g. permission denied), but nfs3 works. However, on Oneiric as server neither nor works:
spindler@spitfire:~$ sudo mount -t nfs -o vers=3 meteor:/home/spindler/export /mnt-meteor spindler@spitfire:~$ /mnt-meteor/hello bash: /mnt-meteor/hello: Permission denied spindler@spitfire:~$ mount -v | grep mnt-meteor meteor:/home/spindler/export on /mnt-meteor type nfs (rw,vers=3,addr=192.168.1.122) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/833300 Title: NFSv4 mount point does not allow binary files to run when permissions are set only to execute To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/833300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
