On 29/04/07, Douglas Maus [EMAIL PROTECTED] wrote: Is it possible for users (non-root) to mount NFS exports? Well, on Linux, and depending on the amount of regular users who should be able to mount their private shares, you could add a line to your fstab (I think this is the 'users' or 'user' option, depending on your needs [1]). But that's a dirty solution, for home or small networks. By the way, is anyone aware of the reason why this option is not present in OpenBSD's mount [2] (technical, security) ? Thanks.

Any help would be appreciated. Maybe I am being dumb, but wouldn't the obvious thing be to configure 'sudo' for each user so that they can mount 'their' share (only)? This would probably be quite onerous if you had a lot of users, mind you. Tor

Actually, that's probably the simplest solution; config a user group with access, then grant sudo access to that group for the mount. Lee

Mike Erdely responded: From mount_nfs(8): HISTORY The -P flag historically informed the kernel to use a reserved port when communicating with clients. In OpenBSD, a reserved port is always used. This means to me that you will always have to be root to use mount_nfs. Unless I'm missing something. Alright, I'm confused - if you cannot use a reserved port unless you are root, thus you have to be root to use mount_nfs, then why is there a mountd option -P to tell the kernel to use a reserved port? Unless even root needs to tell the kernel not to use a default unreserved port, but rather use a reserved one. Douglas Maus
