Can`t mount to /mnt in account other than root...(not owner)


In tru64 v 4.0 d, I have get NFS file sysetm form windows, I can mount it in root account:

mount -t nfs windowshost:/sharedfolder /img4 (or /mnt)

/mnt, /img4, is folders owned by root.

the other user "user", it`s home is " /img0/user " , can`t mount it to /mnt or /img4 , appear a massege " /img4 or /mnt not owner ", but "user" can mount that NFS to any folder inside its home such as " /img0/user/img4 ".

note: /img0 is a second parition in the same disk.

but "/img0/user/img4" path isn`t useful for my work, I need nessesary to make "user" mount that NFS to /img4 , without using "su".

I try to make write permission for " /img4 " folder to all users, but still the same problem.

what should I do?

man mount

To use the mount and unmount commands, you must be the root user. An
exception to this restriction is made when NFS file systems have been
explicitly exported to allow nonroot users to mount the file system. Refer
to the -n option of mountd(8) for more information.

Show actual commands with their actual
output?

How?

ls -ld /img4
ls -ld /mnt

I doubt that a normal user can mount anything
on a mount point (directory) which he does
not own (or have write permission for).

I have found "chown" - Change the owner and/or group of a file or folder. You must be root to use this command.

I well try it and tell you.

I have made:

choun "user" /img4

this have solved the prblem, it`s change the owner of /img4 to be "user", and I have made the mounting without "su".
