The smbumount manual says: "With this program, normal users can unmount smb-filesystems, provided that it is suid root. smbumount has been written to give normal Linux users more control over their resources." I installed it as setuid root: -rwsr-xr-x 1 root root 618675 Apr 7 23:11 /usr/bin/smbumount Then I use smbmount to mount a share: smbmount //server/share ~/mntpoint rw And it works fine. But when I want to unmount it as a user: smbumount ~/mntpoint I get this error: You are not allowed to umount /home/nir/mntpoint So what is the (mount) point in this? what am I doing wrong? btw - I also installed smbmnt as setuid root - otherwise it will not let me mount at all as a regular user.
