 |
|
It took me a little while, but I finally have my /etc/fstab setup where I'm able to mount my share as an ordinary user. Here is the line in my /etc/fstab
| Code: | | //192.168.1.77/david /home/david/storage smbfs user,uid=david,gid=david,rw,credentials=/etc/samba/stuff.credentials 0 0 |
/etc/samba/stuff.credentials has 600 permissions and is owned by david:david
Now when I type "mount /home/david/storage", my share is mounted and all is good. But when I type "umount /home/david/storage", I get this notice:
| Code: | | umount: only root can unmount //192.168.1.77/david from /home/david/storage |
In my /etc/fstab, I changed "user" to "users" and it works, but that seems incorrect to me. I think it should be "user".
So my question is: Should it be "user" or "users"? If "users", why? And if "user", how do I make it where I can umount as my normal user? |

Hi,
better to read the manpage (man mount):
| Code: | user Allow an ordinary user to mount the file system. The
name of the mounting user is written to mtab so that he
can unmount the file system again. This option implies
the options noexec, nosuid, and nodev (unless overridden
by subsequent options, as in the option line
user,exec,dev,suid).
users Allow every user to mount and unmount the file system.
This option implies the options noexec, nosuid, and nodev
(unless overridden by subsequent options, as in the
option line users,exec,dev,suid).
|
So, good luck.

According to the man page, if I use the "user" option, I should be able to unmount as well as mount. I can't. And that was the basis of my question. So I don't really see the relevance of your reply. |

Sorry,
was my fault. I haven't read it exactly enough. Ok so you are right. The user david should be able to umount the deivce.
Dunno.

Hmm...
I had the same problem, and switching it from 'user' to 'users' instantly worked.
This thread's a few months old, but it makes me curious... Why would you want to give permission for only mounting? Or why isn't there another keywored (possibly 'use'--subtracting a letter  that would make it so you could umount but not mount? I also agree that the man page makes it sound a bit like 'user' should work as well...
Just curious, if anyone knows the reasoning behind the way it's set up. |

My concern with using 'users' instead of 'user' was that anyone could mount or unmount my share. I want to be able to mount and unmount it as my own user, but I don't want any other user (other than root obviously) to be able to mount or unmount the share I have specified. |
