mount smb drives as non-root user?

cdhgee · 07-31-2005, 10:02 AM

I have a Windows XP laptop on which I have some shares which I access from my Linux desktop machine. At the moment I'm unable to mount the shares as any other user than root.

First, a bit of background. I've got the following mount-point defined in /etc/fstab:

Code:

//cchqdave/c$     /mnt/laptop             smbfs   user,credentials=/home/david/.smbpasswd,rw,noauto       0 0

If I try to mount this mount-point as myself (an unprivileged user), I get an error:

Code:

[david@malvern ~]$ mount /mnt/laptop
smbmnt must be installed suid root for direct user mounts (501,501)
smbmnt failed: 1

So I took the suggestion and made smbmount setuid root:

Code:

[david@malvern ~]$ sudo chmod u+s `which smbmount`

And tried mounting it again:

Code:

[david@malvern ~]$ mount /mnt/laptop
libsmb based programs must *NOT* be setuid root.
12687: Connection to cchqdave failed
SMB connection failed

Which is weird. Anyone got any suggestions? I really don't want to have to do sudo mount /mnt/laptop every time. It's probably worth mentioning if I do do sudo mount /mnt/laptop then it works fine and I can access my shares without any problems - I just don't like having to stick in the sudo password every time because it's a pain.

Um ... this is not how FC4 expects you to use smb shares ...

You can set up the FC4 machine as the server - set the workgroup etc - and the share appears in your XP laptop. The whole thing works through the gui.

Well there are two binaries, smbmnt and smbmount. It says smbmnt should have suid, but you made smbmount suid.

I don't know what the difference is, but I know there is a difference. Try to set the suid bit for smbmnt instead of smbmount, and call us in the morning.

Why not use PAM_MOUNT. Alot better and secure then using fstab or smbfstab

i know this thread is way old but the original poster never replied to say if it was fixed or not, but i did what TexasDex mentioned and did

Code:

chmod u+s /usr/bin/smbmnt

and the mount worked fine in my fstab. i had the same setup as the OP and could not get the share mounted or if i did, i didnt have write access. now i do!

thanks

I solved a similar problem differently
