mount ntfs-3g with 700 for one user from the shell [SOLVED]

graysky · 2009-09-01 21:27:49

I'd like to mount an ntfs partition w/ ntfs-3g but only allow access on the Linux side to a single user. I don't want it mounted in my /etc/fstab however. I mount it on the fly now from the shell

sudo mount -t ntfs-3g /dev/sdb1 /media/ntfs_data

I know about the uid=xxxx flag that I can include in an /etc/fstab entry, but I can't seem to get the syntax correct for a shell-based mount command. Anyone?

the -o flag is what you use to put in any of those options (ro, uid=, gid=, etc...)

so just add on the -o uid=xxxx

edit: oops you were looking to change uid, not gid

Don't mess things up with UUIDS.

Always use clear device names.

I just want to limit the mount to ONLY a single user so all other users cannot read/write/execute it at all. If the user's UID is 3010 would the syntax then be:

sudo mount -t ntfs-3g -o uid=3010 /dev/sdb1 /media/ntfs_data

EDIT: that didn't work. It just assigns my user as the owner, but all others may freely rwx the partition.

Maybe try to add the umask option:

-o uid=xxx,umask=022

This should set permissions to 755 on the mount so the owner can do anything, and everyone else can only read.

Edit: to not allow anyone else to read at all, umask 077 should do it.

apollokk - you're entitiled to your opinion regarding UUIDs, but it has nothing to do with this thread. The OP is asking about UIDs.

Please read before posting.

@neddie_seagoon -

The following command you suggested worked!

sudo mount -t ntfs-3g -o uid=3010,umask=077 /dev/sdb1 /media/ntfs_data

If I ls -l the mount point, I do indeed get:

drwx------ 1 username root 8.0K 2009-08-20 14:52 ntfs_data

Thank you!
