setting directory permissions

[chagmaier]

I cant seem to get my directory permissions quite right... i want to make /media/OS/Users available to rwx for owner and group. owner is chris, group is Family. what would the correct syntax be for the konsole? i have tried to kdesudo dolphin and then set the permissions through the dialog, but it doesnt change!
what am i doing wrong?

thanks again, and sorry for all the questions!

Re: setting directory permissions

One way is to change the ownership to chris:family

sudo chown -R chris:family /media/OS/Users

You will then want to add your user (chris) to the group family.

Re: setting directory permissions

this is what happens...

chris@Harper-Inspirion-1545:/media/OS$sudo chown -R chris:Family Users
sudo: unable to resolve host Harper-Inspirion-1545
chris@Harper-Inspirion-1545:/media/OS$ls -l
drwx- - - - - - 1 chris chris   4096 2011-07-18 08:08 Users

Re: setting directory permissions

Do you have the group Family created? You are using an uppercase F, yet your post indicated a lowercase f. Case sensitivity has to be observed in Linux.

Re: setting directory permissions

the group Family was created through the User Management in the System Settings menu...it does have a capital F.

Re: setting directory permissions

The error here is coming not from your chown attempt, but from sudo. Note the part in bold:

chris@Harper-Inspirion-1545:/media/OS$sudo chown -R chris:Family Users
sudo: unable to resolve host Harper-Inspirion-1545
chris@Harper-Inspirion-1545:/media/OS$ls -l
drwx- - - - - - 1 chris chris 4096 2011-07-18 08:08 Users

I'd guess that you need to fix your /etc/hosts file. You should see the following line in it:

127.0.0.1 Harper-Inspirion-1545

Would you verify that for us, please?

Re: setting directory permissions

SteveRiley,

I did manage to correct this...I had changed /etc/hostname and forgot to update /etc/hosts
/etc/hosts now reads:

127.0.0.1   localhost
127.0.1.1   Harper-Inspirion-1545

should the second like have 127.0.0.1 instead of 1.1 ?
the sudo error doesnt come back, but im still not able to change rwx attributes...

Re: setting directory permissions

No. The IP is correct.

[SteveRiley]

Re: setting directory permissions

hostname should contain only the name of your host, no IP addresses. As far as hosts goes, yes snowhog corrected me; I let old habits override my typing. (Actually, 127.any.any.any will work.)

Do you see any output at all now when you try the command?

chown will change the owner and group........"chmod" changes the rwx attributes.

Well don't I feel like a moron right about now. :P

Re: setting directory permissions

$sudo chmod 771 -R /media/OS/Users

i press enter and it "works/pauses" for a moment then returns to the prompt. checking (ls -l) again shows NO changes to the directory.

http://ss64.com/bash/chmod.html ...towards the middle of the page where it gives syntax examples, it only shows changing permissions for files. am i trying to change permissions for "Users" file instead of dir?

thanks for all the help guys, im off to work now, it may be late this evening before im able to reply again. (9-10pm EST)

Re: setting directory permissions

can we assume you have /media/OS/ being mounted at start with an entry in /etc/fstab ?

if so please post the line from fstab.

if you have umask values set in fstab your chmoding will be ignored in favor of the values set in fstab.

hear is a line from my fstab for a mounted partition I use for my data.

UUID=6d8f8f09-a999-4405-ad9a-e0df9224a3ba /mnt/data ext4 defaults,rw, 0 2

it's permissions are

vinny@vinnys-HP-G62:/mnt$ ls -l
total 8
drwxrwxr-x 8 root vinny 4096 2011-09-09 22:34 data

the group vinny could be anything as long as you are in that group.

this works well for me.

That is slightly misleading. For non-posix filesystems (like ntfs or fat), file and directory ownerships are set at mount time using mount options (uid, gid, umask, dmask and fmask)...and you can't use chown or chmod to change the ownership or permissions (since these filesystems don't support POSIX ownerships/permissions). These mount options are not used with POSIX filesystems (like ext).

This is a good way forward.

Aaaa,thanks for the clarification. I was working just from the man page and it didn't specify.
