'owned by uid 1000 instead of uid 0.' What does it mean? (Resolved)

[leadwt]

I'm sorting out a Kdesudo-password issue and I went to edit 'mtab' and got the following output:


Error: "/var/tmp/kdecache-rupa" is owned by uid 1000 instead of uid 0.

None of this means anything to me but I wonder why I have an apparent 'ownership' problem i.e. 'owned by uid 1000 instead of uid 0'

Is this an issue can anyone tell me

Thanks

rupa@pollypig:~$ rupa@pollypig:~$ sudo kate /etc/mtab

NEVER start a gui program (like kate) with sudo. ALWAYS use kdesudo.

Arh right but what actually is the difference?

The difference is if you do what your not supposed to, you get those error messages! :P

The security and stability of linux is directly linked to file permissions and the permission structure of executables.

When you launch a GUI program as super user without the GUI interface (aka sudo instead of kdesudo) you threaten the security and stability of your install - hence the error messages.

At the very least, you'll likely end up making some GUI programs un-executable because you changed the permissions of data stored in your /home. At worst, you might render your system totally unusable.

Here's a simple test. Open a terminal window and type:

ls -la ~/ | grep root

if you get any output other than

drwxr-xr-x 8 root root 224 07.06.2010 09:56 ../

you've done some harm (most likely very slight).

oshunluvr - Pleased to say I got nothing more than what I should have!

Snowhog - Thanks for the link

A lesson learned, regretfully I got the original instruction from a post on the Ubuntu Forum.
I shall go and set that to rights.

Thanks.
