setuid problems...

[ScRapZ_1]

Just a quikkie...

When I try to setuid a file (we'll call it "file") for example chmod 4755 file I get:

chmod: file: Operation not permitted

...now I find this funny seen as Im logged in as root, and I'm supposedly "god" of the box, and it wont let me do a simple thing like that!?!!?

Any help?

Try to set the setuid by typing "chmod +s filename

[ScRapZ_1]

No go... still the same problem

BUMP!

Does this happen on any file or only on a specific one?

Ive only had to try it on two files that I downloaded, but gimme a sec...

...hmmm, it seems that I can do it to, say, a file I typed up myself. Hangon, I know what you're going to say... "chown root file", I already ahead of you... and it STILL wont work.

So I cant setuid the files I've downloaded...

What if you duplicate the file (maybe with umask 000 before the cp)? Is the new file still rebel to chmod?

Are those downloads complete. Maybe those are un-complete, corrupted files.

...ahem.

Silly me trying to do it from a mounted drive. Copied it over to /usr/local/folder and it worked first time. :rolleyes:

Unfortunatly, that brings me to my next question of neverending annoying questions. Probably something as obvious as the last one, but not from what I can see.

I try to _run_ the file, first by going to the dir it lives in, (ie: /usr/local/folder) and trying to execute it (ie: ./file) and it comes back saying:

bash: ./file: No such file or directory

I can see it, ls it, edit it, do stuff to it... but not execute it. It apparently doesnt exist when I try...

I hope its not as blatenly obvious as my lst stuff up. :D

Is it market as executable? Is it a script with a she-bang (#!/bin/bash or perl, ...).
If so, is the she-bang correct for your system?

It could also be a script calling another program, not present on your system.

Its marked as executable.

I dont know what it is, but if I view it with the view program in X or with vi, the first 3 letters are ELF.

Dont know if that helps, but I might give up after this... getting bald at to early an age. :D

ELF is an old binary format taht should be supported on any linux distribution, AFAIK.

I don't know why he is bugging ...

Sorry.
