SU/program execution permission problems


Hi,
I'm having some troubles. I compiled a C program and didn't get any errors. I go to run the program and get this
Code:
darinf@localhost c $ ./program
-bash: ./program: Permission denied
Here is 'ls -l' output
Code:
-rwxrwxrwx  1 darinf users 13641 Aug 17 16:34 program
I also ran
Code:
chmod u+x program
and still nothing. I also go to su to root and I can't, I type the password and get "Permission denied" although I can use the same password to log in as root, just not su to root. And when root I still get the same errors when running the program.

Any help is greatly appreciated

Thanks,
Darin

Try to set root password in more traditional UNIX fashion,
you can set the root password by typing
#sudo passwd root.

This will allow you to use su or login as root on the console.

If you need a shell with root privileges, run
#sudo -s

But usually when I run externally GCC built program as user, Linux requests permissions.
chmod -x

But wouldn't chmod -x make the program unexecutable?

I didn't think it was necessary to make a compiled C prog. executable, but i tried and it still didn't work. Also, some interesting shell scripting problems are coming up, for instance, after creating a hello world script here is what happens
Code:
darinf@localhost c $ chmod u+x test
darinf@localhost c $ ./test
-bash: ./test: /bin/bash: bad interpreter: Permission denied
darinf@localhost c $ /bin/bash test
Hello world
I don't know if this is related, but still interesting

Do you think to check it again with GCC will make any sense?
Just yesterday one our member sent me his program compiled with g++ and I had the same thing, but typing
#su
#chmod +x lesson
solved the bugger

Fixed one of the problems! It turns out the programs are on a seperate harddrive, a hardrive that doesn't have exectuable permisisons, everything works fine in /

But su still doesn't work :|
