Run a script as any user

I have a script that displays the IP Address of a given network interface / device name.

I have placed it in /bin/ip.sh

Code:

[root@mahadeva ~]# ip.sh eth0

192.168.56.15

But as I run it as another user, it doesn't work because the script contains the "ifconfig" command:

Code:

[root@mahadeva ~]# su - DEV

[DEV@mahadeva ~]$ ip.sh eth0

/bin/ip.sh: line 3: ifconfig: command not found

Any user can run ls command, for example, without any root privileges. I just found that my script and ls have identical ACL:

Code:

[DEV@mahadeva ~]$ getfacl /bin/ls

getfacl: Removing leading '/' from absolute path names

# file: bin/ls

# owner: root

# group: root

user::rwx

group::r-x

other::r-x



[DEV@mahadeva ~]$ getfacl /bin/ip.sh

getfacl: Removing leading '/' from absolute path names

# file: bin/ip.sh

# owner: root

# group: root

user::rwx

group::r-x

other::r-x



[DEV@mahadeva ~]$

So, how can I make my script to be executable by any user?

I looked at the visudoers file but got confused as to what entries I should make there (if that is a possible solution).

You don't need privileges, you need to specify the path - /sbin/ifconfig - since 'command not found' means that it's not in your user's path.

Your problem is "command not found", ie ifconfig is not on the user's PATH. Use the full path (/sbin/ifconfig) in your script.

That will help. But if your script wants to do things that normally only root can do, that won't be enough.

What is the solution for that? :D

chmod the script suid root. But are you really sure you want to do that?

Yes, I want to experiment anything I can think of.
