Hello, I need to setup a super user on AIX 5.3. We are using a third party application that uses the AIX as a back office. The application uses lots of shell commands e.g. I can Administer users; Terminate, kill, snoop etc.

Now I have a problem with the kill command.
I have setup a user on AIX as an admin user but it looks like the user cannot kill other users processes..

The kill -9 returns error number 2.

Can you advise on what I have missed?

To do any changes on AIX I can use only ssh and vi. so I need some more detail instructions.

I will appreciate your help in this matter.
Thank you in advance.

"Admin User" on AIX just means that only root is allowed to change any attributes of this account. Users which are members of the "security" group can change only user accounts which do not bear the "admin flag".

So the admin status has nothing to do with privileges.

To acquire root privileges a normal user must use "su" or "sudo".

"su", if issued by a non-root user requires entering the password of the target userid. "sudo" is configurable in a way that selected users can issue selected or all commands on behalf or "root" or another user, if so configured. "sudo" uses a configuration file "/etc/sudoers" and an editing tool "visudo" for this.

"sudo" is not part of AIX, you must install it from the AIX toolbox CD which came with the OS media, or you must download it form here:

http://www.oss4aix.org/download/RPMS/sudo/sudo-1.7.10p7-1.aix5.1.ppc.rpm

Please note that sudo requires zlib, which you can get here:
http://www.oss4aix.org/download/RPMS/zlib/zlib-1.2.8-1.aix5.1.ppc.rpm

Once you downloaded both RPM packages "cd" to the directory where you put them in and run

rpm -ivh zlib-1.2.8-1.aix5.1.ppc.rpm

and

rpm -ivh sudo-1.7.10p7-1.aix5.1.ppc.rpm

Once these tools are installed learn how to use sudo, the sudoers file and visudo here:

sudo: http://www.sudo.ws/sudo/sudo.man.html
sudoers: http://www.sudo.ws/sudo/sudoers.man.html
visudo: http://www.sudo.ws/sudo/visudo.man.html

Should you have further questions how to implement and use "sudo" please let me know.
