AIX

Hello everyone

I have a question ?

Its possible to create another user exactly as root?

If not its possible what options I have to create a user like root.

Thanks for your comments.


Greetings

its usually best practice to not allow root login directly.

man sudo

Reply yes it is possible this is some times used to allow operations to do some tasks
But this is not good practice if you leave this user open. There are a few things you can do to make this save and workable. New in AIX is also role base access controls and this is a better way to control users access to some tasks.
have a look at

Generally speaking (this is not limited to AIX) every user with a user-id of 0 (zero) becomes a de-facto root user with a different login name and a different $HOME.

Still, as ravager already said, this arises several problems and is NOT recommended practice. I suggest you explain what you really want to achieve and probably there are other - better - ways to do this.

One problem for example is that several tools get their information from /etc/passwd and implicitly rely on this database being unambigous. "ls", for instance, is one of these tools: if you issue an "chown myadmuser file" for some root-equivalent user "myadmuser" with UID 0 and then do an "ls -l" you will see that the owner si displayed as "root" - simply, because "root" si the first entry to match UID 0 in /etc/passwd.

I hope this helps.

I have done this just today

Though this is not a good practice ...i had to do coz of my requirement

add a user (say "adm") assign the primary group of the user to "system"

#useradd -g <primary_group> <user_name>
#useradd -g system adm
set the password of user "adm"
#passwd adm
then
edit the file /etc/passwd using vi editor and change the UID of the user "adm" to 0(zero)
now login as user "adm" the user "adm" will be like root

THIS IS NOT A GOOD PRACTICE THOUGH IT WORKS

Thanks for your comments

One more question about sudo.

I find a link about it

Sudoers Manual

Do you have another to talk about it.

All this for security, weakness and strength,etc.


Thanks again for the comments
