AIX

What alpha*test says is correct, but: Unix identifies users by looking up their UID/GID in /etc/passwd. Whoever comes first there will be shown as owner of files/directories, because the ownership is established not by storing the name but by storing the UID in the directories structure. Hence:

Code:

$ su - root2
# id 
uid=0(root) gid=0(system) groups=2(bin),3(sys),7(security),8(cron),10(audit),11(lp)

# touch a_file
# ls -l
total 3496
-rwxr-x---   1 root     system            0 Jan 21 2006  file_created_by_root
-rwxr-x---   2 root     system            0 Jan 21 2006  a_file

#

You see, even when yo switch to root2 you look like you are root.

thank you for your help

Hello,

This configuration works fine but there is another problem though. If you do a ssh session to another server, the system will simply log you on as 'root' and not as the new user with root previleges. The new user however does exist on the other server and also has root previleges and the necessary SSH keys. Any ideas?


Kind regards,
Karel

I think this goes back to what was said earlier. UNIX identifies the user by the UID, not the name. So if root2 is operating under UID 0, then it will still be seen as 'root' by the receiving system (the one you SSH to).
