Top Forums UNIX for Advanced & Expert Users How to get a login name of a person who used 'su' and act with different user-name? Post 302285840 by alex_5161 on Monday 9th of February 2009 08:34:21 PM

fimbo - or I could not understand what you advice, or I did not explain well what I need to have.
You are right, ps -ef could drive me to original process - completely understand PID and PPID relation.

But in our sistem the 'su' command is not visable.
So, how I can know who is under the 'support' login?

One person start a background script and closed the session.

After some period of time script need to display a message, but original session is not available.
But it must to be someone else under the same 'support' id, logged with 'su'

Using the 'write' command is not possible - the 'write' do not see the person after the 'su' - it sais: the 'support' person is not logged.
But I see many processes of the 'support' person and can't write a message to that user.

The 'ptree' is available on this system, but there is no 'su', also
See example.
I have logged in the system with my log ID, and 'su' for the same id (I do not have any other id available).
I have start 'tail -f ..' to recognize process
See the part of 'ptree':
Code:
            17175 more -s /tmp/mpwMaqGH
  18599 in.telnetd
    18602 -ksh
      18662 bash
        18727 ksh
          18766 bash
            18859 tail -f tst.sh
746   /usr/lib/nfs/statd

...
I think the ptree is usefull to see, but to follow to the originating PID from script is not comportable.
