in thread Religion in the Monastery.

I've done my few years in programming, still no belief in gods. However, I do now believe in Pure Evil. It is the least-complex explanation I can think of for that class of user that ALWAYS asks the same questions, NEVER bothers to read the manual, and INSISTS on me dropping everything to help them with exactly the same problem I helped them with last week.

[oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
[tye]: I just daemonized and getlogin() still knew who I had been.
[tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
[Corion]: tye: That's really interesting, but maybe it is because getlogin() returns the name, or the uid, so if that user has been replaced by another user with the same uid in the meantime, that's no problem to the system...
[davido]: or on ubuntu /var/run/utmp
[Corion]: Otherwise, I would imagine that a user with a process still alive would lock that information in memory.
[davido]: so last -f /var/run/utmp on ubuntu provides similar (though more verbose) info
[oiskuu]: glibc getlogin just does ttyname() and falls back on getutline(); it's not security related at all. (reminds me of sendmail and remote finger services of the naive early spam era)
[Corion]: But yes, "who started this process" is interesting information :)
[tye]: no, I really believe that "login user" was added as a fundamental bit of info about each process in order to enhance the usefulness of auditing
