Good point. But the reaper has POSITIVE XP. Hmm. Maybe people are voting ++ on the fact it's been reaped.

Hey, if the reaper got XP depending on the rep of the node. Ya know, a -18 rep node would get it 18 XP (or 18 chances for XP, just like everyone else). Then we'd see who could advance quicker - a good monk or all the bad monks together. 8) That'll even give merlyn a run for his money.

[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
[Corion]: Ah - if that information is saved in a file, then you could theoretically spam that file and confuse getlogin(). So, don't use it for authentication :)
[tye]: that is what getlogin() certainly *used* to do. I don't believe that is what it certainly should do.
[davido]: /var/run/utmp is 664 i think.
[tye]: Note that my "man getlogin" says that it uses stdin when it should use /dev/tty (calling a glibc bug). But that does not appear to be the case when I test it. But maybe Perl's getlogin() is not using glibc's getlogin().
[oiskuu]: well, run a strace and see what the getlogin does for you.... As I said. SELinux probably has those security labels. But not regular linux.
