    [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
    [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().
