Hmmm. Excellent points to consider. Thanks. Sorry I couldn't find this link earlier.

But how do you get around the typical username/password authentication to log into one of your accounts somewhere? Wouldn't they need to be ADA compliant also? Or does a good text-to-speech reader read the text and prompt the individual to type their info?

    I have been seing services adopting the practice of offering sound files as a verification vehicle for those who can't see the image.

    I don't know of a CPAN module that implements this so far, though, so you'd have to roll your own on this one.

      Which is, of course, equally problematical for people with hearing disabilities - often the very same people who have visual disabilities :-)

    If you want to make sure you'll be ADA compliant, there's some information on creating an audio Turing test here. I responded to that thread at the bottom, but I'm not familiar with that message board and I might try creating a new thread that gets pushed to the top of the list where someone might actually see it.

    UPDATE: See the replies I got here.

[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.
[tye]: for example, read https://unix. questions/146138/ loginuid-should-be -allowed-to-change -or-not-mutable-or -not
[tye]: I'm not using SELinux and it certainly appears to disagree with you. shrug
[tye]: Since you brought up /proc, oiskuu, I didn't see you respond to my suggestion of 'loginuid'. Does your /proc not have such?
