Re: telnet to AF_UNIX sockets [PATCH]

[Matt Dillon]

:Because `all  telnet really  does is connect  to sockets'  is patently
:false.  Check out  the nearly 100 RFCs detailing  the TELNET protocol.
:Almost none  of these make much  sense to do over  UNIX domain sockets
:[1].

    Huh?  Oh yah, *that* protocol. Telnet only does that if the server
    is a telnetd.  Otherwise it's just straight character I/O.  Any
    experienced sysad knows this from telneting to the web server or
    smtp server or pop server, etc etc etc.  Being able to telnet to a unix
    domain socket is no different.

    Unix domain sockets are a good test of experience.  They are obscure
    enough that many people don't even realize they exist (and even fewer
    know that you can pass file descriptors over them).   But unix-domain
    sockets are extremely useful in all manner of applications and the
    more sophisticated programmers use them all over the place.  Being able
    to telnet to one is natural.  Over the years I've probably
    written the 'connect to unix domain socket' program 50 times because
    it wasn't standard in a system.  Now it is.  Yahhh.
