Ident server that sends the string found in
/usr/local/share/cidentd/$username as
a response.

This is a very early incarnation; so bear with;
Only the first line of $PREFIX/share/cidentd/$username
is used, and to be useful must comply with rfc-1413;
namely it must be of the form "OS :whatever_username_you_desire".

Probably not safe; most notably the owner of the
file is not checked against the owener of the socket.

Probably will break; under heavy load (~10,000 connections)
there are segfaults within subthreads and resultant memory leaks.
Not many, but be aware of them.

Nothing is configurable yet; see the source if you want
to change something.  In order to bind to port 113 you
must run it as root.  Root privilages are dropped after
binding by changing to user and group 65533.

stderr is left open for error reporting.  A log file
will appear in the next version.  If this bothers you,
redirect to /dev/null.

A note on coding style.  Yes, mine is most likely bad;
I use "char* str" instead of "char *str"; it makes
sense to me.  Braces go on the same line as the
associated construct: "int main() {", "if() {", and
"struct thingy {" come to mind.  I use whatever
parenthetical space makes it easier for me to grasp at
a glance; YMMV.  I do make an effort to create
meaningful variable names; if two names refer to the
same variable but in a different way, Hungarian
notation may appear.  I use KDevelop.

One final thing; I am not sure what to distribute as
part of a distribution, so i incude just about
everything (after a distclean, automake and autoconf).
The standard Linux spell "./configure; make; make
install" applies.

-t.
