IO::Socket::INET's timeout method (or the Timeout hash-param to the constructor) won't do what you want here. That timeout value corresponds to how long the socket should wait for acknowledgment from the peer when it has sent data (or is trying to connect).
You definitely do need some sort of "global timer". You're forking, so it's probably as simple as:
- recording the PID of the child in a hash, along with the start time
- noting when the child process should no longer be around,
- sending the KILL signal to the child process.
To set up the timer, you'll either need to use alarm, or switch to a non-blocking form of $server->accept.
I recommend putting the listening socket into an IO::Select object, then adding calls to Timer::HiRes::usleep in your while loop.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
