If the socket closes at the other end (e.g server shuts down), then the while loop will end and the child will exit. So you may want to wrap your socket read loop within another loop that will open the socket e.g

while($some_guaranteed_condition) {
    my $socket = IO::Socket::INET->new( ... );
    while($line = <$socket>) {
        ...
    }
    $socket->shutdown(2);
}

This should loop until the silicon wears out, but you'll probably want to put in some graceful shutdown mechanism within the first loop (and the second loop perhaps?). I'd also check out CPAN for some daemon type modules (e.g Net::Daemon and Net::TCP::Server).

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
• Want more info? How to link or How to display code and escape characters are good places to start.
