You never had the opportunity to accept any connection from the client side. Add $sock to IO::Select is no good, as it is not an "active channel" yet. Add the accept(), plus fix some minor syntax stuff, your code works.

use strict; use warnings; use IO::Socket; use IO::Select; my $sock = IO::Socket::INET->new( Proto=>"tcp", LocalHost=>"localhost", Listen=>16, Reuse=>1, LocalPort=>3000 ) or die("Could not create socket!\n") +; my $connection = $sock->accept(); my $readSet = new IO::Select(); $readSet->add($connection); while(1) { my @rhSet = IO::Select->select($readSet, undef, undef, 0); foreach my $rh (@{$rhSet[0]}) { my $buf=<$rh>; if($buf) { printf "$buf"; } else { $readSet->remove($rh); close($rh); } } }

Client side test code:

use IO::Socket; my $sock = IO::Socket::INET->new( Proto=>"tcp", PeerHost=>"localhost", PeerPort=>3000 ) or die("Could not create socket!\n") +; print $sock "abcd\n";

Well, I leave it to you to add back the code to accept further connections.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
