To add to the above, the equivalent of listening using netcat (netcat -l) to push data is
1: #!/usr/bin/perl -w
2: # No nc -l on SunOS 5.8 DMZed host to transfer data out.
3: # Perl to the rescue:
4:
5: use strict;
6: use IO::Socket;
7:
8: select IO::Socket::INET->new(LocalPort=>(shift||2222), Listen=>1
+)->accept;
9:
10: print
11: for <>;
12:
13: __END__
14: # or, as a oneliner:
15: perl -MIO::Socket -pe 'BEGIN{select IO::Socket::INET->new(LocalP
+ort=>(shift||2222), Listen=>1)->accept;}'

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).

or How to display code and escape characters
are good places to start.
