This is probably no help whatsoever, but your code works just fine for me. RedHat 9, perl 5.8.0
Perhaps if recv() is blocking you should use IO::Select? (rampant straw grasping here :)
#!/usr/bin/perl
use strict;
use warnings;
use IO::Socket::INET;
use IO::Select;
my $sel = IO::Select->new;
my $port = getservbyname 'bootps', 'udp';
my $socket = IO::Socket::INET -> new (LocalPort => $port,
Broadcast => 1,
Proto => 'udp')
or die "Failed to bind to socket: $@";
$sel->add($socket);
my $n = 10;
my $mess;
while (1) {
my @r = $sel->can_read($n);
unless (@r) { print "Nothing after $n seconds\n"; next; }
$socket -> recv ($mess, 1024);
print "Saw a bootp request.\n";
}
__END__

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).
