Greetings monks;
I'm trying to get a non-forking perl TCP server (at its simplest) to listen to multiple local ports bound to the same address and am having a time making it work. What I'm doing appears logical... but just doesn't want to do its thing.
I use IO::Select to watch the first port, and figured it'd be as simple as add()ing another server handle to the Select handle's list... apparently not.
The below code produces a working server on port 5000, however when I connect to port 5050 the script terminates with a 'Broken pipe' error, closing the telnet connection rather impolitely.
my $server = IO::Socket::INET->new(LocalPort => 5000,
Listen => 10,
Reuse => 1)
or die "Can't make server socket: $@\n";
my $serverB = IO::Socket::INET->new(LocalPort => 5050,
Listen => 10,
Reuse => 1)
or die "Can't make server socketB: $@\n";
my $select = IO::Select->new(($server, $serverB));
while (1) {
foreach my $client ($select->can_read(1)) {
if ($client == $server) {
$client = $server->accept();
$select->add($client);
print $client "Howdy\n";
} else {
print $client "G'bye\n";
$select->remove($client);
close($client);
}
}
}
If I switch the Select->new statement, I get the same results, so I know its not in the way I add the handle to the Select.
ie:
my $select = IO::Select->new();
$select->add($server); $select->add($serverB);
What fundamental fact am I missing here that prevents this from working like I want it to? (Sounds suspiciously like "Do what I
want, not what I
say")
Thanks all;
JP,

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>

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).
