Firewall complaining about IPC::Run

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

My firewall was complaining that IPC::Run wanted to act like a server, I tracked it down to C:\Perl\site\lib\IPC\Run\Win32IO.pm

unless ( bind $listener, sockaddr_in( $port, INADDR_ANY ) ) {
[download]

the fix was to change it to

unless ( bind $listener, sockaddr_in( $port, $loopback) ) {
[download]

If you wish to submit a bug report, this isn't the place. Visit the module's page on CPAN and follow the link named "Report a bug".	[reply]

Indeed. But why does IPC::Run::Win32IO try to open a socket accepting connections from everywhere? For IPC on one machine, a loopback connection should be sufficient. Everything else could open security holes. Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply]

Because INADDR_ANY means just that: everywhere.	[reply]

...and the question you wish to put to the monks is ??? All I see is a potential problem and a resolution to said potential problem ... A user level that continues to overstate my experience :-))	[reply]

I found another in Test::WWW::Mechanize Test-WWW-Mechanize-1.24\t\TestServer.pm `sub new { my $class = shift; die 'An instance of TestServer has already been started.' if $pid; # XXX This should really be a random port. $class = $class->SUPER::new(13432, @_); $class->host('127.0.0.1'); return $class; }` [download]	[reply] [d/l]
