Closing IO::Socket::INET

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

I am opening a listener with:

my $lis = IO::Socket::INET->new(LocalPort => $portnumber,
                                Listen    => 10 );
[download]

When i restart it, I get the "Can't make server socket: IO::Socket::INET: Address already in use" message. So i tried closeing the socket with:

$lis->close();
[download]

But am still getting the message. How do I close it off so that I don't get the already in use message?

Add `ReuseAddr => 1` to your param list. The OS is trying to help you by not letting any lingering packets in a connection accidently go to a new process. If you are sure that this will never happen (or don't care), you can tell the kernel that you'll live dangerously by permitting quick re-use of the same port number. -- Randal L.

You can use the `Reuse` argument in the `IO::Socket::INET` constructor: `my $lis = IO::Socket::INET->new(LocalPort => $portnumber, Reuse => 1, Listen => 10 );` [download] Doing this will set the `SO_REUSEADDR` option on the new socket. Without it, you'll have to wait a few minutes between exiting & restarting. -- vek --	[reply] [d/l] [select]
