Is there a Linux tunable to reduce the amount of time a socket waits before considering the remote side dead?
Its the same senario when you try to telnet to a dead machine, telnet sits and waits for ~30seconds, before the socket timer expires and cancels the request. (5 Replies)

Hi all,
On the server side, one socket is used for listening, the others are used for communicating with the client.

If either can be set, what's the different?
Again, what's the different if set option... (1 Reply)

Paranoid::Network::Socket(3pm) User Contributed Perl Documentation Paranoid::Network::Socket(3pm)
NAME
Paranoid::Network::Socket - Socket wrapper for seemless IPv6 support
VERSION
$Id: Socket.pm,v 0.3 2012/05/29 21:38:37 acorliss Exp $
SYNOPSIS
# use Socket; # no longer needed
use Paranoid::Network::Socket;
use Paranoid::Network::Socket qw(:crlf);
$ipv6_enabled = has_ipv6();
DESCRIPTION
This module is a wrapper for Socket(3) and Socket6(3), and is meant to be used in lieu of using those packages directly. Doing so removes
any of the version dependent support issues on Perl and its bundled Socket(3) where IPv6 is concerned.
Starting in Perl 5.12 the beginnings of IPv6 support emerged in the bundled Socket(3) module, but full IPv6 support didn't arrive until
5.14. Prior versions of Perl required the use of the external Socket6(3) module (available on CPAN).
With this module IPv6 support, if available, is brought in automatically at runtime, regardless of where that support is provided. It also
makes a default export of inet_pton and inet_ntop, something that Socket(3) only does on request.
Finally, this module provides a has_ipv6 function which will return whether your Perl has full IPv6 support. Full support is determined by
the presence of sockaddr_in6.
All of the regular tag sets provided by either Socket modules are supported by this module.
SUBROUTINES
/METHODS
has_ipv6
$ipv6_enabled = has_ipv6();
Returns a boolean value denoting whether or not this module has full IPv6 support.
DEPENDENCIES
o Socket
o Socket6 (optional)
