NAME

6       Net::Server::Proto::SSL - Net::Server SSL protocol.
7

SYNOPSIS

9       Until this release, it was preferable to use the
10       Net::Server::Proto::SSLEAY module.  Recent versions include code that
11       overcomes original limitations.

DESCRIPTION

61       Protocol module for Net::Server based on IO::Socket::SSL.  This module
62       implements a secure socket layer over tcp (also known as SSL) via the
63       IO::Socket::SSL module.  If this module does not work in your
64       situation, please also consider using the SSLEAY protocol
65       (Net::Server::Proto::SSLEAY) which interfaces directly with
66       Net::SSLeay.  See Net::Server::Proto.
67
68       If you know that your server will only need IPv4 (which is the default
69       for Net::Server), you can load IO::Socket::SSL in inet4 mode which will
70       prevent it from using Socket6, IO::Socket::IP, or IO::Socket::INET6
71       since they would represent additional and unused overhead.
72
73           use IO::Socket::SSL qw(inet4);
74           use base qw(Net::Server::Fork);
75
76           __PACKAGE__->run(proto => "ssl");
77

PARAMETERS

79       In addition to the normal Net::Server parameters, any of the SSL
80       parameters from IO::Socket::SSL may also be specified.  See
81       IO::Socket::SSL for information on setting this up.  All arguments
82       prefixed with SSL_ will be passed to the IO::Socket::SSL->configure
83       method.
84

BUGS

86       Until version Net::Server version 2, Net::Server::Proto::SSL used the
87       default IO::Socket::SSL::accept method.  This old approach introduces a
88       DDOS vulnerability into the server, where the socket is accepted, but
89       the parent server then has to block until the client negotiates the SSL
90       connection.  This has now been overcome by overriding the accept method
91       and accepting the SSL negotiation after the parent socket has had the
92       chance to go back to listening.

THANKS

98       Thanks to Vadim for pointing out the IO::Socket::SSL accept was
99       returning objects blessed into the wrong class.
