Net::Server::Proto::SSL(3)           User Contributed Perl Documentation          Net::Server::Proto::SSL(3)



NAME
       Net::Server::Proto::SSL - Net::Server SSL protocol.

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

       See Net::Server::Proto.  See Net::Server::Proto::SSLEAY.

           use base qw(Net::Server::HTTP);
           main->run(
               proto => 'ssl',
               SSL_key_file  => "/path/to/my/file.key",
               SSL_cert_file => "/path/to/my/file.crt",
           );


           # OR

           sub SSL_key_file  { "/path/to/my/file.key" }
           sub SSL_cert_file { "/path/to/my/file.crt" }
           main->run(proto = 'ssl');


           # OR

           main->run(
               port => [443, 8443, "80/tcp"],  # bind to two ssl ports and one tcp
               proto => "ssl",       # use ssl as the default
               ipv  => "*",          # bind both IPv4 and IPv6 interfaces
               SSL_key_file  => "/path/to/my/file.key",
               SSL_cert_file => "/path/to/my/file.crt",
           );


           # OR

           main->run(port => [{
               port  => "443",
               proto => "ssl",
               # ipv => 4, # default - only do IPv4
               SSL_key_file  => "/path/to/my/file.key",
               SSL_cert_file => "/path/to/my/file.crt",
           }, {
               port  => "8443",
               proto => "ssl",
               ipv   => "*", # IPv4 and IPv6
               SSL_key_file  => "/path/to/my/file2.key", # separate key
               SSL_cert_file => "/path/to/my/file2.crt", # separate cert

               SSL_foo => 1, # Any key prefixed with SSL_ passed as a port hashref
                             # key/value will automatically be passed to IO::Socket::SSL
           }]);

DESCRIPTION
       Protocol module for Net::Server based on IO::Socket::SSL.  This module implements a secure socket
       layer over tcp (also known as SSL) via the IO::Socket::SSL module.  If this module does not work in
       your situation, please also consider using the SSLEAY protocol (Net::Server::Proto::SSLEAY) which
       interfaces directly with Net::SSLeay.  See Net::Server::Proto.

       If you know that your server will only need IPv4 (which is the default for Net::Server), you can load
       IO::Socket::SSL in inet4 mode which will prevent it from using Socket6 and IO::Socket::INET6 since
       they would represent additional and unsued overhead.

           use IO::Socket::SSL qw(inet4);
           use base qw(Net::Server::Fork);

           __PACKAGE__->run(proto => "ssl");

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

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

LICENCE
       Distributed under the same terms as Net::Server

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