Net::Server::Proto::SSUser Contributed Perl DocumentNet::Server::Proto::SSL(3)NAMENet::Server::Proto::SSL - Net::Server SSL protocol.
SYNOPSIS
See Net::Server::Proto.
DESCRIPTION
Experimental. If anybody has any successes or ideas for improvment
under SSL, please email <paul@seamons.com>.
Protocol module for Net::Server. This module implements a secure
socket layer over tcp (also known as SSL). See Net::Server::Proto.
There is a limit inherent from using IO::Socket::SSL, namely that only
one SSL connection can be maintained by Net::Server. However,
Net::Server should also be able to maintain any number of TCP, UDP, or
UNIX connections in addition to the one SSL connection.
Additionally, getline support is very limited and writing directly to
STDOUT will not work. This is entirely dependent upon the
implementation of IO::Socket::SSL. getline may work but the client is
not copied to STDOUT under SSL. It is suggested that clients sysread
and syswrite to the client handle (located in $self->{server}->{client}
or passed to the process_request subroutine as the first argument).
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.
BUGS
Christopher A Bongaarts pointed out that if the SSL negotiation is slow
then the server won't be accepting for that period of time (because the
locking of accept is around both the socket accept and the SSL
negotiation). This means that as it stands now the SSL implementation
is susceptible to DOS attacks. To fix this will require deviding up
the accept call a little bit more finely which may not yet be possible
with IO::Socket::SSL. Any ideas or patches on this bug are welcome.
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.
