thanks for this.

sorry, 1 more question - when i do nc with the -u option, it keeps running and doesn't give me the next prompt until i press ctrl-c. is there a way to stop this from happening? even if i put it in a script with exit 0 at the end this doesnt help.

Net::Proxy::Connector::ssl(3pm) 			User Contributed Perl Documentation			   Net::Proxy::Connector::ssl(3pm)

NAME
Net::Proxy::Connector::ssl - SSL Net::Proxy connector DESCRIPTION
"Net::Proxy::Connecter::ssl" is a "Net::Proxy::Connector" that can manage SSL connections (thanks to "IO::Socket::SSL"). By default, this connector creates SSL sockets. You will need to subclass it to create "smarter" connectors than can upgrade their connections to SSL. In addition to the options listed below, this connector accepts all "SSL_..." options to "IO::Socket::SSL". They are transparently passed through to the appropriate "IO::Socket::SSL" methods when needed. CONNECTOR OPTIONS
The connector accept the following options: "in" o host The listening address. If not given, the default is "localhost". o port The listening port. o start_cleartext If true, the connection will start in cleartext. It is possible to upgrade a socket to using SSL with the "upgrade_SSL()" method. "out" o host The listening address. If not given, the default is "localhost". o port The listening port. o start_cleartext If true, the connection will start in cleartext. It is possible to upgrade a socket to using SSL with the "upgrade_SSL()" method. METHODS
The "Net::Proxy::Connector::ssl" connector has an extra method: upgrade_SSL( $sock ) This method will upgrade a cleartext socket to SSL. If the socket is already in SSL, it will "carp()". CREATING A SELF-SIGNED CERTIFICATE I tend to forget this information, and the openssl documentation doesn't make this any clearer, so here are the most basic commands needed to create your own self-signed certificate (courtesy David Morel): $ openssl genrsa -out key.pem 1024 $ openssl req -new -key key.pem -x509 -out cert.pem -days 365 A certificate is required is you want to run a SSL server or a proxy with a "Net::Proxy::Connector::ssl" as its "in" connector. Once the key and certificate have been created, you can use them in your parameter list to "Net::Proxy->new()" (they are passed through to "IO::Socket::SSL"): Net::Proxy->new( { in => { host => '0.0.0.0', port => 443, SSL_key_file => 'key.pem', SSL_cert_file => 'cert.pem', }, out => { type => 'tcp', port => '80' } } ); AUTHOR
