BUGS/PROBLEMS - -NOTES - -THANKS - -================================================================================ - -===== -INTRO -===== - -Active port forwarder is a software tool for secure port forwarding. -It uses ssl to increase security of communication between a server and a client. -Originally, it was developed to forward data point to point. However, the need -for bypassing firewalls in order to connect to internally located computers -influenced the further development of the project. - -AF is dedicated for people, who don't have an external ip number and want to -make some services available across the net. - -Moreover, zlib is used to compress the transferred data. - -Using one, permanent data/control channel with flow control / packet buffering -provides good performance and reasonably small latency. - -Multiple clients allow to create more sophisticated tunneling scheme. - -================================================================================ - -=============== -1.

Let's suppose we want to create a http server -on our computer and we are behind a masquerade or a firewall: - -1) We have to find some machine on the net with an external ip and a shell - account. - -2) Use "make" to compile everything on that machine. (you can freely remove the - afclient and client.rsa files) - -3) You can edit the config file or just type from the console (to use the config - type -f ) : - $ ./afserver - This will work, if you want to use default values: - - hostname will be taken from hostname function (it would be ideally, if - there is appropriate registration in /etc/hosts) - - server will be listening for users on port 50127 - - server will be listening for client on port 50126 - - server will be for maximum 5 users - - server will forward tcp packets - - there will be no logging and no verbose messages - - there will be no password identification - - ip protocol family will be unspecified - -4) We use "make" on our machine (we can delete everything apart from afclient - and client.rsa) - -5) We are typing from the console: - $ ./afclient -n -p 80 - Where is a string like : 'bastion.univ.gda.pl' or - '153.19.7.200' - -6) We can now enter with a web-browser to: :50127 and we - will enter to our computer in the fact. - - 3.2 reverse udp mode - -------------------- - - local network |FireWall| Internet - || (udp) - || User 1-------AF Client - || /(tcp) - AF Client <---Encrypted/Compressed channel---> AF Server - / || | - /(udp) || (tcp)| - / || / - Game server || AF Client-------User 2 - || (udp) - - -Let's see how to use af to forward udp packets.
