Let's suppose we want to create http server on +our computer and we are behind masquerade or firewall: + +1) We have to find some machine on the net with external ip and shell account. + +2) Use make to compile everything on that machine. (you can freely remove afclient + and client.rsa files) + +3) You can edit config file or just type from the console: (to use config type -f <cfgfile>) + $ ./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 + +4) We use make on our machine (we can delete everything apart afclient and client.rsa) + +5) We are typing from the console: + $ ./afclient -n <name of the server> -p 80 + Where <name of the server> is a string like : 'bastion.univ.gda.pl' or '153.19.7.200' + +6) We can now enter with webbrowser to : <name of the server>:50127 and we will enter to our + computer in the fact. + +EXAMPLE 2: + +Let's see how to use af to forward udp packets. Suppose we want to create a game server +on our computer (udp port 27960 on our machine): + +1) - 4) is the same like in example 1. (but we add option: -t udp) + +5) We are typing from the console: + $ ./afclient -u -n <name of the server> -p 27960 + Where <name of the server> is a name (or ip) of a host where our server is running. + +6) Connecting to our game is more complicated. User must use afclient to do this. + He has to specify server he is connecting to and port which his program will be listening on: + $ ./afclient -U -d <hostname> -p <portnum> -n <name of the server> -m <server port> + Where <hostname> is name of user machine (who wants to connect to our game). <portnum> + is a port he will be connecting to. <name of the server> is a name of a host where our server + is running. <server port> is a port on which server is listening for users. + In order to connect to our game, user have to connect to <hostname>:<portnum>. + + +Active port forwarder is still under development, so please sent me any comments, bugs notices +and suggestions about it to jeremian@poczta.fm + + +And thanks for using this software! + +LICENSE +------- + + Active Port Forwarder is distributed under the terms of the GNU General Public License + v2.0 and is copyright (c) 2003 jeremian <jeremian [at] poczta.fm>. + See the file COPYING for details. + |
