chownat Description

Open source tool for communication between two peers behind two separate NATs with NO port forwarding and NO DMZ chownat is a command line and open source tool which allows two peers behind two separate NATs with NO port forwarding and NO DMZ to communicate with each other. More importantly, it opens up a tunnel between the two machines so one peer can access a service, such as a web server, on the other machine which is also behind a NAT. There is NO middle man, NO proxy, NO 3rd party, and the application runs as an unprivileged user on both ends.How to run: Open a Terminal window, go to the chownat's folder and run the following commands from the command line:sudo cpan Digest::MD4perl chownat.pl-v0.08b What's New in This Release: · sequencing in this version has been improved to be able to quickly transfer lots of data without error (tested 89mb file over scp over chownat) · auto-installation of required modules many improvements by Matthew Balman including: · Command numbers passed as single binary byte instead of 2 chars · Keepalives assigned command# 0 and also include $expected · Increased message # max to be 65535 instead of 255 · Message resend code fixed/optimized · Connect/Disconnect code fixed/optimized · Larger avg. packet sizes · Added command line options for adding digest checking · Added command line option for compression LZV (very fast) · Removed use of "select(undef, undef, undef, 5);"
