Projects / shd-tcp-tools


shd-tcp-tools is a set of TCP network tools that supports port forwarding, network load balancing, rate limiting, and running servers behind firewalls. tcp-pf, listentwo, and connecttwo are port forwarding tools. tcppipe is a one-directional TCP pipe that can be used as a substitute for one-directional netcat transfers, but with load balancing and rate control support. tcp-pf can be used to forward a port from one host to another with load balancing and rate control support. network load balancing scheme means using an interface or destination host based on past transfer history. The listentwo and connecttwo tools can be used to run servers inside firewalled networks through third party TCP proxies.
