tcptunnel

I recently had the chance to test out tcptunnel, a highly versatile TCP tunnel software. This tunnel uses a firewall or proxy, and can even redirect TCP connections to other ports or machines. One of its key features is its ability to perform in-place debugging of TCP connections and packet sniffing, allowing for a secure and reliable experience.

The tcptunnel listens on a local port, and connects the other end of the tunnel automatically. Without a proxy specified, it connects the other end to the desired server port. If a proxy is specified, tcptunnel connects to the server port and directs the proxy to telnet to the desired server. Once both ends of the tunnel are connected, data can be passed between them safely and securely.

Overall, I found tcptunnel to be a simple and efficient solution for TCP tunneling needs. Its versatile features make it a great choice for anyone in need of a reliable and secure connection. Whether you're looking to tunnel through a firewall or proxy, redirect TCP connections, or perform in-place debugging, tcptunnel is an excellent option to consider.
