Using ncat as a Telnet Client
There are apparently multiple applications for netcat. It can do a rudimentary port scan. It can do file transfer. It can also act as a backdoor. Originally it was developed by "Hobbit" in 1995 for UNIX. There is a more modern implementation called ncat. Ncat adds things like support for IPv6 and SSL.
I downloaded ncat. Initially I could not figure out how to use it. Then I figured I would test it out as a client for telnet. Had to install a telnet server on my machine first. Ended up installing the free KpyM Telnet Server. Here is a hint for KpyM: they give you a registration key for free to remove the nag screen.
Initially I got ncat to connect to my telnet server. But it was displaying a bunch of strange characters. Was not sure if this was an ncat issue or a telnet server issue. So I got another dedicated telnet client installed. That client worked fine with my telnet server. Damn. I guess ncat will take some getting used to. Maybe a bunch of configuration to do.
So far I have not found much use for this ncat. Maybe as I get into network programming some more, I will find the need.
