Free netcat windows

The tool is "old" and simple, but still is actual and useful. Thanks to developer! I have been using netcat for ages and works great in IPv4 environments. Do you guys use it also in IPv6 networks? I know about the v6 version nc6 but I'm not sure how stable it is in IPv6 cases.

I have seen some people having issues with nc6. The venerable nc relives as ncat and this is a serious update. When it gets connected to by a client it will spawn a shell cmd. The -t option tells Netcat to handle any telnet negotiation the client might expect. This will allow you to telnet to the machine you have Netcat listening on and get a cmd. You could just as well use Netcat instead of telnet: nc xxx.

There is no authentication on the listening side so be a bit careful here. The shell is running with the permissions of the process that started Netcat so be very careful.

If you were to use the AT program to schedule Netcat to run listening on a port with the -e cmd. The beauty of Netcat really shines when you realize that you can get it listening on ANY port doing the same thing. Do a little exploring and see if the firewall you may be behind lets port 53 through.

Run Netcat listening behind the firewall on port Use 'exit' at the command prompt for a clean disconnect. The -L note the capital L option will restart Netcat with the same command line when the connection is terminated. This way you can connect over and over to the same Netcat process. A new feature for the NT version is the -d or detach from console flag.

This will let Netcat run without an ugly console window cluttering up the screen or showing up in the task list. Unlike Unix, NT does not seem to have any security around which ports that user programs are allowed to bind to. You will need to bind "in front of" some services that may already be listening on those ports. You need to bind to a specific source address one of the IP addresses of the machine to accomplish this.

This is done with the Netcat -s option: nc -v -L -e cmd. You have effectively shut off file sharing on this machine by the way.

You have done this with just user privileges to boot. One is the -w or timeout option. This works for final net reads but not for connections. Another problem is using the -e option in UDP mode. You may find that some of the features work on Windows Most of the listening features will not work on Windows 95 however. These will be fixed in a later release. Netcat is distributed with full source code so that people can build upon this work.
