What is AckCmd? 

AckCmd is a client/server combination for Windows 2000 that lets you open
a remote Command Prompt to another system (running the server part of AckCmd).
It communicates using only TCP ACK segments.
This way the client component is able to directly contact the
server component through a firewall in some cases

How do I use this tool? 

Download the zip file and extract the client component (ackcmdc.exe)
and the server component (ackcmds.exe).
The server component has to be executed on the target system.
Then run the client component with the target IP supplied as an argument.
Now you have a remote Command Prompt. 

Which OS's are supported? 

Windows 2000. 

WARNING! 

Running the AckCmd server part will create a backdoor into your computer!
