Reset connections after MITM

[Mr-Protocol]

Say I have a MITM using arpsoof. Is there a tool in backtrack that will reset the connections on a host so that they must reinput their login credentials for websites/Domain/FTP/etc. Or will the connection essentially reset when the MITM is put into place? My forensic lab is currently occupied by classes, so I cannot test this.

Just do at the command prompt:

tcpkill -i [interface] host [IP]

And it shall reset all connections coming from that IP. It's a tool of the dsniff package.

Cool, thanks. I figured there was a tool but I wasn't sure what one of the many BackTrack 4 has to offer was the one I wanted.
