Kwakd is a very small foot print web server written in C that serves blank html pages for any request. The request can be arbitrary, may even be invalid, but only its first line will be read and the response will be the same: a blank page consisting of " ". It is quite easy to change the response to whatever you like though. Kwakd can be handy if you want to intercept traffic from your client (web browser for example) to annoying sites and direct all such traffic to your local machine. By default kwakd uses port 8000, but this can be changed in the provided initscript by changing the port option. See /etc/rd.c/rc.kwakd
