killing spree

[ETfan]

1st post so i need to say "Hello everyone and thanks for a great bot"

I have been using Fritzbots for a while now with no probs and its a great bot and loads of fun.
I host a non-dedicated server on my PC and get friends to join through the internet and everything works great but i would like to add the killingsprees using ETadmin_mod.

Im using Windows and Cygwin and im getting errors when i run the etadmin_mod.sh Saying i need to check my .cfgs.
I think i have got all the paths set up right in the .cfg but one thing im not sure about is :

input_type
Please choose, how you want the commands to be passed to the ET-server Valid options: udp / file input_type

If im just hosting from my home pc do i set it as udp or file?
And whats the diffrence between both of them?
TIA to anyone who can help.
