Responder is an LLMNR, NBT-NS and MDNS poisoner. It will answer to specific NBT-NS (NetBIOS Name Service) queries based on their name suffix (see: http://support.microsoft.com/kb/163409).\n\
By default, the tool will only answer to File Server Service request, which is for SMB.\n\n\
The concept behind this is to target our answers, and be stealthier on the network. This also helps to ensure that we don't break legitimate NBT-NS behavior.\n\n\
All activity will be logged to Responder-Session.log\n\
Analyze mode will be logged to Analyze-Session.log\n\
Poisoning will be logged to Poisoners-Session.log\n\n\
All hashes are dumped an unique file John Jumbo compliant, using this format:\n\
(MODULE_NAME)-(HASH_TYPE)-(CLIENT_IP).txt\n\n\
