Just cloned the repo now and noticed that even though after providing --filter-pipe-name, it scans all of them:

[p0dalirius]

Well yes, if you have Responder running and using Coercer in scan mode it cannot work. Since Responder is listenning on port 445 to receive incomming SMB authentications and Coercer will do the same.

In scan mode you need to be able to listen on the 445 port on your machine
