[WSL]: Error starting UDP/TCP server on port

[ph-hitachi]

Hi i'm encountering error on wsl while using responder is there any way to change the port ?

$ sudo ss --tcp --udp --listen --numeric --process | grep 53
udp   UNCONN 0      0      10.255.255.254:53         0.0.0.0:*
tcp   LISTEN 0      1000   10.255.255.254:53         0.0.0.0:*

$ sudo responder -I tun0

@ph-hitachi Why don't you just close/kill the other process listening that port?

@ph-hitachi: Most modern distros come with a caching DNS server listening on localhost:53. You need to disable that service and replace it with /etc/resolv.conf if you want to use anything else that listens on 53.
