can't listen on some ports (5353,5355)

[royharoush]

Hi,

on 2 different kali machines, running as root, i get the following error.

Error starting UDP server on port 5353. Check that you have the necessary permissions (i.e. root), no other servers are running and the correct network interface is set in Responder.conf.
Error starting UDP server on port 5355. Check that you have the necessary permissions (i.e. root), no other servers are running and the correct network interface is set in Responder.conf.

Croot@kali-vm:~/Responder#

i've tried using the built in version and cloning from git.
nothing is actually listening on these ports
