[Pdns-users] Open mDNS Servers Report

[Peter van Dijk]

It is likely the report is about UDP, not TCP. Please be aware that UDP 
sockets do not say ‘LISTEN’ in netstat.

If you really can find nothing on that port, and also no iptables 
mappings that might make something available on that port, consider the 
possibility that the report is bogus.

Kind regards,
