Clients must be configured to match, making this a purely internal or testing configuration. A tcpdump capture on a Samba server using port 170 would show: smbd 170

But deep within the fabric of enterprise IT departments and legacy infrastructure, a quieter, often misunderstood port hums along: Port 170 . sudo ss -ulnp | grep :170 Expected output:
