01 Security

Is port 7170 dangerous?

We have no specific security note for port 7170. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 7170, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7170'      # process listening on 7170
sudo lsof -nP -i :7170

macOS

sudo lsof -nP -i :7170

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7170 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7170
netstat -ano | findstr :7170

From another machine

nmap -p 7170 -sV <host>
sudo nmap -sU -p 7170 <host>
nc -zv <host> 7170

Block it in the firewall

sudo ufw deny 7170/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7170" -Direction Inbound -LocalPort 7170 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7170 used for?

Port 7170 is assigned by IANA to nsrp (Adaptive Name/Service Resolution).

Is port 7170 TCP or UDP?

Port 7170 is registered for TCP and UDP.

Is it safe to open port 7170?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 7170 is open?

On Linux run "ss -ltnup 'sport = :7170'", on macOS "lsof -nP -i :7170", and on Windows "netstat -ano | findstr :7170" to see the local process. From another machine, "nmap -p 7170 <host>" shows whether it is reachable.
