01 Security

Is port 3169 dangerous?

We have no specific security note for port 3169. 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 3169, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3169'      # process listening on 3169
sudo lsof -nP -i :3169

macOS

sudo lsof -nP -i :3169

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3169 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3169
netstat -ano | findstr :3169

From another machine

nmap -p 3169 -sV <host>
sudo nmap -sU -p 3169 <host>
nc -zv <host> 3169

Block it in the firewall

sudo ufw deny 3169/tcp                                         # Linux (ufw)

04 FAQ
What is port 3169 used for?

Port 3169 is assigned by IANA to serverview-as (SERVERVIEW-AS).

Is port 3169 TCP or UDP?

Port 3169 is registered for TCP and UDP.

Is it safe to open port 3169?

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 3169 is open?

On Linux run "ss -ltnup 'sport = :3169'", on macOS "lsof -nP -i :3169", and on Windows "netstat -ano | findstr :3169" to see the local process. From another machine, "nmap -p 3169 <host>" shows whether it is reachable.
