Is port 1707 dangerous?

We have no specific security note for port 1707. 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 1707, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1707'      # process listening on 1707
sudo lsof -nP -i :1707

macOS

sudo lsof -nP -i :1707

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1707 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1707
netstat -ano | findstr :1707

From another machine

nmap -p 1707 -sV <host>
sudo nmap -sU -p 1707 <host>
nc -zv <host> 1707

Block it in the firewall

sudo ufw deny 1707/tcp                                         # Linux (ufw)

04 FAQ
What is port 1707 used for?

Port 1707 is assigned by IANA to vdmplay (vdmplay).

Is port 1707 TCP or UDP?

Port 1707 is registered for TCP and UDP.

Is it safe to open port 1707?

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 1707 is open?

On Linux run "ss -ltnup 'sport = :1707'", on macOS "lsof -nP -i :1707", and on Windows "netstat -ano | findstr :1707" to see the local process. From another machine, "nmap -p 1707 <host>" shows whether it is reachable.
