Is port 3107 dangerous?

We have no specific security note for port 3107. 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 3107, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3107'      # process listening on 3107
sudo lsof -nP -i :3107

macOS

sudo lsof -nP -i :3107

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3107 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3107
netstat -ano | findstr :3107

From another machine

nmap -p 3107 -sV <host>
sudo nmap -sU -p 3107 <host>
nc -zv <host> 3107

Block it in the firewall

sudo ufw deny 3107/tcp                                         # Linux (ufw)

04 FAQ
What is port 3107 used for?

Port 3107 is assigned by IANA to business (Business protocol).

Is port 3107 TCP or UDP?

Port 3107 is registered for TCP and UDP.

Is it safe to open port 3107?

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 3107 is open?

On Linux run "ss -ltnup 'sport = :3107'", on macOS "lsof -nP -i :3107", and on Windows "netstat -ano | findstr :3107" to see the local process. From another machine, "nmap -p 3107 <host>" shows whether it is reachable.
