01 Security

Is port 2165 dangerous?

We have no specific security note for port 2165. 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 2165, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2165'      # process listening on 2165
sudo lsof -nP -i :2165

macOS

sudo lsof -nP -i :2165

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2165 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2165
netstat -ano | findstr :2165

From another machine

nmap -p 2165 -sV <host>
sudo nmap -sU -p 2165 <host>
nc -zv <host> 2165

Block it in the firewall

sudo ufw deny 2165/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2165" -Direction Inbound -LocalPort 2165 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2165 used for?

Port 2165 is assigned by IANA to x-bone-api (X-Bone API).

Is port 2165 TCP or UDP?

Port 2165 is registered for TCP and UDP.

Is it safe to open port 2165?

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 2165 is open?

On Linux run "ss -ltnup 'sport = :2165'", on macOS "lsof -nP -i :2165", and on Windows "netstat -ano | findstr :2165" to see the local process. From another machine, "nmap -p 2165 <host>" shows whether it is reachable.
