01 Security

Is port 2160 dangerous?

We have no specific security note for port 2160. 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 2160, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2160'      # process listening on 2160
sudo lsof -nP -i :2160

macOS

sudo lsof -nP -i :2160

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2160 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2160
netstat -ano | findstr :2160

From another machine

nmap -p 2160 -sV <host>
sudo nmap -sU -p 2160 <host>
nc -zv <host> 2160

Block it in the firewall

sudo ufw deny 2160/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2160" -Direction Inbound -LocalPort 2160 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2160 used for?

Port 2160 is assigned by IANA to apc-2160 (APC 2160).

Is port 2160 TCP or UDP?

Port 2160 is registered for TCP and UDP.

Is it safe to open port 2160?

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 2160 is open?

On Linux run "ss -ltnup 'sport = :2160'", on macOS "lsof -nP -i :2160", and on Windows "netstat -ano | findstr :2160" to see the local process. From another machine, "nmap -p 2160 <host>" shows whether it is reachable.
