Is port 2318 dangerous?

We have no specific security note for port 2318. 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 2318, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2318'      # process listening on 2318
sudo lsof -nP -i :2318

macOS

sudo lsof -nP -i :2318

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2318 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2318
netstat -ano | findstr :2318

From another machine

nmap -p 2318 -sV <host>
sudo nmap -sU -p 2318 <host>
nc -zv <host> 2318

Block it in the firewall

sudo ufw deny 2318/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2318" -Direction Inbound -LocalPort 2318 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2318 used for?

Port 2318 is assigned by IANA to cadencecontrol (Cadence Control).

Is port 2318 TCP or UDP?

Port 2318 is registered for TCP and UDP.

Is it safe to open port 2318?

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 2318 is open?

On Linux run "ss -ltnup 'sport = :2318'", on macOS "lsof -nP -i :2318", and on Windows "netstat -ano | findstr :2318" to see the local process. From another machine, "nmap -p 2318 <host>" shows whether it is reachable.
