01 Security

Is port 2476 dangerous?

We have no specific security note for port 2476. 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 2476, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2476'      # process listening on 2476
sudo lsof -nP -i :2476

macOS

sudo lsof -nP -i :2476

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2476 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2476
netstat -ano | findstr :2476

From another machine

nmap -p 2476 -sV <host>
sudo nmap -sU -p 2476 <host>
nc -zv <host> 2476

Block it in the firewall

sudo ufw deny 2476/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2476" -Direction Inbound -LocalPort 2476 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2476 used for?

Port 2476 is assigned by IANA to ace-svr-prop (ACE Server Propagation).

Is port 2476 TCP or UDP?

Port 2476 is registered for TCP and UDP.

Is it safe to open port 2476?

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 2476 is open?

On Linux run "ss -ltnup 'sport = :2476'", on macOS "lsof -nP -i :2476", and on Windows "netstat -ano | findstr :2476" to see the local process. From another machine, "nmap -p 2476 <host>" shows whether it is reachable.
