Is port 2769 dangerous?

We have no specific security note for port 2769. 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 2769, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2769'      # process listening on 2769
sudo lsof -nP -i :2769

macOS

sudo lsof -nP -i :2769

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2769 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2769
netstat -ano | findstr :2769

From another machine

nmap -p 2769 -sV <host>
sudo nmap -sU -p 2769 <host>
nc -zv <host> 2769

Block it in the firewall

sudo ufw deny 2769/tcp                                         # Linux (ufw)

What is port 2769 used for?

Port 2769 is assigned by IANA to exce (eXcE).

Is port 2769 TCP or UDP?

Port 2769 is registered for TCP and UDP.

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 2769 is open?

On Linux run "ss -ltnup 'sport = :2769'", on macOS "lsof -nP -i :2769", and on Windows "netstat -ano | findstr :2769" to see the local process. From another machine, "nmap -p 2769 <host>" shows whether it is reachable.
