01 Security

Is port 2868 dangerous?

We have no specific security note for port 2868. 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 2868, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2868'      # process listening on 2868
sudo lsof -nP -i :2868

macOS

sudo lsof -nP -i :2868

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2868 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2868
netstat -ano | findstr :2868

From another machine

nmap -p 2868 -sV <host>
sudo nmap -sU -p 2868 <host>
nc -zv <host> 2868

Block it in the firewall

sudo ufw deny 2868/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2868" -Direction Inbound -LocalPort 2868 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2868 used for?

Port 2868 is assigned by IANA to npep-messaging (Norman Proprietaqry Events Protocol).

Is port 2868 TCP or UDP?

Port 2868 is registered for TCP and UDP.

Is it safe to open port 2868?

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 2868 is open?

On Linux run "ss -ltnup 'sport = :2868'", on macOS "lsof -nP -i :2868", and on Windows "netstat -ano | findstr :2868" to see the local process. From another machine, "nmap -p 2868 <host>" shows whether it is reachable.
