01 Security

Is port 2844 dangerous?

We have no specific security note for port 2844. 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 2844, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2844'      # process listening on 2844
sudo lsof -nP -i :2844

macOS

sudo lsof -nP -i :2844

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2844 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2844
netstat -ano | findstr :2844

From another machine

nmap -p 2844 -sV <host>
sudo nmap -sU -p 2844 <host>
nc -zv <host> 2844

Block it in the firewall

sudo ufw deny 2844/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2844" -Direction Inbound -LocalPort 2844 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2844 used for?

Port 2844 is assigned by IANA to bpcp-poll (BPCP POLL).

Is port 2844 TCP or UDP?

Port 2844 is registered for TCP and UDP.

Is it safe to open port 2844?

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 2844 is open?

On Linux run "ss -ltnup 'sport = :2844'", on macOS "lsof -nP -i :2844", and on Windows "netstat -ano | findstr :2844" to see the local process. From another machine, "nmap -p 2844 <host>" shows whether it is reachable.
