01 Security

Is port 2892 dangerous?

We have no specific security note for port 2892. 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 2892, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2892'      # process listening on 2892
sudo lsof -nP -i :2892

macOS

sudo lsof -nP -i :2892

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2892 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2892
netstat -ano | findstr :2892

From another machine

nmap -p 2892 -sV <host>
sudo nmap -sU -p 2892 <host>
nc -zv <host> 2892

Block it in the firewall

sudo ufw deny 2892/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2892" -Direction Inbound -LocalPort 2892 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2892 used for?

Port 2892 is assigned by IANA to snifferdata (SNIFFERDATA).

Is port 2892 TCP or UDP?

Port 2892 is registered for TCP and UDP.

Is it safe to open port 2892?

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 2892 is open?

On Linux run "ss -ltnup 'sport = :2892'", on macOS "lsof -nP -i :2892", and on Windows "netstat -ano | findstr :2892" to see the local process. From another machine, "nmap -p 2892 <host>" shows whether it is reachable.
