01 Security

Is port 9286 dangerous?

We have no specific security note for port 9286. 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 9286, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9286'      # process listening on 9286
sudo lsof -nP -i :9286

macOS

sudo lsof -nP -i :9286

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9286 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9286
netstat -ano | findstr :9286

From another machine

nmap -p 9286 -sV <host>
sudo nmap -sU -p 9286 <host>
nc -zv <host> 9286

Block it in the firewall

sudo ufw deny 9286/udp                                         # Linux (ufw)

04 FAQ
What is port 9286 used for?

Port 9286 is assigned by IANA to n2receive (n2 monitoring receiver).

Is port 9286 TCP or UDP?

Port 9286 is registered for UDP.

Is it safe to open port 9286?

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 9286 is open?

On Linux run "ss -ltnup 'sport = :9286'", on macOS "lsof -nP -i :9286", and on Windows "netstat -ano | findstr :9286" to see the local process. From another machine, "nmap -p 9286 <host>" shows whether it is reachable.
