We have no specific security note for port 2298. 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 2298, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2298'      # process listening on 2298
sudo lsof -nP -i :2298

macOS

sudo lsof -nP -i :2298

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2298 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2298
netstat -ano | findstr :2298

From another machine

nmap -p 2298 -sV <host>
sudo nmap -sU -p 2298 <host>
nc -zv <host> 2298

Block it in the firewall

sudo ufw deny 2298/tcp                                         # Linux (ufw)

Is port 2298 TCP or UDP?

Port 2298 is registered for TCP and UDP.

Is it safe to open port 2298?

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.

On Linux run "ss -ltnup 'sport = :2298'", on macOS "lsof -nP -i :2298", and on Windows "netstat -ano | findstr :2298" to see the local process. From another machine, "nmap -p 2298 <host>" shows whether it is reachable.
