Is port 3898 dangerous?

We have no specific security note for port 3898. 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 3898, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3898'      # process listening on 3898
sudo lsof -nP -i :3898

macOS

sudo lsof -nP -i :3898

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3898 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3898
netstat -ano | findstr :3898

From another machine

nmap -p 3898 -sV <host>
sudo nmap -sU -p 3898 <host>
nc -zv <host> 3898

Block it in the firewall

sudo ufw deny 3898/tcp                                         # Linux (ufw)

Is port 3898 TCP or UDP?

Port 3898 is registered for TCP and UDP.

Is it safe to open port 3898?

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 = :3898'", on macOS "lsof -nP -i :3898", and on Windows "netstat -ano | findstr :3898" to see the local process. From another machine, "nmap -p 3898 <host>" shows whether it is reachable.
