Is port 4182 dangerous?

We have no specific security note for port 4182. 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 4182, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4182'      # process listening on 4182
sudo lsof -nP -i :4182

macOS

sudo lsof -nP -i :4182

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4182 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4182
netstat -ano | findstr :4182

From another machine

nmap -p 4182 -sV <host>
sudo nmap -sU -p 4182 <host>
nc -zv <host> 4182

Block it in the firewall

sudo ufw deny 4182/tcp                                         # Linux (ufw)

Is port 4182 TCP or UDP?

Port 4182 is registered for TCP and UDP.

On Linux run "ss -ltnup 'sport = :4182'", on macOS "lsof -nP -i :4182", and on Windows "netstat -ano | findstr :4182" to see the local process. From another machine, "nmap -p 4182 <host>" shows whether it is reachable.
