01 Security

Is port 4082 dangerous?

We have no specific security note for port 4082. 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 4082, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4082'      # process listening on 4082
sudo lsof -nP -i :4082

macOS

sudo lsof -nP -i :4082

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4082 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4082
netstat -ano | findstr :4082

From another machine

nmap -p 4082 -sV <host>
sudo nmap -sU -p 4082 <host>
nc -zv <host> 4082

Block it in the firewall

sudo ufw deny 4082/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4082" -Direction Inbound -LocalPort 4082 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4082 used for?

Port 4082 is assigned by IANA to lorica-out (Lorica outside facing).

Is port 4082 TCP or UDP?

Port 4082 is registered for TCP and UDP.

Is it safe to open port 4082?

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 4082 is open?

On Linux run "ss -ltnup 'sport = :4082'", on macOS "lsof -nP -i :4082", and on Windows "netstat -ano | findstr :4082" to see the local process. From another machine, "nmap -p 4082 <host>" shows whether it is reachable.
