01 Security

Is port 8082 dangerous?

We have no specific security note for port 8082. 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 8082, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8082'      # process listening on 8082
sudo lsof -nP -i :8082

macOS

sudo lsof -nP -i :8082

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8082 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8082
netstat -ano | findstr :8082

From another machine

nmap -p 8082 -sV <host>
sudo nmap -sU -p 8082 <host>
nc -zv <host> 8082

Block it in the firewall

sudo ufw deny 8082/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8082" -Direction Inbound -LocalPort 8082 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8082 used for?

Port 8082 is assigned by IANA to us-cli (Utilistor (Client)).

Is port 8082 TCP or UDP?

Port 8082 is registered for TCP and UDP.

Is it safe to open port 8082?

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 8082 is open?

On Linux run "ss -ltnup 'sport = :8082'", on macOS "lsof -nP -i :8082", and on Windows "netstat -ano | findstr :8082" to see the local process. From another machine, "nmap -p 8082 <host>" shows whether it is reachable.
