01 Security

Is port 6082 dangerous?

We have no specific security note for port 6082. 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 6082, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6082'      # process listening on 6082
sudo lsof -nP -i :6082

macOS

sudo lsof -nP -i :6082

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6082 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6082
netstat -ano | findstr :6082

From another machine

nmap -p 6082 -sV <host>
sudo nmap -sU -p 6082 <host>
nc -zv <host> 6082

Block it in the firewall

sudo ufw deny 6082/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6082" -Direction Inbound -LocalPort 6082 -Protocol UDP -Action Block  # Windows
04 FAQ
What is port 6082 used for?

Port 6082 is assigned by IANA to p25cai (APCO Project 25 Common Air Interface - UDP encapsulation).

Is port 6082 TCP or UDP?

Port 6082 is registered for UDP.

Is it safe to open port 6082?

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 6082 is open?

On Linux run "ss -ltnup 'sport = :6082'", on macOS "lsof -nP -i :6082", and on Windows "netstat -ano | findstr :6082" to see the local process. From another machine, "nmap -p 6082 <host>" shows whether it is reachable.
