01 Security

Is port 5082 dangerous?

We have no specific security note for port 5082. 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 5082, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5082'      # process listening on 5082
sudo lsof -nP -i :5082

macOS

sudo lsof -nP -i :5082

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5082 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5082
netstat -ano | findstr :5082

From another machine

nmap -p 5082 -sV <host>
sudo nmap -sU -p 5082 <host>
nc -zv <host> 5082

Block it in the firewall

sudo ufw deny 5082/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5082" -Direction Inbound -LocalPort 5082 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5082 used for?

Port 5082 is assigned by IANA to qcp (Qpur Communication Protocol).

Is port 5082 TCP or UDP?

Port 5082 is registered for TCP and UDP.

Is it safe to open port 5082?

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 5082 is open?

On Linux run "ss -ltnup 'sport = :5082'", on macOS "lsof -nP -i :5082", and on Windows "netstat -ano | findstr :5082" to see the local process. From another machine, "nmap -p 5082 <host>" shows whether it is reachable.
