01 Security

Is port 6080 dangerous?

We have no specific security note for port 6080. 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 6080, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6080'      # process listening on 6080
sudo lsof -nP -i :6080

macOS

sudo lsof -nP -i :6080

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6080 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6080
netstat -ano | findstr :6080

From another machine

nmap -p 6080 -sV <host>
sudo nmap -sU -p 6080 <host>
nc -zv <host> 6080

Block it in the firewall

sudo ufw deny 6080/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6080" -Direction Inbound -LocalPort 6080 -Protocol UDP -Action Block  # Windows
04 FAQ
What is port 6080 used for?

Port 6080 is assigned by IANA to gue (Generic UDP Encapsulation).

Is port 6080 TCP or UDP?

Port 6080 is registered for UDP.

Is it safe to open port 6080?

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 6080 is open?

On Linux run "ss -ltnup 'sport = :6080'", on macOS "lsof -nP -i :6080", and on Windows "netstat -ano | findstr :6080" to see the local process. From another machine, "nmap -p 6080 <host>" shows whether it is reachable.
