01 Security

Is port 9080 dangerous?

We have no specific security note for port 9080. 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 9080, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9080'      # process listening on 9080
sudo lsof -nP -i :9080

macOS

sudo lsof -nP -i :9080

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9080 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9080
netstat -ano | findstr :9080

From another machine

nmap -p 9080 -sV <host>
sudo nmap -sU -p 9080 <host>
nc -zv <host> 9080

Block it in the firewall

sudo ufw deny 9080/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9080" -Direction Inbound -LocalPort 9080 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 9080 used for?

Port 9080 is assigned by IANA to glrpc (Groove GLRPC).

Is port 9080 TCP or UDP?

Port 9080 is registered for TCP and UDP.

Is it safe to open port 9080?

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 9080 is open?

On Linux run "ss -ltnup 'sport = :9080'", on macOS "lsof -nP -i :9080", and on Windows "netstat -ano | findstr :9080" to see the local process. From another machine, "nmap -p 9080 <host>" shows whether it is reachable.
