Is port 2080 dangerous?

We have no specific security note for port 2080. 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 2080, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2080'      # process listening on 2080
sudo lsof -nP -i :2080

macOS

sudo lsof -nP -i :2080

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2080 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2080
netstat -ano | findstr :2080

From another machine

nmap -p 2080 -sV <host>
sudo nmap -sU -p 2080 <host>
nc -zv <host> 2080

Block it in the firewall

sudo ufw deny 2080/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2080" -Direction Inbound -LocalPort 2080 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2080 used for?

Port 2080 is assigned by IANA to autodesk-nlm (Autodesk NLM (FLEXlm)).

Is port 2080 TCP or UDP?

Port 2080 is registered for TCP and UDP.

Is it safe to open port 2080?

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 2080 is open?

On Linux run "ss -ltnup 'sport = :2080'", on macOS "lsof -nP -i :2080", and on Windows "netstat -ano | findstr :2080" to see the local process. From another machine, "nmap -p 2080 <host>" shows whether it is reachable.
