01 Security

Is port 3080 dangerous?

We have no specific security note for port 3080. 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 3080, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3080'      # process listening on 3080
sudo lsof -nP -i :3080

macOS

sudo lsof -nP -i :3080

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3080 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3080
netstat -ano | findstr :3080

From another machine

nmap -p 3080 -sV <host>
sudo nmap -sU -p 3080 <host>
nc -zv <host> 3080

Block it in the firewall

sudo ufw deny 3080/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3080" -Direction Inbound -LocalPort 3080 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3080 used for?

Port 3080 is assigned by IANA to stm_pproc (stm_pproc), stm-pproc (stm_pproc IANA assigned this well-formed service name as a replacement for "stm_pproc".).

Is port 3080 TCP or UDP?

Port 3080 is registered for TCP and UDP.

Is it safe to open port 3080?

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 3080 is open?

On Linux run "ss -ltnup 'sport = :3080'", on macOS "lsof -nP -i :3080", and on Windows "netstat -ano | findstr :3080" to see the local process. From another machine, "nmap -p 3080 <host>" shows whether it is reachable.
