01 Security

Is port 3076 dangerous?

We have no specific security note for port 3076. 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 3076, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3076'      # process listening on 3076
sudo lsof -nP -i :3076

macOS

sudo lsof -nP -i :3076

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3076 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3076
netstat -ano | findstr :3076

From another machine

nmap -p 3076 -sV <host>
sudo nmap -sU -p 3076 <host>
nc -zv <host> 3076

Block it in the firewall

sudo ufw deny 3076/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3076" -Direction Inbound -LocalPort 3076 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3076 used for?

Port 3076 is assigned by IANA to orbix-config (Orbix 2000 Config).

Is port 3076 TCP or UDP?

Port 3076 is registered for TCP and UDP.

Is it safe to open port 3076?

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 3076 is open?

On Linux run "ss -ltnup 'sport = :3076'", on macOS "lsof -nP -i :3076", and on Windows "netstat -ano | findstr :3076" to see the local process. From another machine, "nmap -p 3076 <host>" shows whether it is reachable.
