01 Security

Is port 3075 dangerous?

We have no specific security note for port 3075. 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 3075, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3075'      # process listening on 3075
sudo lsof -nP -i :3075

macOS

sudo lsof -nP -i :3075

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3075 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3075
netstat -ano | findstr :3075

From another machine

nmap -p 3075 -sV <host>
sudo nmap -sU -p 3075 <host>
nc -zv <host> 3075

Block it in the firewall

sudo ufw deny 3075/tcp                                         # Linux (ufw)

04 FAQ
What is port 3075 used for?

Port 3075 is assigned by IANA to orbix-locator (Orbix 2000 Locator).

Is port 3075 TCP or UDP?

Port 3075 is registered for TCP and UDP.

Is it safe to open port 3075?

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 3075 is open?

On Linux run "ss -ltnup 'sport = :3075'", on macOS "lsof -nP -i :3075", and on Windows "netstat -ano | findstr :3075" to see the local process. From another machine, "nmap -p 3075 <host>" shows whether it is reachable.
