01 Security

Is port 7016 dangerous?

We have no specific security note for port 7016. 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 7016, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7016'      # process listening on 7016
sudo lsof -nP -i :7016

macOS

sudo lsof -nP -i :7016

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7016 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7016
netstat -ano | findstr :7016

From another machine

nmap -p 7016 -sV <host>
sudo nmap -sU -p 7016 <host>
nc -zv <host> 7016

Block it in the firewall

sudo ufw deny 7016/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7016" -Direction Inbound -LocalPort 7016 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7016 used for?

Port 7016 is assigned by IANA to spg (SPG Controls Carrier).

Is port 7016 TCP or UDP?

Port 7016 is registered for TCP and UDP.

Is it safe to open port 7016?

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 7016 is open?

On Linux run "ss -ltnup 'sport = :7016'", on macOS "lsof -nP -i :7016", and on Windows "netstat -ano | findstr :7016" to see the local process. From another machine, "nmap -p 7016 <host>" shows whether it is reachable.
