Is port 7786 dangerous?

We have no specific security note for port 7786. 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 7786, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7786'      # process listening on 7786
sudo lsof -nP -i :7786

macOS

sudo lsof -nP -i :7786

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7786 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7786
netstat -ano | findstr :7786

From another machine

nmap -p 7786 -sV <host>
sudo nmap -sU -p 7786 <host>
nc -zv <host> 7786

Block it in the firewall

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 7786 is open?

On Linux run "ss -ltnup 'sport = :7786'", on macOS "lsof -nP -i :7786", and on Windows "netstat -ano | findstr :7786" to see the local process. From another machine, "nmap -p 7786 <host>" shows whether it is reachable.
