- 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.

Which program uses port 7775, and is it reachable?
Linux
sudo ss -ltnup 'sport = :7775' # process listening on 7775
sudo lsof -nP -i :7775macOS
sudo lsof -nP -i :7775
Windows (PowerShell)

From another machine
nmap -p 7775 -sV <host> nc -zv <host> 7775

Is it safe to open port 7775?
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 7775 is open?
On Linux run "ss -ltnup 'sport = :7775'", on macOS "lsof -nP -i :7775", and on Windows "netstat -ano | findstr :7775" to see the local process. From another machine, "nmap -p 7775 <host>" shows whether it is reachable.
