03 Check it

Which program uses port 2917, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2917'      # process listening on 2917
sudo lsof -nP -i :2917

macOS

sudo lsof -nP -i :2917

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2917 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2917
netstat -ano | findstr :2917

From another machine

nmap -p 2917 -sV <host>
sudo nmap -sU -p 2917 <host>
nc -zv <host> 2917

Block it in the firewall

sudo ufw deny 2917/tcp                                         # Linux (ufw)

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 2917 is open?

On Linux run "ss -ltnup 'sport = :2917'", on macOS "lsof -nP -i :2917", and on Windows "netstat -ano | findstr :2917" to see the local process. From another machine, "nmap -p 2917 <host>" shows whether it is reachable.
