Is port 2915 dangerous?

We have no specific security note for port 2915. 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 2915, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2915'      # process listening on 2915
sudo lsof -nP -i :2915

macOS

sudo lsof -nP -i :2915

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2915 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2915
netstat -ano | findstr :2915

From another machine

nmap -p 2915 -sV <host>
sudo nmap -sU -p 2915 <host>
nc -zv <host> 2915

Block it in the firewall

sudo ufw deny 2915/tcp                                         # Linux (ufw)

Is port 2915 TCP or UDP?

Port 2915 is registered for TCP and UDP.

Is it safe to open port 2915?

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 2915 is open?

On Linux run "ss -ltnup 'sport = :2915'", on macOS "lsof -nP -i :2915", and on Windows "netstat -ano | findstr :2915" to see the local process. From another machine, "nmap -p 2915 <host>" shows whether it is reachable.
