Is port 8115 dangerous?

We have no specific security note for port 8115. 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 8115, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8115'      # process listening on 8115
sudo lsof -nP -i :8115

macOS

sudo lsof -nP -i :8115

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8115 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8115
netstat -ano | findstr :8115

From another machine

nmap -p 8115 -sV <host>
sudo nmap -sU -p 8115 <host>
nc -zv <host> 8115

Block it in the firewall

sudo ufw deny 8115/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 8115 is open?

On Linux run "ss -ltnup 'sport = :8115'", on macOS "lsof -nP -i :8115", and on Windows "netstat -ano | findstr :8115" to see the local process. From another machine, "nmap -p 8115 <host>" shows whether it is reachable.
