01 Security

Is port 2815 dangerous?

We have no specific security note for port 2815. 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 2815, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2815'      # process listening on 2815
sudo lsof -nP -i :2815

macOS

sudo lsof -nP -i :2815

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2815 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2815
netstat -ano | findstr :2815

From another machine

nmap -p 2815 -sV <host>
sudo nmap -sU -p 2815 <host>
nc -zv <host> 2815

Block it in the firewall

sudo ufw deny 2815/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2815" -Direction Inbound -LocalPort 2815 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2815 used for?

Port 2815 is assigned by IANA to lbc-measure (LBC Measurement).

Is port 2815 TCP or UDP?

Port 2815 is registered for TCP and UDP.

Is it safe to open port 2815?

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 2815 is open?

On Linux run "ss -ltnup 'sport = :2815'", on macOS "lsof -nP -i :2815", and on Windows "netstat -ano | findstr :2815" to see the local process. From another machine, "nmap -p 2815 <host>" shows whether it is reachable.
