01 Security

Is port 2870 dangerous?

We have no specific security note for port 2870. 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 2870, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2870'      # process listening on 2870
sudo lsof -nP -i :2870

macOS

sudo lsof -nP -i :2870

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2870 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2870
netstat -ano | findstr :2870

From another machine

nmap -p 2870 -sV <host>
sudo nmap -sU -p 2870 <host>
nc -zv <host> 2870

Block it in the firewall

sudo ufw deny 2870/tcp                                         # Linux (ufw)

What is port 2870 used for?

Port 2870 is assigned by IANA to daishi (daishi).

Is port 2870 TCP or UDP?

Port 2870 is registered for TCP and UDP.

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 2870 is open?

On Linux run "ss -ltnup 'sport = :2870'", on macOS "lsof -nP -i :2870", and on Windows "netstat -ano | findstr :2870" to see the local process. From another machine, "nmap -p 2870 <host>" shows whether it is reachable.
