01 Security

Is port 2810 dangerous?

We have no specific security note for port 2810. 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 2810, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2810'      # process listening on 2810
sudo lsof -nP -i :2810

macOS

sudo lsof -nP -i :2810

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2810 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2810
netstat -ano | findstr :2810

From another machine

nmap -p 2810 -sV <host>
sudo nmap -sU -p 2810 <host>
nc -zv <host> 2810

Block it in the firewall

sudo ufw deny 2810/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2810" -Direction Inbound -LocalPort 2810 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2810 used for?

Port 2810 is assigned by IANA to netsteward (Active Net Steward).

Is port 2810 TCP or UDP?

Port 2810 is registered for TCP and UDP.

Is it safe to open port 2810?

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 2810 is open?

On Linux run "ss -ltnup 'sport = :2810'", on macOS "lsof -nP -i :2810", and on Windows "netstat -ano | findstr :2810" to see the local process. From another machine, "nmap -p 2810 <host>" shows whether it is reachable.
