01 Security

Is port 2076 dangerous?

We have no specific security note for port 2076. 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 2076, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2076'      # process listening on 2076
sudo lsof -nP -i :2076

macOS

sudo lsof -nP -i :2076

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2076 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2076
netstat -ano | findstr :2076

From another machine

nmap -p 2076 -sV <host>
sudo nmap -sU -p 2076 <host>
nc -zv <host> 2076

Block it in the firewall

sudo ufw deny 2076/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2076" -Direction Inbound -LocalPort 2076 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2076 used for?

Port 2076 is assigned by IANA to newlixconfig (Newlix JSPConfig).

Is port 2076 TCP or UDP?

Port 2076 is registered for TCP and UDP.

Is it safe to open port 2076?

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 2076 is open?

On Linux run "ss -ltnup 'sport = :2076'", on macOS "lsof -nP -i :2076", and on Windows "netstat -ano | findstr :2076" to see the local process. From another machine, "nmap -p 2076 <host>" shows whether it is reachable.
