01 Security

Is port 2036 dangerous?

We have no specific security note for port 2036. 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 2036, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2036'      # process listening on 2036
sudo lsof -nP -i :2036

macOS

sudo lsof -nP -i :2036

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2036 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2036
netstat -ano | findstr :2036

From another machine

nmap -p 2036 -sV <host>
sudo nmap -sU -p 2036 <host>
nc -zv <host> 2036

Block it in the firewall

sudo ufw deny 2036/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2036" -Direction Inbound -LocalPort 2036 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2036 used for?

Port 2036 is assigned by IANA to e-dpnet (Ethernet WS DP network).

Is port 2036 TCP or UDP?

Port 2036 is registered for TCP and UDP.

Is it safe to open port 2036?

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 2036 is open?

On Linux run "ss -ltnup 'sport = :2036'", on macOS "lsof -nP -i :2036", and on Windows "netstat -ano | findstr :2036" to see the local process. From another machine, "nmap -p 2036 <host>" shows whether it is reachable.
