01 Security

Is port 3036 dangerous?

We have no specific security note for port 3036. 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 3036, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3036'      # process listening on 3036
sudo lsof -nP -i :3036

macOS

sudo lsof -nP -i :3036

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3036 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3036
netstat -ano | findstr :3036

From another machine

nmap -p 3036 -sV <host>
sudo nmap -sU -p 3036 <host>
nc -zv <host> 3036

Block it in the firewall

sudo ufw deny 3036/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3036" -Direction Inbound -LocalPort 3036 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3036 used for?

Port 3036 is assigned by IANA to hagel-dump (Hagel DUMP).

Is port 3036 TCP or UDP?

Port 3036 is registered for TCP and UDP.

Is it safe to open port 3036?

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 3036 is open?

On Linux run "ss -ltnup 'sport = :3036'", on macOS "lsof -nP -i :3036", and on Windows "netstat -ano | findstr :3036" to see the local process. From another machine, "nmap -p 3036 <host>" shows whether it is reachable.
