01 Security

Is port 36411 dangerous?

We have no specific security note for port 36411. 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 36411, and is it reachable?

Linux

sudo ss -ltnup 'sport = :36411'      # process listening on 36411
sudo lsof -nP -i :36411

macOS

sudo lsof -nP -i :36411

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 36411 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 36411
netstat -ano | findstr :36411

From another machine

nmap -p 36411 -sV <host>
sudo nmap -sU -p 36411 <host>
nc -zv <host> 36411

Block it in the firewall

sudo ufw deny 36411/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 36411" -Direction Inbound -LocalPort 36411 -Protocol UDP -Action Block  # Windows
04 FAQ
What is port 36411 used for?

Port 36411 is assigned by IANA to wlcp (Wireless LAN Control plane Protocol (WLCP)).

Is port 36411 TCP or UDP?

Port 36411 is registered for UDP.

Is it safe to open port 36411?

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 36411 is open?

On Linux run "ss -ltnup 'sport = :36411'", on macOS "lsof -nP -i :36411", and on Windows "netstat -ano | findstr :36411" to see the local process. From another machine, "nmap -p 36411 <host>" shows whether it is reachable.
