Is port 4180 dangerous?

We have no specific security note for port 4180. 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 4180, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4180'      # process listening on 4180
sudo lsof -nP -i :4180

macOS

sudo lsof -nP -i :4180

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4180 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4180
netstat -ano | findstr :4180

From another machine

nmap -p 4180 -sV <host>
sudo nmap -sU -p 4180 <host>
nc -zv <host> 4180

Block it in the firewall

sudo ufw deny 4180/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4180" -Direction Inbound -LocalPort 4180 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4180 used for?

Port 4180 is assigned by IANA to httpx (HTTPX).

Is port 4180 TCP or UDP?

Port 4180 is registered for TCP and UDP.

Is it safe to open port 4180?

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 4180 is open?

On Linux run "ss -ltnup 'sport = :4180'", on macOS "lsof -nP -i :4180", and on Windows "netstat -ano | findstr :4180" to see the local process. From another machine, "nmap -p 4180 <host>" shows whether it is reachable.
