01 Security

Is port 4350 dangerous?

We have no specific security note for port 4350. 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 4350, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4350'      # process listening on 4350
sudo lsof -nP -i :4350

macOS

sudo lsof -nP -i :4350

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4350 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4350
netstat -ano | findstr :4350

From another machine

nmap -p 4350 -sV <host>
sudo nmap -sU -p 4350 <host>
nc -zv <host> 4350

Block it in the firewall

sudo ufw deny 4350/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4350" -Direction Inbound -LocalPort 4350 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4350 used for?

Port 4350 is assigned by IANA to net-device (Net Device).

Is port 4350 TCP or UDP?

Port 4350 is registered for TCP and UDP.

Is it safe to open port 4350?

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 4350 is open?

On Linux run "ss -ltnup 'sport = :4350'", on macOS "lsof -nP -i :4350", and on Windows "netstat -ano | findstr :4350" to see the local process. From another machine, "nmap -p 4350 <host>" shows whether it is reachable.
