Is port 4162 dangerous?

We have no specific security note for port 4162. 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 4162, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4162'      # process listening on 4162
sudo lsof -nP -i :4162

macOS

sudo lsof -nP -i :4162

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4162 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4162
netstat -ano | findstr :4162

From another machine

nmap -p 4162 -sV <host>
sudo nmap -sU -p 4162 <host>
nc -zv <host> 4162

Block it in the firewall

sudo ufw deny 4162/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4162" -Direction Inbound -LocalPort 4162 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4162 used for?

Port 4162 is assigned by IANA to omstopology (OMS Topology).

Is port 4162 TCP or UDP?

Port 4162 is registered for TCP and UDP.

Is it safe to open port 4162?

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 4162 is open?

On Linux run "ss -ltnup 'sport = :4162'", on macOS "lsof -nP -i :4162", and on Windows "netstat -ano | findstr :4162" to see the local process. From another machine, "nmap -p 4162 <host>" shows whether it is reachable.
