  • 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 36602, and is it reachable?

Linux

sudo ss -ltnup 'sport = :36602'      # process listening on 36602
sudo lsof -nP -i :36602

macOS

sudo lsof -nP -i :36602

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 36602 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 36602
netstat -ano | findstr :36602

From another machine

nmap -p 36602 -sV <host>
nc -zv <host> 36602

Block it in the firewall

sudo ufw deny 36602/tcp                                         # Linux (ufw)

Is port 36602 TCP or UDP?

Port 36602 is registered for TCP.

Is it safe to open port 36602?

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 36602 is open?

On Linux run "ss -ltnup 'sport = :36602'", on macOS "lsof -nP -i :36602", and on Windows "netstat -ano | findstr :36602" to see the local process. From another machine, "nmap -p 36602 <host>" shows whether it is reachable.
