Is port 7235 dangerous?

We have no specific security note for port 7235. 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 7235, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7235'      # process listening on 7235
sudo lsof -nP -i :7235

macOS

sudo lsof -nP -i :7235

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7235 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7235
netstat -ano | findstr :7235

From another machine

nmap -p 7235 -sV <host>
sudo nmap -sU -p 7235 <host>
nc -zv <host> 7235

Block it in the firewall

sudo ufw deny 7235/udp                                         # Linux (ufw)

Is port 7235 TCP or UDP?

Port 7235 is registered for UDP.

Is it safe to open port 7235?

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 7235 is open?

On Linux run "ss -ltnup 'sport = :7235'", on macOS "lsof -nP -i :7235", and on Windows "netstat -ano | findstr :7235" to see the local process. From another machine, "nmap -p 7235 <host>" shows whether it is reachable.
