01 Security

Is port 4157 dangerous?

We have no specific security note for port 4157. 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 4157, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4157'      # process listening on 4157
sudo lsof -nP -i :4157

macOS

sudo lsof -nP -i :4157

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4157 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4157
netstat -ano | findstr :4157

From another machine

nmap -p 4157 -sV <host>
sudo nmap -sU -p 4157 <host>
nc -zv <host> 4157

Block it in the firewall

sudo ufw deny 4157/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4157" -Direction Inbound -LocalPort 4157 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4157 used for?

Port 4157 is assigned by IANA to stat-scanner (STAT Scanner Control).

Is port 4157 TCP or UDP?

Port 4157 is registered for TCP and UDP.

Is it safe to open port 4157?

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 4157 is open?

On Linux run "ss -ltnup 'sport = :4157'", on macOS "lsof -nP -i :4157", and on Windows "netstat -ano | findstr :4157" to see the local process. From another machine, "nmap -p 4157 <host>" shows whether it is reachable.
