01 Security

Is port 1057 dangerous?

We have no specific security note for port 1057. 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 1057, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1057'      # process listening on 1057
sudo lsof -nP -i :1057

macOS

sudo lsof -nP -i :1057

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1057 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1057
netstat -ano | findstr :1057

From another machine

nmap -p 1057 -sV <host>
sudo nmap -sU -p 1057 <host>
nc -zv <host> 1057

Block it in the firewall

sudo ufw deny 1057/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1057" -Direction Inbound -LocalPort 1057 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1057 used for?

Port 1057 is assigned by IANA to startron (STARTRON).

Is port 1057 TCP or UDP?

Port 1057 is registered for TCP and UDP.

Is it safe to open port 1057?

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 1057 is open?

On Linux run "ss -ltnup 'sport = :1057'", on macOS "lsof -nP -i :1057", and on Windows "netstat -ano | findstr :1057" to see the local process. From another machine, "nmap -p 1057 <host>" shows whether it is reachable.
