Is port 575 dangerous?

We have no specific security note for port 575. 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 575, and is it reachable?

Linux

sudo ss -ltnup 'sport = :575'      # process listening on 575
sudo lsof -nP -i :575

macOS

sudo lsof -nP -i :575

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 575 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 575
netstat -ano | findstr :575

From another machine

nmap -p 575 -sV <host>
sudo nmap -sU -p 575 <host>
nc -zv <host> 575

Block it in the firewall

sudo ufw deny 575/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 575" -Direction Inbound -LocalPort 575 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 575 used for?

Port 575 is assigned by IANA to vemmi (VEMMI).

Is port 575 TCP or UDP?

Port 575 is registered for TCP and UDP.

Is it safe to open port 575?

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 575 is open?

On Linux run "ss -ltnup 'sport = :575'", on macOS "lsof -nP -i :575", and on Windows "netstat -ano | findstr :575" to see the local process. From another machine, "nmap -p 575 <host>" shows whether it is reachable.
