How xmlrpc-beep works

A browser sends an HTTP request to port 602 and the xmlrpc-beep server sends the page back.

01 Security

Is port 602 dangerous?

We have no specific security note for port 602. Its risk depends on the program actually listening on it. General advice for web services:

  • Serve it over HTTPS only and check the HTTP security headers.
  • Keep admin consoles and development servers off the Internet.
  • Patch the application server and remove default credentials and sample apps.

03 Check it

Which program uses port 602, and is it reachable?

Linux

sudo ss -ltnup 'sport = :602'      # process listening on 602
sudo lsof -nP -i :602

macOS

sudo lsof -nP -i :602

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 602 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 602
netstat -ano | findstr :602

From another machine

nmap -p 602 -sV <host>
sudo nmap -sU -p 602 <host>
nc -zv <host> 602

Block it in the firewall

sudo ufw deny 602/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 602" -Direction Inbound -LocalPort 602 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 602 used for?

Port 602 is assigned by IANA to xmlrpc-beep (XML-RPC over BEEP).

Is port 602 TCP or UDP?

Port 602 is registered for TCP and UDP.

Is it safe to open port 602?

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. Serve it over HTTPS only and check the HTTP security headers.

How do I check if port 602 is open?

On Linux run "ss -ltnup 'sport = :602'", on macOS "lsof -nP -i :602", and on Windows "netstat -ano | findstr :602" to see the local process. From another machine, "nmap -p 602 <host>" shows whether it is reachable.
