Hi Dan,No, the service does not respond to any existing probes. It only responds when a proper client version handshake packet is sent, hence this script.
As an example, below is the output from 'nmap --version-all -sV -p4000 1.2.3.4':
Host is up (0.00046s latency). PORT STATE SERVICE VERSION 4000/tcp open unknown Thanks, -J On 01/19/2017 11:35 AM, Daniel Miller wrote:
Justin,Thanks so much for this script! It looks like this could be converted pretty easily to a version scan probe and match line. Does the service not respond to any existing probes? What is the output of nmap --version-all -sV -p4000 1.2.3.4? If we can reuse an existing probe and just add match lines, that would be great. Otherwise I will go ahead and add the probe to the nmap-service-probes file.DanOn Thu, Jan 19, 2017 at 10:00 AM, nmap user <nmapuser1 () gmail com <mailto:nmapuser1 () gmail com>> wrote:Hello, NoMachine is a popular cross-platform remote desktop solution. Attached is a NSE implementation to fingerprint/enumerate version details from a NoMachine Network Server. By sending a crafted packet declaring the client version, the server will respond with the version of nxd.
