Yes, but I was actually referring to when he stated that... From Client: nmap -v -n -P0 -p5900-5906 euripide Warning: The -P0 option is deprecated. Please use -Pn Starting Nmap 7.70 ( https://nmap.org ) at 2020-02-16 10:09 CET Initiating Connect Scan at 10:09 Scanning euripide.u-bourgogne.fr (193.52.235.60) [7 ports] So, my assumption was that he was testing from a host on the internet. If I probe his system "euripide " I get PORT STATE SERVICE 22/tcp open ssh 5900/tcp closed vnc 5901/tcp closed vnc-1 5902/tcp closed vnc-2 5903/tcp closed vnc-3 5904/tcp closed unknown 5905/tcp closed unknown 5906/tcp closed unknown But if I probe another Linux system directly connected to the Internet I get PORT STATE SERVICE 22/tcp open ssh 5900/tcp filtered vnc 5901/tcp filtered vnc-1 5902/tcp filtered vnc-2 5903/tcp filtered vnc-3 5904/tcp filtered unknown 5905/tcp filtered unknown 5906/tcp filtered unknown This lead me to the conclusion that the VNC ports weren't opened at the Internet access point. And that something needed doing to fix/circumvent it. Anyway, he seems to have it working now running vncviewer over an ssh tunnel. FWIW, nmap can't accurately detect the what euripide is and reports...
