Ubuntu 14.04 & Windows VNC Program

Click For Summary
SUMMARY

Ubuntu 14.04 introduced a bug that prevents TightVNC from connecting due to its use of TLS security type 18, which TightVNC does not support. Users seeking alternatives can consider NoMachine, a freeware solution that supports the required security protocols. Additionally, Windows Remote Desktop Connection can be utilized alongside XRDP, an open-source server that facilitates connections to Ubuntu systems. For command-line access, SSH with MobiXTerm allows for desktop forwarding, although performance may vary based on network conditions.

PREREQUISITES
  • Understanding of VNC protocols and their limitations
  • Familiarity with Ubuntu 14.04 and its desktop environments
  • Knowledge of Remote Desktop Protocol (RDP) and XRDP
  • Basic SSH usage and X-forwarding concepts
NEXT STEPS
  • Research NoMachine features and installation procedures
  • Learn how to configure and use XRDP on Ubuntu 14.04
  • Explore SSH tunneling and X-forwarding with MobiXTerm
  • Investigate alternative VNC clients that support TLS security type 18
USEFUL FOR

System administrators, remote desktop users, and anyone troubleshooting VNC connectivity issues on Ubuntu 14.04 will benefit from this discussion.

Hi there

A while back I updated Ubuntu to version 14.04. Before this, I could connect to the machine through TightVNC from my Windows 8.1 laptop.

However after the upgrade things didn't run smoothly. It is now a known bug that usual VNC software can't connect to Ubuntu 14.04 because it uses security TLS type (18), which TightVNC doesn't support.

My question is: is there any freeware available (for Windows) that does the job like TightVNC, but supports TLS security type 18?

The bug I report is mentioned https://bugs.launchpad.net/ubuntu/ source/vino/ bug/1281250

Many thanks for any assistance
Stevie

Whew I was a bit worried when I saw the subject line as I too felt stuck with VNC, knowing it was "dirty" but have no viable alternatives. Congrats on seeking a solid alternative. I think you may find this to your liking - https://www.nomachine.com/

Please forgive the self-quote. I'm a beast with a text editor but a fumbler with "rich-text" and maybe forum conventions. I merely wished to edit my post to change a mistake in tense and could see no other way to accomplish this (no longer showed an "edit" button). What method is right and proper or is there a time limit on edits?

BOT - Hope most followed the link to NOMACHINE... it is quite good.
 
Yes, I know the exact solution you are looking for.

Windows has a built-in server and client called Remote Desktop Connection. It works similar to VNC and forwards the whole graphics system.

XRDP is an open source server for this protocol. I don't really use it, but I tested it out and installed it on my Ubuntu server and it works fine. My server doesn't have X or a desktop manager installed, so I cannot speak from experience how well it works connecting to a unity or KDE plasma desktop, but it is able to give me the basic X-server environment (a terminal and opening windows) on my Windows Devices.

The other option I know of off the top of my head is to SSH into the Linux box using something like MobiXTerm. You should be able to start and forward the entire desktop from the command line, though I am not sure how quick X-forwarding would be in that case, especially if you are not on a gigabit network but rather using something like Wifi.
