SSVNC also works as a regular VNC viewer without encryption as well. In fact, the SSVNC web site states that SSVNC works with nearly any VNC Server host running SSHD and those running an SSL tunnel, including VeNCrypt SSL/TLS and Vino/ANONTLS encryption extensions to VNC on Unix, Mac OS X, and Windows. It’s also compatible with a wide range of VNC servers. However, using SSH to encrypt VNC communications can be a manually intensive and multi-step process requiring starting up SSH and VNC servers and configuring SSH and VNC clients for local or remote port forwarding.Īn Enhanced TightVNC Viewer, SSVNC, is a free multi-platform SSH/SSL VNC viewer that automates this process. For both aforementioned situations, SSH tunneling can be used to secure sessions between VNC servers and the most basic VNC client/viewers, regardless of any built-in protocols. In addition, many VNC client/viewers tend to be basic, so they generally don’t include any built-in encryption support. Although a number of VNC (Virtual Network Computing) servers include some type of built-in encryption, most do not. I don't recall if I ever was able to enable a logging session (If I did I don't recall how I enabled logging the connection attempt).VNC is one of many protocols used to share desktops between Linux and Windows PCs (see this Wikipedia entry for a comparison of various remote desktop software packages). If Remote Login is enabled, then you may first need to establish an SSH tunnel before being able to connect using VNC. When using the command line I am prompted for the Mac's VNC password before it launches a window for the remote GUI session. I have also enabled 'Observe' & 'Control' found on the 'Options' button for the authorized user. On the Mac I have enabled a VNC password (click on 'Computer Settings' button under Remote Management). On Linux I use the following command to connect to a Mac using VNC (xtightvncviewer is being used - I believe you can just use the tightvncviewer command as well): vncviewer Plus different versions of macOS seem to behave differently.

I don't have these issues when connecting to a Linux remote system. Even when I connected to the remote Mac the graphics in the session were very slow to load and both computers are on the same LAN. When I was having trouble I was able to enter my VNC password, but a VNC window never opened. After disconnecting from the VNC session I was unable to access the remote Mac via VNC for a while. I had to try multiple times before I was able to connect. I actually was having trouble connecting to a Mac using VNC myself.
