I just downloaded this package VNC-Viewer-6.17.731-Linux-x64-ANY.tar to install the VNC viewer. I want to do the installation manually without using the yum. When I type the ./vncinstall command to perform the installation it gives me the following:
Copying vncviewer to /usr/bin
Copying vncviewer.1 to /usr/share/man/man1/vncviewer.1
Does this mean that the vnc was properly installed?
Yes, it does mean it was installed correctly. You can run it with vncviewer. vncviewer.1 is the man page (documentation) for the executable.
