10.5: Disable Screen Sharing's 'no encryption' warning
Authored by: mzs on Feb 09, '09 09:29:18AM

I tunnel my vnc over ssh, and I only get the warning at the beginning. Just add this when you ssh into the Linux box:

-L5910:127.0.0.1:5900

Then open vnc://localhost:5910/ in Screen Sharing.app, in fact I have it do it automatically from my ssh command line with this:

-o PermitLocalCommand=yes -o LocalCommand='/usr/bin/open vnc://localhost:5910/'

Then once you connect Screen Sharing.app will pop-up and connect to the Linux box (with that warning).

It is a really bad idea to just allow TCP port 5900 be unencrypted for all to see. That warning is there for a reason.

I like the LocalCommand—cheers! Note you shouldn't need the path to 'open'.

I would guess the hint submitter, like myself and many others, are connecting to these VNC servers on a LAN, behind a router, and the machines aren't exposed to the Internet. If the rest of your network is secure, there's not much to worry about.
