My older friends who are moving far away soon have become Ubuntu Mate users and with very few exceptions it is going quite well for them. Once in a great while I know they will want some help - and hopping on a plane to go 1/2 way across the country to help them out for an hour or so simply ain't on the menu for me. In the past I have connected remotely with Linux boxes via keeping a dynamic DNS client updated for the server, using OpenVPN & VNC. Setting that up can be a real PITA though...and so I used Teamviewer for a while, until it demanded to be updated then refused to do the update on my old PC. One in-between solution seems to be X11VNC server, which is easy enough to set up for LAN usage - but I have yet to make it work over the internet - and its dev does not answer emails, sadly. Checked via general searches & at Alternativeto,net & all I found was either expensively limited payware or goofy freewares that don't do very much. The only solution I remain uncertain of right now is Vino, which may require some extra steps - but none of the pages I've read about it seem specific to using it via internet. If anyone here does this sort of remote connection to help others, please share pointers & info that might help me to get this solidly set up & working reliably ?? Thanks for any helpful replies !!
