Evening, gang.
I'm making this a "sticky" for Networking, so it can be easily found.
As some of you may recall, back in the days when the Linux TeamViewer package was WINE-based, I took over building them for a bit after cimarron dropped off the radar. This lasted up until TV13.
From TV14, TeamViewer gmBH moved to a native Qt5-based app, and deprecated every older version up until that point. Result? No more TeamViewer for Puppy, because neither wizard nor myself have had any luck with making it behave itself.
(I vaguely recall Phil B. managed to create a functional package for one of his Puppies, but he didn't follow this up, and no-one has had any joy since with duplicating that success.)
So; what to do?
--------------------------------------------------
Wizard and I have explored different avenues, and a few others have tried out various other applications. Some have attempted Google's Remote desktop app for Chrome, but apparently haven't got on very well with it. Remmina has been investigated; I found it was quite easy to create a portable of this, but it's a bit fiddly to use.
Wizard has had success with Anydesk. He and I have been maintaining a portable package between us, on & off, for quite a while now - but I've not been able to try it until very recently, because I never had a pair of sufficiently capable machines to experiment with. As of tonight, I can confirm that, yes; it works very well indeed......and despite the apparently complex mass of settings, very few of these actually need touching.
---------------------------------------------------
I took a look at NoMachine a few days back. To be blunt, it was a frickin' nightmare. Awkward, cumbersome, not at ALL 'intuitive'.....obviously designed for ubergeeks, neck-beards and IT departments, 'cos nobody in their right minds would have the patience to fart about with it to the extent that it seems to want. Top & bottom, it's really a tool built for the enterprise sector. I washed my hands of it, ASAP. Not for the likes of us. Eurrghhh..... 
I've had a lot more success with a web-based app called DWService. I came across this a few years ago, thought it sounded like a good idea - you run it though your browser! - and 'bookmarked' it. Again, I needed a better upgrade from the anciente P4-powered Dell lappie before I could attempt to use it. Trying to run a Chromium 'clone' with a P4 is worse than watching paint dry.....it's soooo slow.
All you do with this one is to visit their website & download a Python-based script. All Pups basically include Python these days, so that's no big deal, really. You execute this script on whatever Puppy you want to control via remote; it generates a unique, one-time user ID & password. You jot these down, visit the website again, enter the log-in details exactly as you wrote them down,and 'Sign-in'.
The magic all happens on DWService's servers. As with AnyDesk, it functions very smoothly & fluff-free. The only thing you don't get with this one - which you DO with AnyDesk - is a built-in chat client. Which is easy enough to work around.
(I'm a big believer in making use of on-line services wherever possible. There's on-line methods for doing almost anything you can imagine these days.....so why not employ them if you can?)
-------------------------------------------------
So. To recap:-
NoMachine - definitely not, unless you relish a challenge and enjoy making life hard for yourself.
AnyDesk - a good TV replacement. Works smoothly, and relatively lag-free - viewtopic.php?t=1104
Remmina - certainly usable, though CAN be fiddly. May require some understanding of VPNs, "tunnels" and such-like - viewtopic.php?t=6095
DWService - again, an easy-to-use TV replacement, this time web-based, making use of a 'portable' script - viewtopic.php?t=8490
-----------------------------------------------
Hopefully, this will help some of you to examine your options.
Mike.
