We've had pretty good success using the X2Go program to enable remote
access to both our server and our clients but I have just found
Guacamole (http://guac-dev.org/) which looks interesting.
I like it because it doesn't require that a client be installed on the
remote user's machine.
But, on the other hand, I don't like that it uses VNC which I think is
slower than the X protocol that X2Go uses (but I could be wrong).
Having just started looking at Guacamole, it sounds like it can use
any remote server so it might be possible to get the best of both
worlds and have Guacamole access the x2go remote x server.
Guacamole sounded like a good topic for discussion too.
Sounds reallly interesting. I've just switched from using VNC to using
X2Go and the speed difference is huge. Using VNC was painfully slow
even with full compression on, however using X2Go over the XDMCP
protocol it's very fast, almost native speed over a 0.70mbit/sec upload
link.
I would be interested to see if Guacamole performs the same?

I've been using Vino (VNC server) on the LTSP server with
https://meshcentral.com/.
I'm using it because it's free for both business and personal use, it's
supported by Intel, client access is simple via a web browser, and it
also knows how to traverse the router's firewall without setting up
something like port forwarding.
But it is currently only Alpha software (though it seems stable and
decently reliable), and I also find it to be slow. It's also not in my
distro's (Ubuntu) repositories.
Can anyone say whether X2Go or Guacamole handle firewall traversal so
easily?
X2Go works over SSH so as long as you have a port open for ssh
(recommend something other than 22, eg: 2222) then you can use that
one port for everything, also you could install fail2ban to stop brute
force attacks on this port.

Trying to look into both X2Go and Guacamole, I found that Guacamole's
documentation is well-written and well-organized, and X2Go's is painful.
It seems that both Guacamole and X2Go move the gateway proxy function --
that is currently handled for me by meshcentral.com -- onto the remote
server. My remote server currently runs just vino on-demand, and with
either Guacamole or X2Go it would have to run other components as well
e.g. Tomcat and the Guacamole software. So unless those additional
components can also be set up to run on-demand, those solutions add some
overhead to the running load.
Guacamole's design as a web application means that it can traverse the
firewall with no firewall configuration required. It communicates with
a local remote desktop server as a backend behind the firewall. If VNC
is used, it is used only locally between Guacamole and the remote
desktop server. All very nice. With X2Go, it seems that firewall
configuration would be required.
I like Robert Lefebvre's initial idea: "it sounds like it can use any
remote server so it might be possible to get the best of both worlds and
have Guacamole access the x2go remote x server." I like it especially
if someone knows how to run Guacamole and X2Go on-demand, and if all
that, when running, did not bog down desktops with modest specs.

On a related line of thought: I have found VNC remote control on the LAN
to be beautifully fast, but it seems to be the consensus that VNC-based
remote control solutions over the Internet are slow (as well as
insecure). I was eventually going to try VNC over a VPN as an
alternative to Logmein for support of Windows business desktops (not
supposed to use free Logmein for that), but if that setup were as slow
as Vino + meshcentral.com, then it would not seem to be a very good
solution. Can anyone speak from experience or with some certainty about
that?
