on the basics of upgrading UltraVNC remotely

Hi guys

This is not a specific "I need help" post but more about understanding UltraVNC in general.

Say I do have two PCs, one viewer, one server, both run some version of UltraVNC, e.x. v.1.0.0 RC 14 and most important, I do not havce physical access to the server since it stands at a colocation provider's facility.

Now a new version comes out, e.x. v1.0.0 RC16 and I want to update due to the bugfixes and cool new features. How do I do that? I mean I must update to RC16 remotely with the help of RC14, since I can not just sit in front of the server.

Thanks,
T.T.H.

P.S.: all my PCs run Win2000 SP4 latest patches

Hi,

Maybe install Ssh on the remote server and
log in using that. (OpenSsh for Windows as
the server and Putty as a possible client).

Once the ssh server is installed, Putty setup
to create a tunnel, and connection details
entered, you should be all set.

I simply connect to the server using putty,
log in using the systems username and
password. Then I minimize the window.

To connect with UltraVNC, assuming the
tunnel has been properly configured, simply
connect to localhost:0 (unless you are running
UltraVNC server on your local machine too..
then you should forward to another port.)

This way, you could download newer versions
and install to a different directory. Then, stop
the vnc service (which will disconnect you).

Heres the cool part.. you are still connected
with SSH. Go back to your ssh window, and
change directories to your new install of vnc.
run winvnc. reconnect your viewer to localhost
and voila.

Keep in mind I may have missed some things.
Ssh is definately a nice safety net.. in more
ways than one. Get it up and running, and
then play with it to see what you can do.

also, try searching google for ultravnc and
openssh. There are a few great pages out
there that probably explain it better than I.

Good Luck!

I prefer to use OpenVPN. It is more complicated, but you have full access including using things like the ps utilities and netsvc to start and stop processes and execute commands on the remote system.

You could also use FastPush (http://www.darkage.co.uk/) with OpenVPN.

Simple way:
using File Transfer copy all new files to new folder and run a batch script:

path\winvnc -kill
ren UltraVNC UltraVNCold
ren UltraVNCnew UltraVNC
path\winvnc

other manner useful only when VNC is registered as service:

net start winvnc
ren ...
ren ...
net stop winvnc

Ups. That will be better:

net stop winvnc
ren ...
ren ...
net start winvnc

You can also use the upgrade version of RC17
http://prdownloads.sourceforge.net/ultr ... p?download

Copy the zip to the remote machine
Unzip in the ultravnc directory
run upgrade.exe

The real upgrade is done on reboot. The upgrader only shedule the files for replacement

upgrade.log keeps a log of what files are going to be upgraded on, boot.
Works for vnc + driver
