How to make UVNC server automatically reverse call Repeater

Post by swinster »

Hi,

I want to be able to remote manage LOTS of computers with any interaction at the server end, but also use the repeater in Mode 2 due to firewall restrictions, also using encryption.

I have successfully set up the repeater so that a viewer and server can connect via the repeater using encryption. Of course, to do this the server has to initiate a reverse connection to the repeater but I can only seem to do this manually using "Add client". In addition, when the viewer disconnects, the server connection is also lost, which means it needs to be re-initiated.

Is there any way to get the server to automatically initiate the reverse connection when the computer boots and to keep this connection active after the viewer disconnects? I'm not sure if there is any network bandwidth used when a server connects to the repeater and what the implication might be if a lot (read 100) of computer were connected.

Is any of this possible?

Many thanks
Chris

AH, maybe this is available in UVNC 1.04. It's difficult to figure out but there seems to be some discussion of auto reconnect to the repeater AND getting this to work as a service. Can anyone confirm?

Just in case anyone else needs to do this here is the answer.

From UVNC version 1.04, a comand line call has been added that can start the server iwith a reverse connection to a repeater AND get it to reconnect should the connection be severed. This commend is:

-autoreconnect ID:12345678 -connect hostIPaddress

In addition, the UVNC server now utilises a "ultravnc.ini" file located in the same directory as the server - usually "c:\Program files\UltraVNC". The command line operation can also be added to this file so that if the UVNC server is run as a service, it can also take advantage of these commands

In this file are stored the setting used by the UltraVNC server. The There is a section labelled as :

[Admin]

In this section add the following line:-

service_commandline=-autoreconnect ID:12345678 -connect hostIPaddress


Now you UltraVNC server can automatically connect to a repeater and you can remotely manage many computers behind different firewalls without the need for user interaction at the server.

However, there seems to be a serious security risk with the repeater. Not sure what can be done about that.
