Webex is incredibly expensive because of its proxy nature. I don't
think a lot of people realize that companies can easily spend
$50,000/year on webex. We use it for product demos and to support
customers with very restrictive firewalls, which is not all that often
and we probably spend $5,000/year.
A good replacement would be most welcome, mainly a version of VNC that
auto downloads and installs with little user interaction and connects
back to a specific ip/port. When the session is done, it should
Yes, VNC can initiate a connection from the server side, I use it all
the time to support my servers deployed in the field. Depending on your
needs, you might not have to create any new software. Webex's strength
is at taking a random computer on the Internet and quickly connecting it
to your computer. However, this is not what you are wanting to do. You
want to take very specific computers, your Kiosks and connect to them.
The servers I deploy in the field are behind firewalls as are the
computers at the support center. Each server ships with a "Support"
folder on the start menu. Under that folder is a list of numbered
shortcuts, each one assigned to a support machine at the home office.
When a user calls in with a problem, the support rep just tells the
user to use the support link assigned to his computer.
Each link maps to the IP of the home office and ports 5500 to 5510. The
firewall at the home office routes each port to port 5500 on the
internal support machines. While not 100% the best practice, having
port 5500 open on these machines has very little actual risk.
If you need a more complex connection system, then a proxy like webex
uses is probably the way to go. However, if your remote firewalls allow
outbound connections on port 5500 then try to go the simple route.
