Security and web controlled VIs

[urs boegli]

I've just installed LV6.1 and I'm happy with these new features to
control your VIs with any browser on the web.
We would like to give some employees the possibility to watch a running
process from back home so they can adapt parameters, stop it or at least
deciding wther they should come in.
There are a few problems, slightly OT:

We have a firewall where we could open the netweork for fixed TCPIP
adresses, but people do have variable ones
Same problem with the LV6.1 Webserver, open to everyone or specific
adresses.

One solution might be to add an additional modem and have a kind of
point to point tcp-ip connection...

Any better ideas?

Thanks Urs

Urs,

I would suggest a password protection system. This can be done with a number of freely available web servers or with the G Web Server that comes with the Internet Toolset. If you already have a web server set up for your company, you could create a page that requires someone to log in. Once that is done, that web server can redirect them to (or get a page from) the LabVIEW Web Server for viewing the remote panels. This is probably the easiest solution and does not have to deal with IP addresses.

Randy,

I want to do exactly what you suggest.
How can I "redirect to" or "get the page from" the LabVIEW Webserver.
My first webserver is the Xitami.

I think this would be possible:
1. Xitami Webserber is listening on port 80
2. LabVIEW Webserver is listening lets say on port 90
3. If he password is ok, I could present a link to machine:90/pagex

But is that safe ?

And what do you mean with first Server "get a page from" second Server.

Would be great, if you could give me some more advice.

Hi Thomas,

You would do these things on the external webserver itself, it would be best to seek support from them. If you have the address of the G server, then you just need to put that in the right spots on the external server, it isn't NI=specific at this point.
