Marayong,

It'll work if no authentication is needed or if integrated authentication with Windows exists. I have no proxy to suggest but by sandbox you mean virtual machine ? If so I'm not sure it'll work unless the virtual machine provides 3D virtual graphics. (I tried running it using Remote Desktop and failed)

I think this happens when the proxy sends back a Not Authorized response and the browser opens a dialog requesting user and password. But I've also seen some companies that you need to access a proxy page to provide user and password before doing any other access.

Not sure which one but I think the users having this problem could provide more information.

rbn:

Edit WWTExplorer.exe.config
just before the closing tag include the text bellow (with the needed changes)

<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy proxyaddress="http://proxy_server_address:proxy_server_port" bypassonlocal="true"/>
</defaultProxy>
</system.net>
chage proxy_server_address to your proxy server

and

proxy_server_port to the port the proxy is working on

Done all of the above, but still doesn't work.

Our proxy server is a Navaho box, which runs on Linux, but authenticates against Active Directory. Normally it uses the default logon credtientials of the computer, dropping through to a logon dialog if the user is not recognised. I.E. works fine.

however WWT still says it cannot detect a network connection.

Robin

Have you tried changing bypassonlocal to false ?

zaphod:

I am at a school using a proxy server but it is accessed using a configuration script, there are no entrys in the proxy server or port boxes. I have tried editing the wwtexplorer.exe.config file with some proxy settings that the IT guys gave me but all I get is an error message telling me the program has to shut down. Would there be some alteration to the wwtexplorer.exe.config that would use the address for the script rather than the proxy address. The problem is that for new sites I usually get asked for my user name and password which doesn't happen when  wwt is launched.

Btw brilliant site which I am enjoying at home, just wish I could show them at school. Cheers.

Check IE connection page If you have the configuration script box checked you can get it's url, paste in the IE address line and see what is inside the script.
There you may find: HttpPort=xxx and new Node(yyy).(At least the old script we used to use here had those entries and they are the same addreess and port for the proxy server.
Not sure this will work as you said that you're asked for user and password and this change in config does not cover this.
Jacques

P.S.

<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy proxyaddress="http://proxy_server_address:proxy_server_port" bypassonlocal="true"/>
</defaultProxy>
</system.net>

possible changes:
1) <proxy proxyaddress="http://proxy_server_address:proxy_server_port" bypassonlocal="true" autoDetect="true"/>
or
2) <proxy proxyaddress="http://proxy_server_address:proxy_server_port" bypassonlocal="true" usesystemdefault="true"/>
or
3) <proxy proxyaddress="http://proxy_server_address:proxy_server_port" bypassonlocal="true" scruptLocation="some_url"/>

1) will work like IE when it's autodetecting the proxy
2) will useIE settings
3) will work like IE if a script is provided

I suggest trying 2) first :) but I doubt any will work if you need to rpovide user/pwd but as I can't test this behavior I may be wrong

Have you tried changing bypassonlocal to false ? Jacques

Yes I have tried bypassonlocal=false as well, but no difference. As Jacques suggested (although I think it should be true)

Our proxy server does an ntlm authentication if passed appropriate credentials, otherwise (on IE) falls through to a standard logon dialog box.

IE is connecting seamlessly to the internet for the logged on user to the PC box (logged on to our local MS AD domain) on which WWT is alos running. However, despite adding the suggested configuration for <system.net> to the config file there is no difference. I still get the message that no internet connection is found.

 Now tried the other options (usesystemdefault and autoDetect) suggested by Jacques but still no go. Script alternative not relevant in my case.

Please, try the other 3 (starting for option 2) changes in the big post I made today

I'm having the same problem, except I don't have a proxy server, just a wireless router connected to a cable modem.  Oddly, when I connect with a different laptop, it works just fine.  Both PCs have the proxy server setting turned off.  Turning it on doesn't seem to make a difference.

Hi Bradly,

 

Try this new hotfox: Hotfix Available

The problem I'm sure a lot of us non-techies are having is how do we find out what proxy to enter?????

Does it have something to do with our ISP? Picked from some list on the internet? What???????????

And even if you know what proxy to use (and what port) even with the "hotfix" installed how do you make the prog recognize it?

"Mass deployment," "What Holes to Punch," "Altered Configuration Script," Blah, Blah, Blah!!!!!

A layman's explanation PLEASE!!!!!!

Hi,

Try this:

1. Contact your Internet Service Provider (ISP) in regards to your proxy
2. Install the hotfix
3. Start WWT and click the "Settings" button and enter your Proxy and Port

Further to the user and password problem via proxy's here is the pac script we use, as to whether the user dialog box is web based or program based I haven't been able to get a clear answer from IT helpdesk. Don't know if this info is helpful but at least it confirms what our proxy and port is which when entered into the "hot fixed" WWT still comes up with no internet connection and obviously no prompt for a user name and password.Cheers.

Hi Bradly,

 

Try this new hotfox: Hotfix Available

With this hotfiz WWT complains about missing internet connection with or without the proxy information being provided.

Also with this version I ca change the .config file and WWT continues to complain about missing internet connection.

Jacques

 I have the same issue as a lot of other osters, that is I need to enter a user name and password at the start of each session on IE or Firefox, and WWT doesn't ask.

 As a comparison, I just downloaded and installed Google Earth. It seemd to take the proxy info from somewhere, and when it first starts it asks for my user name and password just like any other internet session. This didn't require any configuation, and in fact in the settings I can't even find the configuriaton/connection/proxy information.

Yes, this is the same situation I am in. Any software on my work pc that wants to access the internet pops up a window asking for login & password *unless* you are able to input the login & password in the configuration settings - so AV etc software does not trigger the popup every time they call home for the daily updates. Browsers, email programmes & other stuff requiring a live connection such as world wide wind & google earth all trigger the popup before they can connect to the big bad internet. Any software that gets its internet link using the IE settings will give you a popup asking for the proxy login & password since these are not inputtable into the IE settings, only the proxy address & port.

It seems to me that in order to get past a proxy that requires verification, WWT will need to trigger this popup so the user can enter login & password. At this stage it is not getting this information and so is trying to get thru' a proxy that requires authentication without presenting any authentication .. naturally enuf the proxy says "nyet" and WWT reports "unable to find an internet connection." Since such a wide range of software does trigger the login popup, including stuff that is not normally "internet active", it's strange that WWT is having such a problem with it .. it may be that WWT's attempt to deal with the proxy server specifically fails with these sorts of proxies? WWT, even without the proxy tweaks that have been suggested, would not seem to be just using the IE settings since other software which use the IE settings have no problems. Maybe an added security feature is backfiring in some cases? I'm only a user, not a programmer, so I'm only making some stabs in the dark here.

Unfortunately I can't get more details on the proxy server used at work ... I'm off on sickleave for a few weeks with pneumonia. :(

Re jacques (I think) and the question of a sandbox .. I've never used one myself but was wondering about maybe setting up a virtual machine which did trigger the proxy popup and running WWT inside that. Not exactly an elegant fix nor probably a desirable one. And probably a non event since hopefully the proxy issue will be fixed before I'm back at work.

cheers, 

David

PS: The proxy popup is not a web page but very similar to the one that pops up when you log onto a pc that's on a network (but without the extra options the login popup has). Dunno if that helps?

cheers,
David

With the "fix" installion downloaded and installed I can now set the proxy details, but WWT still fails to connect. However the rather strange thing is that if I go to the down arrow at the bottom of teh settings tab and select product support... I get a seciond window created by the app which DOES connect to the internet. Whatever mechanism is used here is what is needed to solve the problem. I can select links within this window and they all connect OK. Can this connection mechanism be transferred to the main program?
