Installation and Upgrades / Dans guardian is failing to block https://www.facebook.com

« on: February 03, 2011, 11:24:56 am »

Hi,

My Dans guardian is able to block a user from accessing http://www.facebook.com.  Some clever users on my network are able to bypass it by just typing https://www.facebook.com.  How do I block this?

I don't want to block https as a whole but just the specific facebook site.  My email is using https.

Thanks

Installation and Upgrades / Content Encoding Error The page you are trying to view cannot be shown

Please kindly assist.  I get the error message below whenever I try to http://us.mg4.mail.yahoo.com/

Content Encoding Error. The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. Please contact the website owners to inform them of this problem.

No other user on the network can access their yahoo email.  We have tried Firefox, IE and google chrome to no avail. Could it be my proxy settings?

Thanks in advance.

Installation and Upgrades / Enforce clients to use the proxy server

« on: July 09, 2010, 10:04:39 am »

I notice that a client using firefox is able to bypass the proxy server by choosing "use system proxy settings" under network configuration settings.  A client can disable the manual proxy server configurations and be able to browse without any limitations.

In ebox, I enabled "transparent proxy" to try and force the clients to use ebox.  Ebox tells me "Transparent proxy option is not compatible with authorization policy." I think this is because my default policy  which is "Authorize and filter."

How do I solve this problem? Thanks.

Hello everyone,

I notice ebox 1.42 now has bandwidth throttling.  Any suggestions about how I would use it for a 40-computer network with a bandwidth of 2Mbps?

Hi,

I'm able to send out emails to any email address internally and externally.  Unfortunately, I cannot receive any emails from external domains.  I'm using egroupware.  Which configuration setting could I have missed?
