Issue/Introduction

When trying to download Firefox (or posibly other vendor) patches the files are only about 2 KB in size

In order to confirm this collect a wireshark trace while downloading a firefox bulletin.  Add the following filter in wireshark:  "http contains firefox"  then review the trace for the following behavior:

 

*****http request****

Environment

Windows 2012 R2

Websense installed.

Cause

Websense blocks the Firefox files from downloading. In one case Websense allowed the Firefox files to download through a browser but would block Altiris. Patch Management tries to download Firefox patches from locations like the following:

http://releases.mozilla.org/pub/mozilla.org/firefox/releases/50.1.0/win64/en-US/Firefox%20Setup%2050.1.0.exe
http://releases.mozilla.org/pub/mozilla.org/firefox/releases/50.1.0/win32/en-US/Firefox%20Setup%2050.1.0.exe

Websense redirects to:
http://xx.xx.xx.xx:15871/cgi-bin/blockpage.cgi?ws-session=393137511

 

Resolution

Change the Websense settings so the files can be downloaded.
