When you’re in the consulting business, you travel a lot between companies. That what I consider the beautiful part of the job. Downside is that every company has it’s own policy for Internet usage. A lot of companies regulate their internet access through so called proxy servers. When you visit a lot of companies you have to change the internet settings multiple times a day to match the desired settings for that company. Therefore I wrote a powershell script that detects the DNS suffix of the company you’re at and matches the proxy settings according to the configured settings read from a XML file.
What does the script do:
- Change Proxy Server settings for Internet Explorer and Chrome
- Add Proxy Exceptions to bypass the proxy
- When connected to multiple networks a known location takes presence
- When a location is not known, the configuration defaults to “Direct Connection”
- Notifies you which settings are used.
What the script does NOT do:
- Detect networks based on IP Address (Never will, too general way of checking)
- Change Proxy settings for FireFox (#1 on my wishlist)
- Detect network changes dynamically.
Copy the PS1 and XML to a convinient location (eg. C:\Windows). Configure the XML file for use with proxy servers. Each location must be in its own <Sites> node.
<Name> The name for your location is must be in the Name node.
<DNSDomain> The DNS Domain that should be checked is in this node
<ProxyServer> In this node you enter the proxy server name
<ProxyPort> In this node you enter the proxy port that should be used
<ProxyOverRide> All exceptions that should bypass the proxy server are entered in this node, each exception should be separated with a semi column.
<Sites> <Name>My Location</Name> <DNSDomain>company-a.com</DNSDomain> <ProxyServer>www-proxy.company-a.com</ProxyServer> <ProxyPort>8080</ProxyPort> <ProxyOverRide>intranet.company-a.com;dev.company-a.com;</ProxyOverRide> </Sites>
Each location should look like the above example, you can append multiple sites to the <Global> node. I’ve tested the script on Windows 7 (x64) but it should work on Windows XP as well. to hide the Powershell command-box you can start the powershell script with:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -WindowStyle “Hidden” C:\Windows\SetProxy.ps1
I’ve created a scheduled task that executes the script on login and unlock, that covers it for me. additionaly you can create a shortcut on your desktop to launch the script manually.
Please let me know what you think.
