Pactester is a tool to test Proxy Auto Configuration (PAC) files. PAC files are used by browsers to determine the ‘right’ proxy for a URL. Since the PAC file evaluation mechanism is generated inside the browser and cannot be accessed from outside, the only way to tell which proxy your browser will use for a specific URL is manual inspection of the PAC file. But manual inspection doesn’t really scale very well. Pactester resolves this problem. It makes use of JavaScript interpreter and Netscape/Mozilla APIs to evaluate the PAC files and automates the whole process.
Pactester reads a PAC file, evaluates it in a JavaScript context and uses this PAC file’s logic to determine the proxy for a specific URL.
Usage: ./pactester <-p pacfile> <-u url> [-h host] [-c client_ip]
./pactester <-p pacfile> <-f urlslist> [-c client_ip]
Options:
-p pacfile: PAC file to test
-u url: URL to test
-h host: Host part of the URL
-c client_ip: client IP address (defaults to IP address of the machine on which script is running)
-f urlslist: a file containing list of URLs to be tested.
Example:
./pactester -p wpad.dat -u http://www.google.com
./pactester -p wpad.dat -u http://www.google.com -c 192.168.1.105
./pactester -p wpad.dat -f url_list

Trouble:
Sometimes it happens in windows XP that you are not able to open drives on your hard disk. When you double clicking on the drives icons or right click on the drive>>explore in My computer ,the drive does not open.
This problem is generally caused by most of the viruses which infect windows XP system. They block or restrict your access to any of the drives.
But don’t worry this is not a big trouble it can be fixed easily.
Fix:
Normally when a virus infects a windows system which causes a drive opening problem, it automatically creates a file named autorun.inf in the root directory of each drive.
This autorun.inf file is a read only ,hidden and a system file and the folder option is also disabled by the virus. This is deliberately done by the virus in order to protect itself. autorun.inf initiates all the activities that the virus performs when you try to open any drive.
You have to just delete this file and restart your system to correct this problem.
Follow the set of commands below to show and delete the autorun.inf
1. Open Start>>Run and type cmd and press enter. This will open a command prompt window. On this command prompt window type the following steps.
2. type cd\
3. type attrib -r -h -s autorun.inf
4. type del autorun.inf
5. now type d: and press enter for d: drive partition. Now repeat steps 3 and 4. Similarly repeat step 5 for all your hard disk partition.
Restart your system and your trouble will be fixed.
Update:
If you find the above procedure difficult, the use: Scan and Remove Suspicious ‘autorun.inf’ with Autorun Eater
