How can you setup PAC files to use SOCKS proxies with authentication?
Using this simple PAC file as an example:
function FindProxyForURL(url, host) { return "SOCKS 69.123.133.75:7257;"; }
How would you connect to that socks proxy using a username and password?
PAC files can be configured manually in browser settings or automated using the Web-Proxy Auto Discovery (WPAD) protocol. The WPAD protocol uses DHCP or DNS to locate the PAC file. The browser used in endpoints searches for a web server on startup to find the PAC file's location.
The proxy auto-config file defines how web browsers and other user agents can automatically choose the appropriate proxy server (access method) for fetching a given URL. user_pref("network. proxy. autoconfig_url", "http://us2.indexdata.com:9005/id/cf.pac");
A proxy auto-configuration (PAC) file is a text file that instructs a browser to forward traffic to a proxy server, instead of directly to the destination server.
A Proxy Auto-Configuration (PAC) file is a JavaScript function definition that determines whether web browser requests (HTTP, HTTPS, and FTP) go direct to the destination or are forwarded to a web proxy server.
Since firefox and msie do not support socks 5 authentication, it is impossible to specify the username and password in a PAC file without first modifying your browser of choice.
