Blacklists

In this context, blacklists are set as site lists organized by several categories that are considered inconvenient. You can find here the following options (Figure 4.9):

• Url for update: Address that provides the file download with the list of sites to block - by default this is the squidGuard URL. The file is automatically uncompressed to the system. To update the list click Update;
• Current file MD5SUM: MD5 Hash of the file if it's calculated. It lets you check file integrity;
• Available categories: Categories list present in the compilation (usually they are considered unsuited to LAN use)
  • ads: List of advertisement sites;
  • aggressive: List of violent content sites
  • audio-video: List of music and video content sites;
  • drugs: List of drug related content sites;
  • gambling: List of gambling sites;
  • hacking: List of hacking sites;
  • mail: List of sites that provide free webmail services;
  • phishing: List of sites about phishing;
  • porn: List of sites with pornographic content;
  • proxy: List of sites that provide anonymous proxy service;
  • warez: List of sites with pirate software content

Content access management

Sets the number of simultaneous filtering processes that depends on the machine performance and the present CPU load. The default is five processes.

Proxy cache options

• Cache enabled: Activates the Proxy cache service. If the cache is activated, every page accessed by the origin groups are stored in the server. Example: If the page www.google.pt is in the cache, the browser will only access to IPBrick, instead of accessing the google web server, providing a better band width management.
• Cache size: Maximum cache size. If the limit is reached, the older cache files are removed.
