  1. FILTERING SYSTEMS AT FILTERING SYSTEMS AT SCHOOL SCHOOL

  2. NEW TECHNOLOGIES NEW TECHNOLOGIES REACH SCHOOLS REACH SCHOOLS � In the last few years computers are becoming more powerful and much cheaper. � We have got Internet connection of good quality. � Windows helps the user. � Computing is reaching more and more people. � Using new technologies has to become a basic tool in the learning proces of children. � THE INFORMATION AND COMMUNICATION SOCIETY IS HERE.

  3. THE NORMAL SITUATION THE NORMAL SITUATION

  4. FIRST GOAL: CONNECTING FIRST GOAL: CONNECTING Proxy: can store the resources used in the centre: web sites, video files, images, sound.....

  5. PROXY (STORE) � � SQUID SQUID PROXY (STORE) Squid is a high-performance proxy caching server for web clients, supporting FTP, gopher, and HTTP data objects.

  6. Summary � � Classroom Models Classroom Models Summary Classroom with a with a Classroom We can find out the “history” Proxy Proxy Squid (Free) Proxy Server (Comercial) Classrooms without without Classrooms Poxy Poxy

  7. SECOND GOAL: MONITORING SECOND GOAL: MONITORING We can find out the “history” in the use of Internet by every computer

  8. REPORT � � CALAMARIS CALAMARIS REPORT Calamaris generate reports in html……

  9. Squid quid A Analysis nalysis R Report eport S Generator enerator � � SARG SARG G It’s a tool that allows you to view "where" your users are going to on the Internet. Sarg generates reports in html SHOWING USERS, IP ADDRESSES, BYTES, SITES AND TIMES.

  10. THIRD GOAL: FILTERING THIRD GOAL: FILTERING Now we want to create lists with forbidden Web sites, the black lists.

  11. BLOCK ACCESS � � SquidGuard SquidGuard BLOCK ACCESS SQUIDGUARD works with SQUID to block SquidGuard access to sites by DOMAIN, IP ADDRESS OR EVEN KEYWORDS . It is very flexible, even allowing you to block access at certain times of day and allow it at others, and even to define groups within your organization that have different access privileges.

  12. SUMMARY � � TOOLS TOOLS SUMMARY Linux or Linux or Operative System System Operative Unix Unix Squid Squid Caching proxy proxy server server Caching Calamaris, Calamaris, Analysis Report Generator Analysis Report Generator Sarg Sarg SquidGuard SquidGuard Block access access to to sites sites Block Blacklist Blacklist

  13. ADVANTAGES ADVANTAGES • School School personalized personalized filter filter • • Zero Zero cost cost for software licences for software licences • • Control ntrol of of the the visited visited using using the the “web” “web” • Co We can filter: We can filter: Non adequate contents contents (pornography, (pornography, Non adequate violence, drugs) violence, drugs) Indiscriminate downloads downloads (programmes, (programmes, Indiscriminate music, videos) music, videos) Activities ( ( icq,msn..) icq,msn..) Activities

  14. INCONVINIENTS INCONVINIENTS Linux is a “young” operative system system Linux is a “young” operative You need “ a little” knowledge about need “ a little” knowledge about You computing computing
