Mengenal Squid Proxy Warnet

Jasa setting Mikrotik - Squid adalah sebuah daemon yang digunakan sebagai proxy server dan web cache. Squid memiliki banyak jenis penggunaan, mulai dari mempercepat server web dengan melakukan caching permintaan yang berulang-ulang, caching DNS, caching situs web, dan caching pencarian komputer di dalam jaringan untuk sekelompok komputer yang menggunakan sumber daya jaringan yang sama, hingga pada membantu keamanan dengan cara melakukan penyaringan (filter) lalu lintas.





Meskipun seringnya digunakan untuk protokol HTTP dan FTP, Squid juga menawarkan dukungan terbatas untuk beberapa protokol lainnya termasuk Transport Layer Security (TLS), Secure Socket Layer (SSL), Internet Gopher, dan HTTPS. Versi Squid 3.1 mencakup dukungan protokol IPv6 dan Internet Content Adaptation Protocol (ICAP).

Squid pada awalnya dikembangkan oleh Duane Wessels sebagai "Harvest object cache", yang merupakan bagian dari proyek Harvest yang dikembangkan di University of Colorado at Boulder. Pekerjaan selanjutnya dilakukan hingga selesai di University of California, San Diego dan didanai melalui National Science Foundation. Squid kini hampir secara eksklusif dikembangkan dengan cara usaha sukarela.

Squid umumnya didesain untuk berjalan di atas sistem operasi mirip UNIX, meski Squid juga bisa berjalan di atas sistem operasi Windows. Karena dirilis di bawah lisensi GNU General Public License, maka Squid merupakan perangkat lunak bebas.

To configure the BlackBerry Desktop Manager to use the BlackBerry smartphone as a tethered modem, complete the following steps:

1. In the main menu of the BlackBerry Desktop Manager, click IP Modem.
2. During the initial BlackBerry smartphone connection, complete the configuration step by clicking the Configure button.
3. Select the Set-Up Connection option from the Connection profile drop-down list.
4. Select the appropriate wireless service provider or select Add customer profile for custom settings.
