Squid Lusca on Ubuntu

Lusca bertujuan untuk memperbaiki kekurangan dalam Squid-2. Ini juga mendukung berbagai protokol clustering. Menggunakan lusca, sobat bisa menyimpan beberapa isi yang dinamis yang sebelumnya tidak dapat lakukan dengan squid, seperti :

  1. Video Cachingi.e Youtube / tube etc . . .
  2. Windows Update / Linux Updates / Anti-virus , Anti-Malware i.e. Avira/ Avast / MBAM etc . . .
  3. Download caching mp3’s/mpeg/avi etc . .

Di sebagian dunia, bandwidth sangat mahal, oleh karena itu (dalam beberapa skenario) sangat berguna untuk Cache video Youtube atau flash video lainnya, sehingga jika salah satu dari pengguna download video / file flash, mengapa lagi pengguna yang sama atau lainnya tidak dapat men-download file yang sama dari CACHE, mengapa ia harus internet untuk konten yang sama lagi n lagi?

jika mengalami kendala dalam copas code tersebut,
download filenya di link ini
[xt_go_advt_1] setelah selesai jalankan perintah dibawah #/temp/lusca_install.sh tunggulah sampai prosesnya selesai, setelah selesai #squid -d1n #ps aux |grep squid ##hasilnya seperti gambar dibawah

Squid Lusca on Ubuntu

Jika hasilnya sudah seperti diatas, maka sobat sudah berhasil membuat sebuah server proxy, langkah berikutnya sobat melakukan setting router untuk mengarahkan LAN ke proxy tersebut.

Demikian tutorial Cara Konfigurasi Squid Lusca on Ubuntu semoga bermamfaat, jika ada pertanyaan silahkan tinggalkan pesan di kolom komentar.
