speedy quota 1G + winxp(laptop) + squid + bind9 + cache youtube (lanjutan)

Nerusin topik sebelumnya , setelah berhasil bikin proxy pakai squid di winxp, akan di coba nambahin local resolver dns pakai bind9(windows precompile binary).

step pertama, nginstall bind9 di winxp
download precompile bind9 untuk windows di sini:

http://ftp.isc.org/isc/bind9/9.5.0-P2-W2/BIND9.5.0-P2-W2.zip

• extrak di satu folder.
• didalam folder klik 2 kali BINDInstall
• muncul popup windows installer kecil, biarkan semua nya default, kecuali service account password,klik install

tunggu sampai selesai.

hasil instalasi nya nanti akan berada di sini C:\WINDOWS\system32\dns

• klik start -> run -> ketik cmd, cd ke C:\WINDOWS\system32\dns\etc\

– buat file dengan nama named.conf,isinya seperti ini:

acl "trusted" {
     localhost;
     192.168.0.0/16;
};

acl "bogusips" {
     0.0.0.0/8;
     1.0.0.0/8;
     2.0.0.0/8;
     192.0.2.0/24;
     224.0.0.0/3;
     169.254.0.0/16;
};

options {
   allow-transfer { none; };
   allow-query { trusted; };
   allow-recursion { trusted; };
   blackhole { bogusips; };
   directory "c:\windows\system32\dns\etc";
   listen-on { 127.0.0.1;  }; #listen only on localhost
   forwarders { 202.x.x.x; 202.x.x.x; }; #ubah sesuai dns isp masing2
   forward first;
   recursion yes;
};

logging {
   channel queries_log {
       file "c:\windows\system32\dns\etc\queries.log";
       print-severity yes;
       print-time yes;
   };
   category queries { queries_log ; };
};

zone "." {
   type hint;
   file "named.root";
};

zone "localhost." IN {
   type master;
   file "localhost.zone";
   allow-update { none; };
};

zone "0.0.127.in-addr.arpa." IN {
   type master;
   file "localhost.rev";
   allow-update { none; };
};

include "d:\windows\system32\dns\etc\rndc.key";

– masih di directory C:\WINDOWS\system32\dns\etc\

ketik ..\bin\dig.exe @a.root-servers.net . ns > named.root
perintah di atas akan menghasilkan file named.root yg berisi record2 root zone

ketik ..\bin\rndc-confgen.exe -a
perintah di atas akan menghasilkan file rndc.key

ketik copy con localhost.zone , tekan enter, kemudian paste isi zone file ini:

$TTL 86400
@ IN SOA @ root (
       42 ; serial
       3H ; refresh
       15M ; retry
       1W ; expiry
       1D ) ; minimum
IN NS @
IN A 127.0.0.1

tekan tombol ctrl+z

ketik copy con localhost.rev , tekan enter, kemudian paste isi zone file ini:

$TTL 86400
@ IN SOA localhost. root.localhost. (
       1997022700 ; Serial
       28800 ; Refresh
       14400 ; Retry
       3600000 ; Expire
       86400 ) ; Minimum
IN NS localhost.
1 IN PTR localhost.

tekan tombol ctrl+z

– untuk memastikan konfigurasinya sudah benar nggak ada error ketik ini:

..\bin\named-checkconf.exe , kalo gakkeluar warning atau apapun bisa kita asumsikan konfig nyaudah benar.

– saat nya jalanin service bind9, klik start-> run->ketik services.msc->enter, nanti keluar jendela services, cari service yg bernama ISC BIND, select, klik kanan, start.

– setingan ethernet/tcp/ip untuk dns nya jangan lupa di ubah ganti dengan localhost atau 127.0.0.1

sudah siap untuk di coba.

contoh:

ketik ..\bin\dig.exe @127.0.0.1 www.altavista.com ns

hasil output query:

query timenya 109 msec

ketik lagi ..\bin\dig.exe @127.0.0.1 www.altavista.com ns

kali ini hasil querynya 0 msec, sepertinya resolver kita sudah berhasil meng-cache hasil query dns

nah, karena niat kita dari pertama mau semua yg harusnya keluar ke internet di cache di lokal pc atau laptop kita, sekarang tinggal ngubah sedikit config squid supaya memakai lokal dns resolver yg baru kita buat, gampang kok tinggal ngedit TAG dns_nameservers

dns_nameservers 127.0.0.1 # cuma ini aja yg harus di edit

selesai.

step selanjutnya bikin caching youtube

(note: butuh squid versi 2.7 versi lain setau saya nggak bisa karena nggak ada fungsi storeurl_rewrite_program, storeurl_access)

referensi nya saya dapet dari sini:

http://human.network.web.id/2008/06/30/caching-youtube/

( tutorial yg hebat , tutorialnya aslinya buat proxy under linux(penulis juga sudah coba di linux dan berhasil)

sekarang kita akan coba install di winxp

langkah2nya:

karena script untuk me-rewrite url yg kita gunakan berbasis kan perl interpreter kita butuh nginstall interpreter nya, gak masalah download aja di sini:

http://www.activestate.com/Products/activeperl/index.mhtml

install, ikutin aja step2 default nya.

setelah itu masuk ke directory config dimana kita menginstall squid

cd c:\squid\etc\

buat file store_url_rewrite.pl

copy con store_url_rewrite.pl , ketik enter lalu isi data2 ini

#!/perl/bin/perl
$|=1;
while (<>) {
@X = split;
$url = $X[0];
$url =~s@^http://(.*?)/get_video\?(.*)video_id=(.*?)&.*@squid://videos.youtube.INTERNAL/ID=$3@;
$url =~s@^http://(.*?)/get_video\?(.*)video_id=(.*?)$@squid://videos.youtube.INTERNAL/ID=$3@;
$url =~s@^http://(.*?)/videodownload\?(.*)docid=(.*?)$@squid://videos.google.INTERNAL/ID=$3@;
$url =~s@^http://(.*?)/videodownload\?(.*)docid=(.*?)&.*@squid://videos.google.INTERNAL/ID=$3@;
$url =~s@^http://(.*?)/albums\?&.*@squid://images.photobucket.INTERNAL/ID=$3@;
$url =~s@^http://(.*?)/albums\?$@squid://images.photobucket.INTERNAL/ID=$3@;
$url =~s@^http://(.*?)/albums\?&.*@squid://videos.photobucket.INTERNAL/ID=$3@;
$url =~s@^http://(.*?)/albums\?$@squid://videos.photobucket.INTERNAL/ID=$3@;
print "$url\n"; }

tekan ctrl+z

untuk konfig squidnya, squid.conf contoh aja seperti di bawah ini, edit2 sesuai kebutuhan

jangan lupa di save

setelah itu klik start->run->services.msc, rstart services squid

terakhir test browsing salah satu video youtube, untuk pertama kali memang masih di stream langsung dari server youtube.

tutup browser, buka kembali dan arahkan ke url video yg sama di youtube. kalo proses cachingnya berhasil, menurut pengamatan penulis proses load nya sudah dari lokal cache/disk

selesai semua usaha kita untuk mengcaching yg seharus nya kita load directly dari server nya di internet
