.
Program Yang Dibutuhkan adalah
Mikrotik + Squid box
topologi jaringan adalah sebagai berikut :
inet -- cisco --hub -- Squid (slackware) -- mikrotik (bw managr) -- client
......................|
......................|
......................|-- server lain nya
IP ADDRESS SESUAIKAN DENGAN YANG DI MILIKI
blok ip yang di dapat adalah : 202.152.100.0/24
syarat dasar pemahaman :
1. ip subnetting
2. perintah dasar linux
3. perintah dasar mikrotik
Langkah2...
1. Liat ip address cisco nya (asumsi menggunakan FO)
ip address cisco s0/0 202.152.30.1
netmask 255.255.255.252
gateway 202.152.30.2
(biasanya di dapat dari ISP yang di atas isp kita)
2. Memecah blok ip address yang kita dapat :
sebelum blok ip address yang kita miliki kita gunakan ada baik nya di pecah dulu. pada contoh berikut akan saya berikan untuk di bagi menjadi 2. BLOK IP SERVER dan blok ip CLIENT.
BLOK IP SERVER2 :
network : 202.152.100.0/28
ip yang dapat di gunakan :202.152.100.1 - 202.152.100.14
broadcast : 202.152.100.15
BLOK IP CLIENT :
selain yang di atas adalah ip yang dapat di gunakan untuk client.
3. SET IP ETHERNET CISCO
set ip cisco ethernet0/0
ip address : 202.152.100.1
netmask 255.255.255.240
4. setting Proxy server + TUNE UP :
Linux yang di gunakan adalah SLACKWARE 9 dapat di download di :
http://mirror.vip.net.id/pub/slackware/
yang di gunakan adalah :
komputer P4
HARD DISK 40 G seagate baracuda 7200 rpm 3 keping dengan RAM 2 G
keping hardisk pertama di mount ke /
keping hardisk ke 2 di mount ke /cache1
keping hard disk ke 3 di mount ke /cache2
setelah di install isikan ip address berikut :
interface eth0
ip address : 202.152.100.2
netmask 255.255.255.240
gateway 202.152.100.1
Interface eth1
ip address : 202.152.100.17
netmask 255.255.255.252
setelah itu ...
buka file : type.h
root@proxy:~# vi /usr/include/bits/types.h
edit bagian ini :
#define __FD_SETSIZE 1024
jadi seperti ini
#define __FD_SETSIZE 8192
==> kemudian keluar dari VI EDITOR
kemudian ketik perintah ini :
root@proxy:~# ulimit -HSn 8192
kemudian download squid 2.5.STABLE9 dari sini :
wget http://202.154.183.7/squid-2.5.STABLE9.tar.gz
simpan di direktori /usr/local/src
ekstrak dengan perintah :
tar -zxvf squid-2.5.STABLE9.tar.gz
masuk kedirektori squid
ketik perintah berikut ini :
./configure \
--prefix=/opt/squid \
--exec-prefix=/opt/squid \
--enable-gnuregex \
--enable-async-io=30 \
--with-aufs-threads=30 \
--with-pthreads \
--with-aio \
--with-dl \
--enable-storeio=aufs \
--enable-removal-policies=heap \
--enable-icmp \
--disable-wccp \
--enable-snmp \
--enable-cache-digests \
--enable-default-err-languages=English \
--enable-err-languages=English \
--enable-linux-netfilter \
--disable-ident-lookups \
--disable-hostname-checks \
--enable-underscores
karena udah ada mikrotik untuk bw management tidak di perlukan lagi delay pool. Konfigurasi ini adalah untuk komputer dengan spek seperti berikut :
HARDISK 3 keping 40 G seagate baracuda 7200 rpm, RAM 2 G
2 keping hard disk untuk cache, 1 keping untuk system. apabila menggunakan hard disk scsi --enable-async-io=30 --with-aufs-threads=30 bisa di naekkan jadi 32.
==> selesai install squid. semua file squid akan terletak di direktori /opt/squid
setelah itu gunakan squid.conf di bawah ini :
Code:
http_port 8080

no_cache allow youtube

perhatikan ip address yang di izinkan. sesuaikan dengan ip yang di gunakan.
perhatikan juga penggunaan cache direktori. maksimal untuk 1 keping adalah 18 Giga.
setelah itu tambahkan user squid di linux :
root@proxy:~# useradd squid
tambahkan juga group squid
root@proxy:~# groupadd squid
bentuk direktori cache di squid :
root@proxy:~# /opt/squid/sbin/squid -z
ketik perintah ini sekali lagi :
root@proxy:~# ulimit -HSn 8192
kemudian jalankan squid dengan perintah :
root@proxy:~# /opt/squid/sbin/squid -DY &
================================================== ==============
okeee.. kita lanjut :
5. Setting mikrotik :
masukin ip address ether 1 :
/ip address add address=202.152.100.18/30 interface=ether1
karena seluruh ip yang di gunakan adalah ip public maka perlu subnetting di pisah-pisah :
masukin ip address untuk pasangan ip client :
misalkan ip client adalah 202.152.100.22 maka yang di masukkan di mikrotik ethr2 adalah 202.152.100.21/30
demikian pula untuk pasangan ip client2 yang lain.
/ip address add address=202.152.100.21/30 interface=ether2
untuk lebih jelasnya dapat di liat pada tablel berikut :
Code:

kemudian masukan gateway nya ke arah proxy :
/route add gateway=202.152.100.17
atur route di proxy agar mengizinkan network end mikrotik dapat lewat :
route add -net 202.152.100.20/30 gateway 202.152.100.18
selesai urusan ip address...
6. dapat di uji coba client
menggunakan ip address :
202.152.100.22
netmask 255.255.255.252
gateway 202.152.100.21
karena menggunakan subnetting selain ip address 22 tidak akan dapat melewati router mikrotik yang di buat
7. iptables di proxy
semua traffic harus di paksa lewat proxy server yang kita buat dengan perintah :
Code:
iptables -A PREROUTING -t nat -p tcp -s 202.152.100.0/24 -i eth2 -d \! 202.152.100.0/24 --dport 80 -j REDIRECT --to 8080
9. DNS SERVER
jalankan dns server yang telah ada secara defaul di slackware dengan perintah :
root@proxy:~# named -d1
tinggal masukin di /etc/resolv.conf
nameserver 127.0.0.1
dan seluruh client pake dns ip 202.152.100.17
TANPA NAT/MASQUERADE .................. ip public terdistribusi ke client
Selesai ....

Salut boss...
memusingkan tapi berguna banget lho..
