comment out (#) the “*** Slaves ***” section
comment out or remove everything below “*** Targets ***” > remark (don’t remove probe, menu, title)
You’ll need to add your targets before you can do anything useful with smokeping.

mkdir -p /var/www/html/smokeping/img
chown -R apache:apache /var/www/html/smokeping/img
mkdir /usr/local/smokeping/var
/usr/local/smokeping/bin/smokeping &

Visit http://some.url/cgi-bin/smokeping.cgi in a web browser and check that you’re not getting an error 500 (check your SELinux config).

Optional SmokeTrace install & configure:

Instalasi Squid High Performance

2009-07-07T05:58:00.000-07:00

kangmas hari ini nginstal proxy buat warnet pelanginet, kangmas pakai os debian ....
Langkah awal yang perlu disiapin antara lain :
1. Cemilan
2. Air buat minum
3. Rokok bagi yang merokok tapi kangmas ndak merokok.

kemudian.
Berikut adalah langkah-langkahnya :
1. download duluw paket squid di : http://squid-cache.net
# useradd squid
# groupadd squid
# cd /home/kangmas
# wget http://www.squid-cache.org/Versions/v2/2.7/squid-2.7.STABLE6.tar.gz

2. kemudian extrak file yang telah didownload
# tar -zxvf squid-2.7.STABLE6.tar.gz

3. kemudian konfigure dengan perintah dibawah ini
# cd squid-2.7.STABLE6
# ./configure \
--prefix=/usr/local/squid \
--enable-async-io \
--enable-removal-policies=lru,heap \
--disable-delay-pools \
--disable-wccp \
--enable-kill-parent-hack \
--enable-snmp \
--enable-linux-netfilter \
--disable-auth
4. kemudian di make
# make
# make all
# make install

5. masuk ke direktori
# cd /usr/local/squid/etc

6. ubah nama file squid.conf yg asli
# mv squid.conf squid.conf.asli

7. download squid.conf
# wget http://geocities.com/danangyanto/Linux/squidconfig.txt

8.edit isi file squidconfig.txt nya sesuaikan dengan konfigurasi network anda
#mv squidconfig.txt squid.conf
ubah permission di directori cache dan direktori dimana anda meletakkan cache.log dengan memberikan kepemilikan terhadap squid

untuk mengetahui tempat access.log tersebut gunakan perintah berikut:
# grep access.log squid.conf
cache_access_log /squid/var/logs/cache.log

dr output grep di atas access.log terdapat pada /squid/var/logs/cache.log
maka ubahlah pemiliknya menjadi squid
# chown -R squid.squid /usr/local/squid

berikan kepemilikan direktori squid kepada squid
# chown -R squid.squid /usr/local/squid/var/cache

menjalankan pertama kali squid
# /usr/local/squid/sbin/squid -z
Jalankan perintah ini untuk mengaktifkan squid
# /usr/local/squid/sbin/squid -sYD

Untuk perbaharui isi file squid tanpa hrs menghentikan squid ketika squid masih aktif, cukup jalankan perintah :
# /usr/local/squid/sbin/squid -k reconfigure

Jangan lupa jalankan Squid dari startup..agar Running setiap PC dihidupkan
contoh buat debian :)
# echo "/usr/local/squid/sbin/squid -sYD" >> /etc/rc.local

Fisnish deh !..tinggal konfigurasi aja ke masing2 client dgn alamat proxy IP Address proxy server dan portnya.

*) Bila mau kostumisasi lagi untuk kebutuhan lainnya..silahkan dicoba sendiri dgn membaca informasi ttg squid.
