NTP berguna untuk menyesuaikan waktu pada pc atau server dengan waktu setempat, dan untuk menghidupkan ntp client daemon pada slackware ada 2 cara yaitu:

dengan mengetikkan

# chmod +x /etc/rc.d/rc.ntpd

atau mengisi pada /etc/rc.d/rc.local dengan

# Start the NTP daemon
#
if [ -x /etc/rc.d/rc.ntpd ]
then
/etc/rc.d/rc.ntpd start
fi

setelah itu kita lakukan membackup dan mengedit pada ntp.conf

# mv /etc/ntp.conf /etc/ntp.conf.bk
# touch /etc/ntp.conf
# pico /etc/ntp.conf

isi dengan (googling... ntp server indonesia)

server 2.id.pool.ntp.org
server 1.asia.pool.ntp.org
server 0.asia.pool.ntp.org

untuk menjalankan pertama kali daemon ntp

# /etc/rc.d/rc.ntpd start
Starting NTP daemon: /usr/sbin/ntpd -g

cek apakah ntp telah berjalan

# ntpq -p
remote refid st t when poll reach delay offset jitter

Setelah mencari dan mencoba... akhirnya saya memberanikan diri untuk menulis tutorial ini...

Menambah user dan group

# groupadd squid
# useradd squid -g squid -d /bin/false -s /nonexistent

Unduh file squid

#wget - b http://repository.slacky.eu/slackware-13.0/network/squid/3.0.STABLE19/squid-3.0.stable19-i486-1sl.txz

Instalsi squid

# installpkg squid-3.0.stable19-i486-1sl.txz

Memberikan permission agar squid dapat diesksekusi

# chmod +x /etc/rc.d/rc.squid

Supaya squid berjalan dengan automatis setelah komputer hidup maka ditambahkan pada # /etc/rc.d/rc.inet2

# Start SQUID (Squid proxy 3.0):
if [ -x /etc/rc.d/rc.squid ]; then
. /etc/rc.d/rc.squid start
fi

Mengubah kepemilikan

access_log:

# touch /var/log/squid/logs/access.log
# chown -R squid.squid /var/log/squid/logs/access.log

cache_log:

# touch /var/log/squid/logs/cache.log
# chown -R squid.squid /var/log/squid/logs/cache.log

cache_store_log:

# touch /var/log/squid/logs/store.log
# chown -R squid.squid /var/log/squid/logs/store.log

pid_filename:

# touch /var/log/squid/logs/squid.pid
# chown -R squid.squid /var/log/squid/logs/squid.pid

squid cache:

# mkdir /var/log/squid/cache/
# chown -R squid.squid /var/log/squid/cache/

Sebelum membuat swap direktori, isi ubah dahulu isi dari /etc/squid/squid.conf

# mv /etc/squid/squid.conf /etc/squid/squid.conf.bk
# touch /etc/squid/squid.conf
# pico /etc/squid/squid.conf

Membuat swap direktori

# /usr/sbin/squid -z

Cek konfigurasi squid sudah benar atau belum

# /usr/sbin/squid -k parse

2010/05/05 10:25:38| Initializing https proxy context

Menjalankan squid pertamakali

# /usr/sbin/squid -sYD

Menjalankan proxy squid

# /etc/rc.d/rc.squid start
Starting Squid: /usr/sbin/squid -DF

Agar dapat diakses melalui Mikrotik sebagai external proxy

#pkgtool
- Pilih setup
- check services
- check rc.ip_forward

Pada /etc/rc.d/rc.local

# iptable squid
iptables -t nat -A POSTROUTING -j MASQUERADE

# transparent proxy
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128

Reboot pc-proxynya... dan selamat mencoba...
