Setting AP (Access Point) Di slackware

AP atau Access Point adalah sebuah metode untuk membagi jaringan, disini saya akan mencoba menjelaskan bagaimana cara membuat Mesin yang sudah terinfeksi dengan SLACKWARE untuk membagi jaringan via wireless adaptor.
bahan bahannya :

1. Hostapd (bisa di compile pake sbo silakan dapatkan slackbuild nya di slackbuilds.org)
2. Sebuah mesin (laptop,netbuk atau apalah itu yang sudah build in wireless adaptor [semua komputer jinjing yang bs wifi-an bs dipake disini]) yang mempunya wireless adaptor. [disini saya menggunakan notbuk saya asus eeepc 1215p dengan slackware-current ]
3. Sebuah client (semua mobile device yang mendukung wifi) [disini saya menggunakan 1 buah bb, dan 1 buah hp nokia e63]

Langsung meracik ramuan nya:

1. Konfigurasi HOSTAPD: Edit berkas /etc/hostapd/hostapd.conf

interface=wlan0 driver=nl80211 ssid=MyHotspot country_code=ID hw_mode=g channel=1 auth_algs=1 ignore_broadcast_ssid=0 wpa=3 wpa_passphrase=test2011 wpa_pairwise=TKIP rsn_pairwise=CCMP

1 2 3 4 5 6 7 8 9 10 11 12

interface=wlan0 driver=nl80211 ssid=MyHotspot country_code=ID hw_mode=g channel=1 auth_algs=1 ignore_broadcast_ssid=0 wpa=3 wpa_passphrase=test2011 wpa_pairwise=TKIP rsn_pairwise=CCMP

Keterangan :
ssid=MyHotspot : silakan MyHotSpot di isi dengan nama sesuka anda
wpa_passphrase=test2011 : silakan ganti dengan password yang anda ingin kan

# dhcpd.conf # # Configuration file for ISC dhcpd (see 'man dhcpd.conf') # option domain-name-servers 208.67.222.222, 208.67.220.220; default-lease-time 600; max-lease-time 7200; ddns-update-style none; ddns-updates off; subnet 192.168.0.0 netmask 255.255.255.0 { range 192.168.0.200 192.168.0.229; option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; option routers 192.168.0.1; }

1 2 3 4 5 6 7 8 9 10 11 12 13 14

# dhcpd.conf # # Configuration file for ISC dhcpd (see 'man dhcpd.conf') # option domain-name-servers 208.67.222.222, 208.67.220.220; default-lease-time 600; max-lease-time 7200; ddns-update-style none; ddns-updates off; subnet 192.168.0.0 netmask 255.255.255.0 {         range 192.168.0.200 192.168.0.229;         option subnet-mask 255.255.255.0;         option broadcast-address 192.168.0.255;         option routers 192.168.0.1; }

2. Start and Stop Hotspot Service: Buat berkas baru dengan nama rc.hotspot di /etc/rc.d
Silakan buat dan edit berkas ini :
# nano /etc/rc.d/rc.hotspot

#!/bin/sh # Script to start/stop a hostapd-based access point # edited for slackware distro # Symbols for needed programs IPTABLES=/usr/sbin/iptables IFCONFIG=/sbin/ifconfig DHCPD=/usr/sbin/dhcpd HOSTAPD=/usr/sbin/hostapd # Symbols for internal and external interfaces NET_INT=wlan0 NET_EXT=ppp0 # IP address for the AP INT_ADDR=192.168.0.1 case "$1" in start) echo "Starting AP mode for $NET_INT at address $INT_ADDR" # Disable packet forwarding echo 0 > /proc/sys/net/ipv4/ip_forward # Stop any existing hostapd and dhcpd daemons killall hostapd killall dhcpd #Set up forwarding $IPTABLES -t nat -A POSTROUTING -o $NET_EXT -j MASQUERADE $IPTABLES -A FORWARD -i $NET_EXT -o $NET_INT -m state --state RELATED,ESTABLISHED -j ACCEPT $IPTABLES -A FORWARD -i $NET_INT -o $NET_EXT -j ACCEPT # Enable packet forwarding echo 1 > /proc/sys/net/ipv4/ip_forward # Get the internal interface in the right state $IFCONFIG $NET_INT down $IFCONFIG $NET_INT up $IFCONFIG $NET_INT $INT_ADDR # dhcpd needs to have a leases file available - create it if needed if [ ! -f /var/state/dhcp/dhcpd.leases ]; then touch /var/state/dhcp/dhcpd.leases fi # Bring up the DHCP server $DHCPD -cf /etc/dhcpd.conf $NET_INT # Bring up hostapd $HOSTAPD -B -P /var/run/hostapd.pid /etc/hostapd/hostapd.conf ;; stop) echo "Stopping AP mode on $NET_INT" # Stop hostapd and dhcpd daemons kill -INT $(cat /var/run/hostapd.pid) kill -INT $(cat /var/run/dhcpd.pid) ;; *) echo "Usage: $0 {start|stop}" exit 1 ;; esac

Jika anda ingin saat booting slackware anda script ini aktif maka masukan ini di rc.local
#nano /etc/rc.d/rc.local

# Start hotspot service if [ -x /etc/rc.d/rc.hotspot ]; then . /etc/rc.d/rc.hotspot start fi

1 2 3 4

# Start hotspot service if [ -x /etc/rc.d/rc.hotspot ]; then . /etc/rc.d/rc.hotspot start fi

Tahap selanjutnya adalah membuat file rc.hotspot menjadi executable dengan cara
#chmod +x /etc/rc.d/rc.hotspot
Jika sudah silakan jalankan hotspot anda
#/etc/rc.d/rc.hotspot start

Selesai
