Agar bisa internetan di Slackware dengan modem tentunya kita harus install dulu paket atau aplikasinya. Aplikasi yang penulis sarankan adalah WvDial. WvDial ini berbasis text/CLI, bisa untuk GSM maupun CDMA. Slackware yang digunakan Slackware 14.1.
Paket yang dibutuhkan:
-
WvStreams
-
WvDial
Kita akan unduh dari sini
WvStreams :
-
Slackbuild : http://slackbuilds.org/slackbuilds/14.1/libraries/wvstreams.tar.gz
-
Source code : http://wvstreams.googlecode.com/files/wvstreams-4.6.1.tar.gz
WvDial :
-
Slackbuild : http://slackbuilds.org/slackbuilds/14.1/network/wvdial.tar.gz
-
Source code : http://slackbuilds.org/slackbuilds/14.1/network/wvdial.tar.gz
Kemudian masuk ke /usr/local/src
# cd /usr/local/src
Kemudian salin slackbuild wvstream dan wvdial ke direktori ini (/usr/local/src).
Yang harus diinstall dahulu adalah wvstreams. Ekstrak slackbuild wvstream
# tar -xzf wvstreams.tar.gz
Akan muncul direktori wvstreams pindahlah ke direktori ini. Salin source code wvstreams ke direktori wvstreams kemudian ekstrak di direktori ini
# tar -xzf wvstreams-4.6.1.tar.gz
Setelah itu, beri slackbuildnya hak eksekusi dan jalankan slackbuildnya
# chmod +x wvstreams.SlackBuild && ./wvstream.SlackBuild
Kemudian akan terbuat file installer wvstreams-4.6.1-i486-1_SBo.tgz di /tmp. Nama file ini mungkin tidak sama untuk Anda, silahkan disesuaikan, kalau arsitektur komputer yang Anda gunakan 64 bit maka i486 ganti X86_64.
# installpkg /tmp/wvstreams-4.6.1-i486-1_SBo.tgz
Install wvstreams selesai. Sekarang lanjut install wvdial. Caranya sama seperti install wvstreams. Yaitu:
Scanning your serial ports for a modem.

Found a modem on /dev/ttyUSB0. Modem configuration written to /etc/wvdial.conf. ttyUSB0: Speed 9600; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0” ttyUSB2: Speed 9600; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0”
Kemudian kita atur file konfigurasinya di /etc/wvdial.conf
[Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Modem = /dev/ttyUSB0 Phone = 0 Idle Seconds = 300 Modem Type = Analog Modem Stupid Mode = 1 Compuserve = 0 Baud = 9600 Auto DNS = 1 Dial Command = ATDT Ask Password = 0 ISDN = 0 ; Password = ; Username =
Berikut ini adalah konfigurasi wvdial penulis dengan ISP 3 modem Huawei E1550.

[Dialer 3data] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Init3 = AT+CGDCONT=1,“IP”,“3data” Modem = /dev/ttyUSB0 Phone = 0 Idle Seconds = 300 Modem Type = USB Modem Stupid Mode = 1 Compuserve = 0 Baud = 9600 Auto DNS = 1 Dial Command = ATDT Ask Password = 0 ISDN = 0 Password = 3data Username = 3data New PPPD = yes Phone = 99**1#
Untuk menjalankannya
wvdial 3data
Nah, kalau keluar output seperti ini berarti sudah ada tanda-tanda konek.

Loh kok disebut tanda-tanda konek? Kan di situ udah jelas ada tulisan **CONNECT** ,... ya karena ternyata
ping google.com
ping: unknown host google.com
buat nge-ping aja gagal apalagi browsing!
Oke, kalau terjadi seperti itu, salin aja /etc/ppp/resolv.conf ke /etc/resolv.conf
cp /etc/ppp/resolv.conf /etc/resolv.conf
Coba ping lagi
ping google.com
