Found a modem on /dev/ttyS1.



Lakukan konfigurasi wvdial.conf

[Dialer Defaults]
Modem = /dev/ttyS1
Baud = 115200
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 S11=55 +FCLASS=0
Phone = 080989999
Username = telkomnet@instan

Password = telkom

jalankan wvdial

[userdrake@migration-team ~]# wvdial

setelah komputer terkoneksi biasanya komputer nya akan mendapatkan DNS di /etc/resolve.conf dan routing gateway telkom itu artinya komputer anda sudah bisa browsing,

Untuk menshare ada beberpa tahapan konfigurasi lagi.

Aktifkan forward ipv4

[userdrake@migration-team ~]# vi /etc/sysctl.conf

ipv4_forward = 1 ( aktif , default=0 )

agar network local dapat melakukan routing ke ppp0 ( disini kunci agar jaringan komputer kita dapat sharing internet

[userdrake@migration-team ~]# iptables -t nat -A POSTROUTING -s 10.60.254.0/24 -o ppp0 -j MASQUERADE
