Koneksi dengan menggunakan pppsetup (Slackware)

Skrip ppp setup merupakan skrip yang dibuat oleh ROBERT S. LIESENFELD dan disertakan hampir di setiap distribusi Slackware. Untuk memanggilnya cukup ketikkan pppsetup dengan account root.
$ su #pindah ke account root 
password: 
# pppsetup

Segera akan muncul layar pppsetup Versi 1.98, informasi pembuatnya dan kegunaannya. Tekan Enter. Pertama kali adalah permintaan untuk mengetikkan nomor telepon ISP yang akan dihubungi. Misalnya :
atdt3524001 <- untuk menelpon dengan tone 
atdp3524001 <- untuk menelpon denga pulse

Selanjutnya tekan enter, dan masuk ke penentuan modem.
Pilih ttys0 jika modem Anda disambungkan ke port Com1 
Pilih ttys1 jika modem Anda disambungkan ke port Com2 
Pilih ttys2 jika modem Anda disambungkan ke port Com3 
Pilih ttys3 jika modem Anda disambungkan ke port Com4

Setelah menentukan modem, dilanjutkan dengan menentukan baudrate dari modem.
460800 untuk modem dengan kecepatan 460KBps - Modem ISDN 
230400 untuk modem dengan kecepatan 230KBps - Modem 56KBps atau ISDN 
115200 untuk modem dengan kecepatan 115KBps - Modem 56KBps atau 33.6 atau 28.8 
57600 untuk modem dengan kecepatan 57.6KBps - Modem 56KBps atau 33.6 atau 28.8 
38400 untuk modem dengan kecepatan 38.4KBps - Modem 56KBps atau 33.6 atau 28.8 
19200 untuk modem dengan kecepatan 19.2KBps - Modem ISDN 
57600 untuk modem dengan kecepatan 9.6KBps - Modem ISDN

Pilih sesuai konfigurasi modem Anda. Selanjutnya akan muncul pertanyaan :
Does your service provider provide call back?

Jawab no. Call back adalah fasilitas yang memungkinkan server untuk menelepon kembali beberapa saat setelah login. Pertanyaan selanjutnya adalah tentang init string dari modem. Tekan enter langsung dan biarkan pppsetup memasukkan nilai standar.
Konfigurasi selanjutnya adalah nama domain dari ISP. Misal; indosat.net.id, telkom.net.id dan sebagainya. Isikan nama domain ini, diikuti dengan nomor IP dari DNS Name Server ISP. Jika Anda tidak yakin, tanyakanlah pada ISP Anda. Lalu akan ditanyakan metode autentikasi, pilih PAP. Dua konfigurasi terakhir adalah username dan password Anda untuk login ke ISP. Semua input yang diisikan selama setup ini akan disimpan dalam satu file yang berada di/etc/ppp/pppsetup.txt (minus username dan password untuk login ke ISP). Berikut contoh filenya :

connect "/usr/sbin/chat -v -f /etc/ppp/pppscript"

If you have a ethernet connection you should change the local:remote

IP addresses in the options.demand file, to your actual local and

remote address. Example: 215.346.117.89:312.217.187.96

# This in your /etc/resolv.conf file.

search cbn.net.id

nameserver 202.158.3.7

202.158.3.7 <-IMPORTANT: This should be the IP address of

your service providers nameserver.

# This is your /etc/ppp/pap-secrets file.

Look at /etc/ppp/pap-secrets.

Does everything look correct? if not, run 'pppsetup' again...

===============================================================

To connect to your service provider.

===============================================================

# ppp-go <-Make PPP connection.)

You'll hear and see the modem dialing then once connected,
logging you in Username: or Login: and Password: etc.

You won't see a Username or Login: and Password: prompt

if they're using PAP or CHAP to authenticate you.

If they use PAP or CHAP you'll just see CONNECT - got it.

If the connection was successful you'll see the Local IP and

Remote IP address printed to the screen, you can press [Enter].

If you run ppp-go in X windows you probably won't see a Local

and Remote IP address printed to the screen, you'll just see

the connection process come to a end, wait a few seconds and

press [Enter] at that point.

If you don't connect for whatever reason e.g. Failed No

Dialtone, Busy, No Carrier, Whatever, Exit, just press

[Enter] at that point.

if you have syslogd running, you can see the output messages

from pppd and chat in the /var/log/messages and or debug file.

Sample /var/log/messages file.

spawn pppd[562]: Serial connection established.
spawn pppd[562]: Using interface ppp0

spawn pppd[562]: Connect: ppp0 <-> /dev/modem

spawn pppd[562]: local IP address 215.87.78.18

spawn pppd[562]: remote IP address 205.94.97.35

You don't have a successful PPP connection until you

receive a local & remote IP address like above.

If you have the X window system, you could connect in a Xterm.

spawn # startx

spawn # ppp-go

spawn # netscape mosaic etc.

# ppp-off <-To end the ppp connection.)

# ppp-go -h <-For help.)

There is no support in linux for "WinModems", if you have a

WinModem you will not be able to use it in linux.

There is support for plug n play modems, if you have a pnp

modem you may need "isapnptools" to get it recognized.
