Please help me setup my internet connection


I am using RH Fedora 4 on my COMPAQ AMD based processor. I am having a Reliance (PPP) Internet. The modem is built into the phone, and i dont have driver for it. Hope it works for generic driver. It is connected to the COM1 (ttyS0) of my PC. Can anybody please provide me information on how to configure my internet on my linux m/c so that i can use on Linux platform. Please tell me the procedure to configure.
I dont have the IP addr of DNS sever, as it is not provided by the ISP.

Revision History

Revision 1.0 2005-06-21

Revised by Machtelt Garrels for inclusion in TLDP.





This document explains how to set up and configure Reliance or TATA Indicomm

WLL phones on Linux, using a serial cable instead of the (default) USB cable.

It also has instructions on how to build the cable yourself.

1. Introduction



This HOWTO is for people who have Reliance or TATA Indicomm WLL phones and

wish to access Internet on their desktops/laptops running GNU/Linux using

serial cable (NOT a USB CABLE).



No software provided by Reliance was used, but I did search the Internet for

the modem query strings which are required during PPP setup.



I have tried this setup on Slackware Linux 10.1 with a 2.4.29 kernel and I am

pretty confident that this trick will work on other Linux distributions as

well.



The HOWTO assumes that you have a fair knowledge about your Linux

distribution (BSD or System V style) and that PPP support is pre-compiled in

your Linux kernel.



In this HOWTO we are talking about the serial cable for the following

reasons:



1. The cable provided by Reliance or TATA is very expensive (about 1400

rupees) and the software provided supports only MS Windows.The cable

typically has a USB interface on one end and an RJ-45 interface on the

other. However, for these phones phones a cheaper cable is available on

the market (only 100 rupees). This cable has a serial interface on one

end and an RJ-45 on the other. You can make this cable yourself. The

procedure is discussed later in this HOWTO. Why waste money when you can

assemble your own cable or purchase the cheaper one?



2. USB cables have some glitches for the WLL handsets, especially the LG

ones. I have no idea about other handsets, your input is welcome if you

know about other sets. The advantage in using a USB cable is that you can

connect at 153.6 kbps as the handsets have an inbuilt modem which is

capable for speeds upto 170kbps.



3. On the numerous forums I searched on the net I found that all talked only

about the USB cable and not about the serial one. I thought it was high

time to write this HOWTO to help fellow Linux users.





Note But I have a USB cable!

If you have the USB cable after all, visit [http://www.hackgnu.org/

ril-howto.html] http://www.hackgnu.org/ril-howto.html for information

about setting up Internet access using LG/SAMSUNG CDMA sets.



This link is also helpful: [http://www.linuxsolved.com/forums/

ftopic1178.html] http://www.linuxsolved.com/forums/ftopic1178.html



Unfortunately the LG/SAMSUNG CDMA mobile uses USB cables only, but the

good news is that these USB cables are also available on the market.

Purchase them at your local computer vendor's. As per my last

information such cables cost only 200 rupees.

-----------------------------------------------------------------------------



2. System Requirements



You will need a GNU/Linux system with a kernel having PPP support

pre-compiled. I have tested that both the 2.4.29 kernel and the 2.6.x series

kernel work fine. Performance seems to be better using a 2.6.x kernel. If you

see that some kernel modules are missing then configure and recompile the

kernel with PPP support.



Check with Section 4 for the configuration of PPP.



A connecting serial cable which has on one end an RJ-45 connector which plugs

into the phone and on the other end has an RS-232 serial connector which is

plugged into the serial port of the PC.



I built my cable myself. I used a CAT 5 cable which has four pairs of UTP

copper. CAT 5 cable is the same cable which is used for networking your

system to a LAN. While you can use any type of cable, CAT 5 will assure a

good quality of the signal that is sent over the wire. A typical

configuration looks like this:



RS-232C Serial Female connector, which is plugged into the PC:

___________________

\ /

\ 5 4 3 2 1 /

\ 9 8 7 6 /

\___________/







Now let's start with the PIN Configuration



* PIN 1 - White Brown cable



* PIN 2 - Blue cable



* PIN 3 - White Green cable



* PIN 4 - Green cable



* PIN 5 - White Blue cable



* PIN 6 - Brown cable



* PIN 7 - White Orange cable



* PIN 8 - Orange cable



* PIN 9 - Leave empty (we are only using 8 pins)





Note Serial connection details

Three strings would be enough for a serial connection, but it turned out

that the signal is better when you use 5. The other strings are used for

extra rigidness and support of the cable.



Now on to the RJ-45 connector, which is plugged into the WLL Phone RJ-45

jack:

[8 7 6 5 4 3 2 1]

----

-



* 1 - White Orange



* 2 - Orange



* 3 - White Green



* 4 - Blue



* 5 - White Blue



* 6 - Green



* 7 - White Brown



* 8 - Brown





Tip How to hold the connector

If you are confused as to which way to hold the connector, make sure that

you are holding the connector in such a way that its notch pin is facing

towards the floor and that the open portion (portion from where the wires

enter) is facing away from you.

-----------------------------------------------------------------------------



3. Activating Internet Services on your Handset



To get Internet services activated on your handset you may contact the

customer care center of your service provider. In the case of the Reliance

the service is pre-activated.



For establishing the connection on a Reliance, the user name is the phone

number without the prefix 0 in the STD code. For instance, if your STD code

is 0124 and telephone number is 3456789 then your user name is 1243456789.

Your password is the same as your user name. When using the TATA Indicomm

user name and password are "internet" (without quotes).

-----------------------------------------------------------------------------



4. Checking for PPP Support



Although PPP support is provided in almost all Linux distributions but it is

still better to check whether it is present on your system. You can use

checkconfig or, better still, look into the /usr/sbin directory and locate

PPP binaries with the command



ls -al ppp*



If you get a listing like this:

-rwxr-xr-x 1 root root 3438 2005-05-28 14:56 ppp-go*

-rwxr-xr-x 1 root bin 1787 2004-02-26 21:36 ppp-off*

lrwxrwxrwx 1 root root 6 2005-05-28 14:17 ppp-on -> ppp-go*

lrwxrwxrwx 1 root root 7 2005-05-28 14:17 ppp-stop -> ppp-off*

-rwxr-xr-x 1 root bin 346812 2004-02-26 21:36 pppd*

-rwxr-xr-x 1 root bin 37916 2004-02-26 21:36 pppdump*

-rwxr-xr-x 1 root bin 25936 2003-03-02 22:05 pppoe*

-rwxr-xr-x 1 root bin 22308 2003-03-02 22:05 pppoe-relay*

-rwxr-xr-x 1 root bin 35084 2003-03-02 22:05 pppoe-server*

-rwxr-xr-x 1 root bin 12028 2003-03-02 22:05 pppoe-sniff*

-rwxr-xr-x 1 root bin 58527 2004-02-26 21:36 pppsetup*

-rwxr-xr-x 1 root bin 9192 2004-02-26 21:36 pppstats*



then PPP support is definitely present.



Similarly, look into /etc/ppp directory, which contains the PPP options file

and some other files configuring PPP:

-rw------- 1 root root 78 2004-02-26 21:36 chap-secrets

-rw------- 1 root root 1625 2005-05-28 14:35 connect-errors

-rw-r--r-- 1 root root 938 2003-03-02 22:04 firewall-masq

-rw-r--r-- 1 root root 836 2003-03-02 22:04 firewall-standalone

-rwxr-xr-x 1 root root 1208 2005-05-28 14:56 ip-down*

-rwxr-xr-x 1 root root 1208 2005-05-28 14:29 ip-down.OLD*

-rwxr-xr-x 1 root root 1945 2005-05-28 14:56 ip-up*

-rwxr-xr-x 1 root root 1945 2005-05-28 14:29 ip-up.OLD*

-rw------- 1 root root 541 2005-05-28 14:58 options

-rw------- 1 root root 656 2005-05-28 14:56 options.demand

-rw-r--r-- 1 root root 9975 2005-05-28 11:21 options.old

-rw------- 1 root root 216 2005-05-28 14:56 pap-secrets

drwxr-xr-x 2 root root 4096 2003-03-02 22:05 plugins/

-rw-r--r-- 1 root root 104 2003-03-02 22:04 pppoe-server-options

-rw-r--r-- 1 root root 4562 2003-03-02 22:04 pppoe.conf

-rw------- 1 root root 129 2005-05-28 15:12 pppscript

-rw------- 1 root root 8941 2005-05-28 14:56 pppsetup.txt



For the sake of safety do copy your original options file to a file

options.old so that you can revert back to your original setup should you

have troubles.



See [http://www.tldp.org/HOWTO/PPP-HOWTO/...guration.html] the PPP

HOWTO Chapter 10 for more information on PPP support in the Linux kernel.

-----------------------------------------------------------------------------



5. Configuring your Phone



Currently Reliance comes with one of two brands of handsets: LG and Samsung.

TATA Indicom also provides two handsets: LG and AXESSTEL.



Plug the cable to the phone and also to the system.



It is important to note that all these phones act as a serial modem so they

do not require a driver or anything. After you have connected your phone to

the cable, the cable is plugged in either COM1 or COM2 (and not COM3 or COM4,

as these are virtual ports).



Remember:



* COM1 in LINUX is /dev/ttyS0



* COM2 is LINUX is /dev/ttyS1





Your phone modem works on either of the two ports, but I suggest that first

try /dev/ttyS1, so as not to disturb other peripherics on your system that

are also using a serial port, which would then usually be on /dev/ttyS0.



First check if your COM port is fine using the command



setserial /dev/ttyS1 -a



If it displays something like this:

dev/ttyS1, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3

Baud_base: 115200, close_delay: 50, divisor: 0

closing_wait: 3000

Flags: spd_normal skip_test





then your COM port is fine. If this does not work, it is possible that PPP

support is not configured after all. Return to Section 4 to check. If you are

sure that PPP support is configured on your system, maybe the problem is with

the COM port. You could try the other port in that case.



Now go to the shell and type



cat /dev/ttyS1



If this prints nothing, your phone is configured. Type CTRL+C to exit.



If your modem is not configured, the cat command would give an error message

like this:

cat: /dev/ttyS1: No such device



Alternately, in case you use KDE, start the KPPP program: go to the desktop

and press Alt+F2 and type "kppp" in the box which appears. This will start

KPPP.



Testing using KPPP:



Click on the Configure button. Go to the Modem tab.

There add a new modem on /dev/ttyS1and click OK. Now select the newly created

modem and click the EDITbutton. In the new box which appears, select Modemand

then click Query modem. If the modem is properly set then you will get the

proper status of the modem. It will first say something like "Finding Modem",

then some more messages.



Warning Lock file

BE SURE TO UNCHECK THE USE LOCK FILE CHECKBOX in the modem

properties, else it may give some random errors.



If all is fine you will be presented with a window with some blank textboxes

and you can go ahead.

-----------------------------------------------------------------------------



6. PPP Configuration



Make an easy link to your modem device:



ln -s /dev/ttyS1 /dev/modem



Now change to the /usr/sbin directory and look for ppp files. Look for either

a pppsetup or a pppconfig script. You may directly start this script to set

up PPP on your system. On my Slackware system I typed pppsetup and started

the script. This script asks for various parameters for connecting via the

ISP.



* It first asks for the phone number to dial -- enter "atdt#777", where 777

is replaced by the number that you need to dial.



* It then asks for the modem -- select /dev/ttyS1



* Baud Rate -- select "115200"



* Callback -- Answer "NO"



* Modem INIT String -- "ATZ OK "at+crm=1" OK"



* ISP Domain Name -- Leave blank



* DNS Server Address -- Enter a valid DNS Server IP, for instance

"202.41.97.3" or "202.41.97.132", or leave blank



* Authentication -- "PAP"



* Username



* Password





Refer to Section 3 for Username and Password.



Finally it shows you your configuration.



Some more work needs to be done. We need to edit the options file present in

the /etc/ppp folder. We need to check if the following entries are present in

the file:

lock

defaultroute

noipdefault

modem

/dev/ttyS1

115200

crtscts

noauth

passive

asyncmap 0



Note The noauth option

Remember that noauth is by default commented; you need to uncomment it.



You can use egrep -v '#|^ *$' /etc/ppp/options to list only the options

present in this file so as to quickly judge which ones are missing or

incorrect.

-----------------------------------------------------------------------------



7. Let's Get Started



For testing purposes log in as root and open two different shells.



In one shell issue the command



tail -f /var/log/messages



Start the PPP connection in the other shell using the command



ppp-on



In the first shell you will see various messages indicating that the modem is

initialized and that the connection is being established. My /var/log/

messages looks like this:

May 29 06:14:06 dhiraj pppd[2341]: pppd 2.4.2 started by root, uid 0

May 29 06:14:07 dhiraj chat[2343]: timeout set to 60 seconds

May 29 06:14:07 dhiraj chat[2343]: abort on (ERROR)

May 29 06:14:07 dhiraj chat[2343]: abort on (BUSY)

May 29 06:14:07 dhiraj chat[2343]: abort on (NO CARRIER)

May 29 06:14:07 dhiraj chat[2343]: abort on (NO DIALTONE)

May 29 06:14:07 dhiraj chat[2343]: send (ATZ^M)

May 29 06:14:07 dhiraj chat[2343]: expect (OK)

May 29 06:14:07 dhiraj chat[2343]: ATZ^M^M

May 29 06:14:07 dhiraj chat[2343]: ^M

May 29 06:14:07 dhiraj chat[2343]: at+crm=1^M^M

May 29 06:14:07 dhiraj chat[2343]: OK

May 29 06:14:07 dhiraj chat[2343]: -- got it

May 29 06:14:07 dhiraj chat[2343]: send (atdt#777^M)

May 29 06:14:07 dhiraj chat[2343]: timeout set to 75 seconds

May 29 06:14:07 dhiraj chat[2343]: expect (CONNECT)

May 29 06:14:07 dhiraj chat[2343]: ^M

May 29 06:14:07 dhiraj chat[2343]: atdt#777^M^M

May 29 06:14:07 dhiraj chat[2343]: CONNECT

May 29 06:14:07 dhiraj chat[2343]: -- got it

May 29 06:14:07 dhiraj pppd[2341]: Serial connection established.

May 29 06:14:07 dhiraj pppd[2341]: Using interface ppp0

May 29 06:14:07 dhiraj pppd[2341]: Connect: ppp0 <--> /dev/ttyS1

May 29 06:14:13 dhiraj pppd[2341]: PAP authentication succeeded

May 29 06:14:13 dhiraj kernel: PPP BSD Compression module registered

May 29 06:14:13 dhiraj kernel: PPP Deflate Compression module registered

May 29 06:14:14 dhiraj pppd[2341]: local IP address 220.224.45.140

May 29 06:14:14 dhiraj pppd[2341]: remote IP address 97.235.2.5



Now open your browser and get started.



In case the browser gives the error that the server name is not being

resolved, open the file /etc/resolve.conf and add the entry

namesserver 202.41.97.9

nameserver 202.41.97.132





These are two valid DNS servers of Ernet India Labs, located in New Delhi.

Your Internet Service Provider probably provides its own name service, use

the IP addresses of the servers they recommend.



When you are finished surfing the net you may stop the connection using



ppp-off



in the second shell. In the other shell window you will get something like

this :

May 29 06:16:15 dhiraj pppd[2341]: Terminating on signal 2.

May 29 06:16:15 dhiraj pppd[2341]: Connection terminated.

May 29 06:16:15 dhiraj pppd[2341]: Connect time 2.2 minutes.

May 29 06:16:15 dhiraj pppd[2341]: Sent 3401 bytes, received 1563 bytes.

May 29 06:16:16 dhiraj pppd[2341]: Connect time 2.2 minutes.

May 29 06:16:16 dhiraj pppd[2341]: Sent 3401 bytes, received 1563 bytes.

May 29 06:16:16 dhiraj pppd[2341]: Exit.





Stop the messages output using Ctrl+C.
