anyone can help me setup wvdial

[nolo]

hi fellow linux

I new to linux <still learning>
I am currently using slackware 13.1 32bit
and i have been all over the forum
looking for solution to how to connect the cellc 3g card

i currently have wvdial as it was the only software
available after searching internet for connection manager

I even installed wine hoping that i could run the windows
network manager to only find out that the is some
DLL netsomthing.dll missing

any help will be welcomed

I on slackware cuz i want to learn how to develop software

First off you need to leave the mxit speak out...
It just makes it a lot more difficult trying to understand where you at and
what exactly you trying to do! :)

Trying to connect using wvdial and a 3g modem on linux will typically involve 2 or 3 files:

1) Script file that powers up/down the modem
2) /etc/network/interfaces where network interfaces are defined
3) /etc/wvdial.conf where you setup dial rules

Here is a snippet of wvdial.conf:


[Dialer 3G]
Modem = /dev/ttyACM1
Init1 = AT+CGDCONT=1,"IP","internet"
Stupid mode = 1
phone = *99#
username =;
password =;

You need to define the device where your modem can be reached in linux
as well as APN settings and user/pass on that apn.

In the /etc/network/interfaces file you may define a 3g interface:


# 3G interface - ppp
iface 3g inet wvdial
pre-up . /usr/local/etc/F3507g; ifup F3507g; python /opt/ServiceAssure/F3507g.py ppp
provider 3G

Note the pre-up script calls to turn on the modem in this case an F3507g ericcson modem.
provider 3g is the dialer config within the wvdial.conf file.

And now you can connect with the command "ifup 3g" and similarly calling "ifdown 3g"
will stop the connection.

@udiS3 thz for the reply

1) Script file that powers up/down the modem
2) /etc/network/interfaces where network interfaces are defined
3) /etc/wvdial.conf where you setup dial rules


do i need to code 1) or are the scripts on the net i can grab?

2) is this done with through pppd?

3) APN settings and user/pass on that apn? do i need to call cellc to get hold of this settings?

[@udiS3]

Nolo,

1) Here you want to talk to the modem on it's control channel and power it up and optionally
unlock the sim for use. This is done by using commands from the modem's AT command set.
Most commands will work with most modems! But there are variations between modems so it
would be wise to find the AT command set for the modem you are using.

Try to find a script that someone has written already for your modem would make life much easier
for you!

However you could just as well modify an existing script to make it compatible with your modem. An
easy way to check commands is to run them using the linux chat command...

As an example here is a snippet of my script file (F3507g):

CONTROL_DEVICE="/dev/ttyACM1"
PIN="0000"
APN="internet"


bringupsim() {
if [ -c "/dev/sim" ]
then
echo "sim device exists"
else
echo "creating sim"
mknod /dev/sim c 251 1
echo O > /dev/sim
fi
}

powerup_F3507g () {
echo -n "Powering up F3507g card.."
while [ ! -c $CONTROL_DEVICE ]; do sleep 0.5; echo -n "."; done
echo "done"
echo -n "Turning on F3507g card..."
sleep 3
echo "bringing up sim"
bringupsim
sleep 3
echo "bringing up modem with SIM active"
/usr/sbin/chat -v "" "AT+CFUN=1,1" "+PACSP1" > $CONTROL_DEVICE < $CONTROL_DEVICE
sleep 12
/usr/sbin/chat -v "" "AT+CPIN?" "SIM PIN" "AT" "OK" "AT+CPIN=\"$PIN\"" "OK" > $CONTROL_DEVICE < $CONTROL_DEVICE
sleep 6
/usr/sbin/chat -v "+PACSP1" > $CONTROL_DEVICE < $CONTROL_DEVICE
echo "done"
}

powerdown_F3507g () {
echo -n "Turning off F3507g card..."
/usr/sbin/chat -v "" "AT+CFUN=4" "OK" > $CONTROL_DEVICE < $CONTROL_DEVICE
echo "done"
}

You can test the chat commands to see if they work individually!


2) This is a text file on your machine that defines the system network interfaces.


3) For Vodacom/mtn the settings are:
apn: internet
username and password blank or guest.
I assume Cell C would be the same?

@udiS3

I got hold of usb_switch from this site http://www.draisberghof.de/usb_modeswitch/#intro
the are few people who are using the same modem in other countries so will be using their settings....
i will google number two and see how far i can get to have internet on slackware

[nolo]

@udiS3

usb_switch works and the settings for wvdial work what i need now is to setup network interface

@udiS3

Awesome! Go ahead and edit the /etc/network/interfaces file with any text editor...
As an example:

# 3G interface - ppp
iface 3g inet wvdial
pre-up . /usr/local/etc/F3507g; ifup F3507g;
provider 3G

The first line states that the interface is managed by wvdial and the last line specifies that
the 3G dialer from wvdial.conf should be used.

[nolo]

/etc/network/ does not exist in my slackware 13.1
/etc/rc.d/ seems to be the file that exist when i google the internet
for /etc/network

[nolo]

This is what happens when i run wvdial
since i did not do step 2

Sure its easy. Load Ubuntu or even better...Linux Mint :-)

Seriously though...cant help you with that wvdialer thing. I have never understood that thing. Read up on it a bit but after thirst few lines I got a headache and left it. :-)

[nolo]

slack is my first linux i know that ubuntu is easy, but would not be happy
after getting so close to make something work. To only give up on it, then what was
the point of trying...

besides i don't think linux is difficult if it was well documented ... with easy step by step
most people would be able to setup 3g modems on their linux distro

thanks for all your help my linux finally has internet
