Using UMTS/GPRS USB stick

[thenktor]

Hi,

did somebody already use UMTS sticks in Salix/Slackware?
One of my friends says it works out of th ebox in Ubuntu via Gnome NetworkManager. Another possible solution might be umtsmon (but it uses qt3). Perhaps there are better options for Salix? I'm not keen on building NetworkManager just for this task.

One sentence at the beginning: I am no scripter, I never had an education in computing, I only try to make things work. Feel free to change it to your needs!

You can use wvdial, comgt and a bash script to connect UMTS-modems.

Here a script, which uses zenity, gtkdialog, wvdial and comgt (I assume, all packages are installed in your system) ... it is the english one, a german script is available too. It is part of fluxflux-sl (Slackware based system with Openbox) and has been part of fluxflux-eee and fluxflux-se (PCLinuxOS remaster). It is running without problems for many users since more than two years.

Copy this /etc/wvdial.conf to /etc/ (as root in a terminal), this is a configuration file for o2, the last lines (do NOT remove the last 4 lines) are needed for the script and will be reconfigured with the correct values for your provider within the script and with your personal input (AP, user, password):

Code: Select all

[Dialer Defaults]
Modem = /dev/ttyUSB0
ISDN = off
Modem Type = USB Modem
Baud = 460800
Init = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init4 = 
Init5 = 
Init6 = 
Init7 = 
Init8 = 
Init9 = 
Phone1 = 
Phone2 = 
Phone3 = 
Phone4 = 
Dial Prefix = 
Dial Attempts = 1
Dial Command = ATM1L3DT
Ask Password = off
Auto Reconnect = off
Abort on Busy = off
Carrier Check = on
Check Def Route = on
Abort on No Dialtone = on
Stupid Mode = off
Idle Seconds = 0
Init3 = AT+CGDCONT=1,"IP","webmobil1"
Password = o2
Username = o2
Phone = *99#

Then copy this script (called umts-connect) to /usr/local/bin/ and make it executable with "chmod a+x /usr/local/bin/umts-connect" and run a "ldconfig":

Code: Select all

#!/bin/bash
#
# umts-connect 0.3
#
# Script to connect UMTS modems
# via comgt (PIN activation) and wvdial
#
# - icon with established connection
# - used volume is shown after the connection is closed
# - choice of the device (modem, handy via usb or bluetooth

The script will connect all Huawei UMTS modems, an icon will be shown in the panel and after closing the connection the used traffic will be displayed.

You can use the UMTS modem directly or a connection via bluetooth or USB connected handy.

My friend has bought one of these sticks now. As he needs something simple to use, I've installed qt3 and umtsmon. I've added his user to the dialout group and and I've done setui root for the umtsmon tool:

Code: Select all

chown root:dialout umtsmon
chmod +s umtsmon
chmod 754 umtsmon

And I had to do a small hack for resolv.conf:

Code: Select all

rm /etc/resolv.conf
ln -s /etc/ppp/resolv.conf /etc/resolv.conf

Everything works fine now. All he has to do is starting the umtsmon tool. It shows signal strenght, connection type (gprs/umts) and traffic.
