Linux - HOWTO (With Stats)

[!!DV!!]

Hi, I did go thru most of this thread, I got my 3G Novatel U630 working in Suse 9.3 with Kinternet with out to much hassel... Didn't even look at wvdial.

Inserted the card went to YAST and configured it as a modem with a second provider.
add a few strings in config file.

Hey !!DV!! Just Murphys law isn't it? Would you mind posting the config changes you made?

Tazz, How do I go about using AT+CSQ to get a signal strength output?

[!!DV!!]

Sorry for the delay was very busy this week will post configs shortly...

[!!DV!!]

Here we go...

Insert Card (nothing happend ...no beep, no lights..)
restart pcmcia (rcpcmcia restart)

Open Yast, go to Network Devices.... next to Modem...
It is detected as a AT Modem.. Click on cofigure...
Go theu the motions as normal...
Phone number *99***1# any username and no password..

Config files...
/etc/sysconfig/network/
ifcfg-modemX (X is a number asigned by Yast to config file)
BOOTPROTO='none'
DIALCOMMAND='ATDT'
DIALPREFIX=''
DIALPREFIXREGEX=''
INIT1='ATZ'
INIT2='AT Q0 V1 E1 S0=0 &C1 &D2 +FCLASS=0'
INIT3='AT+CSQ' #### Report signal strength see below....
INIT8='ATM0'
INIT9=''
MODEM_DEVICE='/dev/ttyS0'
NAME='AT Modem'
PPPD_OPTIONS=''
PROVIDER='provider1'
SPEED='115200'
STARTMODE='manual'
UNIQUE='Fyby.KM1shMXflFC'
USERCONTROL='yes'

/etc/sysconfig/network/providers/
provider1
ASKPASSWORD='no'
AUTODNS='yes'
DEMAND='no'
DSLSUPPORTED='no'
IDLETIME='300'
ISDNSUPPORTED='no'
MODEMSUPPORTED='yes'
MODIFYDNS='yes'
PASSWORD=''
PHONE='*99***1#'
PROVIDER='VodaFone'
STUPIDMODE='no'
USERNAME='internet'

After all this you select the correct modem fron list by right click on Kinternet Icon and then dail...
then click on view log you will see something similar to this

Hey agent,

I still need to do some work on the AT+CSQ command and how to work it nicely...I am thinking of something like - show_signal.sh which will report something like:

4/5 - Good Signal, enjoy the speed

Laterz !!!

[jbad]

When wireless providers refer to i.e. 64k, do they mean 64 kilo bits or 64 or kilobytes, can someone please assist.

[Tazz_Tux]

Hey jbad,

Normally kilobits

Laterz !!!

[jbad]

Thanks, so I presume if they say up to 1MB to refer to mega bits?

Hello Everyone,

I use this "quick-and-dirty" script to show usage under Linux. I am sure it can be made better, but it was a 2 min job. I have this in my cron jobs that calcs usage for the day, then rotates the log.

I have added a line to my /etc/syslog.conf:

*.*                /var/log/all.log

Restart syslog after that. I also have debugging on in /etc/ppp/options:

debug
kdebug 4

calc_usage.sh

#!/bin/bash
cat /var/log/all.log | grep pppd | grep Sent | gawk -F\  '{print $7"+"}' | xargs > /tmp/sent
echo "0" >> /tmp/sent
echo -n "Sent Total : " && cat /tmp/sent | xargs | bc
cat /var/log/all.log | grep pppd | grep Sent | gawk -F\  '{print $10"+"}' | xargs > /tmp/recv
echo "0" >> /tmp/recv
echo -n "Recv Total : " && cat /tmp/recv | xargs | bc
rm -rf /tmp/sent
rm -rf /tmp/recv

Demo:

localhost tests # ./calc_usage.sh
Sent Total : 9891729
Recv Total : 10027875

Enjoy !!!

[ic]

Excellent, will give it a bash .

[rsachoc]

give it a bash

Pun intended?

[ic]

Pun intended?

Yep .

[Tazz_Tux]

Hello All,

i have just made a new version of the script - It will now keep track of the sessions in a file, easy to view easy to manage.

You can also edit the first three lines to make it work for you

Enjoy !!!

calc_usage.sh

#!/bin/bash

logfile="/var/log/all.log"
tempfile="/tmp/logs"
datafile="/tests/data_usage"

cat $logfile | grep pppd | grep Sent > $tempfile
cat $datafile >> $tempfile

cat $tempfile | grep pppd | grep Sent | sort | uniq > $datafile

cat $datafile | gawk -F\  '{print $7"+"}' | xargs > /tmp/sent
echo "0" >> /tmp/sent
echo -n "Sent Total : " && cat /tmp/sent | xargs | bc
cat $datafile | gawk -F\  '{print $10"+"}' | xargs > /tmp/recv
echo "0" >> /tmp/recv
echo -n "Recv Total : " && cat /tmp/recv | xargs | bc
rm -rf /tmp/sent
rm -rf /tmp/recv
rm -rf $tempfile
