bookmark_borderGet system load using Python Script

I have written a simple python script that collect system load information and store in a XML file.


#!/usr/bin/env python

import os
import commands
import time
from time import gmtime, strftime

while 0 < 10:

file_name = strftime("%Y_%m_%d_%H_%M", gmtime())

data = commands.getoutput("w | grep load")
xml_data = ""+ data + ""

print xml_data


if os.path.isfile(file_name + ".xml"):
x=0
else:

f_prev=open(file_name + ".xml", 'a')
f_prev.write("")
f_prev.close

f=open(file_name + ".xml", 'w')
f.write("nn")
f.close()


f=open(file_name + ".xml", 'a')

f.write(xml_data+"n")

f.close()
time.sleep(3)

We will get XML file like this.

<?xml version=’1.0′ encoding=’utf-8′?>
<data>
<load> 01:40:38 up 6:27, 3 users, load average: 0.07, 0.07, 0.03</load>
<load> 01:40:48 up 6:27, 3 users, load average: 0.06, 0.07, 0.03</load>
<load> 01:40:58 up 6:27, 3 users, load average: 0.05, 0.07, 0.03</load>
</data>

bookmark_borderSiemens-Sk65 udev script for GPRS

When I use GPRS some times my phone move to ttyUSB0 to ttyUSB1 and it disconnect me.

For the details doc: click here

I just add this in my udev.rules

KERNEL==”ttyUSB*”, BUS==”usb”, SYMLINK+=”siemens-sk65″

then in my wvdial.conf

Modem = /dev/siemens-sk65

bookmark_borderEDGE/GPRS in Linux

Today me (salahuddin66) and Lavluda successfully configured GPRS/EDGE in Linux.

Using wvdial

to check your mobile/modem as a modem
——————————-
#wvdialconf

it will generate /etc/wvdial.conf file for you.

Grameen Phone
For Grameen Phone your need to add

Init3 = AT+CGDCONT=1,”IP”,”gpinternet”

here is a sample of my /etc/wvdial.conf (Grameen Phone EDGE/GPRS)
————————————————————
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,”IP”,”gpinternet”
Modem Type = Analog Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyUSB0
Username = xyz
Password = xyz
Baud = 115200
———————————————————–
wvdialconf will generate the modem speed/Baud and /dev/xyz path according to your mobile phone

Aktel, Teletalk
here is a sample of my /etc/wvdial.conf
————————————————————
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyUSB0
Username = xyz
Password = xyz
Baud = 115200
———————————————————–
wvdialconf will generate the modem speed/Baud and /dev/xyz path according to your mobile phone

Start
To start type wvdial in shell

Note:
If you have problem while generating wvdial.conf file in /etc/wvdial.conf then delete the old config file /etc/wvdial.conf and give wvdialconf to create a new configuraton file.

if you have any problem to find the /dev path for your mobile/modem, give

# tail -f /var/log/syslog

Then connect the phone/modem.
You can also use gnome-ppp or other ppp tools to connect.

Using gnome-ppp

Give phone number *99***1#

click on the detect. it will try to detect your phone/modem.
note: If it fails then give your /dev path manually. Search for you modem using #tail -f /var/log/syslog then connect the phone/modem.

it found my phone/modem in /dev/ttyUSB0

click Init Strings.
for Aktel, Teletalk and others (you do not need to change anything)

click Init Strings.
add Init3 only if you are using Grameen Phone EDGE/GPRS (only for GP)

after click connect

connected

Note: If you face any problem using this as user. Run gnome-ppp as root
or check you are a member of dip group.

In Debian or Ubuntu based distro give #adduser your_user_name dip if your are not a member.
