Step 3: Download and Compile Celliax

To build celliax on Linux you need to install ALSA-dev libs

You can do it on Debian/Ubuntu with:
# apt-get install libasound2-dev
You can do it on Fedora/CentOS with:
# yum --nogpgcheck -y install alsa-lib-devel

# cd /usr/src
# wget http://www.gsmopen.org/sites/default/files/chan_celliax.tgz
# tar xvf chan_celliax.tgz
# cd chan_celliax
# make clean
# make

--edit and copy celliax.conf in the asterisk configuration
directory
--copy ciapalo (or your program that accepts text in stdini) in
the location defined in celliax.conf (sms_receiving_program)
--edit modules.conf and put noload in front of *BOTH* chan_oss.so
AND chan_alsa.so AND chan_console.so
--copy asound.conf in /etc/asound.conf

For more info refer README of chan_celliax

Thats it restart asterisk and u have celliax working !!!

Installing Festival and setting voice to female

Filed Under: General

First you need to install festival package

# aptitude install festival festival-freebsoft-utils

In a terminal:

Test festival:
# echo "Hello World"| festival --tts

To copy to wav:
# echo "Hello World" | text2wave -o Hello_World.wav

To read man pages of cron:
#man cron | festival --tts

To read a saved file:
#festival --tts snort-usage.odt

To change voice to a female:

#cd /usr/share/festival/voices/english

#wget http://festvox.org/packed/festival/latest/festvox_cmu_us_slt_arctic_hts.tar.gz
#tar xvf festvox_cmu_us_slt_arctic_hts.tar.gz
#mv festival/lib/voices/us/cmu_us_slt_arctic_hts .

Check if the female voice is loading

#festival

Festival Speech Synthesis System 1.95:beta July 2004
Copyright (C) University of Edinburgh, 1996-2004. All rights reserved.
For details type `(festival_warranty)'
festival> (voice_cmu_us_slt_arctic_hts) <== Set Voice

cmu_us_slt_arctic_hts

festival> (SayText "this is a test text for demo") <== Hear the voice
#<Utterance 0xb7216598>
festival>

If it works,

PHPAGI for asterisk uses text2wave which is a script based on Festival.

text2wave can be set to the voice using

#text2wave -eval "(voice_cmu_us_slt_arctic_hts)"

so a wrapper script is created in /usr/local/bin/text2wave
#!/bin/bash
/usr/bin/text2wave -eval "(voice_cmu_us_slt_arctic_hts)" "$@"

this script will give sometimes "Segmentation fault"
so a replacement of text2wave is taken from http://irlp.kc6hur.net/downloads/text2wave
and copied to /usr/bin
(this one is bug-fixed version)

You have a successfully change the voice!
phew!

Steps to install the zabbix server on ubuntu

Filed Under: General

Prerequisites to install zabbix server:

    Intended for Zabbix 1.6.5 on Ubuntu Feisty Fawn 7.04
    Install pre-requisites:
    Apache
    MySQL-Server
   PHP5
   Net-Snmp libraries

$ sudo aptitude install build-essentials mysql-server php5 php5-gd snmp

libsnmp9-dev snmpd

1 - Make the zabbix user and group:**

$ sudo adduser zabbix

enter in new password

confirm

use the remaining defaults.

Add zabbix to the admin group

$ sudo adduser zabbix admin

2 - Download and Untar the sources:

$su - zabbix

$ wget http://internap.dl.sourceforge.net/sourceforge/zabbix/zabbix-1.4.tar.gz

$ tar zxvpf zabbix-1.4.tar.gz

3 - Create a zabbix database and populate it:

$ mysql -u root -p

$ create database zabbix;

$ quit;

$ mysql -u root zabbix -p < /home/zabbix/zabbix-1.4/create/schema/mysql.sql

$ mysql -u root zabbix -p < /home/zabbix/zabbix-1.4/create/data/data.sql

4 - Configure, compile and install the server:

$ cd zabbix-1.4/

$ ./configure --prefix=/usr --with-mysql --with-net-snmp \

--enable-server --enable-agent &&

$ make

$ sudo checkinstall

5 - Prepare the rest of the system:

$ sudo nano /etc/services

Add at the end:

zabbix_agent 10050/tcp # Zabbix ports

zabbix_trap 10051/tcp

Save and exit.

$ Sudo mkdir /etc/zabbix

$ sudo chown -R zabbix.zabbix /etc/zabbix/

Server=127.0.0.1

Edit /etc/zabbix/zabbix_server.conf:

nano /etc/zabbix/zabbix_server.conf

For small sites this default file will do, however if you are into tweaking your config for your 10+ hosts site, this is the place.

Change this:

# Database password

# Comment this line if no password used

DBPassword=Secret

Start the server :

zabbix_server

Start the client:

zabbix_agentd &

Installation of karl3 in ubuntu

Filed Under: General

Download and Installation

As of the 3.0 release, KARL is relatively straightforward for both developers and evaluators to download and install. In particular, there is no installation for Windows. See the FAQ for an explanation and suggestion.

Note

Note: The most up-to-date installation information is in the developer installation page and the README.txt that comes in the software.

Prerequisites for Evaluation

To get KARL running quickly as an evaluation, you can skip many of the steps used in deployment. Before getting started, make sure you have the following setup.

Python 2.5.x. While you can use a Python package installed by your system, we HIGHLY recommend that you build your own Python. Make sure you include SSL support in the Python.
Subversion. You need a way to check out the KARL software from the repository and keep it up to date.
virtualenv (optional but recommended). Use Python’s easy_install to install virtualenv and isolate it from changes in your Python configuration.
Converters (optional but recommended). Indexing content in PDF, Word, etc. requires some add-on packages. Look in the software’s README.txt for more detail. This is optional and can be done after an installation of KARL.

Installation for the Impatient

Want to see what’s involved before reading the developer installation instructions or the README.txt? Here are the immediate steps to get a running KARL.

svn co http://osi.agendaless.com/bfgsvn/karlsample/trunk/ karl3
cd karl3
/path/to/your/python/bin/virtualenv --no-site-packages .
bin/python ./bootstrap.py
bin/buildout -U
Wait a number of minutes while lots of work is done.
download and install repoz.bfg.formish.
bin/supervisord
Visit in your browser: http://localhost:6543/ and login as username admin and password admin
When finished: bin/supverisorctl shutdown

Webalizer Report Generating

Filed Under: General

Step 1: login to the particular website server (eg. Mahiti.org at 192.168.x.x)

$ ssh username@hostname

Step 2: After loggen in to above server, go to apache2 folder as below:

$ cd /var/log/apache2

Step 3: execute below command to open all access.log files and find the mentionded website (mahiti.org) in all the access.log files and store in a file (linweb)

$cat access.log access.log.1 | grep mahiti.org >> linweb

Step 4: create a script file to sort the linweb file

the final file will be in jumbled time format. Webalizer stops when it reaches todays date. As a result dont forget to sort the final file so that the webalizer analyzes all the entries

$sudo vi sort.sh

Step 5: copy the below text into newly created (sort.sh) script file then save & exit.

#!/bin/sh
if [ ! -f $1 ];
then
echo "Usage: $0 "
exit
fi
echo "Sorting $1"
sort -t ' ' -k 4.9,4.12n -k 4.5,4.7M -k 4.2,4.3n -k 4.14,4.15n -k 4.17,4.18n -k 4.20,4.21n $1 > $1.sorted

Step 6: to see the content of the file (linweb) type the below command, which is still not sorted.

$ vi linweb

$ ls -l

Step 7: run the following command to change the permission level of sort.sh file.

$ chmod 775 sort.sh

Step 8: run the following command to sort the linweb file.

$ ./sort.sh linweb

Note: the above command will create a file a sorted file as below.

linweb.sorted

Step 9: to see the sorted contents in the linweb file

$ vi linweb.sorted

Step 10: to generate a webalizer report run the following command.

$ webalizer linweb.sorted

$ ls -ltr

Step 11: run the following three commands only if webalizer application is not installed on your computer. If already installed then go to step 12 directly from step 10.

$ sudo aptitude update

$ sudo aptitude install webalizer

$ webalizer linweb.sorted

Step 12: create a folder to store the webalizer report.

$ sudo mkdir lin

Step 13: run the following webalizer command to generate & store the webalizer report into newly created folder (lin)

$ webalizer linweb.sorted -o lin/

Step 14: go to new (lin) folder and see the contents stored (there will be around five files)

$ cd lin

$ ls

Step 15: run the following command to see the webalizer report index.

$ lynx index.html

Step 16: now copy the newly created folder (i.e lin) to your computer for futher use.

$ sudo scp -r lin user@hostname:/location/location/location/.

Note: Here "linweb" & "lin" are the just examples only, you can use any name you want.

Printing

Filed Under: General

Printing

Most printers will be automatically supported by Ubuntu. The Printer Configuration application allows you to add printers, as well as modify their settings. You can also use this application to share the printer with other computers on a network, disable the printer, or restart it.

Local Printing

A local printer is one which is directly connected to your computer (as opposed to a network printer, discussed in the following section).

To setup a new local printer, plug your printer into your computer and power it on. Most printers will automatically be detected and configured. Once detected, a printer icon will appear in the notification area and after waiting a few moments, you should get a popup with the text Printer added.

If your printer was not detected after a few moments, then you will need to follow these steps:

Obtain the model name of your printer.
Ensure the printer is turned on.
Choose System → Administration → Printing
Click New Printer.
Your printer should be automatically detected. If so, simply click Forward and then Apply.
Finally, you can enter in a description and location for your printer.

If your printer was not automatically detected, you can try to select the port and printer driver manually. Some printers need further setup. Search the databases at LinuxPrinting.org or check the Ubuntu Wiki Printer page for information on your printer.

Network Printing

You can also configure your Ubuntu system to send print jobs to a remote print server. Remote printers are hosted somewhere on a network. To configure a remote printer:

Obtain the model name of your printer.
Ensure the printer is turned on.
Choose System → Administration → Printing
Choose New Printer.
If your printer is directly connected to a Windows machine on your network, choose Windows Printer via SAMBA. Otherwise, select the protocol your printer uses to communicate.
Insert the details of the network printer and click Forward.
Select the printer model and then click Apply.
Finally, you can enter in a description and location for your printer.


	If you do not know the protocol or details of your network printer, you should consult your network administrator.

Testing a Printer

To check if your printer works correctly:

Choose System → Administration → Printing
Right click on the printer's name in the list.
Click Properties.
Under the Settings tab, Click Print Test Page. A page will then be printed if your printer is working correctly.

How can I check the ink levels of my printer?

To find out how much ink is left in your printer, follow the instructions which apply to your printer:

Hewlett-Packard (HP) printers: Press Alt+F2, type hp-toolbox and click Run. Select the Supplies tab in the HP Device Manager window which appears to view a summary of ink levels.
Epson and some Canon printers: Install the mtink package and click Applications → Accessories → mtink to check your ink levels.
Some other Epson and Canon printers: Install the inkblot package, press Alt+F2, type inkblot and click Run. A printer icon will appear in the notification area on the top panel; click it to view ink levels.

For printers from other manufacturers, the best chance of viewing ink levels for your printer in Ubuntu is to install an official Linux printer driver from your manufacturer if one exists.

This how to is directly pasted from the official ubuntu documentation wiki.
