If you think, that you will need the necessary feature to upload large files then there are two ways by which you can enable this feature.

i) Edit the physical file and have the line
ini_set(“memory_limit”,”20M”);

ii) Edit php.ini and add the following line. You need to restart the apache/IIS server once php.ini file is modified.
memory_limit=32M

You can download the free version at http://www.any-video-converter.com/products/for_video_free/

Input formats:
avi, asf, mov, rm, rmvb, flv, mkv, mpg, 3gp, m4v, vob, YouTube videos

Output formats:
avi, mp4, wmv, swf, flv, mkv, MPEG-1 and MPEG-2, mpg (PAL or NTSC), mp3, wma, ogg, aac, wave, m4a

Solutions that seemed to have worked for me

i) Host name: Try adding ftp://www.mysite.com and set the port to 21
ii) User name: Try typing username@domain.com instead of just the user name of the ftp user

Usage: In addition to the different flavors of Linux in the market, comes the usage of Linux. Some variants are developed as Desktops and a major as servers. In addition to that, there are virtual appliances that are packaged with other applications for easy deployment across environments. The choice is many and the usage determines the choice of the Linux flavor in most cases.

Client Support: All distributions are open source – FREE for usage. Red Hat and Ubuntu are maintained by organizations which provide commercial support which bigger organizations prefer. CentOS, Debian, Fedora are maintained by volunteers.

Commands used: For an administrator it will be easy if ALL the systems in the network use the same distribution. Some commands that are used to achieve a functionality are not consistent across distributions.

Packaging: Feature enhancements, application patches, software installation and management differ from one distribution to the other making the need for the administrator to remember the subtle keys.

Manage data tables, export/import databases, synchronise tables between databases, integrity check, database backup service management, edit database content and many more features packaged as a solution for ALL your MySQL needs.

This runs on windows platforms – WinXP/XP7 and you can download HeidiSQL from Download link

Another GUI tool that is available in the market is MySQL Workbench. The OSS edition of this tool is available under GPL and provides database administrators with database design, modeling with an intuitive GUI. Download MySQL Workbench

After saving these two files, start up asterisk.
$ asterisk -vvvvgc

The above command will open the asterisk CLI – Command Line Interface

Asterisk Error: No music on hold classes configured disabling music on hold
> Edit /etc/asterisk/modules.conf and make changes not to include res_musiconhold.c by setting “noload => res_musiconhold”

- Check if asterisk is running
$ /etc/init.d/asterisk restart
$ asterisk -r

Originally developed for Linux, Asterisk now runs on a variety of operating systems including Solaris, Windows and MacOS.

Environment setup


Asterisk server is configured on a HP dx5150 AMD Athlon, 512 MB RAM, 40 GB machine running CentOS.
Softphones used in the tutorial: Zoiper is used for IAX2 communication and X-Lite for SIP. Both the softphones are configured on Windows XP.

Asterisk: Step by Step
1) Download the asterisk software from asterisk.org. We will be going with the base build and not use other softwares like AsteriskNow or PBXinaFlash for the moment.

2) Setup asterisk repo to ease future upgrades to asterisk
$ cd /etc
$ touch asterisk.repo
$ vi asterisk.repo

[asterisk-tested]
name=CentOS-$releasever – Asterisk – Tested
baseurl=http://packages.asterisk.org/centos/$releasever/tested/$basearch/
enabled=0
gpgcheck=0
#gpgkey=http://packages.asterisk.org/RPM-GPG-KEY-Digium

baseurl=http://packages.asterisk.org/centos/$releasever/current/$basearch/
enabled=1
gpgcheck=0
#gpgkey=http://packages.asterisk.org/RPM-GPG-KEY-Digium

3) Install asterisk on CentOS and start up asterisk
$ yum install asterisk16 asterisk16-configs asterisk16-voicemail libpri

[Source: Check asterisk.org]

To enable auto start of asterisk
$ chkconfig asterisk on

Start/stop/restart asterisk using the commands
$ service asterisk start
$ /etc/init.d/asterisk restart
$ service asterisk stop

To test asterisk service type
$ asterisk -r

4) Register with a VOIP Service provider
To search for the VOIP provider you can use
voip-info.org which has an extensive list of service proivders categorized by region based on different
market segmentation.

Once you have registered with a VOIP Service provider, they will give you
IAX2/SIP Account (your phone number) : NNNNNNNNNN
Account password : PPPPPPPP
IAX2/SIP Server name : myiax.voipprovider.org

So far, we have detailed the environment, setup asterisk on a CentOS server and have registered for an account with a VOIP provider. In the next tutorial, we will see how to configure asterisk settings and to setup an IAX extension for a softphone (soft client) running on windows XP.

Possible Scenarios
i) Server load balancing
ii) Moving web sites between servers

Find where the SSL certificates, private keys are installed in the old server and gzip the certs
$ tar -zxcf /tmp/crt.tar.gz /etc/ssl/certs
$ tar -zxcf /tmp/priv.tar.gz /etc/ssl/private

In the new server, extract the certificates and keys to its respective folder location. Edit httpd.conf file and add the following lines

SSLEngine on
SSLCertificateFile /etc/ssl/certs/example.com.crt
SSLCertificateKeyFile /etc/ssl/private/example.com.key
SSLCACertificateFile /etc/ssl/certs/example.com.cabundle
CustomLog /usr/local/apache/domlogs/exampleuser-ssl_log combined

Sample virtual host configuration setting

<VirtualHost xxx.xxx.xxx.xxx:443>
    ServerName subdomain.example.com
    ServerAlias www.subdomain.example.com
    DocumentRoot /home/emaple/public_html
    ScriptAlias /cgi-bin/ /home/example/public_html/cgi-bin/
    SSLEngine on
    SSLCertificateFile /etc/ssl/certs/example.com.crt
    SSLCertificateKeyFile /etc/ssl/private/example.com.key
   SSLCACertificateFile /etc/ssl/certs/example.com.cabundle
  CustomLog /usr/local/apache/domlogs/exampleuser-ssl_log combined
    SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
    <Directory "/home/example.com/public_html/cgi-bin">
        SSLOptions +StdEnvVars
    </Directory>

    # To customize this VirtualHost use an include file at the following location
    # Include "/usr/local/apache/conf/userdata/ssl/2/exampleuser/example.com/*.conf"
</VirtualHost>

Restart apache
$ /etc/init.d/httpd restart
(or)
$ /sbin/service httpd restart

Note: Once moving the SSL certificates to the new server, you can also use WHM or CPanel to configure the certs.
