By the installation of Linux on a Windows installed machine the default loading OS becomes the Linux. If the user want to change the default one we have to edit the boot loader file of linux OS.

The name and disk location of the GRUB configuration file varies from system to system; for example, in Ubuntu, Debian GNU/Linux and openSUSE the file is stored in /boot/grub/menu.lst while Fedora and Gentoo Linux uses /boot/grub/grub.conf. Fedora also provides a symbolic link from /etc/grub.conf to /boot/grub/grub.conf for FHS compatibility reasons and other distros can establish symbolic links to the three locations.

Asterisk on Open Solaris

Category: AsteriskBipin Balakrishnan @ 12:28 pm

As i mentioned in the previous post i installed open Solaris in my laptop and worked on it for some time.My next step was to finding out whether we can install asterisk in Solaris.When i googled out about this and got an article telling the performance of asterisk when running it on the solaris OS, which got to be better than in linux.You can read it out from here .

Downloaded asterisk from the SolarisVoIP.

The installation procedure is as follows.

$ pfexec wget http://www.solarisvoip.com/SVasterisk-rev146-x86-5.11.pkg
 $pkgadd -d SVasterisk-rev146-x86-5.11.pkg  

This will make asterisk got installed in your solaris machine.

There is a slight variation in the configuration file created in Solaris than linux.Some important paths needed are explained below.

Configuration file path: /etc/opt/asterisk/  
Call file creation path: /var/opt/spool/asterisk/outgoing/ 
Sound File path :        /var/opt/asterisk/lib/sounds/
Log messages :                /var/opt/asterisk/log/messages
Modules path : /opt/asterisk/lib/modules/ 

Starting asterisk command:

pfexec /opt/asterisk/usr/sbin/asterisk -vvvvvvgc

I have created some sample dial Plans and it got worked on.Later tried AGI with PHP it also got worked on it. Dont have much idea how much will be efficient when connected to Zap channels with Zap channel drivers.For Sip its working fine.
