Download the HTML Tag Library and overwrite the existing one which you’ll find by default in “C:\Program Files\Adobe\Adobe Dreamweaver CS5\configuration\TagLibraries” on x86 systems and in “C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\TagLibraries” on x64 systems.

If you are used to using the Visual Studio Command Prompt to quickly get to CasPol, you may find that some of your projects will not seem to respect your new FullTrust settings. The reason is that, unless you are carefully paying attention, the Visual Studio Command Prompt defaults to adding the .NET Framework 4.0 folder to its path. If your project is still running under .NET Framework 2.0/3.0/3.5, it will require setting CasPol for those versions as well. Just a note, I have also personally had more success with using 1 as a code group instead of 1.2.

To trust a network share for all versions of the .NET Framework, simply call CasPol for each version using the full path as below:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\CasPol -m -ag 1 -url file://YourSharePath\* FullTrust
C:\Windows\Microsoft.NET\Framework\v4.0.30319\CasPol -m -ag 1 -url file://YourSharePath\* FullTrust

Before transmitting integers over the wire, a quick call to IPAddress.HostToNetworkOrder() will change the byte order to the communications standard of significant byte first. Receiving integers also requires a single call to IPAddress.NetworkToHostOrder() to ensure the proper value is understood from the incoming bytes.

Read over the “Sockets Byte-Ordering Primer” article over at codeguru.com and the “Converting & Sending Sockets Data with a Leading Length Value” article over at developer.com for some great in-depth explanations on the matter.

If you are reading this as after having followed the steps in my previous article Installing CentOS 5.5 with Linux Integration Services 2.1 on Hyper-V R2 or if you have not selected the following package groups during your installation of CentOS, make sure you do so now by using the following commands.

Preparations

You will need five different passwords.

PASSWORD1 – Your root password.
PASSWORD2 – Used for the asterisk database user.
PASSWORD3 – Used for the FreePBX administrator.
PASSWORD4 – Used for Flash Operator Panel.
PASSWORD5 – Used for the Asterisk Recording Interface.

Requirements

yum groupinstall "DNS Name Server"
yum groupinstall "Web Server"
yum groupinstall "Mail Server"
yum groupinstall "MySQL Database"
yum groupinstall "Development Tools"

Once you are sure that the needed package groups are installed, you will want to install the prerequisites as follows.

yum install e2fsprogs-devel keyutils-libs-devel krb5-devel libogg libselinux-devel libsepol-devel libxml2-devel libtiff-devel
yum install gmp php-pear php-pear-DB php-gd php-mysql php-pdo kernel-devel ncurses-devel audiofile-devel libogg-devel
yum install openssl-devel mysql-devel zlib-devel perl-DateManip sendmail-cf sox

Make sure you also have wget installed.

yum install wget

Next you will setup named.

echo "options {" >> /var/named/chroot//etc/named.conf
echo " directory \"/var/named\";" >> /var/named/chroot//etc/named.conf
echo " dump-file \"/var/named/data/cache_dump.db\";" >> /var/named/chroot//etc/named.conf
echo " statistics-file \"/var/named/data/named_stats.txt\";" >> /var/named/chroot//etc/named.conf
echo "};" >> /var/named/chroot//etc/named.conf
echo "include \"/etc/rndc.key\";" >> /var/named/chroot//etc/named.conf
cd /var/named/chroot//etc/
chmod 640 named.conf
chgrp named named.conf
ln -s /var/named/chroot//etc/named.conf /etc/named.conf

You will want to adjust the security settings as per your requirements but for the simplicity of this article, we are going to turn off Security-Enhanced Linux and open the firewall fully.

echo "SELINUX=disabled" > /etc/selinux/config
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -F
iptables -X
/etc/init.d/iptables save

LAME is required for Asterisk’s audio related functions. You will want to download LAME to a source directory, compile and then install it.

cd /usr/src
wget http://downloads.sourceforge.net/project/lame/lame/3.98.4/lame-3.98.4.tar.gz?ts=1292626574&use_mirror=cdnetworks-us-1
tar zxvf lame-3.98.4.tar.gz
cd lame-3.98.4
./configure
make
make install

You can optionally remove the source once you have installed LAME.

cd ..
rm -fr lame-3.98.4
rm lame-3.98.4.tar.gz

Before continuing, insure that all packages are up to date and then reboot.

yum update
reboot

Installing Asterisk 1.8

Get Asterisk 1.8 and extract it to its own source folder.

cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-1.8-current.tar.gz
tar xvfz asterisk-1.8-current.tar.gz
cd asterisk-1.8.0
contrib/scripts/get_mp3_source.sh
./configure
make menuconfig

The last command will launch the source configuration manager. The only portions you will want to install are app_mysql, app_saycountpl, cdr_mysql, format_mp3, res_config_mysql and EXTRAS-SOUNDS-EN-GSM (which can be found in the Extra Sound Packages sub-menu). Save your selections and exit. Now compile the source and install.

make
make install

You can optionally remove the source directory once you have installed Asterisk.

cd ..
rm -fR asterisk-1.8.0
rm asterisk-1.8-current.tar.gz

Installing FreePBX 2.8

Get FreePBX 2.8 and extract it to its own source folder.

cd /usr/src
wget http://mirror.freepbx.org/freepbx-2.8.0.tar.gz
tar xvfz freepbx-2.8.0.tar.gz
cd freepbx-2.8.0

Start MySQL, create the asterisk databases and run the initial SQL setup scripts.

/etc/init.d/mysqld start
chkconfig mysqld on
mysqladmin create asterisk
mysqladmin create asteriskcdrdb
mysql asterisk < SQL/newinstall.sql
mysql asteriskcdrdb < SQL/cdr_mysql_table.sql

Start the MySQL command line.

mysql

Define the user and password for each of the databases.

GRANT ALL PRIVILEGES ON asteriskcdrdb.* TO asteriskuser@localhost IDENTIFIED BY 'PASSWORD2';
GRANT ALL PRIVILEGES ON asterisk.* TO asteriskuser@localhost IDENTIFIED BY 'PASSWORD2';
flush privileges;
\q

Change the MySQL user to root.

mysqladmin -u root password 'PASSWORD1'

Create the Asterisk user and set folder permissions.

useradd -c "Asterisk PBX" -d /var/lib/asterisk asterisk
chown -R asterisk:asterisk /var/run/asterisk
chown -R asterisk:asterisk /var/log/asterisk
chown -R asterisk:asterisk /var/lib/php/session/

Update the Apache configuration file.

vi /etc/httpd/conf/httpd.conf

Change User apache and Group apache to User asterisk and Group asterisk.

Change AllowOverride None to AllowOverride All.

Update ServerName to use your server’s FQDN.

Start Apache.

/etc/init.d/httpd start
chkconfig httpd on

Start Asterisk.

./start_asterisk start

Configure FreePBX.

./install_amp --username=asteriskuser --password=PASSWORD2

The next series of prompts will give you default values within square brackets which you can accept by hitting enter. If you wish to change a value, simply type it and hit enter after.

[asteriskuser]

This is the database user you specified earlier.

[PASSWORD2]

This is the password for the database user.

[localhost]

Use the default value.

[admin]

The username for the FreePBX administrator.

[amp111]

The password for the FreePBX administrator. It is important to change this. (Use PASSWORD3 you prepared earlier.)

[/var/www/html]

Use the default value.

[xx.xx.xx.xx]

The public IP that will be used.

[passw0rd]

The Flash Operator Panel password. It is important to change this. (Use PASSWORD4 you prepared earlier.)

[extensions]

Use the default value.

[/var/lib/asterisk/bin]

Use the default value.

[/usr/local/sbin]

Use the default value.

Change the Asterisk Recording Interface password and turn on user authentication for the web interface by editing the amportal.conf file.

vi /etc/amportal.conf

Change the ARI_ADMIN_PASSWORD entry to update the ARI password.

ARI_ADMIN_PASSWORD=PASSWORD5

Change the AUTHTYPE entry to database to enable authentication.

AUTHTYPE=database

Optionally, you can turn off the FOP completely by changing the following settings.

FOPRUN=false
FOPDISABLE=true

Save and exit.

Add FreePBX to the boot process.

echo "/usr/local/sbin/amportal start" >> /etc/rc.local

You can ensure that the administrator user has the proper password in the database by navigating to the Administrators tab, choosing the admin user and clicking on the Update password link. Once your password has been updated, logout by clicking the link at the top right of the page.

Finally, reboot the server one last time.

reboot

For Windows administrators new to Linux who wish to provide virtualized services to their end-users, my recommendation is to stick to CentOS 5.5. Being a close derivative of Red Hat Enterprise Linux (RHEL), the officially supported distribution by Microsoft, installation of the Integration Components is simplified and stability is matched to what is found when running RHEL.

Requirements

You will need the CentOS 5.5 x64 installation DVD ISO (CentOS-5.5-x86_64-bin-DVD-1of2.iso) which can be found at http://isoredirect.centos.org/centos/5/isos/x86_64/.

You will also need the Linux Integration Services 2.1 ISO (LinuxIC v21.iso) available through the Microsoft Download Center at http://www.microsoft.com/downloads/en/details.aspx?FamilyID=eee39325-898b-4522-9b4c-f4b5b9b64551.

Initial virtual machine Settings

To create the initial virtual machine, you will need to use the Legacy Network Adapter and limit yourself to a single CPU. You will also want to take time to decide how large of a VHD to allocate ahead of time as expanding a Linux partition can be a little complicated. Personally, I find 20GB to be sufficient for small, single purpose Linux virtual machines.

Installing CentOS 5.5

After booting from the CentOS ISO, you are presented with the choice to do a graphical or a text mode installation. To choose the text mode installation (as used here), simply type “linux text” at the boot: prompt and hit enter.

To navigate throughout the next portion of the text mode installation, use the Tab key to navigate between fields and the Space key to select options or hit buttons.

You will be asked if you would like to do a media test. You can safely skip this.

The initial welcome screen to the installation process.

Choose your language as appropriate.

And your keyboard.

You must then partition your VHD for Linux. As you will be starting off with a fresh VHD, you can simply choose “Use free space on selected drives and create default layout.” and continue with OK.

Be sure to hit No to continue as hitting Yes will simply bring you back to the previous screen.

As long as you have properly configured your virtual machine to use the Legacy Network Adapter, you will be presented with the opportunity to have the installation configure it for you.

Check the “Enable IPv4 support” option and hit OK to continue.

Switch to the “Manual address configuration” option and enter your IP address and netmask as appropriate.

Continue on by entering your default gateway (usually your router or your network’s default route). If you have internal DNS servers for your network, enter them here or alternatively, you can use OpenDNS.

The name of your virtual machine is defined here as the hostname.

Select your time zone and continue.

Be sure to choose a secure root password as the root user has complete access to the entire virtual machine and SSH is enabled on first boot.

For a bare minimum installation, uncheck all of the packages, check “Customize software selection” and hit OK.

Uncheck all package groups and continue. Anything you require can later be installed by yum anyway.

Installation will begin once you continue past this screen.

Once installation is complete, you will be required to reboot.

After rebooting, you will be ready to login. At this point, I recommend connecting via SSH in order to copy and paste commands.

Preparing to install the Linux Integration Components

The first thing that must be done is to update all the base packages and upgrade the kernel to the latest version. Simply run a “yum update”, then reboot.

yum update
reboot

You will need to install the required “kernel-devel”, “gcc”, “make” and “perl” packages to compile and install the Linux Integration Components. Also, I suggest installing the VIM text editor.

yum install kernel-devel
yum install gcc
yum install make
yum install perl
yum install vim-enhanced.x86_64

Installing the Linux Integration Components

Attach the Linux Integration Services ISO. Once attached, you will need to mount the cdrom. You must then copy and compile the source in a temporary folder. Finally, you will be able install the Linux Integration Components. “make” will compile the source, then “make install” will install the compiled drivers.

mkdir -p /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
cp -rp /mnt/cdrom /opt/linux_ic
umount /mnt/cdrom
cd /opt/linux_ic
make
make install

The time synchronisation component is not compatible with CentOS, therefore you will need to install “adjtimex”.

yum install adjtimex

You will need to shutdown the virtual machine in order to enable the Synthetic Network Adapter and increase the number of CPUs allocated. To do so, run the shutdown command.

shutdown -h -t 0 0

Change the settings in Hyper-V once the virtual machine has completely shutdown.

Start the virtual machine and log in. You will need to reconfigure the network adapter as “eth0″ will have disapeared and a new adapter, “seth0″, will have taken its place.

The easiest way to do this is to edit the MAC address in the “eth0″ backup file to match the MAC address of the Network Adapter as displayed in the virtual machine settings in Hyper-V, then copy the backup file as “seth0″ and restart the network service. Don’t forget to also update the DEVICE line use “seth0″.

cd /etc/sysconfig/network-scripts/
vi ifcfg-eth0.bak
(edit DEVICE and HWADDR)
(save and exit)
rm -f ifcfg-seth0
mv ifcfg-eth0.bak ifcfg-seth0
service network restart

If all went well, you will find yourself with a bare minimum install of CentOS 5.5 running the latest kernel and version 2.1 of the Linux Integration Services. Fully virtualized and synthetic. You can now enjoy the many benefits of Hyper-V Linux such as the ability to shutdown the virtual machine without the root password.

As you can see, if you want to hit the majority of the market comfortably, you still have to design for 1024 x 768 resolutions. My general rule of thumb for that resolution is a 960 x 560 viewport design. When you account for scrollbars and an explosion of adware toolbars, that is usually what you have left to work with.

An issue with incorrectly saved proxy port information has been corrected.
