TFTP Installation with ATFTPD

I use the atftpd tftp server daemon. For the most part, it is an easy package retrieval. However there are some custom security and directory settings. Installation

Install the package:

apt-get install atftpd

Edit /etc/inetd.conf and comment out the line with tftpd.

Restart inetd:

/etc/init.d/inetd.dpkg-new restart

Create a new directory, user, group, and privleges:

mkdir /var/atftpd
cd /var
groupadd atftpd
useradd -d /var/atftpd -g atftpd atftpd
chmod 766 atftpd
chown atftpd.atftpd atftpd

Edit /etc/default/atftpd. Add '--user atftpd.atftpd' and change '/tftpboot' to '/var/atftpd'.

Start the service:

/etc/init.d/atftpd start

Installing Asterisk

It has been a year or two since I last worked with the Opensource PBX solution called Asterisk. Instead, I've been doing stuff with Cisco Callmanger and Voice Gateways for the last while. My support pages are still receiving regular hits with regards to Asterisk Support, so I think I should do more with it. I've got a bunch of scripts laying about that I'd like to resurrect.

So, to start off, I have a new Debian server, I need to install the latest and greatest from version control. Here is what I did.

These get me up to current for latest kernel. Compiling Asterisk requires the kernel headers, so they are included here. I want the call detail records to go to a PostgreSQL database, so I include the libraries as well. As the latest source is in Subversion, I need that package to obtain the installation files.

apt-get install linux-image-2.6.18-4-686
apt-get install linux-headers-2.6.18-4-686
apt-get install libncurses5-dev
apt-get install postgresql-dev
apt-get install subversion

Now I can obtain the source files:

cd /usr/src 
mkdir digium 
cd digium 
svn checkout http://svn.digium.com/svn/asterisk/trunk asterisk
svn checkout http://svn.digium.com/svn/zaptel/trunk zaptel
svn checkout http://svn.digium.com/svn/libpri/trunk libpri

Compile the driver files. A double make install will be required. If you are not using Digium hardware, use the ztdummy module, otherwise use the zaptel module. Once compiled and installed, the zaptel configuration file is found in /etc/zaptel.conf and will need to be updated before using the zaptel module.

cd zaptel
make clean
make install
make install
mddprobe ztdummy
modprobe zaptel

For running with PRI digitial telephone circuits, another library needs to be built:

cd ../libpri
make clean
make install

This last one holds the bulk of the Asterisk build.

cd ../asterisk
./configure \
  --sysconfdir=/etc \
  --localstatedir=/var
make samples

That gets us to a basic installation. My next write up will show some of the configuration file stuff I do.
