yum install bind-utils

Or if you do not have access to yum, maybe from a hosted VPS solution you can grab the RPM packages (this is 100% assuming you are CentOS):

rpm -i http://mirror.centos.org/centos/5/os/i386/CentOS/bind-utils-9.3.4-6.P1.el5.i386.rpm

Or maybe you want to install the entire bind/named system:

rpm -i http://mirror.centos.org/centos/5/os/i386/CentOS/bind-9.3.4-6.P1.el5.i386.rpm
rpm -i http://mirror.centos.org/centos/5/os/i386/CentOS/bind-chroot-9.3.4-6.P1.el5.i386.rpm

At my company we do this by running a fax server on an OpenVZ VPS on the same subnet as our Asterisk PBX. Here is how we build our fax server:

First, we build the OpenVZ VPS with CentOS and add the /dev/ptmx device (your VPS will likely already have this on it):

vzctl create 1057 --ostemplate centos-5-i386-default --config vps.basic
vzctl set 1057 --hostname fax.aztecsoftware.net --save
vzctl set 1057 --ipadd 10.0.0.57 --save
vzctl set 1057 --nameserver 10.0.0.15 --save
mknod --mode 666 /vz/private/1057/dev/ptmx c 5 2

(Note: there is a good chance the 98 UNIX device /dev/ptmx is going to already be there from your template — you can disregard any errors you get during the “forced” creation of that device)

Next, we start the VPS and enter the VE by running the following:

vzctl start 1057
vzctl enter 1057

Next, we start the update and install process via yum and a few RPMs I built for Ghostscript:

yum -y update
yum -y install rpm-build make libtiff-devel zlib-devel gcc gcc-c++ pam-devel openldap-devel freeglut libjpeg-devel libICE libSM libXt cairo urw-fonts
 
rpm -Uvh http://chrisschuld.com/centos52/jasper-libs-1.900.1-8.i386.rpm

rpm -Uvh http://chrisschuld.com/centos52/ghostscript-devel-8.63-1.i386.rpm
 
cd /root
wget http://internap.dl.sourceforge.net/sourceforge/hylafax/hylafax-5.2.7-1.src.rpm
wget http://internap.dl.sourceforge.net/sourceforge/hylafax/hylafax.spec
 
rpm -i hylafax-5.2.7-1.src.rpm
rpmbuild -bb hylafax.spec
rpm -i /usr/src/redhat/RPMS/i386/hylafax-5.2.7-1.i386.rpm
chkconfig --levels 345 hylafax on

Now, because we are on Asterisk we’ll use an IAXModem for our communication device; if you do have access to a “real” PSTN by all means use a fax-capable modem and don’t use the IAXModem because it is not a good 100% solution. However, here is our IAXModem method:

cd /root
wget http://voxel.dl.sourceforge.net/sourceforge/iaxmodem/iaxmodem-1.1.1.tar.gz
tar xzvf iaxmodem-1.1.1.tar.gz
cd iaxmodem-1.1.1
./configure
make
cp iaxmodem /usr/local/sbin/
mkdir /etc/iaxmodem /var/log/iaxmodem
touch /var/log/iaxmodem/iaxmodem
pushd .; cd /etc/iaxmodem
wget http://chrisschuld.com/wp-content/uploads/2008/11/ttyIAX0
popd
pushd .; cd /etc/init.d/
wget http://chrisschuld.com/wp-content/uploads/2008/11/iaxmodem
popd
cp config.ttyIAX /var/spool/hylafax/etc/config.ttyIAX0
 
### Add our local configuration differences
vi /etc/iaxmodem/ttyIAX0
 
### Add our local configuration differences
vi /var/spool/hylafax/etc/config.ttyIAX0
 
chmod +x /etc/init.d/iaxmodem
chkconfig --add iaxmodem
/usr/local/sbin/iaxmodem
echo "iax0:2345:respawn:/usr/sbin/faxgetty ttyIAX0" >> /etc/inittab

Now, we REBOOT to make sure everything comes up:

reboot

After the VE re-appears we run our fax setup program:

faxsetup

That should do 90% of the work for you — no you just have to configure the server for your needs!

Today I needed a newer version of ghostscript on my server pool for some back-end processing we do. Updating ghostscript for RHEL5 / CentOS 5.2 turned out to be a pain! I was nearly stucked into RPM hell!

A few google-searches later I realized that ghostscript 8.15 is “old school” and needed a serious update. I always like to have the latest software (generally speaking) so I was after the latest version to date (version 8.63) to hopefully solve some problems with PDF translation:

First, you’ll need the jasper libraries which are not available via yum. You can get them here (i386 32bit only for now):

 
rpm -Uvh http://chrisschuld.com/centos52/jasper-libs-1.900.1-8.i386.rpm
rpm -Uvh http://chrisschuld.com/centos52/jasper-1.900.1-8.i386.rpm

rpm -Uvh http://chrisschuld.com/centos52/jasper-devel-1.900.1-8.i386.rpm

Next, here are the RPMs for RHEL5/CentOS5.2 for Ghostscript (i386 32bit only for now):

 
rpm -Uvh http://chrisschuld.com/centos52/ghostscript-8.63-1.i386.rpm

rpm -Uvh http://chrisschuld.com/centos52/ghostscript-gtk-8.63-1.i386.rpm

*** Problem solved!

PLEASE NOTE: I have posted an update for CentOS5.4 and GhostScript 8.70!

]]> http://chrisschuld.com/2008/11/updating-ghostscript-on-centos-52-ghostscript-863/feed/ 13 Installing PBX in a Flash (PIAF) on an OpenVZ VPS http://chrisschuld.com/2008/11/installing-pbx-in-a-flash-piaf-on-an-openvz-vps/ http://chrisschuld.com/2008/11/installing-pbx-in-a-flash-piaf-on-an-openvz-vps/#comments Fri, 07 Nov 2008 08:28:38 +0000 Chris Schuld http://chrisschuld.com/?p=137 After digging through the Internet looking for a solution to install PBX in a Flash on an OpenVZ VPS and coming out empty handed I decided to dissect the installation myself and I came up with the following method for installing the PBX system on an OpenVZ VPS. Now, that being said I could not find another “working” solution so this may not be the “best” method but it is repeatable and does work. I have a PBX running off this installation currently.

In this example I am going to assume the VPS is VEID 1024 whose IP address will be 10.0.0.24, running on a 10.0.0.0/24 network NAT’ed behind a router with a name server located at 10.0.0.10.

I am also going to assume you have OpenVZ installed, if you don’t visit here: http://www.howtoforge.com/installing-and-using-openvz-on-centos5.2

First, you have to create the OpenVZ VPS container using a CentOS 5 template:

cd /vz/template/cache
wget http://download.openvz.org/template/precreated/contrib/centos-5-i386-default.tar.gz
vzctl create 1024 --ostemplate centos-5-i386-default --config vps.basic
vzctl set 1024 --onboot yes --save
vzctl set 1024 --hostname pbx.mycompany.net --save
vzctl set 1024 --ipadd 10.0.0.24 --save
vzctl set 1024 --nameserver 10.0.0.10 --save
vzctl set 1024 --devices c:4:9:rw --save
vzctl start 1024
vzctl enter 1024

NOTE: you will need access to 13 RPM files from the ISO version of PBX in a Flash so grab the CD so you can get access to the following files:

c-ares-1.3.2-1.i386.rpm
ez-ipupdate-3.0.11b8-3.i386.rpm
flite-1.3-8.fc7.i386.rpm
flite-devel-1.3-8.fc7.i386.rpm
iksemel-1.2-13.i386.rpm
ircd-hybrid-7.2.1-1.i386.rpm
jpackage-utils-1.7.3-1jpp.2.el5.noarch.rpm
lame-3.97-1.fc6.rf.i386.rpm
lha-1.14i-17.i386.rpm
piafdl-0.1-1.noarch.rpm
piafxtras-0.1-1.noarch.rpm
shared-mime-info-0.19-5.el5.i386.rpm
MySQL-shared-compat-5.0.41-0.rhel4.i386.rpm

I looked to find them all online but could not (if anyone knows if they are available please let me know and I will update the site); otherwise I would simply provide the URLs to each file.

Inside of the “fresh” VE I update the root password, copy the RPMs from the CD (see above) and the system using yum:

passwd
mkdir -p /root/piaf/pbx/
#mount the CD here or SCP the files from the CD (or many other options -- but put the 13 RPMs in /root/piaf/pbx/)
scp -r root@SOME_SYSTEM_WITH_CD_MOUNTED:/mnt/cdrom/pbx/* /root/piaf/pbx/
yum -y update

Next, I add all of the packages necessary for PBX in a Flash. This list comes from the ISO CD and the packages that are included across the board for the PBX in a Flash for all cases; I know that it is NOT necessary to have all of these packages; however; I just needed the PBX to work and by adding all of the packages ensures you will have every component for the initial instalation!

Next, I install the other RPM files from the disk:

rpm -Uvh /root/piaf/pbx/c-ares-1.3.2-1.i386.rpm
rpm -Uvh /root/piaf/pbx/ez-ipupdate-3.0.11b8-3.i386.rpm

rpm -Uvh /root/piaf/pbx/MySQL-shared-compat-5.0.41-0.rhel4.i386.rpm

Ok, we are ready to install the PBX software now, finally, run this command:

/usr/local/sbin/piafdl 14

The script will ask you if you would like to use option A (to download the PBX load file from the web site; select that option and the PBX load file will download). The installer will run for a while and will reboot your VPS when the installation is finished.

When the system comes back online add your external IP and local network information into the SIP configuration information in the /etc/asterisk/ folder:

vi /etc/asterisk/sip_general_custom.conf

Add these lines to the file where XXX.XXX.XXX.XXX is your public WAN IP address

externip=XXX.XXX.XXX.XXX
localnet=10.0.0.0/24

Now, restart Asterisk:

/usr/local/sbin/amportal restart

Next, browse to your VPS’s WAN IP address (or URL if you have one) and you should see the FreePBX admin center.
