Upgrading from request-tracker 3.8.2 to 3.8.3 is a relatively easy procedure.

Become root:
sudo -s

Download request-tracker 3.8.3:
wget http://download.bestpractical.com/pub/rt/release/rt-3.8.3.tar.gz

Untar the archive:
tar zxvf rt-3.8.3.tar.gz
cd rt-3.8.3

Configure:
./configure

Test your dependencies:
make testdeps

All dependencies should be found. If not, you may have to download and install these through CPAN. See this blog post for more information on satisfying request-tracker dependencies.

Perform the upgrade:
make upgrade

When asked what version you are upgrading from, enter 3.8.2

Upgrade the database:
/opt/rt3/sbin/rt-setup-database --dba root --prompt-for-dba-password --action upgrade

Restart apache:
/etc/init.d/apache2 restart

The upgrade process has completed. Browse to your request tracker installation, which will now display 3.8.3 at the logon screen.

I ran into this error when attempting to send local e-mail from my postfix box which sits on the same network as my Microsoft Exchange 2003 server.
554 5.1.0 Sender Denied (in reply to end of DATA command)

The solution to this problem is to disable sender/recipient filtering in Microsoft Exchange.

1. Open Exchange System Manager.
2. Right Click on Message Delivery and select Properties.
3. Browse to the Recipient Filter tab and uncheck Filter recipients who are not in the directory.

Within Exchange System Manager, expand the following:
Servers > "Your Server" > Protocols > SMTP

Right click on Default SMTP Virtual Server and select Properties. Click Advanced within the General tab and then click on (All Unassigned).
Uncheck both Apply Sender Filter and Apply Recipient Filter.

Restart the SMTP service from the command line:
net stop "Simple Mail Transfer Protocol (SMTP)"
net start "Simple Mail Transfer Protocol (SMTP)"

This solution was derived from this website.

Ubuntu configures eth0 with DHCP by default during install.

Changing this has been covered extensively – I’m writing this for my own reference:

Become root:
sudo -s

Edit the intefaces files:
pico /etc/networking/interfaces

Change the eth0 entry to reflect the following:
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.4 # Desired IP Address
netmask 255.255.255.0 # Subnet Mask
broadcast 192.168.0.255 # Broadcast Address
network 192.168.0.0 # Network Address Space
gateway 192.168.0.1 # Default Gateway

Restart networking services:
/etc/init.d/networking restart

Check to see that your changes have been made:
ifconfig eth0

Let’s face it – there isn’t alot of helpful documentation out there when it comes to installing request-tracker. Hopefully this guide can answer some questions.

For those of you who don’t know what request-tracker is, it’s a rather extensive open source ticket and request management system.

I’m making the assumption that you do not have apache2, mysql and a few other bits and pieces installed.
If you do, you may need to approach some of the steps differently.

Become root:
sudo -s

Ensure your system is up to date:
apt-get update
apt-get upgrade

Install build-essential and unzip:
apt-get install build-essential unzip

Update cpan configuration:
cpan
o conf init
o conf prerequisites_policy follow
o conf commit
exit

Install apache2/libapache2/mysql/postfix (if you haven’t already):
apt-get install apache2 libapache2-mod-perl2 mysql-server postfix

Download request-tracker 3.8.2:
wget http://download.bestpractical.com/pub/rt/release/rt-3.8.2.tar.gz

Untar the archive:
tar zxvf rt-3.8.2.tar.gz
cd rt-3.8.2

Configure:
./configure

Check if you have the required dependencies (chances are you need to install them):
make testdeps

If you are warned that you have missing dependencies, escape and perform the following. Otherwise, skip to make install (below).

Install YAML:
perl -MCPAN -e 'install +YAML'

Download and install the required dependencies (select yes at all prompts):
make fixdeps

You might find a dependency or two may fail, try (select yes at all prompts):
RT_FIX_DEPS_CMD='/usr/bin/perl -MCPAN -e"install %s"'
perl -MCPAN -e 'install Bundle::LWP'
make fixdeps

Now let’s make sure that all the dependencies have been installed:
make testdeps

If successful, we should be prompted with:
All dependencies have been found.

We can now install request-tracker 3.8.2:
make install

This will install request-tracker to /opt/rt3

Create a copy of request-tracker’s main configuration file (incase things go wrong):
cp /opt/rt3/etc/RT_SiteConfig.pm /opt/rt3/etc/RT_SiteConfig.pm.old

Open RT_SiteConfig.pm for editing:
pico /opt/rt3/etc/RT_SiteConfig.pm

Replace the contents of the existing file with the following:

# RT_SiteConfig.pm
#
# These are the bits you absolutely *must* edit.
#
# To find out how, please read
# /usr/share/doc/request-tracker3.6/NOTES.Debian


# THE BASICS:

Set($rtname, 'support.example.org');
Set($Organization, 'example.org');
Set($CorrespondAddress , 'support@example.org');
Set($CommentAddress , 'support-comment@example.org');

Set($Timezone , ‘GMT’); # obviously choose what suits you

# THE DATABASE:


Set($DatabaseType, 'mysql'); # e.g. Pg or mysql

# These are the settings we used above when creating the RT database,
# you MUST set these to what you chose in the section above.

Set($DatabaseUser , 'rtuser');
Set($DatabasePassword , 'wibble');
Set($DatabaseName , 'rt3'); # Ensure this is set to rt3!

# THE WEBSERVER:

Set($WebPath , "/rt");
Set($WebBaseURL , "http://host.example.org");
1;

Administer mysql as root:
mysql -u root -p

Create the rt3 database and grant the appropriate permissions:
GRANT ALL PRIVILEGES ON rt3.* TO 'rtuser'@'localhost' IDENTIFIED BY 'wibble'; FLUSH PRIVILEGES;

Exit mysql administration:
exit

Populate the rt3 database:
make initialize-database

Make a copy of httpd.conf:
cp /etc/apache2/httpd.conf /etc/apache2/httpd.conf.old

Edit httpd.conf:
pico /etc/apache2/httpd.conf

Replace the contents of this file with the following:

<VirtualHost *:80>
ServerName www.example.com
ServerAdmin Email.Address@example.com

# config for your main content
DocumentRoot /var/www
<Directory /var/www>
# here and in other places goes config
# of your main host
</Directory>
# as RT is out of document root then we want alias
# and should define directory access

Alias /rt/ /opt/rt3/share/html/
<Directory /opt/rt3/share/html/>
Order allow,deny
Allow from all
</Directory>

PerlRequire /opt/rt3/bin/webmux.pl
<Location /rt/>
AddDefaultCharset UTF-8
SetHandler perl-script
PerlHandler RT::Mason
</Location>
</VirtualHost>

Restart apache2:
/etc/init.d/apache2 restart

Browse to:
http://yourbox/rt/

Update:
The default username and password for the request-tracker portal is root/password.

Bingo!

I understand that request-tracker has the ability to amend incoming e-mail to a specific request queue, however, I am having difficulty getting postfix to play nice with my Exchange server.

This guide will be updated when I figure it out!
