 ===== Installing dependencies =====
+Make sure you have the //non-free// archive present in your
+''sources.list'':
+<code>
+deb http://ftp.no.debian.org/debian/ lenny main contrib non-free
+deb-src http://ftp.no.debian.org/debian/ lenny main contrib non-free
+deb http://security.debian.org/ lenny/updates main contrib non-free
+deb-src http://security.debian.org/ lenny/updates main contrib non-free
+</code>
 Install NAV's runtime dependencies:
+<code>
+sudo aptitude install perl python sun-java6-jdk apache2-mpm-prefork \
+                      cricket postgresql-8.3 libapache2-mod-python \
+                      libpg-java libsnmp1.4-java python-pysnmp2 logrotate \
+		      python-cheetah python-xmpp python-django \
+		      python-egenix-mxdatetime python-gammu python-ipy \
+                      python-ldap python-psycopg2 python-pyrad \
+		      python-pysnmp-se python-twisted python-twisted-snmp \
+		      python-rrd rrdtool samba-common
+</code>
+Be aware that NAV doesn't run well under the //kaffe// Java VM, which is why you should confirm that Sun's Java JDK is installed (''sun-java6-jdk'') and is the active alternative for the ''java'' and ''javac'' commands:
 <code>
-sudo aptitude install perl python java-virtual-machine apache2-mpm-prefork \
+sudo update-alternatives --config java
-                      cricket php4-gd php4-pgsql postgresql-8.1 tomcat5.5 \
+sudo update-alternatives --config javac
-                      libapache2-mod-php4 libapache2-mod-python libpgjava \
-                      libpg-perl libnetaddr-ip-perl libdbd-pg-perl \
-                      libsnmp1.4-java libsnmp-session-perl python-pysnmp2 \
-                      logrotate python-cheetah python-egenix-mxdatetime \
-                      python-forgethtml python-forgetsql python-gammu \

 ===== Unpacking and building NAV =====
 <code>
-tar xvzf nav-3.3.0_rc1.tar.gz
+tar xvzf nav-3.7.0.tar.gz
-cd nav-3.3.0_rc1
+cd nav-3.7.0

 make
 sudo make install
 </code>
+Note: avoid using -j when calling make. It will break the build, since make tries to run many ant processes with interdependencies at the same time.
 ===== Installing and initializing the database schema =====
-Edit ''/etc/postgresql/8.1/main/pg_hba.conf'', change ''ident sameuser'' into ''md5'' for local users connecting through UNIX sockets (except the postgres user).  The file should look something like this:

 While still in the NAV source code directory, ''cd'' to ''doc/sql''.  The following set of commands assume you have sudo access to run commands as the ''postgres'' system user.  If not, please become the ''postgres'' user in some other way.  The procedure has been adapted from ''doc/sql/README''.
-To create the set of PostgreSQL users and databases:

+===== Fixing Python library path =====
+We do this because we don't install the libraries to the systemwide Python library directories by default.  We do however want them available for use systemwide:
 <code>
-# First, export the password you selected for the database user above:
+sudo bash -c 'cat << EOF >> /etc/python2.5/sitecustomize.py
-export PGPASSWORD=<secretpassword>
-psql -f manage.sql manage nav
-psql -f types.sql manage nav
-psql -f snmpoid.sql manage nav

-Change ''/etc/tomcat5.5/server.xml'', the line that reads ''<Connector port="8180" maxHttpHeaderSize="8192"'': alter ''port="8180"'' to ''port="8080"'', as NAV expects Tomcat to listen to this port.

 Edit ''/usr/local/nav/etc/nav.conf'', set your ''ADMIN_MAIL'' and ''DOMAIN_SUFFIX'' options.
+Also set ''DJANGO_DEBUG=True'' if you want complete error information when stuff goes awry in the web interface.
 Optionally make the nav process control command more available: ''sudo ln -s /usr/local/nav/bin/nav /usr/sbin/nav''
+===== Initialize Cricket configuration =====
+Cricket should already be installed as it is a part of the runtime dependencies.
+Remove ''/etc/cron.d/cricket'' or comment out the active cron job line in the file.
+Create a directory to place the nav cricket-config:
+<code>sudo mkdir /usr/local/nav/etc/cricket-config</code>
+Change owner to navcron:nav
+<code>
+sudo chown navcron:nav /usr/local/nav/etc/cricket-config
+</code>
+Edit the /etc/cricket/cricket-conf.pl and set the configroot variable. At the same time, fix the logging. Cricket defaults to /var/log/cricket as logdir. This directory is created on install, but the owner is cricket. Either create your own logdir and set the correct path ($gLogDir) in /etc/cricket/cricket-conf.pl or change ownership of /var/log/cricket to navcron.
+<code>
+$gConfigRoot = "/usr/local/nav/etc/cricket-config"
+$gLogDir = your/log/dir
+</code>
+Copy /usr/local/nav/doc/cricket/cricket/subtree-sets to /etc/cricket/
+<code>
+cd /etc/cricket
+sudo cp /usr/local/nav/doc/cricket/cricket/subtree-sets .
+</code>
+As navcron, copy recursively /usr/local/nav/doc/cricket/cricket-config/ to your cricket-config
+<code>
+sudo -u navcron cp -r /usr/local/nav/doc/cricket/cricket-config /usr/local/nav/etc/
+</code>
+Create a directory to store Cricket's data files, and give ''navcron'' ownership of that directory.
+<code>
+sudo mkdir /usr/local/nav/var/cricket-data
+sudo chown navcron /usr/local/nav/var/cricket-data
+</code>
+Go to the cricket-config directory and edit the "Defaults" file. Replace the Datadir with the correct path to cricket-data. Don't forget the %auto-target-path%
+<code>
+Target  --default--
+    dataDir         = /usr/local/nav/var/cricket-data/%auto-target-path%
+</code>
+Compile the cricket-config as navcron to create the cricket-database.
+<code>sudo -u navcron cricket-compile</code>
+Run ''mcc.py'' to create config from the database. The first time, remember that the database should contain data before doing this. Also, it's a good idea to start ''ipdevpoll'' and let it run a good couple of minutes before making the cricket-config as it then will have gathered and stored information about devices and interfaces in the database.
+<code>
+cd /usr/local/nav/bin
+sudo -u navcron ./mcc.py
+</code>
+Now, start Cricket:
+<code>
+cd /usr/local/nav/bin
+sudo ./nav start cricket
+</code>
+==== Cricket Web ====
+Create the cricket directory in apache/webroot/
+<code>
+cd /usr/local/nav/apache/webroot
+sudo mkdir cricket
+</code>
+Make a symlink to the cricket cgi-scripts and copy cricket.css from source.
+<code>
+cd /usr/local/nav/apache/webroot/cricket
+sudo ln -s /usr/lib/cgi-bin/cricket/grapher.cgi
+sudo ln -s /usr/lib/cgi-bin/cricket/mini-graph.cgi
+sudo ln -s grapher.cgi index.cgi
+sudo ln -s /usr/share/cricket/images
+sudo cp /usr/local/nav/doc/cricket/public_html/cricket.css .
+</code>
+Create .htaccess-file to make sure mod_python doesn't handle this directory.
+<code>
+sudo bash -c 'echo "SetHandler none" > .htaccess'
+</code>
