Netdisco INSTALL -- Instructions for setting up Netdisco application.
Netdisco 0.95
PLEASE check the latest version of this document at http://netdisco.org/install.html in case of bugs.
Developed by team of Open Source authors headed by Eric Miller and Bill Fenner.
Orginally created by Max Baker. See list at the end of README of all the contributors.
Netdisco was created at the University of California, Santa Cruz (UCSC), Networking and Technology Services (NTS) department. UCSC continues to support the development of Netdisco by providing development servers and financial support.
Netdisco is an Open Source project hosted by Source Forge.
Please use the netdisco-users mailing list for all help, problems and comments.
Developers, patches, and ideas are always welcome.

Netdisco is built using lots of fine Open-Source tools:
5.6.1 and newer advised.
5.8.1 on Mandrake 9.x may be a problem (if you get
an out of memory error, you may need to change to
5.6.1 or 5.8.3+).
Listed below
5.1.x and newer advised. Reported working on 5.0.x.
Version 7.4 or higher required. Version 8.x suggested.
Reported working for versions 7.2, 7.3, 7.4, 8.0
1.26 or newer required. 1.31 or newer advised.
1.3.x advised, 2.x supported.
Version to match Apache - 1.29 or higher recommended.
Do not install version 1.99. For apache2 support make sure you have mod_perl 2.02 or later.
Version 2.8 or higher recommended.
See INSTALL below for details on how to retrieve and install each one.
Netdisco was developed on a FreeBSD system but should work on any system that Postgres, Perl, Apache, and Net-SNMP run on.
Linux is a sure bet. Netdisco has been tested with Mandake 9.1 and includes specific notes to install with it. Successful installs have been reported under Redhat, Mandrivia, Gentoo and Debian. A beta RPM is available for Mandrivia.
One user has reported getting Netdisco running on OS X. Solaris has been successful for 8 and 10. See http://www.saintmarys.edu/~dmckeown/netdisco_solaris10.htm.
Windows will take a lot of massaging but should be possible under Cygwin.
This is not a terribly easy install. If you aren't comfortable installing programs from source and using a text editor, get some help. Hopefully this will all be rolled up into an install script by the time Netdisco hits version 1.0.
Get the newest version from http://www.netdisco.org.
tar xvfz netdisco-x.xx_with_mibs.tar.gz
Create a directory for Netdisco
mkdir /usr/local/netdisco
Move files to that dir
mv netdisco-x.xx/* /usr/local/netdisco
If you plan to install to a directory other than /usr/local/netdisco then you must
change a couple files. Otherwise Skip down to Number 2.
Modify the following shell scripts to point to your non-standard netdisco directory:
sql/pg_run
sql/pg_init
sql/pg_back
bin/netdisco_daemon
Set the home option in netdisco.conf.
Change all the appearances of /usr/local/netdisco in netdisco_apache.conf
to match your new directory.
Change all the appearances of /usr/local/netdisco in netdisco_apache_dir.conf
to match your new directory.
Create a user and group named netdisco
Give this user permission to the files:
chown -R netdisco.netdisco /usr/local/netdisco
Once Netdisco is up and running most administration can be done from the Web interface. Whoever will be doing the back-end administration will need to have write access and will need write access on Netdisco's files.
Add the unix account names of administrators that will modify the
source code or use the command line interface interface to the netdisco
group in /etc/group.
Don't forget to logout and login after adding yourself to a group.
Netdisco runs Postgres as its database back-end. mySQL and Oracle ports have been rumored but have not yet surfaced.
First install Postgres from ports:
cd /usr/ports/databases/postgresql81-server
make install
Make sure postgresql is configured to start at system startup time by putting
postgresql_enable="YES"
in /etc/rc.conf.
Next initialize the database:
/usr/local/etc/rc.d/010.pgsql.sh initdb
And start the database server:
/usr/local/etc/rc.d/010.pgsql.sh start
Installing PostgreSQL the easy way:
urpmi postgresql postgresql-devel postgresql-server postgresql-docs
The files you will need to edit below are in /var/lib/pgsql/data.
If you lost / don't have install CDs :
The following line uses an FTP site that has the 9.0 RPMs because I lost the CDs. Check the current mirror list at http://www.mandrakelinux.com/en/ftp.php3 and choose a mirror close to you.
urpmi.addmedia ftpsite ftp://mirror.mcs.anl.gov/pub/Mandrake-old/9.0/i586/Mandrake/RPMS \
with ../base/hdlist.cz
Now you have to add --media ftpsite in each urpmi command like so :
urpmi --media ftpsite postgresql postgresql-devel
Remember this for the Apache setup too.
See http://developer.apple.com/internet/macosx/postgres.html for detailed instructions on installing PostgreSQL with OS X.
There is probably a binary package all ready for you. See your distribution's instructions for more help. Otherwise download and compile the source code from http://www.postgresql.org.
If you are installing Postgres from source you may have to run these two commands in order to install the DBD::Pg Perl module later on :
export POSTGRES_INCLUDE=/usr/local/postgres/include
export POSTGRES_LIB=/usr/local/postgres/lib
You may also have to modify your /etc/ld.so.conf to include your new POSTGRES_LIB directory.
Don't forget to run ldconf afterwards.
Netdisco's settings in PostgreSQL are
Database User : netdisco Database Name : netdisco Database Password : you choose it
Follow these steps to setup Netdisco in PostgreSQL.
If you have just setup Postgres for the first time you may have to change the default permissions in $PG_DATA/pg_hba.conf. $PG_DATA might be in /usr/local/pgsql or in /var/db, depends on your OS. Check the postgres users' homedir files for the location of $PG_DATA.
For installation you must give the database user access to the template1 database.
The following line will give all users who have logon permissions in Unix access
to the template1 database.
local template1 all ident
Next you must give the netdisco database user access to the netdisco database.
The following line will give all database users access to a database that is the same
name as them. This line must be put above all the rest of the uncommented lines in the
pg_hba.conf file to take precedence.
local sameuser all md5
You may have to swap md5 for crypt, for old versions of Postgres.
Upgrade.
Finally if you would like to have root be able to access all databases, try this one :
local all root trust
You must now restart Postgres
Linux : one of these three
/etc/rc.d/init.d/postgresql restart
service postgresql restart
/etc/rc.d/postgresql restart
FreeBSD :
/usr/local/etc/rc.d/*pgsql* restart
If there are problems with this step you will receive an error that mentions something about pg_hba.conf.
Make sure your copy of the database is running.
Next, find out the name of your database user. The default name for
some Linux RPM versions is postgres and for some BSD installations pgsql.
Edit the files pg_init and pg_run to match your database user name in /usr/local/netdisco/sql/pg_init
vi /usr/local/netdisco/sql/pg_init
vi /usr/local/netdisco/sql/pg_run
As root run sql/pg_init to create the database and user for Netdisco.
The password you will be asked for twice is the new password for the database user you are creating. This is the same password you will be putting in netdisco_apache.conf and in netdisco.conf.
cd /usr/local/netdisco/sql
./pg_init
Now as a non-privileged user make sure you can get into the database by running
sql/pg_run. Enter the database user password given above.
cd /usr/local/netdisco/sql
./pg_run
You should see output similar to the below:
Welcome to psql 8.0.6, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit
netdisco=>
Once you are sure the database is setup correctly, create the database
tables with sql/pg_all. Type in the database user password once
when prompted.
cd /usr/local/netdisco/sql
./pg_all
If you have freshly installed Postgresql then the default memory usage NEEDS to be increased for efficiency. See the PostgreSQL documentation for postgresql.conf.
Specifically you really need to up the maximum connections and shared memory settings. After you have Netdisco running on a large installation it would be of great benefit to get a Postgres guru in there to tune things for you. See README for more info about how to speed things up now and again.
See http://www.postgresql.org/docs/current/static/kernel-resources.html for kernel settings related to postgres that you should check.
Make sure that Postgres is set to start automatically.
chkconfig postgresql on
Make sure that the file in /usr/local/etc/rc.d is alright and
you have added
postgresql_enable="YES"
to /etc/rc.conf.
Read the section in README about Database Maintenance... every once in a
while you may have to run a VACUUM and REINDEX by hand if things get too slow.
This appears to be less necessary in postgresql 8.0 and up.
If you have postgres installed in a remote location then all you have
to do is add that host information to the db_Pg line in netdisco.conf.
db_Pg = dbi:Pg:dbname=netdisco;host=HOSTNAME;port=PORT;
On the Postgresql machine, allow your remote front end to contact the backend database. Here is a sample line in pg_hba.conf.
#TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD host netdisco netdisco 101.102.103.104 255.255.255.0 md5
Don't forget to restart Postgres after changing the pg_hba.conf file.
There are three components to set up for SNMP:
Net-SNMP 5 lives at http://net-snmp.sourceforge.net.
See OS-specific notes below.
This used to be called ucd-snmp. However, don't download ucd-snmp; it is too old.
When you run ./configure, make sure you add the switch --with-perl-modules
./configure --with-perl-modules --enable-shared
make
make install
If you already have net-snmp installed, then go to the source directory and
in the perl subdirectory and run perl Makefile.PL
cd /path/to/net-snmp-5.1.x/perl
perl Makefile.PL
make
make install
********************************************************************
DO NOT INSTALL the SNMP:: modules off of CPAN or the NET::SNMP module off of CPAN.
********************************************************************
Reread the above line.
You probably will not have to do this step unless you have installed net-snmp somewhere other than /usr/local/ or have some specific SNMP defaults to change for these tools.
snmpconf
Make sure to set the MIB dir if non-standard or you are not using the MIBS that come with Netdisco.
(Textual mib Parsing -> Specifies directories to be searched for mibs)
Make sure this newly created snmp.conf lives in /usr/local/share/snmp or wherever you put a custom install.
OS Specific Notes :
For BSD install Net SNMP with ports :
cd /usr/ports/net/net-snmp && make install
For a recent version of BSD you should get the Perl modules installed automatically.
For a really old version of BSD, or for weird and multiple Perl installs do it by hand!
cd /usr/ports/net/net-snmp
make
cd work/net-snmp-5
./configure --with-perl-modules
make
make install
If you have installed the Net-SNMP RPM from Redhat or Mandrake it does not include the Perl modules. Uninstall it and install a newer version by hand as below.
rpm -e net-snmp
Same goes for Debian. DO NOT use the apt-get version of Net-SNMP, install by hand (it's easy!).
This Perl module is an integral part of Netdisco. It is available from http://snmp-info.sourceforge.net. It requires that you have net-snmp installed first.
SNMP::Info holds all the device-specific code to retrieve data from network devices via SNMP. A wide variety of devices are supported. You may need to add support for other devices if they do not follow a standard interface. This is not too complex. See SNMP::Info for more details.
You have four different options in installing SNMP::Info
perl -MCPAN -e shell
o conf prerequisites_policy ask
install SNMP::Info
Download newest version from http://snmp-info.sourceforge.net
tar xvfz SNMP-Info-0.x.tar.gz
cd SNMP-Info-0.x
perl Makefile.PL
make install
If you plan to add or change device support in SNMP::Info to customize Netdisco to your devices, you should install SNMP::Info this way.
make snmp
This will create the SNMP/ directory where SNMP::Info will live. Periodically you should re-run
make snmp
To update to the most current CVS version. For BSD or Solaris systems, use gmake instead
of make
cd /usr/ports/net-mgmt/p5-SNMP-Info
make install
MIBs that are required for SNMP::Info are included with Netdisco in the mibs/ directory.
They are also available as a separate download on source forge.
GraphViz is used to create the Network Map.
It lives at http://www.graphviz.org/.
For BSD use ports:
cd /usr/ports/graphics/graphviz && make install
For Redhat and Mandrake systems you will make sure that a lol of
-devel packages are installed. If you see errors about not having a PNG
or JPEG library then install the -devel packages as needed.
urpmi libjpeg62-devel libpng3-devel
If you get some weird error in build about not having intl.la then
make sure you have the gettext packages installed :
urpmi gettext-devel
Get the newest version from http://www.graphviz.org/pub/graphviz. Unarchive and install.
Follow the UNIX Instructions but ...
Make the JPEG and EXPAT libraries first and when making the JPEG library make sure you have
./configure --enabled-shared --enabled-static
It is reported to be in DarwinPorts or you can check out http://www.phil.uu.nl/~js/graphviz/.
Jordi Guijarro reported that the version that comes with Woody is too old. Install a newer version by hand.
Copy a True Type Font file (.ttf) into the Netdisco directory and
change node_font in netdisco.conf to match.
cp /path/to/windows/fonts/lucon.ttf /usr/local/netdisco
You can grab arial.ttf or lucon.ttf out of the c:\windows\fonts directory of any Windows machine.
Review other graph settings in netdisco.conf
Make sure that neato/twopi is in your path, and/or in the crontab path that creates the graphs.
which twopi
which neato
After the Perl Modules step below, make sure the Graphviz Perl module got installed
perldoc GraphViz
NOTE: You can safely ignore all warnings about size too small for label.
Apache2 --
Using recent versions of Mason and mod_perl, netdisco runs fine under Apache2. One reported success uses mod_perl 2.0.2 and Mason 1.32. See configuration details under [7.4.4].
See the following three links in addition to this document :
http://www.oreillynet.com/pub/a/mac/2002/11/05/apache_osx.html http://www.oreillynet.com/pub/a/mac/2002/12/18/apache_modssl.html http://www.oreillynet.com/pub/a/mac/2003/02/07/libapreq_update.html
Mandrake 9.1 comes with Apache2. It also has the option of installing a version of Apache1/mod_perl on a different port and then reverse-proxying it.
mod_ssl with Mandrake to come...
Install Apache1 and Mod_Perl 1 and their development packages :
urpmi apache-devel-1 mod_perl-devel-1 apache-mod_perl-1 mod_perl-common-1
Mandrake 9.1 - Do this for the DB_File Perl module
ln -s /usr/include/db1/* /usr/include
ln -s /usr/lib/libdb1.so.2 /usr/lib/libdb.so
Mandrake and some Redhats come with two copies of Apache installed. The mod_perl server sits on a weird port and is reversed proxied by a normal Apache server.
Mandrake 9.0 uses two Apache1 servers, while Mandrake 9.1 uses an Apache2 server that sits in front of the apache1/mod_perl server.
Configuration files for Mandrake live in /etc/httpd/conf
In the file httpd-perl.conf add the two Include lines:
Include /usr/local/netdisco/netdisco_apache.conf
Include /usr/local/netdisco/netdisco_apache_dir.conf
In the file httpd.conf (httpd2.conf for 9.1) add the final RewriteRule line:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^proxy:.* - [F]
RewriteRule ^(.*\/perl\/.*)$ http://%{HTTP_HOST}:8200$1 [P]
RewriteRule ^(.*\/cgi-perl\/.*)$ http://%{HTTP_HOST}:8200$1 [P]
RewriteRule ^(.*\/netdisco\/.*)$ http://%{HTTP_HOST}:8200$1 [P]
</IfModule>
In the file commonhttpd.conf add the Alias line :
Alias /netdisco /netdisco/
/etc/rc.d/init.d/httpd restart
Install Apache 1.3.x and mod_perl 1.x and mod_ssl
Netdisco is designed to work in a secure (https) or non-secure environment. Due to the security and privacy concerned associated with this data, using a secure server is recommended.
Below is my method if you haven't installed apache and mod_perl before. I statically compile mod_perl, and mod_ssl then leave the rest of the modules as dynamically loadable objects (DSO).
Get Apache from http://httpd.apache.org
Get mod_perl from http://perl.apache.org
Get mod_ssl from http://www.modssl.org
Unarchive all three to the same directory, maybe /usr/local/src
This step makes the framework that mod_ssl and mod_perl need.
cd apache_1.3* ./configure
No need to make it yet.
Mod_SSL gives us a secure server (https) for Netdisco to run under.
The OpenSSL library is a prerequirement for mod_ssl and may or may not already be on your system. If not :
Installing OpenSSL :
cd /usr/ports/devel/mm && make install
cd /usr/ports/security/openssl && make install
Setup mod_ssl :
cd /path/to/mod_ssl_1.x.x
SSL_BASE=SYSTEM \
./configure \
--with-apache=../apache_1.3.x \
--disable_rule=SSL_COMPAT
OpenSSL is installed by default.
You will have to tell the OS to look for the Kerberos libraries used in this version of OpenSSL:
./configure \
--with-apache=../apache_1.3.x \
--disable_rule=SSL_COMPAT
make C_INCLUDE_PATH=/usr/kerberos/include
Thanks to David Martin for this info.
Follow the instructions in the INSTALL that comes with mod_ssl
SSL_BASE=/path/to/openssl-0.9.x \
./configure \
--with-apache=../apache_1.3.x \
--disable_rule=SSL_COMPAT
This step sets up mod_perl for this copy of apache :
cd ../mod_perl-1.x
/usr/local/bin/perl Makefile.PL \
APACHE_SRC=../apache_1.3.x/src \
EVERYTHING=1 \
DO_HTTPD=1 \
USE_APACI=1 \
PREP_HTTPD=1 \
PERL_SECTIONS=1
make
Now we're ready to make the main apache and install all of the above (mod_ssl, mod_perl, and Apache).
cd ../apache_1.3*
./configure \
--prefix=/usr/local/apache \
--enable-module=most \
--enable-shared=max \
--activate-module=src/modules/perl/libperl.a \
--with-perl=/usr/local/bin/perl \
--enable-module=ssl
make
make certificate
make install
cd ../mod_perl* make install
Add the following lines in your httpd.conf.
Your httpd.conf will live in /usr/local/apache/conf if you installed using my method.
Add this line once in the end of httpd.conf not in a VirtualHost section.
Include /usr/local/netdisco/netdisco_apache.conf
If you do not have virtual hosts setup and/or you have a main server, add this line right after the first include :
Include /usr/local/netdisco/netdisco_apache_dir.conf
If you have Virtual Hosts or are setting up a secure server, put the following line in each of them that you want Netdisco turned on for:
If you are not using Virtual Hosts, then add this line under the netdisco_apache.conf line.
Include /usr/local/netdisco/netdisco_apache_dir.conf
Make sure you have this include line for the secure server virtual host *:443 at the bottom of http.conf.
Make sure that something similar to the following LoadModule commands are in your httpd.conf:
LoadModule perl_module libexec/apache2/mod_perl.so
LoadModule apreq_module libexec/apache2/mod_apreq2.so
(Note that these should have been done as part of installing mod_perl and libapreq2, but not all installations do this).
Add the following two lines in your httpd.conf:
PerlModule Apache2::compat
PerlModule Apache2::Request
Set the mason data directory writable to the apache user that does the requests.
Assuming nobody is the user that apache requests run this as root :
chown nobody.netdisco /usr/local/netdisco/mason
The name of the user is listed in httpd.conf under the User directive.
Note: Some Linux distributions such as Redhat 6.x install mod_perl as
a Dynamic Shared Object (DSO). This is known to be unstable, especially
with Mason. Compile mod_perl statically using the method listed
above. If you suspect yours is not compiled in, run httpd -l and see if
mod_perl.c is listed (it should be).
Below is a list of required modules for Netdisco, freely available from CPAN http://www.cpan.org. Many of these modules have prerequisite modules.
Use the CPAN module that comes with Perl to install the modules and their prerequisites automatically:
perl -MCPAN -e shell
o conf prerequisites_policy ask
install Digest::MD5
install Bundle::DBI
install Apache::DBI
install DBD::Pg
install DB_File (for Apache::Session)
install Apache::Session
install Apache::Test (for Apache::Request, you may need to do a 'force install')
install Apache::Request
install HTML::Entities
install HTML::Mason
install MasonX::Request::WithApacheSession
install Graph ( > 0.50 )
install GraphViz ( > 2.02 )
install Compress::Zlib (probably already have this one)
install Net::NBName
Some of these you will probably already have installed. Others you may need to force
with force install ModuleName. Do Not include the comments in (parens)!
If you don't have Perl installed in /usr/bin, you will need to modify
the first lines of netdisco and bin/doc_munge.
Modify netdisco.conf to match your site.
See README for detailed configuration descriptions.
Change settings on lines:
session_user_name
session_password
session_cookie_domain
This is where you control the frequency of data collection done by Netdisco. See section 15 of this document for details.
Change center_network_device to a network device that is well connected to the main
segment by CDP/FDP/SONMP.
This is a user inside the Netdisco database that will be your Web Admin User
/usr/local/netdisco/netdisco -u joebob
Add more users from the web Admin Panel once Netdisco is up and running.
This step is only necessary if you have installed from CVS.
Make sure that the POD2TEXT lines in Makefile point to where your Perl binaries
are installed.
You can do this step if you would like the SNMP documentation available from the web as well.
cd /usr/local/netdisco && gmake doc
Since the config files contain SNMP community strings and database passwords, you must make them only available to the administrators for security.
chgrp netdisco /usr/local/netdisco/*.conf chmod 660 /usr/local/netdisco/*.conf
The Organizationally Unique Identifier (OUI) database allows Netdisco to identify the manufacture of a network card using the first 24 bits of a MAC address.
Run the following command to import the contents of oui.txt into your database.
cd /usr/local/netdisco
netdisco -O
The database of OUIs is needed by Netdisco and is available from the IEEE.
If you have lynx installed you can install the OUI database by:
cd /usr/local/netdisco
gmake oui
(gmake for BSD/Solaris)
Or do this by hand:
1. Download oui.txt from http://standards.ieee.org/regauth/oui/ 2. Run netdisco -O
Now that you have everything setup, (re)start the web-server.
Check Apache's error_log for possible errors.
/usr/local/apache/bin/apachectl start
/etc/rc.d/init.d/httpd restart
/usr/local/etc/rc.d/apache2.sh start
or
/usr/local/etc/rc.d/apache.sh start
Also, double-check that Apache starts on its own at reboot. On BSD, make sure that you've added
apache2_enable="YES"
(or similar) to /etc/rc.conf.
Pick a device that you can access with the command snmpwalk.
Tell Netdisco to discover that device:
cd /usr/local/netdisco
./netdisco -d devicename
Make sure that this step actually works. This is a good metric that you have now installed Netdisco correctly. Add the -D flag to get copious debugging info.
See README for a description of Topology Information.
If your network is CDP/FDP/SONMP aware, pick a device that you consider close to the center of the network and start an auto-discovery from there:
cd /usr/local/netdisco
./netdisco -r myrouter
If your network is not CDP friendly, then see README for how to use the manual topology file netdisco-topology.txt.
You MUST supply Netdisco with a working topology or MAC addresses will show up on uplink ports instead of end ports.
First restart Apache so that netdisco will see the changes that you have made in netdisco.conf. Note that a graceful restart will not re-read the configuration file. A full restart is required.
/usr/local/apache/bin/apachectl restart
Point a browser to /netdisco on the server you have Netdisco installed on. If everything is working you should be able to login with the user name and password you added in Step 10. You should also be able to access the Admin Panel.
http://localhost/netdisco
If you have problems, check the error_log of apache for messages.
tail /usr/local/apache/logs/error_log
Once you're sure Netdisco is setup correctly, modify netdisco.crontab.
vi netdisco.crontab
Change center_network_device to one of your core routers or switches.
You may want to fine-tune these jobs to your network. If jobs run too frequent and overlap, nothing bad will happen, it's just higher load on your network devices and Netdisco server.
Once Netdisco has been running for a day, look at the BackEnd Log in the web
browser and see how long each of the jobs is taking to finish. If there is overlap,
for example if your arpnip is taking over 60 minutes or your macsuck is taking
over 120 minutes, then consider decreasing the frequency of these jobs as to not
cause extra load on your network devices.
Now set the crontab to the netdisco user (as root).
crontab -u netdisco /usr/local/netdisco/netdisco.crontab
The admin deaemon performs administration jobs that are requested from the web front-end. See README for a description of the admin daemon.
/usr/local/netdisco/bin/netdisco_daemon start
The daemon will be respawned daily in the Cron job listed above. This isn't 100% necessary, I just did in case the net-snmp libraries had any memory leaks.
If you would like the daemon to be started upon bootup, then do the following:
This is for Redhat/Mandrake/Fedora. Debian and Gentoo might be a little different.
ln -s /usr/local/netdisco/bin/netdisco_daemon /etc/rc.d/init.d
chkconfig --add netdisco_daemon
chkconfig netdisco_daemon on
Now you should be able to use this command:
service netdisco_daemon {stop,start,restart,status}
ln -s /usr/local/netdisco/bin/netdisco_daemon /usr/local/etc/rc.d/netdisco.sh
Add the following line to your /etc/rc.d/rc.local file :
/usr/local/netdisco/bin/netdisco_daemon start
Now that you have spent ten hours of your life installing this go drink a Beer, you deserve it.
Once you have or have not succeeded, come join the Netdisco User's mailing list at http://netdisco.org and pass on any hints you may have in the INSTALL process.
It's a good place to keep up on new features and releases, and it's the place to ask any questions.
