|
|
|
|
App::Netdisco - An open source web-based network management tool.
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Netdisco is a web-based network management tool designed for network
|
|
administrators. Data is collected into a PostgreSQL database using SNMP.
|
|
|
|
Some of the things you can do with Netdisco:

L<App::Netdisco> provides a web frontend with built-in web server, and a
|
|
backend daemon to handle interactive requests such as changing port or device
|
|
properties.

If you have any trouble getting installed or running, check out the
|
|
L<Deployment|App::Netdisco::Manual::Deployment> and
|
|
L<Troubleshooting|App::Netdisco::Manual::Troubleshooting> notes, or speak to
|
|
someone in the C<#netdisco> IRC channel (on freenode). Before installing or
|
|
upgrading please always review the latest L<Release
|
|
Notes|App::Netdisco::Manual::ReleaseNotes>.
|
|
|
|
=head1 Dependencies
|
|
|
|
Netdisco has several Perl library dependencies which will be automatically
|
|
installed. However it's I<strongly> recommended that you first install
|
|
L<DBD::Pg>, L<SNMP>, and a compiler using your operating system packages.
|
|
|
|
On Ubuntu/Debian:
|
|
|
|
root:~# apt-get install libdbd-pg-perl libsnmp-perl build-essential
|
|
|
|
On Fedora/Red-Hat:
|
|
|
|
root:~# yum install perl-core perl-DBD-Pg net-snmp-perl net-snmp-devel make automake gcc
|
|
|
|
On BSD systems please see L<our BSD tips|App::Netdisco::Manual::BSDInstall>.
|
|
|
|
With those installed, please check that your system's clock is correct.
|
|
|
|
Create a user on your system called C<netdisco> if one does not already exist.
|
|
We'll install Netdisco and its dependencies into this user's home area, which
|
|
will take about 250MB including MIB files.
|
|
|
|
root:~# useradd -m -p x -s /bin/bash netdisco
|
|
|
|
Netdisco uses the PostgreSQL database server. Install PostgreSQL (at least
|
|
version 8.4) and then change to the PostgreSQL superuser (usually
|
|
C<postgres>). Create a new database and PostgreSQL user for the Netdisco
|
|
application:
|
|
|
|
root:~# su - postgres
|
|
|
|
postgres:~$ createuser -DRSP netdisco
|
|
Enter password for new role:
|
|
Enter it again:
|
|
|
|
postgres:~$ createdb -O netdisco netdisco
|
|
|
|
The default PostgreSQL configuration isn't well tuned for modern server
|
|
hardware. We strongly recommend that you use the C<pgtune> Python program to
|
|
auto-tune your C<postgresql.conf> file:

|
=head1 Installation
|
|
|
|
The following is a general guide which works well in most circumstances. It
|
|
assumes you have a user C<netdisco> on your system, that you want to perform
|
|
an on-line installation, and have the application run self-contained from
|
|
within that user's home. There are alternatives: see the
|
|
L<Deployment|App::Netdisco::Manual::Deployment> documentation for further
|
|
details.
|
|
|
|
To avoid muddying your system, use the following script to download and
|
|
install Netdisco and its dependencies into the C<netdisco> user's home area
|
|
(C<~netdisco/perl5>):
|
|
|
|
su - netdisco
|
|
curl -L http://cpanmin.us/ | perl - --notest --local-lib ~/perl5 App::Netdisco
|
|
|
|
Link some of the newly installed apps into a handy location:
|
|
|
|
mkdir ~/bin
|
|
ln -s ~/perl5/bin/{localenv,netdisco-*} ~/bin/
|
|
|
|
Test the installation by running the following command, which should only
|
|
produce a status message (it's just a test - you'll start the daemon properly,
|
|
later on):
|
|
|
|
~/bin/netdisco-daemon status
|
|
|
|
=head1 Configuration
|
|
|
|
Make a directory for your local configuration and copy the configuration
|
|
template from this distribution:
|
|
|
|
mkdir ~/environments
|
|
cp ~/perl5/lib/perl5/auto/share/dist/App-Netdisco/environments/deployment.yml ~/environments
|
|
chmod 600 ~/environments/deployment.yml
|
|
|
|
Edit the file ("C<~/environments/deployment.yml>") and change the database
|
|
connection parameters to match those for your local system (that is, the
|
|
C<name>, C<user> and C<pass>).
|
|
|
|
In the same file uncomment and edit the C<domain_suffix> setting to be
|
|
appropriate for your local site.
|
|
|
|
Change the C<community> string setting if your site has different values, and
|
|
uncomment the C<schedule> setting to enable SNMP data gathering from
|
|
devices (this replaces cron jobs in Netdisco 1).
|
|
|
|
Have a quick read of the other settings to make sure you're happy, then move
|
|
on. See L<Configuration|App::Netdisco::Manual::Configuration> for further
|
|
details.
|
|
|
|
=head1 Bootstrap
|
|
|
|
The database either needs configuring if new, or updating from the current
|
|
release of Netdisco (1.x). You also need vendor MAC address prefixes (OUI
|
|
data) and some MIBs if you want to run the daemon. The following script will
|
|
take care of all this for you:
|
|
|
|
~/bin/netdisco-deploy
|
|
|
|
If this is a new installation of Netdisco 2, answer yes to all questions. If
|
|
you wish to deploy without Internet access, see the
|
|
L<Deployment|App::Netdisco::Manual::Deployment> documentation.
|
|
|
|
=head1 Startup
|
|
|
|
Run the following command to start the web-app server as a backgrounded daemon
|
|
(listening on port 5000):
|
|
|
|
~/bin/netdisco-web start
|
|
|
|
Run the following command to start the job control daemon (port control, etc):
|
|
|
|
~/bin/netdisco-daemon start
|
|
|
|
You should take care not to run this Netdisco daemon and the Netdisco 1.x
|
|
daemon at the same time. Similarly, if you use the device discovery with
|
|
Netdisco 2, disable your system's cron jobs for the Netdisco 1.x poller.
|
|
|
|
For further documentation on deployment, see
|
|
L<Deployment|App::Netdisco::Manual::Deployment>. If you think Netdisco isn't
|
|
behaving correctly, see also the
|
|
L<Troubleshooting|App::Netdisco::Manual::Troubleshooting> page.
|
|
|
|
=head1 Upgrading from 2.x
|
|
|
|
If you're running a version of Netdisco prior to 2.x then you should follow
|
|
the full installation instructions, above. This process is for upgrading
|
|
version 2.x only.
|
|
|
|
Before upgrading please review the latest L<Release
|
|
Notes|App::Netdisco::Manual::ReleaseNotes>. Then, the process is as follows:
|
|
|
|
# upgrade Netdisco
|
|
~/bin/localenv cpanm --notest App::Netdisco
|
|
|
|
# apply database schema updates
|
|
~/bin/netdisco-deploy
|
|
|
|
# restart web service
|
|
~/bin/netdisco-web restart
|
|
|
|
# restart job daemon (if you use it)
|
|
~/bin/netdisco-daemon restart
|
|
|
|
=head1 Tips and Tricks
|
|
|
|
=head2 Searching
|
|
|
|
The main black navigation bar has a search box which is smart enough to work
|
|
out what you're looking for in most cases. For example device names, node IP
|
|
or MAC addreses, VLAN numbers, and so on.
|
|
|
|
=head2 Command-Line Device and Port Actions
|
|
|
|
Most significant Device jobs and Port actions, as well as several
|
|
troubleshooting and housekeeping duties, can be performed at the command-ling
|
|
with the L<netdisco-do> program. For example:
|
|
|
|
~/bin/netdisco-do -D discover -d 192.0.2.1
|
|
|
|
See the L<netdisco-do documentation|netdisco-do> for further details.
|
|
|
|
=head2 Import Topology
|
|
|
|
Netdisco 1.x had support for a topology information file to fill in device
|
|
port relations which could not be discovered. This is now stored in the
|
|
database (and edited in the web interface). To import a legacy topology file,
|
|
run:
|
|
|
|
~/bin/localenv nd-import-topology /path/to/netdisco-topology.txt
|
|
|
|
=head2 Database API
|
|
|
|
Bundled with this distribution is a L<DBIx::Class> layer for the Netdisco
|
|
database. This abstracts away all the SQL into an elegant, re-usable OO
|
|
interface. See the L<Developer|App::Netdisco::Manual::Developing>
|
|
documentation for further information.
|
|
|
|
=head2 Plugins
|
|
|
|
Netdisco includes a Plugin subsystem for customizing the web user interface.
|
|
See L<App::Netdisco::Web::Plugin> for further information.
|
|
|
|
=head2 Developing
|
|
|
|
Lots of information about the architecture of this application is contained
|
|
within the L<Developer|App::Netdisco::Manual::Developing> documentation.
