Setting up NOCLook
This guide is written for Ubuntu 10.04.
Paths used in this guide is just a suggestion, as long as Python can find the files it needs to import it is all good.
Code Block |
---|
sudo apt-get install git-core python-virtualenv openjdk-6-jdk build-essential postgresql python-psycopg2 libpq-dev python-dev |
Postgresql is optional but you need a SQL database. See Django database documentation for other supported SQL databases.
Make a virtual python environment.
Code Block |
---|
sudo su mkdir /opt/python_environments/ cd /opt/python_environments/ virtualenv --no-site-packages norduni |
Making a virtual environment is also just a suggestion but it makes it easier to keep your system clean.
Install needed python modules.
Code Block |
---|
sudo su source /opt/python_environments/norduni/bin/activate pip install django ipaddr argparse pexpect markdown psycopg2 lucene-querybuilder django-tastypie xlwt south django-activity-stream django-jsonfield |
Here psycopg2 is optional but you need to install the Python database module of your SQL database choice. If you have trouble installing psycopg2.
Get the NORDUni files:
Code Block |
---|
cd /opt/ git clone git://git.nordu.net/norduni.git |
Get the NERDS files:
Code Block |
---|
mkdir /opt/norduni/tools/ cd /opt/norduni/tools/ git clone https://github.com/fredrikt/nerds.git |
Symlink admin media and the virtual python environment to niweb.
Code Block |
---|
cd /opt/norduni/src/niweb/ ln -s /opt/python_environments/norduni env cd static ln -s ../env/lib/python2.6/site-packages/django/contrib/admin/media/ admin |
Set password for database user and create a new database
Code Block |
---|
sudo -u postgres psql postgres \password postgres Write password Write password again Ctrl+D sudo -u postgres createdb norduni |
Change the django settings.
Code Block |
---|
# Django settings for niweb project cd /opt/norduni/src/niweb/ cp generic_settings.py settings.py vi settings.py |
Change at least the following settings.
Code Block |
---|
NIWEB_ROOT = '/opt/norduni/src/niweb/' # Database settings DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'norduni', 'USER': 'postgres', 'PASSWORD': 'secret', 'HOST': 'localhost' } } # Neo4j settings NEO4J_RESOURCE_URI = '/opt/norduni/dependencies/neo4jdb/' |
Neo4j >1.5 embedded with Python bindings
Install JPype and Neo4j-embedded.
Download jpype. (http://sourceforge.net/projects/jpype/files/)
Code Block |
---|
pip install neo4j-embedded export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/ pip install /path/to/JPype-version.zip |
Setting up a local/development NOCLook
Set up the SQL database using the Django project.
Change the following lines in urls.py:
Code Block |
---|
cd /opt/norduni/src/niweb/ |
Code Block |
---|
# Django Generic Login (r'^accounts/login/$', 'django.contrib.auth.views.login'), # Federated login #(r'^accounts/', include('niweb.apps.fedlogin.urls')), |
Code Block |
---|
python manage.py syncdb python manage.py runserver 0.0.0.0:80 |
Now you should be able surf to your machines ip and see the NOCLook app started.
It is time to collect and insert some data.
Deploying NOCLook
Comment out the static media url in /opt/norduni/src/niweb/urls.py.
Code Block | ||
---|---|---|
| ||
# Static serve #(r'^site_media/(?P<path>.*)$', 'django.views.static.serve', # {'document_root': settings.STATIC_DEV_MEDIA}), |
Install nginx, postfix and gunicorn.
Code Block |
---|
sudo apt-get install nginx postfix pip install gunicorn |
Create a gunicorn start file.
Code Block | ||
---|---|---|
| ||
#!/bin/bash set -e export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/ LOGFILE=/var/log/ni/noclook.log LOGDIR=$(dirname $LOGFILE) NUM_WORKERS=1 # user/group to run as USER=user GROUP=group cd /opt/norduni/src/niweb source env/bin/activate test -d $LOGDIR || mkdir -p $LOGDIR exec env/bin/gunicorn_django -w $NUM_WORKERS \ --user=$USER --group=$GROUP --log-level=debug \ --log-file=$LOGFILE 2>>$LOGFILE |
Configure nginx.
Code Block | ||
---|---|---|
| ||
server { listen 80; root /opt/norduni/src/niweb; server_name ni.example.net; access_log /var/log/ni/noclook-access.log; error_log /var/log/ni/noclook-error.log; location /static/ { root /opt/norduni/src/niweb/; autoindex on; access_log off; expires 30d; } location / { proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 10; proxy_read_timeout 10; proxy_pass http://localhost:8000/; } } |
Install supervisord and set up the following start script.
Code Block |
---|
easy_install supervisor echo_supervisord_conf > /etc/supervisord.conf |
Code Block | ||
---|---|---|
| ||
description "supervisord" start on runlevel [2345] stop on runlevel [!2345] respawn exec /usr/local/bin/supervisord --nodaemon --configuration /etc/supervisord.conf |
Add the noclook start script to the supervisor configuration.
Code Block |
---|
[program:noclook] directory = /opt/norduni/src/niweb/ user = user command = /opt/norduni/src/start_noclook.sh stdout_logfile = /var/log/ni/supervisor_logfile.log stderr_logfile = /var/log/ni/supervisor_err_logfile.log |
Collecting and processing network data
To insert data you need to stop any python process that is using the Neo4j database. We hope to get the option to load more database instances in read-only mode in a near future then this could be avoided.
NORDUnet has a GIT repository called nistore and it is cloned to /opt/nistore/.
To start have a look at the NERDS README then clone the NERDS project.
Code Block |
---|
cd /opt/norduni/ mkdir tools cd tools git clone https://github.com/fredrikt/nerds.git |
Juniper Configuration Producer/Consumer
The Juniper configuration producer can load Juniper configuration directly from the router via SSH or Juniper configuration files in XML format from disk.
Code Block | ||
---|---|---|
| ||
[ssh] user = view_account_user password = not_so_secret_password [sources] remote = one.example.org two.example.org three.example.org local = /var/conf/one.xml /var/conf/two.xml /var/conf/three.xml |
Code Block | ||
---|---|---|
| ||
"host": { "juniper_conf": { "bgp_peerings": [ { "as_number": "", "group": "", "description": "", "remote_address": "", "local_address": "", "type": "" }, ], "interfaces": [ { "name": "", "bundle": "", "vlantagging": true/false, "units": [ { "address": [ "", "" ], "description": "", "unit": "", "vlanid": "" } ], "tunnels": [ { "source": "", "destination": "" } ], "description": "" }, ], "name": "" }, "version": 1, "name": "" } |
The JSON files can the be inserted using noclook_juniper_consumer.py.
Change the path at the top of the script to be able to import norduni_client.py.
Edit the template.conf file with the correct path to the Juniper NERDS files.
Code Block |
---|
[data] juniper_conf = /path/to/juniper/json nmap_services = alcatel_isis = noclook = |
Then run:
Code Block |
---|
python noclook_juniper_consumer.py -C template.conf |
Alcatel-Lucent ISIS Producer/Consumer
Using the output from the "show isis database detail" on a Cisco router
connected to the Alcatel-Lucent DCN network, nodes and their neighbors
will be grouped.
To get a more human readable result use the IOS command "clns" to map
the NSAP address to a hostname. eg. clns host hostname NSAP_address.
You can also provide a mapping CSV file. The mandatory columns are
osi_address and name. All following columns will be added to the JSON
output.
Code Block | ||
---|---|---|
| ||
osi_address;name;other1;otherN 47002300000001000100010001002060280DB11D;NU-SHHM-ILA-01;info1;infoN |
Code Block |

"host": { "alcatel_isis": { "data": { "ip_address": "", "link": "", "name": "", "osi_address": "", "ots": "", "type": "" }, "name": "", "neighbours": [ { "metric": "", "name": "" }, ] }, "name": "", "version": 1 } |
The JSON files can be inserted with noclook_alcatel_consumer.py.
Edit the template.conf file with the correct path to the Alcatel ISIS NERDS files.
Change the path at the top of the script to be able to import norduni_client.py.
Code Block |
---|
[data] juniper_conf = nmap_services = alcatel_isis = /path/to/alcatel/json noclook = |
Then run:
Code Block |
---|
python noclook_alcatel_consumer.py -C template.conf |
nmap Producer/Consumer
Using the namp services producer you can scan a network or individual addresses. NORDUnet have a file
with networks that is used with the "-iL networks_file" option added to NERDS_NMAP_OPTIONS in the run.sh file.
You need to install two Perl modules if you don't already have them.
Code Block |
---|
cpan Nmap::Parser cpan JSON |
Then you can scan your localhost with:
Code Block |
---|
cd /opt/norduni/tools/nerds/producers/nmap_services ./run.sh -O . 127.0.0.1 |
You will find the JSON file in /opt/norduni/tools/nerds/producers/nmap_services/producers/json/.
Code Block |
---|
"host" : { "." : { "os" : { "family" : "", "name" : "" } }, "addrs" : [ "127.0.0.1" ], "hostnames" : [ "host.example.org" ], "name" : "host.example.org", "services" : { "ipv4": { "127.0.0.1": { "tcp": { "1025": { "product": "Microsoft Windows RPC", "confidence": "10", "name": "msrpc", "proto": "unknown"}, "1029": { "product": "Microsoft Windows RPC over HTTP", "confidence": "10", "version": "1.0", "name": "ncacn_http", "proto": "unknown"}, } } } }, "version" : 1 } |
The JSON files can be inserted with noclook_nmap_consumer.py.
Edit the template.conf file with the correct path to the nmap services JSON files.
Change the path at the top of the script to be able to import norduni_client.py.
Code Block |
---|
[data] juniper_conf = nmap_services = /path/to/nmap/json alcatel_isis = noclook = |
Then run:
Code Block |
---|
python noclook_nmap_consumer.py -C template.conf |
CSV Site Producer/Consumer
The script produces JSON output in the NERDS format from the provided CSV file.
The csv file needs to start with the name of the node and then the node type.
After those two columns any other node property may follow.
Start your csv file with a line similar to the one below.
name;node_type;node_property1,node_property2;...;node_property15
Code Block | ||
---|---|---|
| ||
name;Host;site_type;address;area;postcode;city;country;floor;room;latitude;longitude;responsible_for;owner_id;telenor_subscription_id;comment |
Code Block | ||
---|---|---|
| ||
{ "host": { "csv_producer": { "address": "", "area": "", "city": "", "comment": "", "country": "", "floor": "", "latitude": "", "longitude": "", "meta_type": "", "name": "", "node_type": "", "owner_id": "", "postcode": "", "responsible_for": "", "room": "", "site_type": "", "telenor_subscription_id": "" }, "name": "", "version": 1 } } |
The consumer script should only be run once as it does not update the sites, only creates new.
The JSON file directory is then inserted in to the database using noclook_site_csv_consumer.py.
Change the path at the top of the script to be able to import norduni_client.py.
Then run:
Code Block |
---|
python noclook_site_csv_consumer.py -D /path/to/site_files/json |
Daily database update
The producers are run with a cron job and the script noclook_consumer.py is used to run the three inserting/updating scripts (noclook_juniper_consumer.py, noclook_alcatel_consumer.py and noclook_nmap_consumer.py).
Change the path at the top of the script to be able to import norduni_client.py.
Code Block |
---|
[data] juniper_conf = /path/to/juniper/json nmap_services = /path/to/nmap/json alcatel_isis = /path/to/alcate/json noclook = #Used for loading backup. |
Then run:
Code Block |
---|
python noclook_consumer.py -C template.conf -I |
Purging the database
The database can be purged from all data using the P switch to the noclook_consumer.py script.
Code Block |
---|
python noclook_consumer.py -C template.conf -P |
