Synagon is Python-based program that collects and graphs firewall values from Juniper routers. The tool first requires the user to select a router from a list. It will retrieve all the available firewall filters/counters from that router and the user can select any of these to graph. It was developed by DANTE for internal use, but could be made available on request (on a case by case basis), in an entirely unsupported manner. Please contact operations@dante.org.uk for more details.

Installation and Setup procedures
...
Immediately after, a window with a single menu entry will appear. By clicking on the menu, a list of all routers described in the network.py will be given as submenus.

Under each router, a submenu shows the list of firewall filters for that router \(depending whether you have previously collected the list\) together with a 'collect' submenu. The collect submenu initiates the collection of the firewall filters from the router and then updates the list of firewall filters in the submenu where the collect button is located.
The list of firewall filters of each router is also stored on the local disk and next time the tool is invoked it won't be necessary to interrogate the router for receiving the firewall list, but they will be taken instead from the file.
When the firewall filter list is retrieved, a submenu with all counter and policers for each filter will be displayed. A policer is marked with \[p\] and a counter with a \[c\] just after their name. |
When a counter or policer of a firewall filter of a router is selected, the SNMP poling for that entity begins. After a few seconds, a window will appear that plots the requested values.

The tool consists of several files:
Wiki Markup {{felegktis.py}} \[main logic\]Wiki Markup {{graph.py}} \[graph library\]Wiki Markup {{csnmp.py}} \[ SNMP library\]
It is possible by using the squeeze tool (available at http://www.pythonware.com/products/python/squeeze/index.htm\) to make this file into a compressed python executable archive.
...
Compulsory router properties:
Wiki Markup type: the type of the router \[juniper, cisco, etc\] etc \(the tool only operates on 'juniper' routers- address: The address where the router can be contacted at
community: the SNMP community to authenticate on the router
Example:Code Block # Geant network geant = graph.Graph() # Defaults for router class Router(graph.Vertex): """ Common options for geant routers """ def (self): # Initialise base class graph.Vertex.(self) # Set the default properties for these routers self.property['type'] = 'juniper' self.property['community'] = 'commpassword' uk1 = Router() gr1 = Router() geant.vertex['uk1'] = uk1 geant.vertex['gr1'] = gr1 uk1.property['address'] = 'uk1.uk.geant.net' gr1.property['address'] = 'gr1.gr.geant.net'
