FAQ

No, no one asked these question yet, but here are the answers anyway :-D

• Why is it called ScavengerEXA ? *

  • As it is a carnivore (http://en.wikipedia.org/wiki/Carnivore_(FBI))
  • which eats your network Junk (http://en.wikipedia.org/wiki/Spam_(electronic))
  • And as it was developed by Exa Networks Limited (http://en.wikipedia.org/wiki/Exa-)

• What are the dependencies for this program *

  • Python, tested with version 2.5.2
  • Twisted Matrix, event-driven networking engine
  • the packet capture library pcap
  • the dump packet module dpkt
  • optional for policy, MySQL with the python MySQLdb modules (http://mysql-python.sourceforge.net/)
  • optional for policy, PosgreSQL with the pg8000 module (http://pybrary.net/pg8000/)
  • optional for action-netfilter, python netfilter
  • optional djb daemontools

• What database can I use for the policy server ? *

  • Do NOT use sqlite3 as production database

  • but it can be used to evaluate the software

  • The policy server uses the Python Database API Specification v2.0

  • so it should trivial to port it to any DB with a DB-API2 interface.

  • sqlite3 and MySQL have been tested, postgresql should just work

  • If you are going to use MySQL you may want to read this article

  • If you are planning on testing postgresql look at this module

• What OS is this designed to run on ? *

  • The main development is done under Linux (both Redhat and Ubuntu)
  • We have no idea if this runs correctly on other Unix flavors.

• What licence is the code released under ? *

  • This code is released under the affero GPL licence v 3.0.
  • Please note that this is the 3.0 only and not any later version (no-one has checked possible license incompatibility issues yet).

• Who holds the copyright for the code ? *

  • Thomas Mangin wrote most of the code whilst working for Exa Networks
  • His collegue David Farrar provided a large amount of help not necessarily correctly expressed in the copyright note added later.

• Can I contribute ? *

  • Sure, send us patches or ideas.
  • We may need you to send a signed copyright transfer, but as no-one has done it yet we have not decided.

• Do your require copyright assignment ? *

  • No, you can keep the copyright of the code you provide as long as you use the project licence.
