=== AUTONAMING FOR TOR ===
Tor directory authorities may maintain a binding of server identities
(their long term identity key) and nicknames. In their status documents
they may for each router they know tell if this is indeed the owner of
that nickname or not.
(their long term identity key) and nicknames.
This toolset allows automatic maintaining of a binding list of nicknames
to identity keys, implementing Tor proposal 123[1].
The auto-naming scripts have been moved to svn in
projects/tor-naming/auto-naming/trunk/
The rules are simple:
- A router claiming to be Bob becomes named (i.e. added to the binding list)
if there currently does not exist a different binding for that
nickname, the router has been around for a bit (2 weeks), and no other
router has used that nickname in a while (1 month).
- A binding is removed if the server that owns it has not been seen
in a long time (6 months).
=== REQUIREMENTS ===
* ruby, and its postgres DBI interface (Debian packages: ruby, ruby1.8, libdbi-ruby1.8, libdbd-pg-ruby1.8)
* postgres (tested with >= 8.1)
* cron
=== SETUP ===
* copy this tree some place, like into a 'auto-naming' directory in your Tor's
data directory
* create a database and a user, modifying db-config.rb accordingly
* initialize the database by executing the sql statements in create-db.sql
* setup a cronjob that feeds the current consensus to the process-consensus
script regularly.
* once the database is sufficiently populated, maybe a month or so after the
previous step, setup a cronjob to regularly build the binding list using
the build-approved-routers script. You probably want to append a manually
managed list of rejections to that file and give it to tor as its
"approved-routers" file.
The Sample-Makefile and Sample-crontab demonstrate the method used at tor26.
