[tor-talk] Relais only within TOR

[anonymous.coward at posteo.de]

Good day evil people ;-)

I want to help strengthen TOR by using tor as a relais, but only within 
TOR, thus no exit relais.
Currently I start TOR using Vidalia.
The TOR process that is running looks like this:
/usr/bin/tor -f /home/foobar/.vidalia/torrc ControlPort 9051 
__OwningControllerProcess 11696 CookieAuthentication 0

What would the tor command look like when being a relais only within the 
network?

Thanks you very much (for giving us tor)
