ttdnsd accepts DNS requests via UDP and forwards the to a resolving
|
|
nameserver via TCP. The actual requests are really just forwarded so
|
|
one has complete access to the nameserver ttdnsd is talking to.
|
|
|
|
It's not a very complicated process. If there are no problems with the
|
|
setup it could go as smoothly as connecting to the 'net using a mobile
|
|
broadband dongle.
|
|
|
|
ttdnsd only connects to the resolving nameserver after receiving
|
|
a request via UDP. For each connection ttdnsd randomly selects one
|
|
of the nameservers it knows about. The connection will be used for
|
|
forwarding multiple requests in a pipelined fashion and is kept open
|
|
only until no more requests are received via UDP. This pipelining is
|
|
required to overcome the initial connection overhead time which is
|
|
quite long when using Tor.
|
|
|
|
To run this service at system startup, edit your rc.local and add this
|
|
code:
|
|
|
|
if [ -x /etc/rc.d/rc.ttdsnd ]; then
|
|
/etc/rc.d/rc.ttdsnd start
|
|
fi
|
|
|
|
...after the similar code used to start the Tor service. To stop the
|
|
service add this to your rc.local_shutdown:
|
|
|
|
if [ -x /etc/rc.d/rc.ttdsnd ]; then
|
|
/etc/rc.d/rc.ttdsnd stop
|
|
fi
|
|
|
|
...before the Tor shutdown routines. Remember that this package acts
|
|
like a DNS resolver so it listens by default on port 53. If you're
|
|
going to run another DNS server like bind either as a cache to this
|
|
server or in parallel, remember to modify ttdnsd default port or it
|
|
will not start.
