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.
