Re: Selecting and using a particular Tor IP address

forgive the dumb question, but where do you find the
nodename?  Is this the IP address?

If you are using the .exit "hostname" to force a specific tor exit node, then you use that particular tor node name.

A quick, dirty, but mostly working system is to add port 80 to the
long lived port list; this makes high uptime nodes more likely (almost
certainty). Keep in mind that this isn't perfect; if a circuit is
unused for 10 minutes, or more than an hour old, it will be rotated.

My solution? Since this is very common -- all PhPBBS sites, and some
others -- I just add these as exceptions in my privoxy config, so that
they never go through tor. I'm already signing in to the BBS forum, so
they know who I am. Avoiding Tor tells both my ISP and their ISP about
the communication.

A solution that keeps Tor and these nodes?
Combine both "TrackHostExits" and long lived ports.

LongLivedPorts 80,443,23,21,22,706,1863,5050,5190,5222,5223,6667,8300,8888

That adds port 80 to the default list (Boo! I have to respecify the
whole list just to add one port).

That says to make sure that any connection to that host will use the
same exit node.
Warning #1: If the exit Tor node goes down, Tor won't help you on
this. Hence, you want to use the LongLivedPorts to avoid this. (Yea,
that bit me a lot at first.)
Warning #2: Tor makes a 4 hop circuit, not a 3 hop circuit, for
secondary connections when you use this. I don't know why --
seriously, why first make a normal three hop, and then extend to a
forced exit node, rather than making a short two hop, and then extend
to a forced exit node?
