Isolation level may be funky and share circuits?
I am using tor 2.3.19-rc for windows. The below i quote the Docs.
I have 7 SOCKSPort (SOCKSPort 9050 bc TBB wont allow me to use any other ports, + SOCKSPort 1230-1235) Using vidalia i look at my circuits and i only have 5. With an app i check my IP Address using "https://check.torproject.org/?lang=en-US&small=1&uptodate=1" and throw an error if there are duplicate ipaddresses. I use a simple webrequest using privoxy as my proxy
The result was 3 of the 7 got an ip while the others failed. I tried running repeatedly. I'm not sure i only have 5 circuits but i am only using 3 of them for the 7instance (all using different ports). Later on when i had more circuits i tried. Again only 3 were unique.
Perhaps this is a bug? I pretty much used the default TBB but replaced files from the new tor, removed one line bc it was incompatible with SOCKSPort (port 9050) then add additional 6 SOCKSPort for different ports. I turn on tor the same way i normally do with TBB. I click a shortcut. This is installed on a portable drive.
Don’t share circuits with streams from a different client address. (On by default and strongly recommended; you can disable it with NoIsolateClientAddr.)
