Description

There is currently no easy way for users to find and block misbehaving Tor relays. If you are using the Tor Browser and see something funny in one tab (say, SSL MITM), you will first need to figure out which circuit that maps to. Vidalia doesn't make this easy. Once you have the IP address of the relay, you will need to edit the Tor configuration file with the ExcludeNodes option and have Tor reload the config. Vidalia doesn't make this easy either.

There should be an easy way to find and block misbehaving Tor relays, either with Vidalia or arm.

I agree there should be better protections against broken relays, however I don't think client side is the way to go. Any mechanism you add that encourages ExcludeNodes will cause some deviance in their circuit patterns, possibly threatening the user's anonymity. It would also be a messy game of whack-a-mole every tor user would be forced to play to get any benefits...

Maybe a better thing to propose would be a relay scanner, something similar to SoaT but designed to detect flakiness rather than maliciousness. That said, it's never gonna happen unless someone volunteers to write it... ;)

What might be helpful is some way for users to find out which exit node a recent connection was sent through even if the stream for that connection has already been closed. The benefits of providing this information would of course need to be weighed against the risks of Tor remembering anything about exit destinations that have been opened.

What if Vidalia colors/highlights circuits by how recently they were used? That would make it easier to see which circuit it was. And recently closed circuits could fade out over 15 seconds.

Then there needs to be an option in the right click menu for a circuit to copy it to the clipboard as a list of relay identities.
