Hi Folks,

Hi,

Please don't cross post to multiple lists, it makes it hard for people to follow all the responses. Can I suggest that everyone replies to tor-dev, as it's the list for Tor development, feature, and issue discussion. (The other list you used is for Tor relay operators to discuss relay operation and configuration.)

There have been some technical reports about how to deal with the problem when a botnet uses Tor as its primary C&C channel. In this case, the CPU of some relays is exhausted, causing circuit creation failure.

I am wondering currently how a client reacts when its circuit creation fails? Does the client simply resend another create cell or it will re-select new path instead?
