Hello everyone, I've read through the path selection specification document and I am a bit confused about guard selection. It says that (when guard nodes are enabled) "Tor maintains an ordered list of entry nodes as one's chosen guards and stores the list persistently to disk. If a guard node becomes unusable, rather than replacing it, Tor adds new guards to the end of the list. When choosing the first hop of a circuit, Tor chooses at random from among the first 3 (by default) usable guard on the list." How is this list derived? What is it ordered by? How many guards are in this list? Are guards added to the list with probability proportional to their bandwidth, as with other types of node selection? Am I safe in assuming that this is a local list unique to the client? Sorry if these questions are a bit basic or if I missed the answers elsewhere. Thanks for your time! -Kevin -- Kevin Gallagher PhD Candidate, Department of Computer Science New York University Tandon School of Engineering 2 MetroTech Center, 10th Floor Brooklyn, NY 11201 Email: kevin.gallagher@xxxxxxx Key Fingerprint: D02B 25CB 0F7D E276 06C3 BF08 53E4 C50F 8247 4861
