Change IP address for dannenberg (v3 directory authority), and remove moria2 (obsolete v1, v2 directory authority and v0 hidden service directory authority) from the list. Also fix a memory leak when requesting a hidden service descriptor we've requested before. Fix a potential buffer overflow in lookup_last_hid_serv_request() that could happen on 32-bit platforms with 64-bit time_t. We need to do this because Apple doesn't update its dev-tools headers when it updates its libraries in a security patch. Make Tor work again on the latest OS X: when deciding whether to use strange flags to turn TLS renegotiation on, detect the OpenSSL version at run-time, not compile time. We also automatically discard guards picked using the old algorithm. Now we select guards weighted by currently advertised bandwidth. This imbalance meant that Tor clients were severely limited on throughput (and probably latency too) by the first hop in their circuit. We were selecting our guards uniformly at random, and then weighting which of our guards we'd use uniformly at random. Tor 0.2.1.23 fixes a huge client-side performance bug, makes Tor work again on the latest OS X, and updates the location of a directory authority. This post has been edited by Mr Lonely: Jun 26 2009, 07:17 AM Tor's technology aims to provide Internet users with protection against 'traffic analysis,' a form of network surveillance that threatens personal anonymity and privacy, confidential business activities and relationships, and state security. This makes it hard for recipients, observers, and even the onion routers themselves to figure out who and where you are. Instead of taking a direct route from source to destination, data packets on the Tor network take a random pathway through several servers that cover your tracks so no observer at any single point can tell where the data came from or where it's going. Tor also provides a platform on which software developers can build new applications with built-in anonymity, safety, and privacy features.Ĭommunications are bounced around a distributed network of servers, called onion routers.

Using Tor can help you anonymize Web browsing and publishing, instant messaging, IRC, SSH, and other applications that use the TCP protocol. Tor is a toolset for organizations and people that want to improve their safety and security on the Internet.
