    Advanced Onion Router
    Advanced Onion Router is a portable client for the OR network and is intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

    UCall

    UCall

    Up to 100x Faster FastAPI. JSON-RPC with io_uring, SIMDJSON

    Most modern networking is built either on slow and ambiguous REST APIs or unnecessarily complex gRPC. FastAPI, for example, looks very approachable. We aim to be equally or even simpler to use. It takes over a millisecond to handle a trivial FastAPI call on a recent 8-core CPU. In that time, light could have traveled 300 km through optics to the neighboring city or country, in my case. How does UCall compare to FastAPI and gRPC? How can a tiny pet-project with just a couple thousand lines of code compete with two of the most established networking libraries? UCall stands on the shoulders of Giants.

    Adblock FastOwnTracks Recorder

    Adblock FastOwnTracks Recorder

    Store and access data published by OwnTracks apps

    The OwnTracks Recorder is a lightweight program for storing and accessing location data published via MQTT (or HTTP) by the OwnTracks apps. It is a compiled program which is easy to install and operate even on low-end hardware, and it doesn't require an external database. There are two main components: the Recorder obtains data via MQTT subscribes or HTTP POST, stores the data in plain files and serve it via its built-in REST API, and the ocat command-line utility reads stored data in a variety of formats. We developed the Recorder as a one-stop solution to storing location data published by our OwnTracks apps (iOS and Android) and retrieving this data. Our previous offerings (m2s, o2s/Pista) also work of course, but we believe the Recorder is best suited to most environments.

    ProxyChains-NG

    ProxyChains-NG

    Hooks calls to sockets in dynamically linked programs

    proxychains ng (new generation), a preloader which hooks calls to sockets in dynamically linked programs and redirects it through one or more socks/http proxies. continuation of the unmaintained proxychains project. proxychains is a hook preloader that allows to redirect TCP traffic of existing dynamically linked programs through one or more SOCKS or HTTP proxies. The way it works is basically a HACK; so it is possible that it doesn't work with your program, especially when it's a script, or starts numerous processes like background daemons or uses dlopen() to load "modules" (bug in glibc dynlinker). It should work with simple compiled (C/C++) dynamically linked programs though.
