dnscrypt-proxy acts as a DNS proxy between a regular client, like a DNS cache or an operating system stub resolver, and a DNSCrypt-aware resolver, like OpenDNS. The DNSCrypt protocol focuses on securing communications between a client and its first-level resolver. While not providing end-to-end security, it protects the local network (which is often the weakest link in the chain) against man-in-the-middle attacks. It also provides some confidentiality to DNS queries.
UDP IPTV to RTSP proxy is a lightweight GNU/Linux daemon which, being installed on a LAN router, provides on-demand access to UDP multicast streams via RTSP, RTP, and HTTP unicast protocols. The server itself does not support streaming of any files, it only can receive incoming multicast streams provided by your ISP and retransmit them to interested local clients. The main purpose of the software is to provide simple IPTV service to small office or home ethernet and/or Wi-Fi LANs where upgrading the network to handle multicast correctly is not an option. It is not intended to handle large-scale installations and service clients you don't trust (like the public Internet).
