    Udp2raw-tunnel

    Udp2raw-tunnel

    Turns UDP traffic into encrypted UDP/fakeTCP/ICMP traffic

    A tunnel which turns UDP traffic into encrypted fakeTCP/UDP/ICMP traffic by using Raw Socket, helps you bypass UDP FireWalls(or unstable UDP environment). When used alone, Udp2raw tunnels only UDP traffic. Nevertheless, if you used udp2raw + any UDP-based VPN together, you can tunnel any traffic(include TCP/UDP/ICMP), currently, OpenVPN/L2TP/ShadowVPN and tinyfecVPN are confirmed to be supported. Linux host (including desktop Linux,Android phone/tablet,OpenWRT router,or Raspberry PI) with root account or cap_net_raw capability. ICMP/FakeTCP headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. In ICMP header mode,udp2raw works like an ICMP tunnel. UDP headers are also supported. In UDP header mode, it behaves just like a normal UDP tunnel, and you can just make use of the other features (such as encryption, anti-replay, or connection stalization).

    JRF

    Java Remote File - RemoteInputStream and RemoteOutputStream.

    JRF is a client/server application that allows to extend local storage to other computers running the JRF Server. It has been designed for ultra-simplicity, **not for security!** It does not request for authentication when accessing files on a remote server, nor does it prevent access to files or directories. It has been designed for already-secured networks (e.g. LANs or inside VPNs), where file-sharing setup is tedious (or impossible). Basic access configuration/restriction should be performed on the OS, by changing rights of the user running the JRF Server. It is like an insecure FTP-like file sharing runnning on a single TCP port. Its Java nature gives Java programmers access to remote files as remote `InputStream` and `OutputStream`, with the added value of optionally **compressing data exchange** to ease up network usage.
