    File Tunnel

    File Tunnel

    Tunnel TCP connections through a file

    File-Tunnel is a tunneling tool that moves TCP connections through a shared file or file server. It is built around the unusual idea that two systems can exchange network data by reading and writing files that both sides can access. This makes it useful in environments where direct TCP connectivity is blocked but a shared folder, FTP server, S3-compatible storage, Dropbox folder, RDP drive share, or similar file channel is available. The project provides portable executables for Windows,...

    An engine to make Tor network your default gateway

    Nipe is a Perl-based engine whose primary aim is to make the Tor network act as the default gateway for outgoing traffic. In practice, it configures system firewall rules (iptables) and network routing so that almost all IPv4 traffic is redirected through Tor. The tool provides commands such as install, start, stop, restart, and status to manage its behavior. When “start” is issued, it sets up the necessary rules; when “stop” is used, it attempts to remove those rules. Nipe currently...
