fdmess - Summary

This group is not part of the GNU Project.

This is a small utility to redirect file descriptors of running processes and more generally tweak them. It works by attaching with ptrace to an existing process and forcing it to execute some syscall. This way you can force a process to drop privileges, to redirect a file descriptor to a file or a tcp/ip connection, to connect a descriptor to the descriptor of another running process with a unix socket, or to set a file descriptor equal to the descriptor of another running process (unix file descriptor passing is used). Since the code hooks are architecture-dependent, at the moment only the linux-x86 and linux-x86_64 architectures are supported. Patches for other architectures are welcome.
