Proxychains is a UNIX program, that hooks network-related libc functions in dynamically linked programs via a preloaded DLL (dlsym(), LD_PRELOAD) and redirects the connections through SOCKS4a/5 or HTTP proxies. It supports TCP only (no UDP/ICMP etc).

This project, proxychains-ng, is the continuation of the unmaintained proxychains project (known as proxychains package in Debian).
