--------------------------------------------------------------------------------

Name        : proxychains-ng
Product     : Fedora 42
Version     : 4.17
Release     : 8.fc42
URL         : https://github.com/rofl0r/proxychains-ng
Summary     : Redirect connections through proxy servers
Description :
ProxyChains NG is based on ProxyChains.

ProxyChains NG hooks network-related (TCP only) libc functions in dynamically
linked programs via a preloaded DSO (dynamic shared object) and redirects the
connections through one or more SOCKS4a/5 or HTTP proxies.

Since Proxy Chains NG relies on the dynamic linker, statically linked binaries
are not supported.
