One way is to enable a global `LD_PRELOAD=libtsocks.so` (transparent socks) environment variable where you provide an optionally suid (to allow suid binaries to use it if you want) library that overrides `connect`, etc. and forwards them to your socks proxy. Make sure you get ipv4 and ipv6 support if you care. This is not bullet proof by any means. Any application that doesn't using the C library (e.g. go) will not proxy, but most things will.

There is a shell wrapper `tsocks` that does all that - all you need is to configure the SOCKS server/port in /etc/tsocks.conf and run `tsocks $COMMAND`, and all the TCP connections of `$COMMAND` will be tunneled through the SOCKS proxy.

Combined with ssh's `-D` option, it becomes a powerful ad-hoc VPN tool.
