KSB26, Kernel Socks Bouncer for 2.6.x, is a Linux 2.6.x-kernel patch that redirects full tcp connections through a socks5 proxy. KSB26 uses a character device to pass socks5 and the target IPs the the Linux kernel. This is obviously quite useful if you want to transparently tunnel certain things through a given proxy to remain anonymous, or if you want to transparently be able to sniff certain network traffic.
