Netcat as Webserver

Netcat is ...; manpage: netcat

As default OpenWrt installs

• busybox-ash (that is the Busybox-fork of the Debian implementation of the Almquist shell (see → http://www.in-ulm.de/~mascheck/various/ash/#busybox). In case you want to read about it.)
• busybox-nc (= the busybox implementation of netcat) does not support server mode.

You can anytime replace those packages by they original counterparts:

opkg install bash netcat
