fdgw (NetBSD/i386 one floppy system)
fdgw is a single floppy version of NetBSD/i386
(currently tested only on i386 1.5 stable and 1.6 stable).
It is available in the NetBSD package system at
pkgsrc/sysutils/fdgw/
.
This allows you to easily build an fdgw image from
any netbsd-1-5/netbsd-1-6 branch source tree.
fdgw is a minimal operating system. It can
convert an old machine without HDD into a small router
or NAT system. It provides several models:
natbox,
adslrouter,
riprouter(IPv4/v6 RIPv1/v2),
bridge (available only on NetBSD 1.6),
mcastrouter6(IPv6 multicast routing)
and
proxybox(application level gateway) et.al.
The easiest way to get started with fdgw would be to
download a pre-made floppy image which can then be
customized. Images are available from ftp.netbsd.org.
