ToHost.u

sends packets to Linux via Universal TUN/TAP device.

SYNOPSIS§

ToHost(DEVNAME)

Ports: 1 input, no outputs
Processing: push
Drivers: userlevel

DESCRIPTION§

Hands packets to the ordinary Linux protocol stack. Expects packets with Ethernet headers.

You should probably give Linux IP packets addressed to the local machine (including broadcasts), and a copy of each ARP reply.

ToHost requires an initialized FromHost with the same DEVNAME.

IPv4 packets should have a destination IP address corresponding to DEVNAME, and a routable source address. Otherwise Linux will silently drop the packets.

ELEMENT HANDLERS§

• drops (read-only) — Reports the number of packets ToHost has dropped because they had a null device annotation.
