If I use USB networking then desktop must be ON to be able to connect with Zaurus.

If I use WiFi card then all packets goes through my router/WAP.

I don’t have Ethernet card for Zaurus to be able to wake machine from Z.

Closest I’ve gotten is this shell script, but it needs arp or a nc with udp broadcast:

#! /bin/sh

# Usage: wake  []
#
#  can be a host name or a dotted-quad IP address.
# If the  is not given, it is taken from ethers(5).
# For this to work, if you give a host name as first argument, ethers
# has to contain host names (as opposed to IP addresses).
#
# Unless you have it already, you can build your ethers file like this:
#
# nmap -sP -PI 192.168.1.0/24   # prepare ARP cache with a ping-sweep
# arp -a | awk '$5 == "[ether]" { printf("%st%sn", $4, $1); }' 
#        | sort >>/etc/ethers
#
# The 'magic packet' consists of 6 times 0xFF followed by 16 times
# the hardware address of the NIC. This sequence can be encapsulated
# in any kind of packet; I chose UDP to the discard port (9).

if [ $# = 1 ]; then
  ETHER=`awk "/$1/"' { gsub(":", "", $1); print $1; exit; }'/etc/ethers`
  if [ -z $ETHER ]; then
    echo "$0: host $1 is not in /etc/ethers" >&2
    exit 1
  fi
else
  ETHER=$2
fi

ETHER="${ETHER}${ETHER}${ETHER}${ETHER}"                # 4 x MAC
ETHER="FFFFFFFFFFFF${ETHER}${ETHER}${ETHER}${ETHER}"    # Preamble + 16 x MACa

### doesn't work on OZ because nc, arp suck... :(
## probably has syntax errors too, haven't checked on real linux yet.

## Inject into ARP table
arp -s 192.168.0.1 `awk "/$1/"' { gsub(":", "", $1); print $1; exit; }'/etc/ethers`

## netcat to start machine
echo ${ETHER} | nc -b -u -p 7
