Operating Systems Solaris WakeOnLan, tcp packet Post 302918966 by Corona688 on Friday 26th of September 2014 12:14:47 PM

You can't telnet to a machine that's asleep. Incidental traffic to a "wrong" machine won't work either, a modern switched network won't repeat it to anything else. Only broadcasts go to everyone.

So it pretty much has to be a connectionless broadcast -- UDP or ICMP. But ping won't let you shoehorn in the magic sequence, so that's out.

How about a perl script?

varnetload(8)					    Tool to create reproducable network traffic 				     varnetload(8)

NAME
varnetload - tool to create reproducable network traffic SYNOPSIS
varnetload [-d delay] [-t time to run] [-u url] DESCRIPTION
varnetload is a simple python script to create reproducable sustained network traffic. In order to use it effectively, you need to have an HTTP server present in your local LAN where you can put files. Upload a large HTML (or any other kind of file) to the HTTP server. Use the -u option of the script to point to that URL. Play with the delay option to vary the load put on your network. delay Sets delay between individual downloads in miliseconds. Default value is 1000. But you my find values range from 0 to 500 more use- ful. time to run Sets total run time in seconds. Default value is 60. url Sets downloaded resource. Default is http://myhost.mydomain/index.html. SEE ALSO
