You can use Ping from the Ruby standard library.

require 'ping'
Ping.pingecho "google.com", <timeout>, <port>

Where timeout is the number of seconds to wait for a reply (defaults
to
5) and port is the port to use (defaults to the 'echo' port)

Unless you have something more specific you are trying to do this
ought
to work.

That is the error message I get when I try either of these methods
for
creating an ICMP packet:

socket = Socket.new(Socket::PF_INET, Socket::SOCK_RAW,
Socket::IPPROTO_ICMP)

or

with net-ping

icmp = Ping::ICMP.new('machine_name')

icmp.ping?

I am on Windows XP. The account I'm logged in as has local
administrator
rights.

What I'm trying to do is check to see if a system is up before I try
and
make a WIN32OLE connection to it as they take forever to time-out

It's a problem with the socket.so file that ships with the one click
installer. Take a look at this ticket for more information:


http://rubyforge.org/tracker/?func=detail&group_id=167&aid=9438&atid=715

The socket.so has nothing to do with this problem.
It's a problem with the msvcrt-ruby18.dll file.

That bug is related to the winsock2 compatibility.

The OCI version was built with the flag '--with-winsock2'.
If you build ruby without '--with-winsock2', it will work fine.

My bad. Thanks for the clarification.
