Rb_sys_fail(socket(2)) - errno == 0

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

You can use Ping from the Ruby standard library.

require ‘ping’
Ping.pingecho “google.com”, ,

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.

I was actually hoping for something that creates a real ICMP packet as I
can’t be certain what ports are open on given workstations on the
network.

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:

It’s a busted socket.so in the one click installer I’m afraid (who, in
turn, get it from the core team).

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

Works fine when I use a version of Ruby built with VC++ 8.

If you build ruby without ‘–with-winsock2’, it will work fine.
My bad. Thanks for the clarification.

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.

Ignore this dupe. Submitting replies via the Google groups interface
is seriously messed up. Lately about a third of my posts never arrive,
another third show up several days later (as this one did), with the
final third actually posting in a timely manner.
