Well Gordon I can tell you about this at work tomorrow. But that would mean me hovering over your desk and having to listen to another meeting hosted by Rimmer as I am sure you will have at least 12 tomorrow. But it is worth noting on the bottom of the documentation for Net::Ping there is this link to known bugs Multi-Thread Net::Ping It appears that the author of the module agrees with the Roger here.

Some modules to look at:

• POE::Component::Client::Ping
• Win32::PingICMP
• fping

I will look into them more tomorrow morning as you know I need the same functionality.
