I'm new to networking (did a little Open Transport many years back), and would like to create a simple app--a diagnostic that finds all the nodes on my local network, plus some remote (such as www.apple.com and www.google.com). The app would then "ping" those addresses on command--just a quick way to verify whether I've lost my DSL connection or something internal to my network. I found the "simplePing" program that works to ping hosts (and figures out what the IP address is of "www.apple.com"). However, I wasn't sure how to figure out the local network addresses. I wasn't sure if Bonjour was the way to go. Any ideas? I'd also like some pointers on where to look to learn more about Mac (or general) networking--I'm not sure where a starting point is. I know I need to understand better sockets, but I'm sure there's more :) I picked my "network" ping app more because I could find it useful (maybe there already is something like that?) but more importantly, I thought it would be a good introduction into networking… This email sent to site_archiver@lists.apple.com
