I've been working on a query app for Battlefield 2142 servers, and the following app always fails on some IPs in Windows: http://pastie.org/537069.txt The IPs it works on, it will always work on; the IPs it fails on, it will always fail on. I've left two sample IPs in the application. The IP that does not work on Windows has not ever worked, but I tried it on OS X and it worked flawlessly there despite both the mac and the windows machines being on the same network. I've tried it on three separate Windows machines (two on the same network, one in a data centre) with Windows Vista Ultimate 64 bit, Windows Vista 32 bit, Windows Server 2003 32 bit. It failed on all three of those Windows systems. Both the mac and the Windows machine are running Ruby 1.8.6. Anyone able to help me understand what might account for the problems in Windows? Thanks for any assistance! -- Posted via http://www.ruby-forum.com/.
