Brute Force protection for CopSSH Server

We've used the CopSSH package to provide SSH and SFTP service on various Windows servers. Until now, we have not had a solution in place to block brute force attacks on the SSH server. We use the excellent fail2ban on our Linux systems, but we had not found a similar tool for Windows.

Yesterday we came across a solution to this problem:

It works very well on a Windows Server 2008 system where we've deployed it. The only thing it's lacking is a way to automatically remove banned IPs after a period of time. We'll post an addition to this tool if we implement this feature.

64-bit MySQL, 32-bit Ruby

Happy New Year, everyone!

As is far too often the case these days, we ran into a problem while trying to make 32-bit software play nicely with 64-bit software. One of our OS X 10.5 workstations had 64-bit MySQL installed as well as fink's 32-bit ruby. It took some time to sort out, but we ultimately solved the problem by following these instructions. Thanks to Josh there for the creative (though rather hackish) solution!
