I have been running all the different cli API tools for EC2 access at work. It is handy and needed for scripting purposes, but so slow, even the command line completion is slow. For example, doing an ec2-describe-instances was taking 1min and 14 seconds, with the new aws-cli tools it takes 1.87 seconds.. Well worth the hassle.

Denyhosts ignores some whitelisting

I had issues at work with some IPs that fall into an IP wildcard range that was in my denyhots whitelist being blocked by denyhosts. It turns out they were Class B networks and denyhosts wildcard white listing only accepts Class C networks. Although written incorrectly here you undestand what it is saying. The examples do only show Class C networks, but it doesn't explicitly say it ONLY accepts Class C networks, hence why it was hard for me to troubleshoot this issue.
