netstat-monitor is a commandline tool for monitoring network connections. Its output is similar to the output from the netstat command with the options "netstat --inet -alp". Netstat-monitor can be left running, though, and will report new connections as they are made. Also, filters can be created to limit what's displayed to just what's unexpected or interesting.
Simple Configuration Management provides lightweight configuration management when you don't want to implement a more robust tool like puppet or cfengine. It trades off functionality for simplicity and aims to only provide the bare essential functionality needed to configure a host or its software.
