Autobench is a collection of scripts designed to automate the process of benchmarking a Webserver (or for conducting a comparative test of two different Webservers). Autobench runs httperf a number of times against each host, increasing the number of requested connections per second on each iteration, and extracts the significant data from the httperf output, delivering a CSV or TSV file which can be imported directly into a spreadsheet for analysis, or GNUplotted using the included bench2graph script.
nca (Network Console on Acid) connects a pseudo terminal to the consoles' virtual terminals (/dev/tty0, etc.), allowing a remote user to read and write directly to the console. It is supplied with a version of OpenSSH that is hacked so that one can connect to a Linux server and run nca very early in the boot up sequence (immediately after the root filesystem has been mounted read only). It's the next best thing to a serial console for fixing boot-time problems remotely.
