CCHEF (Covert Channels Evaluation Framework) is a software framework for empirically evaluating covert channels in network protocols running under Linux. CCHEF can be used in real networks with real overt traffic, but can also emulate covert channels using overt traffic from trace files. CCHEF was mainly designed for research purposes, but not to be (mis)used for real covert channel communication. Therefore, the sender/receiver application is a normal user space programs and not disguised in any way.
CVM (Credential Validation Module) is a modular system for validating credentials and providing information about them, using either piped command execution, Unix sockets, or UDP as the data transport. It is designed to be simpler than other existing systems (like PAM and Courier's authentication modules) and yet adequately functional for the majority of tasks.
