OpenSSG is an implementation of the Cisco Service Selection Gateway, which is available on IOS devices with the required feature image. It uses libipq for user-space packet inspection. Traffic flows of unauthenticated users are redirected to a SESM (Subscriber Edge Service Manager), where they are authenticated by whatever means (an HTTP server with a database backend, or a telnet server). Upon authentication, the user is authenticated with a certain IP and this is sent to the SSG server.
decloak is a utility that endeavors to find hidden processes via PID exhaustion. It exploits the linear manner in which PIDs are assigned to new processes to reveal unseen processes. When a process is found, the script checks a few functions such as getpriority, getsid, getpgid, and the contents of /proc/(pid)/cmdline and reports them.
