The command-line tools included with FlowTraq can establish a persistent session with FlowTraq Server based on pre-authenticated session keys issued by FlowTraq Server. When using any command-line tool to login to FlowTraq Server (using the standard -un -up username/password authentication method) a request can be made for a re-authentication session key, using the -us argument:
fthostsb -un USERNAME -up PASSWORD -us
A session key will be provided as part of the tool's output, and the key subsequently used with the -us argument instead of instead of a username/password combination to re-login to the same FlowTraq Server from the same IP address:
fthostsb -us SESSIONKEY

The session key re-authentication interface creates an easy way to integrate FlowTraq into existing third-party applications using the suite of command-line tools. For instance, the use of session keys allows a scripted web GUI to re-authenticate without storing the username and password in a client-side cookie. Since the session key automatically expires, and is only valid from the originating IP address, it is unnecessary to perform an explicit "log out."
