The XPA messaging system provides seamless communication between many kinds of Unix programs, including X programs and Tcl/Tk programs. It also provides an easy way for users to communicate with these XPA-enabled programs by executing XPA client commands in the shell or by utilizing such commands in scripts. ... A program becomes an XPA-enabled server by defining named points of public access through which data and commands can be exchanged with other client programs (and users). ...

The NTP standard specifies an extension which provides cryptographic authentication of received NTP packets. ... The specification allows any one of possibly 4 billion keys, numbered with 32-bit key identifiers, to be used to authenticate an association. ... In the case of MD5, the keys are 64 bits (8 bytes). xntpd reads its keys from a file specified using the -k command line option or the keys statement in the configuration file. ... A zero key in NTP format would be specified as 8080808080808080 . ...
