koreth@ssyx.ucsc.edu (Steven Grimm) (03/29/89)
These are patches to aufs.c and afpfork.c, to keep track of application
launching on aufs volumes. They allow the creation of an accounting
logfile (specified with the -A option) which contains server pids, time/
date of launching, and application name. This logfile can be run through
a parser (which I will post to the net shortly) to determine simultaneous
program usage for licensing purposes.
One eventual use will be to determine the number of simultaneous users
who should be allowed to run individual applications, to conform to
licensing agreements. We are working on code to limit simultaneous
invocations of administrator-specified files; those diffs will also
be posted when ready.
Note that these changes were made with Budd's lwsrv accounting patches
already present, so if you haven't applied those, you might have to edit
these before applying them.
Questions, comments, and theories to koreth@ssyx.ucsc.edu.
