sorted view, much like the public listing, with a section for active
and a section for inactive. The alternate view is accessed via a link
at the top of the page that allows you to switch between them.

pages now show the lastlogin info that is gathered from sshd syslog
reporting to users. That info is parsed by security/genlastlog.c, and
entered into the DB in the nodeuidlastlogin and uidnodelastlogin
tables. If not obvious from the names, for each user we want the last time
they logged in anyplace, and for each node we want the last time anyone
logged into it. The latter is obviously more useful for scheduling
purposes. All of the various images have new /etc/syslog.conf files,
and the 6.2 got new sshd_configs (all cvsup'ed with kill -HUP). There
is an entry in boss:/etc/crontab and users:/etc/syslog.conf. All of
this is decribed in greater detail in security/genlastlog.c.

but simply entered into the DB record for the experiment until we know
what to do with them. Add to batchexp script arguments, since all that
stuff is done outside the web interface. Add a swapexp perl script to
swap an an experiment in/out form the command line. Add web links on
the Experiment Information page to do this from the web interface. A
bunch of locking changes. Previously expt_terminating in the
experiment record prevented multiple calls to terminate an experiment,
but now we have a more general locking problem with
start,swapin,swapout, and terminate, so change expt_terminating to
expt_locked (still a datetime field) and add locking to all of
startexp, swapexp, and endexp. Note that batch experiments cannot be
swapped yet because of locking issues still to be resolved. Minor
cleanup in tbreport to make email message look better.

experiment code. No longer uses another table. Rather, the experiment
record contains a couple of extra fields for the batch system. Also
combined some of the backend code (no longer a killbatch script).
Also added scriptable experiments; the batchexp program in the bin
directory can start an experiment from the command line, and in fact
is used from the web page for both batch experiments and immediate
experiments (-i option). All of the DB code that was in the web
interfaces was moved to batchexp.

replaced by the "images" table. New os_info table is added. New web
pages to add and delete OSIDs to/from the os_info table, for use in
the NS file. tb-create-os is gone. handle_os no longer operates on the
tbcmds file, and no longer writes anything into the ir file. Moved the
setting up of os state (nodes table) from os_setup to handle_os, where
it should be. os_load and sched_reload now take a single argument, the
name of the imageid from the images table.

of all that duplicated goo).
Clean up all the formerror code, calling standard FORMERROR() function.
Get rid of all the inline DB specific constants, moving them to dbdefs.php3
include file.
