Changed format of email sent to user on errors.  The error will now
appear instead of the generic message when I am confident it is
accurate.  The subject line will also change to reflect the cause of
an error.

Avoid sending mail to testbed-ops during failed swap related evenets
in some cases.  It will instead be sent to a new mailing list
testbed-errors.

Added a new row in the experiment info table "Last Error:" which
states the cause of the error, and links to a new page displaying the
error.

Made some assign/assign_wrapper errors more informative.

The error (as determined by tblog) is now stored in the database in a
more structured fashion.  This inlcudes adding a column for the session
(in the log table) to testbed_stats to link eash swap event with the
logs and possible the error.

Other changes to the database, see sql/database-migrate.txt

up a tcpdump on both the inside and outside interfaces on the firewall
at boot time.  Another useful form of debugging.

Note: as with the "accept" and "deny" styles of logging, "tcpdump" cannot
be set through any interface other than setting it in the virt_firewalls
DB table directly.

failed because of an NFS hiccup.  Also added a little activity

side of iperf. The main goal is to use much less memory than
'iperf -s'.

Supports many of the same same command line args, so that it can be
used as a dropin replacement for iperf.

Currently only uses about 40k of memory, regardless of how many
clients are connected.

Seems to behave exactly the same as an iperf server, but more testing
is needed.

Fixed a transient error discovered by Junxing. Rather, I've fixed a bug that could account for it and the error hasn't resurfaced after many runs. The transient symptom was when pcap only captured the first three packets and failed from then on.

All measurement times are now based on packet timestamps rather than gettimeofday(), throughput measurement is much more consistent now, though a more thorough evaluation is still required.

Delay is averaged over a quantum. This is probably not the right thing to do, but it is better than the alternative (latest measurement). I am still discussion with Sneha about what to do here.

layout correctly.

As it currently stands, they cannot be automatically swapped because
a paniced experiment will have a firewall node with its control interface
disabled.

automatically.

Now automatically determines the number of peers in the experiment.

run-monitor-libnetmon.sh automatically generates the IP mapping file
now.

Auto-create /local/logs if it doesn't exist (it doesn't on our
devbox image)

Add two new 'auto' scripts - these are intended to be run as part
of the automatic experiments. They properly wait for the stubs
to start before starting the monitors, etc. They log the outputs
of the stub and monitor to /local/logs, where loghole can pick
them up. They also kill their children if they are killed (to be
used with the program agent)

The auto-* scripts need a little more work in term of properly waiting
for their children to exit.

security-level.

tag snmpit error messages as being hardware errors.

Don't export the snmpitFatal and snmpitWarn functions - these are
really supposed to be internal, and I've tweaked their meaning a
bit. Nothing else calls them.

Pass experiment description through to Planetlab as the slice description
when creating a slice.  Also mention the Planetlab AUP and importance of
providing an accurate slice description in the documentation.  The ez
interface also briefly mentions the importance of the slice description.

Added standalone support for multiple streams. Added a logging infrastructure. Added a trivial application for testing purposes (dumb-client and dumb-server). Added the capability for running the standalone stub with a tcpdump replay. Added support for changing buffer sizes. Added shell files for experiment management, reset.sh which is to reset the dummynet settings between runs and run-iperf.sh which encapsulates a set of options to iperf.
