Set mailgap to 15 seconds, and wait a second on startup before sending mail so that the timeouts all come in one message. And don't clean up my stated.pid file if I'm a forked child of the real daemon.

Also made the image and osid shared so that it works for any emulab user
who swaps in an experiment. Before this, swapping an nse expt would have
failed but since no uses it, we never had any problem!

mention tipserv1 as well as ops for setting up serial lines

bytes of framing+CRC

Add pcapper.noevents target to Makefile to build without event system

set the login shell to /sbin/login. Minor complications for preserving
the existing shell of users on both boss/ops, but no big deal.

Dave and RON node installation.

library.
Add -b option to explicitly turn on broadcast mode (client and
server), and fiddle with options and network init slightly so that
I can do simple unicast experiments between two nodes.

the osdi paper. doc.php3 now links to tutorital/tutorial.html#Advanced
instead of tutorial/advanced.html for the "Advanced Tutorial". The latter
is anyway linked from the former.

simulated nodes.

changes; add optinal jailflag argument to TBIsNodeVirtual, and add some
constants for assigning port ranges to jailed nodes.

newwanode: Allow reuse of existing node. So, if called with an IP that
already exists in the DB, reuse those records (nodes, interfaces,
reserved) rather than creating a new one. The web page makes sure that
the calling node has a valid IP (REMOTE_ADDR equals IP it gives us),
so it typically means an exiting node is being reinstalled (happening
with RON nodes right now!).

now it is just hardcoded to 4, but could be done from the db too. Gives
errors like this one, from a topo where node2 and node6 each have 5 links:

*** /usr/testbed/devel/newbold/lib/ns2ir/parse.tcl:
    Too many links/LANs to node node2! Maximum is 4.
*** /usr/testbed/devel/newbold/lib/ns2ir/parse.tcl:
    Too many links/LANs to node node6! Maximum is 4.
*** /usr/testbed/devel/newbold/bin/batchexp:
    NS Parse failed!

the somewhat hacky fail-if-they-want-over-100mbps method, but could in the
future draw the info from the database or something if it ends up being
necessary.

First, fix up the isup generation code. When a node/OS doesn't send its
own isups, but is pingable, we need to fork and ping it, and send ISUP
when it pings. The code was there, but was broken. This fixes it. The one
time that it may cause errant messages is in modes other than MINIMAL.
When we get BOOTING, we check if it needs isup generated. If we have to
ping it, when it pings we send ISUP. This means that if we are really in
NORMAL mode, we might send ISUP before the node sends REBOOTED (or TBSETUP
in NORMALv1), and it would look funny. But that case will be really rare,
since everything that sends REBOOTED or TBSETUP has no reason not to send
ISUP itself.

Second, after mailbombing myself a couple of times, Kirk and I decided I'd
better put some throttling in the notification code that stated uses. So
now it throttles itself and digests the messages if they're sent too close
together. The first message it gets will get sent immediately. If the next
one is long enough after that, it sends it immediately too. If a message
comes too soon after sending one, we queue it up, and send it later
after enough time has passed. Currently it is set to wait 5 seconds
between messages, so it will send up to 12 per second, and wait no more
than 5 seconds before sending a message that is queued up.

(Something similar to this may be a nice thing in the rest of our stuff,
but it was made a lot easier by the fact that stated already had a polling
loop in it. Without that, you'd have to use alarms or some other weird
thing, which would be painful.)

their real hostname changes.

tests completely.

pcron has to give us the ron pem file. Not much difference anyway, and
its annoying on the new image.

testbed we've rebooted. Immediately daemonizes, then sets a signal handler
and sleeps forever. When it gets a signal to quit (on shutdown, reboot or
going single-user), it sends a state transition to SHUTDOWN to the
testbed. It installs into /etc/testbed/ .

Important note:
If you're going to use this in an image that runs the NORMAL state machine
(instead of NORMALv1, MINIMAL, etc.), the SHUTDOWN state is called
REBOOTING in that mode. Just change the appropriate line in tbshutdown,
but don't commit the change, since further use of the NORMAL mode in new
images is deprecated. Alternatively, you could change the image over to
NORMALv1 by renaming all REBOOTING tags to SHUTDOWN and changing REBOOTED
to TBSETUP.

destination was the same as hop. We don't need this since staticroutes
never puts such a route into the DB

tbnexthop.{cc,h} now contains setsockopts to install "ipfw fwd" rules.

<netinet/ip_fw.h> has changed from FBSD 4.3 to 4.5 . Because boss has 4.3,
compiling ipfw code on boss and running it on an experimental
node doesn't work. Therefore, I now have a cvs checked in local copy of
the 4.5 version of the file.

nseinput.tcl now finds the CPU cycle speed from /var/run/dmesg.boot and
passes the info to nse's RT scheduler which keeps track of real time
using the TSC. The same info can be obtained by PERFMON ioctls but the
kernel boot time measurement of the cpu cycle speed is more accurate than
what perfmon can report

These are the dirs to use on the client nodes, and should be used by
client-install targets in various makefiles.

Also add tmcd/common/GNUmakefile.in at the same time so that people do
not see errors config errors before I check it all in.

into nsetrafgen for a client install, not a regular install.
