the hosts files that we put on free nodes. For reserved nodes, we
start a new hosts file from scrath, and qualify localhost with
the domain found from the hostname command.

clients so they can create a proper .forward file. 2) Add some
test code for seeing how feasible it is to do accounts on ops/tips
using tmcd instead of direct ssh. Initial results are not good; too
many accounts; does not scale well. Going to need a smarter protocol
for doing hundreds of accounts, but I will leave this code in place
for now. Note, unlike testbed nodes, control nodes must connect with
ssl.

Add better timeout handling code to tmcc, which watches for progress
instead of just dumping after the timeout. This lets really slow
connections proceed okay, but still timeout out if nothing happens at
all.

This new tmcc has been installed into the sup trees for WIDE and RON.

parameters). Install target update as well.

directory unless the "root" directory (where we mount the vnode
filesystem) is empty! If its not, do not try and remove anything,
since it means something went wrong with the teardown. This will make
Russ happy; his homedir won't disappear on a regular basis.

file instead of contacting tmcd directly to find that info.
Basically, cut out 4 places where we contact tmcd on boot. I know, big
whoop.

bunch of jail changes. No matter, no one should be installing any of
this stuff to make a new image until I give the okay.

own script. It was just clutter in that library. Kill delay_update
since its not really used anymore, but give a delaysetup a -u option
to do that, just in case.

but eventually did not use it. Current images still make a call to it
from libsetup but will get an empty string that doesn't affect anything.

Move bootvnodes to after ISUP so that the os_setup waits for the right
thing at the right time.

partition. Does the usual fdisk, disklabel, disklabel edit, newfs,
mount, and fstab edit. Right now called from bootvnodes to make up a
giant /var/emulab/jails whenever jailed nodes are used. This script
requires a fair amount of error checking to be added before it could
be considered generally safe for users.

ntpdrift values reported from most nodes. Do not report ntpdrift from
the MFS either. Clean up pidfile stuff, and add better "stop" mode for
shutdown.

created by libsetup are now created in /var/emulab/boot; nothing is
written into /etc/emulab or /usr/local/etc/emulab anymore. This was
a requirement for jails, but is also a good thing to do anyway.
There are a number of jail config changes to support the old vnodes
and the new style jail vnodes; specifically, a setup routine to called
from inside the jail when it first boots up to the get the usual
assortmant of config info from tmcd. Also Merge local and remote
update routines into one. Other various little changes for SFS and the
MFS.

replace it eventually). Like the ron nodes, local nodes will now
periodically (once every 5 minutes) send a udp packet to boss to
indicate the node is alive and to see if it needs to check for account
updates. This will replace the once every 5 minute fping we do from
db/node_status (once I whack that script), and will simplify the
existing problem of propogating accounts to nodes (nodes down, nodes
in the swapping phase, etc).

we make, into these makefiles cause we tend to forget things! Also
chain to other makefiles as appropriate, including those in the event
directory and elsehwere to install client side programs and the like.

now used on local nodes. Possibly appropriate for linux too, since
this is mostly just a big wrapper for other scripts.

running (or were running when the node rebooted), and fires them off.
Called from rc.setup.

supfiles into .in files to be run through configure.

well; do not use a tmcd timeout, but block until tmcd responds.

directories into a common subdir. Also cleaned up some.

client side code. Two new files, to be included by any client side
script, which define all the paths. For /bin/sh scripts:

	. /etc/emulab/paths.sh

and for perl scripts:

	BEGIN { require "/etc/emulab/paths.pm"; import emulabpaths; }

Each defines a number of variables: ETCDIR, BINDIR, VARDIR, BOOTDIR,
LOGDIR, and LOCKDIR. They also set the path properly for the script.

This gets rid of the different hardwired paths, and reduces it to just
one for everyone.

use perl dbm code.

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

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.

  - Fixes the routing problem
  - A new type "sim" has been created but not in the DB. node_types and
    nodes remain unchanged. This will change after we figure out how
    to represent in the DB the local multiple virtnodes in one phynode case
    The frontend tb_compat.tcl adds the sim type and ptopgen associates
    a huge number of sim nodes to all local PCs.
  - All simulated nodes go into one pc untill I finish coding the distributed
    nse case. Also, sim nodes go through assign but with an explicit
    "fix-node" directive in the top file. A random free pc is chosen using
    the avail script in assign_wrapper. If we don't fix node it, assign
    maps sim nodes to multiple phy nodes even when a valid all to one
    mapping is possible.
  - Syntax for nse:

   $ns make-simulated {

       set simnode1 [$ns node]
       set simnode2 [$ns node]

   }
   ...

   The old syntax

   set nsenode [$ns nsenode]
   $nsenode make-simulated {
   }

   is deprecated

  - All 38 frontend tests in the testsuite pass

  - A new table v2pmap has been added to handle multiple virt nodes to
    one phy node mapping. This is used in "tmcc hostnames" currently.

  - The phy node that is picked to run nse is loaded with a custom image
    FBSD45-NSE . This can use the default FBSD kernel if there is a mechanism
    to run at 1000HZ, have options IPFIREWALL_FORWARD and PERFMON turned on.
    The image is in the 'testbed' group. Do not delete this image.

  - Static routes now adds routes for the case dst == nexthop. The routing
    graph would be disconnected otherwise and I need to traverse this in
    assign_wrapper for nse. On the client side, such a route is filtered out in
    libsetup.pm

  - sim nodes are also correctly visualized

jailed environments.
Fix up sfs stuff so that warnings and errors from sfskey do not
get printed out on the console.
Add a jailedsetup stub for testing with jails; work in progress.

rc.ifc uses it unconditionally so it needs to exist.

on the RON nodes and in the new widearea image.
