rather low tech approach of looking at $USER in the environment!

how we know that, so startup might have to be a special case). Runs

Package that up and send as a UDP tmcc request. Also does the account

Need to rationalize this with the isalive watchdog at some point.

disk usage metrics. This will run in a sliver, so need to assign the
metrics to the underlying pnode, and it would be better right now if
we run it only in a single sliver (the management sliver) on each node

which does run from each sliver.

(slivers). Account updates take longer of course, but thats okay for
now.

for someone since the names won't match local nodes, but not going to
worry about till it happens.

sending an ISUP. ISUP is now sent as the first event from the nse scheduler.

code to run as uid/gid nobody/nobody. I had to remove dolog(), which
was to support the oskit on the dnards, so no one will miss that!
I also removed the tar/rpm download support since we now do that via
the web interface. To support sfshostid, I had to chown/chgrp
/proj/.sfs to the nobody/nobody so that tmcd willbe able to create the
symlinks in that directory.

now mapped to more than one PC if required. The simnode_capacity
column in the node_types table determines how many sim nodes can
be packed on one PC. The packing factor can also be controlled via
tb-set-colocate-factor to be smaller than simnode_capacity.

- No frontend code changes. To summarize:
  $ns make-simulated {
    ...
  }
  is still the easy way to put a whole bunch of Tcl code to be
  in simulation.
  One unrelated fix in the frontend code is to fix the
  xmlencode() function which prior to this would knock off
  newlines from columns in the XML output. This affected
  nseconfigs since it is one of the few columns with embedded
  newlines. Also changed the event type and event object type
  in traffic.tcl from TRAFGEN/MODIFY to NSE/NSEEVENT.

- More Tcl code in a new directory tbsetup/nseparse
  -> Runs on ops similar to the main parser. This is invoked
     from assign_wrapper in the end if there are simnodes
  -> Partitions the Tcl code into multiple Tcl specifications
     and updates the nseconfigs table via xmlconvert
  -> Comes with a lot of caveats. Arbitrary Tcl code such as user
     specified objects or procedures will not be re-generated. For
     example, if a user wanted a procedure to be included in Tcl
     code for all partitions, there is no way for code in nseparse
     to do that. Besides that, it needs to be tested more thoroughly.

- xmlconvert has a new option -s. When invoked with this option,
  the experiments table is not allowed to be modified. Also,
  virtual tables are just updated (as opposed to deleting
  all rows in the first invocation before inserting new rows)

- nse.patch has all the IP address related changes committed in
  iversion 1.11 + 2 other changes. 1) MTU discovery support in
  the ICMP agent 2) "$ns rlink" mechanism for sim node to real
  node links

- nseinput.tcl includes several client side changes to add IP
  routes in NSE and the kernel routing table for packets crossing
  pnodes. Also made the parsing of tmcc command output more robust
  to new changes. Other client side changes in libsetup.pm and other
  scripts to run nse, are also in this commit

- Besides the expected changes in assign_wrapper for simulated nodes,
  the interfaces and veth_interfaces tables are updated with
  routing table identifiers (rtabid). The tmcd changes are already
  committed. This field is used only by sim hosts on the client side.
  Of course, they can be used by jails as well if desired.

There is a race there with pump and its setting of the domain
(via setting the hostname)

allows real PCs to run any OS instead of being constrained to FreeBSD. A
detailed discussion on this topic can be found in the testbed-dev mailing
list under the thread "links between vnodes and real PCs"

in the dev tree. I'm tired of problems on the mini that wastes
my time.

Changes include 2 new tmcd commands: tmcc routelist returns
the routes for all the vnodes hosted on a pnode. tmcc role
returns the role of a reserved node, like 'virthost' or
'simhost.  tmcc ifconfig now reports an RTABID field which
is calculated in assign wrapper. All the new changes
in assign wrapper will be checked in after I finish testing.

All the DB changes are in: simnode_capacity in node_types, rtabid in
interfaces and veth_interfaces. New NSE event_objtype and NSEEVENT
event_eventtype. Changed the erole field in the reserved table
to have 'simhost' instead of 'simnode'. Changed the correspoding
libdb subroutines.

did this with a simple macro called OUTPUT() that does the check and
bails from the current function. This was as boring and tedious as
life gets, but we should be protected from stack smashing now.

Also fixed up a couple cases where we take data from the client;
make sure that the sscanf calls are bounded.

pc170-1 until those nodes actually have e1000 cards installed (next week).

Need to use ethtool instead of mii-tool to do this.  My comment:

  #
  # Linux is apparently changing from mii-tool to ethtool but some drivers
  # don't support the new interface (3c59x), some don't support the old
  # interface (e1000), and some (eepro100) support the new interface just
  # enough that they can report success but not actually do anything.  Sweet!
  #

This requires that we load ethfind on the nodes, though the script will
continue to work if it isn't (though will not work for e1000 cards).

sethostname script properly sets the hostname, but sometimes that hostname
gets overridden by one of the static boot scripts which sets the hostname
back to "localhost".  The sequence is something like:
	pump runs on eth0 and fires off our sethostname script
	sethostname blocks
	ifup of eth1 starts, determines that hostname hasn't been
	  set (i.e., is set to "localhost") and remembers (NEEDHOSTNAME)
	sethostname finishes by setting the host name
	ifup of eth1 finishes, seeing NEEDHOSTNAME is set but doesn't
	  have anything to set it to so resets to "localhost"
Weird.  Hack is to make sure it never thinks it needs to set the hostname
by setting it to something that is not "localhost".  We do this once we
identify the control net interface (and thus know we will be running pump RSN).

* Download the eventkey with new tmcd call.

* Pass -k option to various agents so that they can verify the HMACs
  in the incoming notifications.

* Change program agent; The list of agents from tmcd now includes the
  command, which is written to a config file for the program-agent to
  read in. The command string in the event is now ignored.

* Build the local proxy for linux, and add the goo to start the local
  elvind and use the proxy. It has been this way on FreeBSD for a
  while, but I never got it installed for Linux before now.

Will just put this in the sup tree for now.

which had been hanging around in my home directory for a while.

There are a few new things in plab/etc/netbed_files that set up a
directory of the same name in @prefix@. This will get rsync'ed with
netbed_files/ on each planetlab node.
log/  - just needs to exist for the httpd server
sbin/ - contains thttpd, and scripts to manipulate it
www/  - the directory served by thttpd. Contains symlinks to the 'real'
        location of the rootballs (etc/plab)

I've committed a binary of thttpd - this is simply because it'd be a
PITA to compile a Linux binary for every devel tree, etc.

PLAB_ROOTBALL has now become a configure options. The idea is that we
will keep the latest version number in configure.in, but you can
override it in your defs
file. This way, we don't have to update every defs file when there's a new
version, but people can still play around with their own version if they want.

The two scripts that interact with the plab nodes skip ones that are
down. They ssh in as 'utah1', meaning that one of us who has access to
that account needs to run them, so that they can have access to our
keys. We can put boss's public key (or something) out there to remove
this requirement.

plabdist runs an rsync between @prefix@/etc/plab/netbed_files and a
file of the same name on the planetlab nodes. It's intended to be run
from the main install tree - the local rsync directory is not normally
set up in devel trees. It runs in parallel, but is limited to 4 to
avoid beating up boss too much. Takes about 1:40 with the current set
of plab nodes (took > 10 minutes doing one at a time).
