Add a magical icon for the Emulab pages. Shows up on the tab for tabbed browsers, and
in the bookmarks, etc.

The current image isn't that great, but it's something. When we've got time, we'll
make it a little better by not trying to fit so much of the logo in at once.

what we normally do in the main map (generate a name for the node and
a CNAME for the virt name. Skip if there is a jailip, since that is
going to be handled in the private vnodes map. This means that
widearea vnodes without their own IPs will continue to get map entries
as before, but local vnodes with their own IPs will get the special
treatment and no dup entries!

stand alone (no underlying phys interface) so that both ends of a
virtual link can be on the same node.

Change "startcmd" to return the uid of the swapper, not the creator,
as the UID to run the startup command.

Get creator/swapper uid in the initial query for the node, instead of
as separate queries later. Saves some queries ...

Remove old code.

Add progagents command to return the list of program object names, and
the UID to run those objects as (again, the swapper not the creator).
This allows the program-agent startup code on the node to be more
selective in its elvin subscription, as well as running the programs
as the proper UID.

Changes to jailconfig. If the node has its own IP in the nodes table
(jailip), return that as JAILIP in the configuration for mkjail.

tunnels, interfaces, routes, and delay links. Currently in the freebsd
subtree, it will move to the common directory at some point. When used
with either -i or -u, it will also run the rc files, either to install
(-i) or to uninstall (-u). I suppose a logical option would be a -r
option to reinit (uninstall, followed by install), and that would be
easy to add. Also takes a -j option to specify a vnodeid (jail), which
does all the same stuff, but just for the specified jail node (tmcd
changed to return vnode specific data). So, this script can be used to
set up the phys node, or any single virtual node on that phys node.

Changed delaysetup to take the same options (-i, -u, -j), and I call
delaysetup from ifsetup, passing the options along.

to work inside of jails, without any extra event transmission.

This is the ports version of bind9.

NetBuild modify. Woot.

Available only to admins for now.

Link is available off "modify experiment page" in admin mode.

course; its an optional argument.

Add group stuff; we get a group (csh, tsch) and a routine maps that
into a valid path to use in the pw commands.

the vnode on whose behalf they are operating. The library passes this
through to tmcd.

Move definition of the delay_mapping file in from liblocsetup so that
it is easily exportable withou another hoop.

Add configuration support for veth devices.

Change route and ifconfig generated script to do enable/disable
segments in the generated scripts so that per-jail configurations can
be added/removed easily by mkjail.

Add program agents configuration, with corresponding tmcd command to
return the list of program objects for a node (or jail).

Trafgens inside jails talk to the local elvind, not boss.

dotunnels, doroute, doiconfig all take an optional rtabid and pass
that through to libloc routines.

Add trivial support for getting the user shell from tmcd.

is supported:

- stated listens for TBCOMMAND events, and currently handles REBOOT,
  POWEROFF, POWERON, and POWERCYCLE events. It does everything except make
  the actual calls to node_reboot and power. And it accepts batches of
  nodes instead of just single ones.

- Timeouts were added to the db for these commands, with no timeout for
  the power ones (since the node can't hang during those), and a 15 second
  timeout from reboot until the SHUTDOWN state.

- If a rebootimes out, it tries it again, up to 3 times. If it gets to
  three times without working, it sends mail to tbops and turns the
  machine off instead of continuing to reboot it. Right now I haven't
  made it do node_reboot -f or power cycle on retries, but it easily
  could.

- Stuff to be done before they work: make node_reboot send an event
  instead of doing the work, and make a new script that has node_reboot's
  old guts. Note that this requires authentication in our events for these
  commands, and a way to make sure that the command that came in as an
  event was properly authenticated.

- For future growth and expansion, it is set up so it should be relatively
  easy to add other commands that do different things, even if they take
  arbitrary params that aren't nodes or lists of nodes.

obviously doesn't get used anywhere yet.

plus the IN and CNAME records for the locally allocated virtnodes:

  pcvm82-2				IN      A       172.16.82.2
  node3.jail3-2link-full.testbed          IN     CNAME   pcvm82-2

reboot a node, we never call power directly. Instead, exit with
a status of 2 - the parent process collects a list of nodes that
needed power cycling, and does them all in one call.

combination of lans and trivial links.

for a jail node, since that must run outside the jail.
Add logfile/pidfile arguments to the delay_agent. If staring for a
jail, talk to local elvind instead of boss elvind (use the proxy).

on all DHCP events of interest.
