      Massive reworking of our structure for defs files. · 09eb5852
      Mac Newbold authored
      Before:
      The main defs file (ie for configure) had an entry for WWWDEFS that
      pointed to a <@WWWDEFS@>-defs.php3 file in the www/ directory. The www
      defs file loaded some values about web pages, URLs, and some web
      configuration parameters.
      
      Problem:
      Anything that was only in the www defs file was not accessible in the rest
      of the universe (ie perl, C, and any other non-web-page scripts). For
      instance, you couldn't have a perl script send an email to a user with a
      link to the web site.
      
      Solution:
      Nuke all the www-defs files, move any important values into the main
      configure, and change the web defs infrastructure to respect that. This
      also meant adding about 3 lines each to all of the configure defs files.
      (There really are about 10 new values you can change in your defs file,
      but in almost all cases, the default values are the right thing.)
      
      Upgrading:
      External sites will need to move a few variables from their www-defs file
      into their configure defs file. The example file should make it pretty
      obvious. They may also want to customize some of the other vars that are
      mentioned in configure.in and www/defs.php3.in .

      New version of unified tbswap in/out.
      startexp/endexp/swapexp have been changed to use new script.
      
      tbswapin and tbswapout have been replaced with a script which
      spits out a warning message, then calls tbswap appropriately.
      
      The README has also been modified.

      A few changes to stated: · 92fa4ae2
      Mac Newbold authored
       - fix bad indenting to a uniform 4 spaces (before was 2, 4 and 8 mixed)
       - Move ping-for-isup functionality into a separate script
       - Make sure every transition triggered by stated (directly or indirectly)
         sends an event, instead of taking shortcuts.
      
      This called for a new script, eventping, which just pings until the node
      is pingable, then sends an ISUP event. Stated runs this in the background
      where necessary, and nothing else should run it.
      
      Adding eventping meant modifying configure and the utils makefile, too.

      New script: readycount · 616601b5
      Robert Ricci authored
      Simple command-line interface to the ready bits. Its primary
      purposes are:
      
      * Manually report ready for nodes that can't do it themselves
      * Get a list of which nodes are ready, so that you can figure out
        which one(s) aren't reporting in
      * Clear ready bits so you can use them again without restarting the
        experiment
      * Make it possible to poll ready bits on boss/ops

      Add stuff to update the SFS keys on the fileserver after someone uses · cc1c4e54
      Leigh B. Stoller authored
      the web page to add/delete a key! Nodes were getting updated, but
      the SFS server was not cause there was no program to fire the new keys
      over there.
      
      The operation is currently simple. sfskey_update on boss constructs a
      new sfs_users file. Then it runs sfskey_update.proxy on ops (vis ssh
      of course), and gives it the new file via stdin. The proxy creates the
      .pub version from that file, and then moves the two new files into
      place in /etc/sfs. I employ the same locking stuff that Rob did in
      exports_setup and named_setup to prevent multiple updates from
      stacking up. Not likely, but might as well. Also note that the entire
      file is regenerated. When we get 5000 users this might have to change
      a little bit!
      
      Also changed mkacct slightly. Instead of doing a "sfskey register" on
      ops after generating the new key, just add it to the DB. Then fire off
      an sfskey_update to push the new keys over. Also add a -f flag to
      mkacct for use from the web page to indicate that the user has changed
      his SFS keys. Note that mkacct should probably take a series of flags
      since we have it as a wrapper for several things. Or maybe split all
      this stuff up.

      Merge the newstated branch with the main tree. · 5c961517
      Mac Newbold authored
      Changes to watch out for:
      
      - db calls that change boot info in nodes table are now calls to os_select
      
      - whenever you want to change a node's pxe boot info, or def or next boot
      osids or paths, use os_select.
      
      - when you need to wait for a node to reach some point in the boot process
      (like ISUP), check the state in the database using the lib calls
      
      - Proxydhcp now sends a BOOTING state for each node that it talks to.
      
      - OSs that don't send ISUP will have one generated for them by stated
      either when they ping (if they support ping) or immediately after they get
      to BOOTING.
      
      - States now have timeouts. Actions aren't currently carried out, but they
      will be soon. If you notice problems here, let me know... we're still
      tuning it. (Before all timeouts were set to "none" in the db)
      
      One temporary change:
      
      - While I make our new free node manager daemon (freed), all nodes are
      forced into reloading when they're nfreed and the calls to reset the os
      are disabled (that will move into freed).

      Add a new script: tbresize · 0dd12dba
      Mac Newbold authored
      (installs into /usr/testbed/bin/tbresize but isn't avail. on ops yet)
      
      Usage: tbresize [-d] -a -e pid,eid -n num -t type [-p prefix]
             tbresize [-d] -r -e pid,eid <node> [<node> ...]
             tbresize -h
      Use -h to show this usage message.
      Use -d to enable extra debugging output.
      Use -a to add nodes to an experiment.
      Use -r to remove nodes from an experiment.
      Use -e pid,eid to specify the experiment to resize.
      Use -n to specify the number of nodes to add.
      Use -t to specify the type of the nodes to be added (pc, pc850, pc600,
      etc).
      Use -p to specify a prefix for vnames (i.e. "node" => node0 .. nodeN).
      With -r, specify a list of one or more nodes to be removed (i.e. pcXX).
      
      Can even resize an expt down to no nodes then back up again. If it has
      one LAN/link in the expt, it adds the new nodes to it. If it has zero or
      more than one, it doesn't connect the new nodes to the topology.
      
      After finding and reserving (or before freeing) it fixes up the right
      places in the db and reruns snmpit, then reruns exports_setup and
      named_setup and reboots all the nodes that are now in the expt so they get
      updated configuration data.
      
      Even visualizes properly after being resized, the only catch is that the
      ns file is the original one, not one generated from the db.
      
      Use it, abuse it, have fun with it, and let me know what breaks.

      Changes to sshtb. Remove sshremote, and convert sshtb into a perl · 231fc2b1
      Leigh B. Stoller authored
      script that checks the database to see if local or remote. The problem
      with this is that the ssh syntax makes it hard to determine the host
      name by inspection. Would need to parse all the ssh args (bad idea),
      ot work backwards and try to figure out the difference between the
      command (which is not a string but a sequence of args) and the host
      and the preceeding ssh args. Hell with that! Changed sshtb to require
      a specific -host argument. Read the args and look for it. Error out of
      not found, to catch improper usage.
      
      The moral of this update: "sshtb [ssh args] -host <host> [more args ...]
