      Another CMU hack; Add a "remote" mode (-m) that tells capture to connect to · 54a55729

      a socket on a remote node instead of a local tty device. When using
      remotemode, the last argument to capture should be host:port instead
      of tty.

      Another change for CMU; they have laptops that do not power up after a · ec9ed5f7

      power cycle. For those we need to send wakeonlan packets to kick them.
      This is complicated by the fact that the laptops take an incredibly
      long time to go from poweron to a point where it will listen to a
      wakeonlan packet. No idea why. I use StateWait() to find out when the
      node hits bootinfo (which sends a PXEBOOTING event). Keep looping
      sending more wakeonlan packets until we hear from the node. Time out
      the operation after two minutes (probably need something to control
      To find the outgoing interface required by tools/whol program, I look
      in the interfces table for boss' control network.
      The mac address of the target node comes from the interfaces table.
      The flag that controls whether a node needs wakeonlan is in the
      node_attributes table:
      	mysql> insert into node_attributes set
      		  attrvalue=1, node_id='pcxxx';

      Add support for hashified/cloned filesystems. This is really only · 4bb9e149
      Leigh B. Stoller authored
      useful on widearea nodes where we can amortize the time it takes to
      copy/hash the necessary filesystems, which takes about 15 minutes.
      We would do this when a node first boots (or its image is updated I
      Note that the clone operation (when a vserver is actually created) is very fast
      though, taking about 30 seconds.
      Currently controlled by local variable $USEHASHIFIED for debugging.

      Some very basic infrastructure for generalized tools was added. · 639758e6
      Dan Gebhardt authored
      Some parts very "hacky", lots of XXX / TODOs.
      BARELY tested!!!! Don't use on the production system yet.
      Need to verify that things didn't break, especially with the automanager,
      the bgmon.pl "outage detection stuff", etc...
      See code's todos and also the file
      At this point:
       - mangerclient & automanagerclient did not change.
       - The manager, when a probe request is received, looks at the DB table
         "tool_spec" to retrieve the proper wrapperpath, formal parameter list, etc..
       - The manager assembles a message and sends it out to the appropriate
         path probers, which operate on the request as they have been
         (no major internal changes to the path probers).
       - The path probers call the toolwrapper to run the tests
       - The toolwrappers return a canonical result for that type of metric.
       - The path probers send the result and the actual parameters used by the
         tool to the data collector.
       - The data coll...

      Initial changes to support tool generalization. All command-line · caa4023a
      Dan Gebhardt authored
      arguments and result parsing handled by separate application wrappers.
      Currently fping and iperf supported.
      Not fully functional at this point: user interface needs extending
      to support the generalization, as well as getting the results back
      to "opsrecv".
      Also merged some of Mike's changes to allow for "private" managers
      to use during testing.
