Subject: [Testbed-admins] could not connect to event server

I am trying to run a simple experiment with a single node. I couldn't
make it work.

You can see the ns file from the log at the end of this e-mail.
Some of the unique stuffs you may need to know are :
- I didn't configure the power controller so I manually power cycle my machine.
- We entered information about control and experimental switch into
the database, but the switch is not actually used.
(We will eventually use the wireless for this experiment.)
- The node type is set with the following non-default values.
(bios_waittime :300, rebootable : 0, power delay :300).

The experiment terminated while the node was in the reloading status
playing frisbee.
The major errors seen from the log file are as follows (It couldn't
connect to event-server) :

pubsub_client_connect: Could not connect to event-server:16505
event_register_withkeydata_withretry: could not connect to event server
could not register with event system
*** ERROR: tbswap: Failed to start event time.
Cleaning up after errors.

*** ERROR: batchexp: tbswap in failed!
Cleaning up and exiting with status 1 ...

**** Experimental information, please ignore ****
Session ID = 4456
Likely Cause of the Problem:
 Failed to start event time.
 ...
Cause: unknown
Confidence: 0.7
Script: tbswap
**** End experimental information ****

My questions and requests are:

1. Any comments or advices on errors observed above?

2. What are the meanings of power_delay, rebootable and bios waittime
in the node type table?

3. Does control or/and experimental switch have to be set up for this
simple experiment? We won't need the experimental switch eventually
since we are going to use only wireless for the experiment.

I would appreciate any comments.

For your reference, I attach the whole log.
