ORBIT-USER: Noise injection

[Ivan Seskar]

Just a minor "firewall" issue; can you please try again.

Ivan.

Hi,
 
I cannot connect to the noise gen using the web service. It just tries
connecting and then gives up
 
Output from console:
 

shivesh at console.grid:~$ wget
'http://instrument1.orbit-lab.org/initialize'
--09:58:46--  http://instrument1.orbit-lab.org/initialize
<http://instrument1.orbit-lab.org/initialize> 
           => `initialize'
Resolving instrument1.orbit-lab.org... 10.3.0.15 Connecting to
instrument1.orbit-lab.org|10.3.0.15|:80.. . 


Any clues on what might be the possible problems ?
 
Thanks
 
Shivesh

	Because of the "enormous pressure" we decided to push for an
"early"
	release one of the two noise injection services. However, it is
far from 
	being ready for the prime time - we are sure there will be quite
a few
	bugs to deal with so please be patient and let us know about any
	problems (in other words: use at your own risk :-) ).
	
	The vary basic instructions for using it are at: 
	
	http://www.orbit-lab.org/wiki/Documentation/ArbInterference .
	
	As you can see from the page this service is really exposed in
the very 
	basic form. We will try to get better (i.e. "experimenter
friendlier")
	interface ready as soon as we finish basic calibration which
shouldn't
	take to long. Having said that, it will take quite a long time
to 
	calibrate everything (especially all of the wireless devices)
which is a
	prerequisite for fine tuning the topologies.
	
	Also please don't assume that you know the state of the
interference
	injection; in order to avoid unpleasant surprises the safest bet
is to 
	explicitly turn the interference off at start and end of your
slot by
	issuing
	
	wget http://instrument1.orbit-lab.org:5012/interference/stop 
	
	(whether you use interference injection in your experiments or
not).
	
	Happy experimenting,
	
	Ivan.
	
	PS: Fully distributed noise injection (with 100 noise sources)
is at
	least 3 months away due to "manufacturing" problems. 
	
	PPS: We need a better name for this service so if you have an
idea ...
