ORBIT-USER: Problem with noise generator

Hi Swapnil,

The service is up and running (and never went down). The problem is in
the old version of nodeHandler and the fact that we upgraded noise
injection service. Until we upgrade nodeHandler, you will have to issue
commands to the service directly from your script; the basic
"documentation" is available at:

Regards,

Ivan.

Subject: ORBIT-USER: Problem with noise generator

Hello.

I tried the noise generator experiment on the grid. But I got the
following errors-

INFO stdlib: 2 out of 2 node(s) still down n_1_4,n_1_3 INFO stdlib: 2
out of 2 node(s) still down n_1_4,n_1_3 FATAL run: Exception: Connection

I have got this error before as well and it means the Noise Generator is
not  up.
Can you please get the Noise Generator and antennas working as soon as
possible? I have to carry out a few mobility test experiments.
OR Is there any method to get the noise generator started?

Thank You.
