[AG-TECH] AG connection problems (AGServicemanager)

[Alexander.Kuzan at gmx.net]

hi everyone

I'm a computer science master at the university of switzerland in zurich and
I'm setting up a test environment with two AG nodes. I have the systems up
and running, I did a standard
+installation of RH7.3 with all updates as of today (Mon Aug  4 09:42:15
CEST 2003) and I installed the AGTK 2.0 from the main AG site.

got a certificate, created grid-proxies and all on all the machines, and
started AGServiceManager.py on all of them (1 audio, 1 video, 1 display). now my
problem:

when I run the AGNodeService.py and the NodeManagement.py on either windows
or linux, and try to connect the audio and video machines, I sometimes get an
error:

Exception: Service Manager is unreachable
https://audio1:12000/ServiceManager

but it's not on all machines, and it's not all the time. I don't know what
it is... can somebody help me with this ?
for instance, I can connect to the audio machine, but the video machine is
unreachable, and the other way around.


see the log of the agsm below

thank you for your time and effort
I really appreciate it

alex
