Loss of signal and SR1

Alan Banks <alanjamesbanks@...>
 

Hi all,
Does anyone know or can reason that we no longer need a restart script if signal is lost by the Ayecka IP box?
Just had a severe rain storm, previous setup required a complete PC restart after 5 mins, but I'm thinking we can just let things ride now.
Cheers
Alan

Hello,

I see more and more messages in this mailing list with extremely big empty spaces between 2 lines.
Is this my email program (Thunderbird) or is there something wrong at the mailing list side?
(Next just an example.)

Rob Alblas.
===================================

Messages received here seem "acceptable", Rob. I'm using the group via e-mail and not the Web interface, and as far as possible I try to send and receive plain text - no unnecessary HTML which is an added security risk in any case. I see my message appears to be OK on the Web view.

Google Groups and Usenet (NNTP) is the classic offender for adding blank lines....

David,

 

Of course SNMP is the way to go. But as this is not implemented in the S300E

I wanted to show an possible workaround. Maybe I looked at it too much from

the GNU/Linux side. In UNIX what you call a "bodge" is common practice and

an update of a RRD database could probably be done in one command line.

 

Stealing missed and recovered packet numbers from the TelliCast Web interface

for graphing (as far as I know it's also done under Windows) is of the same kind.

 

Cheers,

Ernst

I need to get some real figures on this. It does feel hotter than you
report, I would guess about 40C. Will report when I do.

Alan
================================

Alan,

According to a low-cost IR thermometer, when sitting on a stool with a 24 °C surface temperature, the power supply was running at 34 °C, and the unit itself at 37 °C. This is my temporary test box and sitting on a stool rather than under a shelf it is likely to be better ventilated. Access to the main box is a little more difficult, but it feels a little warmer.

Take the absolute values with a good pinch of salt!

Cheers,
David

Hello everybody,

from yesterday I face some problems with the receiving of images from MSG. Please can somebody tell me if the right name of satellite for MSG is the number 3 (MSG-3) and for RSS is the number 2 (MSG-2)?

regards,
Nikos
===========================

Correct, Nikos.

But, while RSS from Meteosat-9 (MSG-2) has it's holiday from Tuesday to Thursday this week the RSS coverage will be provided by MSG-1 (Meteosat-8). See:

http://www.satsignal.eu/software/faq.htm#msg2-to-msg3

and Q62.

David,

As far as I understand CMCS scripting mode (last chapter) it should be possible to issue a show satellite command from a Windows command shell. It's then up to us to extract from the output the things we want to update MRTG or RRDtool with. But that should be easy ...
=============================

What I would call a "bodge" (yes, I've sued such measures in the past). It will be much easier when the Novra S400 receiver is available, as it supports SNMP (as announced at the GEO Symposium).

Though I am still playing with the TBS6925. As I pointed out in an earlier message:

Instead of SNMP you can go along with CMCS for remote monitoring the S300E.

CMCS and it's manual can be downloaded here http://novra.com/support/#cmcs

Cheers,
Ernst
==============================

Ernst, unfortunately that's no use if you want to see data in the same, standard MRTG format with other systems use, so that you can directly compare with other installations across Europe.

If you do want a console monitor like CMCS, that is also available for the Ayecka SR 1 in either Web format or as a Java program.

David

Alan, I have had my Ayecka receiver running for almost a week now. I don't think it is particularly hot. Using a laser temperature probe all over the box, the maximum temperature on the top is at 32C, and 34C on the bottom.
I presume it would be a good deal hotter inside, but it seems fine to me.

Novra S300E

Alan Banks <alanjamesbanks@...>
 

Having got the Ayecka SR1 up and running without losses, I got MRTG running succesfully and removed the DVB World USB drivers and software.

Its a great piece of kit but does run very hot.

I was lucky enough to get access to one of the Novra S300E's that Gord Sawatzky brought with him from Canada to the symposium for GEO to test.

This is a smaller and slightly neater box than the Ayecka. It has only one RF input and one Ethernet port. Powered by 24V, it came with a UK wallwart and Ethernet cable.
The front is neat with logo and leds to indicate condition Power, Lock & Data.
Installation was easier than the Ayecka (though not much in it.). Novra supply from their website a management utility.
Use the instructions from EUMETSAT who also supply a configuration .xml utility.

The Novra has been installed on my portable demo system (a five + year old Vista laptop). I don't expect stellar performance and am not surprised when I got some losses over 4 hours. Most recovered.

It runs very cool due to a small fan in the rear of the device. This is running at quite high speed and the noise in an office environment is intrusive.
There is no SNMP support, so one can't use MRTG for monitoring.

Which one to chose?
I like both and if the Novra was quiet and had SNMP, I would chose it.
I like the Management utility and the lack of second Ethernet port or USB interface has no impact on my type of use. It will be an ideal unit for a demo/portable system as I have, where the fan noise is not an issue.
On my permanent setup, I will use the Ayecka. Its noiseless and has SNMP support. I find communication with the device via Telnet or PuTTY slightly cumbersome, though one doesn't need that very often. I suppose I would like to be able to attach a large heatsink to it, though the manufacturer reassures us that the unit is designed to be robust and cope with the temperature.

Either will do the job and are great pieces of kit. Here's waiting for the new S2 data stream.

Cheers
Alan

Folks,

I am developing some Web pages showing the performance of a few DVB-S2
receivers. For once, we have "real" numbers for SNR rather than meaningless
percent, and real numbers for link margin which show how near to the
threshold your signal is. I've included some TelliCast loss graphs as well.

http://www.satsignal.eu/mrtg/performance_eumetcast-europe_snr.php
http://www.satsignal.eu/mrtg/performance_eumetcast-europe_link_margin.php
http://www.satsignal.eu/mrtg/performance_eumetcast-europe_losses.php

The TelliCast losses are almost all caused by the receiver or
receiver/processing PC, and not by the IP receiver itself. As mentioned
before, there are usually a few packet losses throughout the day at the
uplink end, and these are almost always small and with an equal number of
missed and recovered packets.

John Say's installation at Cullercoats has an interesting packet missed &
recovered characteristic which needs further investigation, but the lost
packet events are still few.

Please contact me if you would like your data added.

Cheers,
David

David and everyone,
 
Here is the way I finally set up my reception installation using the Ayecka SR1:
Receiving PC – Acer i7 Windows7 64bit connected direct to traffic port
Management PC - Modified Dell Dimension 5000 Pentium 4 Windows 7 32bit  connected direct to management port and usb port
Helpful programs: Claridion MRTG CFG Creator v1.05 which has a useful snmp browser which will create single *.cfg files for any OID
                              Hilgraeve HyperTerminal v7.0. Less complicated than PUTTY.
Using HyperTerminal, set management address to 192.168.10.99/255.255.255.0 and traffic address to 192.168.10.102/255.255.255.0, set to isolate in the network menu: on the system menu set to public (default is 0).
Use MRTG CFG Creator to create *.cfg files for these addresses and for the OIDs.
Seems to work even though it is not strictly as set out in the EUMETCAST advice but is closer to Ayecka’s manual.
 
If in difficulty Ayecka are very helpful and patient.
 
Finally a special thanks to David for his patience in helping this old duffer get his head round the mysteries of networking.
 
Regards
John
