Thanks, Jason.
My command was that.
dbeacon -4 -n "NFRI-AG-Server" -b ipv4.dbeacon.aarnet.net.au -O -a
sic...@netmedia.gist.ac.kr -C KR
However, I couldn't find my host name in 'Multicast Beacon' matrix.
Is that any problem in my command?
'The Multicast not available site problem' could be the factor of this problem?
However I can see 'Multicast Available' button in the 'Venue Client'. In
multicast not available site, is it possible?
Regards,
Sangil Choi.

Dbeacon does work on Fedora 12, as I have just tested it. When you say "your"
host name was not updated on the webpage, what was the command you were using
to execute dbeacon.
I suggest running it using something like:
dbeacon -4 -n "[your display name] -b ipv4.dbeacon.aarnet.net.au -O -a
[your email address] -C [country code]
For example, I issue the following myself
dbeacon -4 -n "CQU (Jastest)" -b ipv4.dbeacon.aarnet.net.au -O -a
j.b...@cqu.edu.au -C AU
Hopefully that should work for you.
Additionally, I can see your entries with the NZ beacon
(http://beacon.karen.ac.nz/), which shows that you 2 machine can communicate
between each other using multicast, but fails to communicate with other beacons.
Note: a Blind beacon is when a beacon cannot talk multicast is any other
beacon. For example, if you stop "nfri-ag-server.gist.ac.kr", than your other
beacon (nfri-ag-display.gist.ac.kr) will become a blind beacon.
Hope this information helps.
Regards,
Jason.

Thanks, Jason.
First, I installed the 'dbeacon' and started. However my host name was not
updated in web page and the 'Venue Client's 'Multicast Not Available' button
was enabled. In Fedora 12, 'dbeacon' does not works?
So, I try using the New Zealand beacon. In the 'Venue Client', 'Multicast
Available' button was enabled. However, in matrix, my host was printed in
'Blind Beacons'.
I changed my '/etc/beacon.conf' file like bellow.
==============================
GROUP = 233.176.75.32
CONTACTNAME = NFRI-AG-Dispaly
CONTACTINFO = 000-000-000
CONTACTLOCATION = korea
NOTIFYEMAIL = sic...@netmedia.gist.ac.kr
OUTPUTDIR = /var/lib/beacon
CENTRALSERVERNAME = beacon.karen.ac.nz
===============================
Is that right?
Regards,
Sangil Choi

Sangil
We now use dbeacon within Australian, as the aarnet beacon server is no longer
running.
See http://www.accessgrid.org/node/1998 for install instructions for dbeacon
for Fedora 13.
Alternatively, you could try using the New Zealand beacon which can be found at
http://beacon.karen.ac.nz/.
Cheers,
Jason.

Thanks, John.
I checked my client and server and I find that multicast beacon is not
installed. I treat that and I show the ‘Multicast Available’ on the venue
client. After that, the client can show the bridge but that is in different
networks(Bridge's in 210.x.x.x / Client's in 203.x.x.x). Unfortunately, the
same problem still remained.
Can you send me your '/etc/beacon.conf' file?
In addition, is the aarnet beacon server works well?
I couldn't open aarnet beacon server's web page(http://beacon2.aarnet.net.au).
So I doesn't see the 'multicast beacon table'.
I would appreciate your help with this.
Regards,
Sangil Choi.

제목: Re: [AG-TECH] All client in same venue use same bridge?
Sangil,
It's simple reason why this is the case: If two bridges do not have
multicast connectivity between them, then the traffic between the two
bridges can not reach each other.
On the same bridge, you can be sure everyone is connected to the same
traffic; but, if on different bridges - currently there is no way to be sure
that the multicast traffic reaches between bridges without testing.
Currently, there is no way without just testing which bridges do this - and
sometimes the networks change between sites that multicast breaks and until
reported isn't fixed.
For an event, I will typically (if required) suggest which bridge sites
should utilize if they aren't multicast capable that I know can work between
bridges. *most* of our sites here are now multicast enabled however, so we
try not to rely on bridges at all.
note: be sensitive to using other people's bridges because that will incur
extra traffic on their network (if for large # of clients and bandwidth,
this could be a problem for some sites hosting bridges without them
realizing it).
We have 'internal' bridges in our state where we have our own registry that
we only give out to our Louisiana site nodes so they only show up for our
clients. Very useful way to take advantage of the registry feature.
