[App_rpt-users] Allstar connecting to Echolink Problem

[Kent Ochs]

I too have been experiencing some inbound connection problems with Echolink.  This only effects certain Echolink users but not others user, who at the same time are able to connect without problem. After restarting our system, the problem does go away


I had a chance the other night to do some troubleshooting with a user who was having trouble connecting to our system.

Running the Asterisk remote console, I saw his connection attempt and failure.  The attempted Echolink connection lookup was by his IP address.

1.  I confirmed that his IP address was valid.
2.  I confirmed that his Callsign/IP was not in the local Allstar Echolink database.

What was interesting was I could not lookup his Callsign on the Echolink Database Server either, but he was able to connect directly to my personal computer, so he was authenticated somehow to the Echolink system.

3.  After 5 minutes he did show up in the Echolink database I was looking at (Shown at the top of the Echolink database lookup screen as nawest.echolink.org)  

4.  After a server restart he was able to connect my Allstar Node.

What I did notice was that there is a naeast.echolink.org database server that is not in my server list.

Here is what I think is happening.

1.  I'm not sure which database the sync runs against.  (First one in the server list?)
2.  If a call/ip can not be authenticated local, then a separate lookup occurs against each server in the Server List.
3.  If the user has authenticated to an Echolink server not in the Server List (like naeast.echolink.org), this individual Echolink database lookup process will also fail.


It appears the sync process between Echolink database server is a little longer than the stated 20 seconds stated by the Echolink folks.

So, if  a user connects to an Echolink server, other than one in your server list.  There may be a significant delay from the time the user shows up in the Echolink database and is finally downloaded to the local copy on the Allstar server.

I have added naeast.echolink.org to the list of recommended database servers in the Servers list and I am waiting to see if this solves the problem.  (Is Echolink load balancing first to nawest and naeast?  Are they having sync delays and/or problems?)


Then again perhaps there is something wrong with the local Echolink database sync process that restarting the server fixes.  I sure would like to know what Echolink database server the sync process connects to by default.

Thanks
 to those that responded... i had waited several hours/days without the 
node appearing active and do not have a second client running 
simultaneously within my network. The later responses indicated the 
search for my node failed to find a match, but that was because the 
wrong callsign was used. See below.


cruiser*CLI> echolink dbget c N9JPG-L
960818|N9JPG-L|71.194.253.53

>> Below that is my 
echolink.conf file for reference. Note the servers listed - 1,5,3. 
I used these in my conf file as it noticed that was what my echolink client was using.

server1=nawest.echolink.org
server2=nasouth.echolink.org
server3=servers.echolink.org

>>Make 
sure you point the echolink ports in your router to your allstar server 
and as was mentioned you can only run one echolink node per public IP 
address.


As noted earlier, that is all set as suggested on the howto page for allstar to do echolink.

Any other ideas?
