8 years ago First, let's get naming out of the way - I'm assuming that by "servers" you actually mean "cluster members". In this light, the whole cluster is an XMPP server.
How do you specify which cluster member to connect to? If by using a different DNS name, then you might end up with different MUC services running... Can you share a config file (anonymized if need be) from one of the members?

8 years ago Yes, I meant cluster members. I connect to all of the cluster members using the same DNS name, the clients are configured to try to connect to one and swap out the IP address associated with that DNS name if the connection fails as a means of failover.
Here is a configuration file (also attached in case emailing causes any formatting issues):
%%% %%% ejabberd configuration file %%% %%%'
%%% The parameters used in this configuration file are explained in more detail %%% in the ejabberd Installation and Operation Guide. %%% Please consult the Guide in case of doubts, it is included with %%% your copy of ejabberd, and is also available online at %%% http://www.process-one.net/en/ejabberd/docs/
%%% This configuration file contains Erlang terms. %%% In case you want to understand the syntax, here are the concepts: %%% %%% - The character to comment a line is % %%% %%% - Each term ends in a dot, for example: %%% override_global. %%% %%% - A tuple has a fixed definition, its elements are %%% enclosed in {}, and separated with commas: %%% {loglevel, 4}. %%% %%% - A list can have as many elements as you want, %%% and is enclosed in [], for example: %%% [http_poll, web_admin, tls] %%% %%% Pay attention that list elements are delimited with commas, %%% but no comma is allowed after the last list element. This will %%% give a syntax error unlike in more lenient languages (e.g. Python). %%% %%% - A keyword of ejabberd is a word in lowercase. %%% Strings are enclosed in "" and can contain spaces, dots, ... %%% {language, "en"}. %%% {ldap_rootdn, "dc=example,dc=com"}. %%% %%% - This term includes a tuple, a keyword, a list, and two strings: %%% {hosts, ["jabber.example.net", "im.example.com"]}. %%% %%% - This config is preprocessed during release generation by a tool which %%% interprets double curly braces as substitution markers, so avoid this %%% syntax in this file (though it's valid Erlang). %%% %%% So this is OK (though arguably looks quite ugly): %%% { {s2s_addr, "example-host.net"}, {127,0,0,1} }. %%% %%% And I can't give an example of what's not OK exactly because %%% of this rule. %%%

8 years ago In the attached config there's:
{hosts, ["localhost",
"ns1.chatserver.centos.com","45.55.54.66","45.55.57.85","45.55.60.70","45.55.60.225"]
}.I'm guessing ns1.chatserver.centos.com is the domain the clients resolve and the name gets translated to one of the following IP addresses. If that's the case, no entries other than ns1.chatserver.centos.com are necessary in the hosts clause. As it is now, depending on what the query to the server is (can you see the raw XML sent over the wire?), you might get results for different virtual hosts - hence different rooms from each of the members.
I'm just thinking out loud, so this can be wrong. If you can't take a log from the client, it's possible to change logging level on the server to 5 (also in the config) and inspect the resulting ejabberd.log. The thing to look for is the addressee of service discovery stanzas.

7 years ago Hi @Jethvasagar
Please open new issue for your problem. :)
MongooseIM version: 1.6.2 (I believe, cloned from GitHub master earlier today) Installed from: source Erlang/OTP version: R16B03-1
Hello, can you please help with a configuration issue? I would like to serve the same chat rooms across multiple servers but this is not working in my current setup, a client connected to one server does not see the chat servers created on another. What configuration option(s) would be responsible for changing this behavior?
I have clustered the servers through the mongoosectl script, the same user accounts can be accessed on all servers after only registering on one, so this part is functioning. I also have a clustered MySQL backend running across the servers(Galera). The way the clients are connecting is through a domain name, all of the chat servers have a simple DNS server that points a domain name(the same name on all servers) at localhost, then there is a script on the clients that swaps out a host entry to serve as failover, so if a server goes down, the client can just connect to the same domain name now pointing at a different IP.
