Error when adding remote contact #528

DeadSix27 · 2015-04-11T15:52:40Z

Everytime I add a buddy via pidgin from a remote server using my server and request a authorization
I get this error and when I try to message that person it gives me a 404 pidgin error.

Does anyone know why this happens and or what it means?

My ejabberd version is: ejabberd 15.03.94
erl version is:
Erlang/OTP 17 [erts-6.4] [source-2e19e2f] [64-bit] [smp:64:2] [async-threads:10] [hipe] [kernel-poll:false]

If you need any more info, tell me.

Here is the log:

From what you say, it happens all the times for all the remote servers. Essentially, s2s does not work in your ejabberd server?

Does this work for you?

Depends what working means, as I get no response.
And no it seems like it only has issues on servers without a subdomain, I couln't try out much as I only know 2 servers with a user to add on.
But, the server having a domain like: "foo.bar.com" works fine, where as the server with "bar.eu" does not.
Anyway heres the, empty-output of the command u told me to use:
(I tried it once with line breaks, and once without to make sure)

I need some way to reproduce your problem in my machine, if that is possible. You have seen that a manual call to jabber.org works; does jabber.org work when you use ejabberd?

If yes, then try that manual call to another server that doesn't work when you use ejabberd.

How did you install ejabberd: binary package, git version, source package, or some distribution? And what about your erlang?

DeadSix27 · 2015-04-15T09:56:09Z

EDIT: I tried to add "test@jabber.org", then requested auth a few times, but no error messages, so that seems to work fine.

To the setup:
I cloned the ejabberd official git repo and compiled it with: (Note, i didnt pull the last change, as i doubt its anything related to this bug)

./configure --enable-mysql --enable-zlib --enable-json --enable-iconv

And used the official esl-erlang_17.5-1~~ubuntu~~precise_amd64.deb
from https://www.erlang-solutions.com/downloads/download-erlang-otp

My git version is (via apt-get)

$ git --version
git version 1.9.1

Ubuntu version is:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:        14.04
Codename:       trusty

I then added BasicAsciiUserName@NoSubDomain.eu
Everything works fine, i see the user in my list as "Not authorized"
but he never gets the request, so i pressed "Re-request authorization"
when i then check my error log in ejabberd
it tells me:

2015-04-15 11:51:52.651 [error] <0.9617.0> CRASH REPORT Process <0.9617.0> with 0 neighbours exited with reason: no function clause matching inet_dns:encode_labels(<<0,36,1,0,0,1,0,0,0,0,0,0,12,95,120,109,112,112,45,115,101,114,118,101,114,4,95,116,99,112,8,102,...>>, {4,{[<<"_xmpp-server">>,<<"_tcp">>,<<"NoSubDomain">>,<<"nl">>,<<>>],12,{[<<"_tcp">>,<<"NoSubDomain">>,...],...},...}}, 42, [<<>>]) line 693 in p1_fsm:terminate/8 line 760

PS: Im not sure but, i also tried:

inet_res:getbyname("_xmpp-server._tcp.jabber.org", srv, 2000).{ok,{hostent,"_xmpp-server._tcp.jabber.org",[],srv,2,[{31,30,5269,"hermes2v6.jabber.org"},{30,30,5269,"hermes2.jabber.org"}]}}

and replaced "hermes2.jabber.org" with the host that crashes me
but since there is also hermes2v6 (which i assume is ipv6) I don't know how to reformat it , since i dont have ipv6 on that server.

But anyway, that is all that i can think of to reproduce the error on my end.
Is there anything else you need to know?

badlop · 2015-04-15T10:10:17Z

Try to call manually inet_res:getbyname to that server that doesn't work when you use ejabberd:

inet_res:getbyname("_xmpp-server._tcp.NoSubDomain.eu", srv, 2000).

DeadSix27 · 2015-04-15T10:20:54Z

EDIT:
I also just for curiosity tried:
inet_res:getbyname("_xmpp-server._tcp.NoSubDomain.eu", srv, 2000).
With exactly that FAKE domain, and it gives me the same error,
when i then try:
inet_res:getbyname("_xmpp-server._tcp.Actually.ASubDomain.eu", srv, 2000).
it gives me the same error (unless its formatted different, when it is a sub domain, which i dont know how to format)

Ok I did that, and i got this error:

So, you are able to reproduce the problem with just a simple erlang call, and ejabberd is not involved in the problem.

I installed Erlang 17.5 i386 from ESL, and the only way to obtain an error similar to yours is to append dots at the end of the domain string. Notice that after << eu >> there is another <<>> that represents the unexpected .. I had added. In your calls, you get an error that also shows a <<>> in the end, but of course you don't add .. like I did.

If all this is correct, then it seems a problem in your machine, or a problem in the servers you attempt to connect, or a bug in erlang.

See my tests:

EDIT3:
Tried inet_res:getbyname("_xmpp-server._tcp.TestServer.nl", srv, 2000).
gives {error,nxdomain}, like before
then i tried: Tried inet_res:getbyname("_xmpp-server._tcp.TestServer.nl.", srv, 2000).
(with dot on end), gives {error,nxdomain}, then i tried with ".." (2 dots)
and then it gave the error from before.
So ye I don't know what to do, weird is just that apparently it works in the erlang shell of v18, but not in ejabberd?

EDIT2:

But yet i still get:

and now i tried:

What do you recommend i should try? Downgrading erlang?

badlop · 2015-04-15T11:50:46Z

So now the problem with a certain domain appears only when using ejabberd, not in plain erlang? Then make sure you recompile all ejabberd with the new erlang, and that the new erlang is used to run ejabberd.
Other things to try is to use a different machine to make the tests. And to connect to different remote servers.

DeadSix27 · 2015-04-15T12:01:46Z

EDIT: And yes, now its just in ejabberd, but like you see below, now i struggle compiling it.

Compilation fails now, telling me:

Compiled src/stun_app.erl
/ejabberd.git/deps/p1_stun/src/stun_listener.erl:39: type dict() undefined
ERROR: compile failed while processing /ejabberd.git/deps/p1_stun: rebar_abort

any idea?

mremond · 2015-04-15T13:10:20Z

How to you build it ?

DeadSix27 · 2015-04-15T13:13:57Z

Define "how", i built it via ssh on my ubuntu VM using git to get the ejabberd source from this repo
then i ran autogen.sh then i ran configure (see one of the above comments for details) and then i ran "make", which then returned that error once it hit the compilation of the dep. "p1_stun"

mremond · 2015-04-15T13:26:46Z

You did not tell which version you are using, but I guess you are using R18. R18 has not yet been released as an official production release. You will need to adapt the code for compliance with R18. In such case this is as easy as replacing dict() with dict:dict(), but you may run into more issue on different places. Please, stay with production Erlang release.

DeadSix27 · 2015-04-15T13:30:02Z

You didn't read the previous comments, yes i am using a non stable release, because the stable release gives crashes in ejabbed.
I'm just trying around to fix the issues I have.
I will try to edit the source to make it use dict:dict() (Edit: worked, compiled fine)

EDIT (for badlop):
I successfully compiled with R18 as ERL version and tried the
following:
i ran this in erl shell:

1> inet_res:getbyname("_xmpp-server._tcp.TestServer.nl", srv, 2000).
{error,nxdomain}

So that works? I guess it does.

Then i tried again, to add a remote contact in ejabbed
but i still get:

mremond · 2015-04-15T13:40:25Z

I perfectly read your comment. Badlop said that the problem is not with ejabberd but with Erlang + your server environment configuration. That said, it does not mean we are committed to do any work on r18 before it is released in June. Compliance will come higher priority at that time.

DeadSix27 · 2015-04-15T13:42:49Z

Alright. I just followed what he said.
Not to mention he also said:
"So now the problem with a certain domain appears only when using ejabberd, not in plain erlang?"
Which is exactly the case now...

badlop · 2015-04-16T09:52:08Z

Notice: the problem appears when using, which does not mean the problem is in. I still suspect it's related to DNS configuration of your machine or the remote servers, but as I don't know any of that part of your setup, I'm half-blind in this ticket.

Apply this patch to ejabberd:

diff --git a/src/ejabberd_s2s_out.erl b/src/ejabberd_s2s_out.erl

        of

Then trigger the problem, and let's see what do you get in the logs. I get this:

EDIT2: I can show you whatever you need to see, about the dns configs, its mostly default ubuntu and what my reseller defined.

EDIT:
Okay here are the results:

Okay, ill do that, and come back and edit my post with the results.

badlop · 2015-04-17T09:45:34Z

Great, so you got exactly what call ejabberd does to erlang and fails. If you perform that call manually, does it fail too? And does that happen 100% of the times (I mean, the same call done by ejabberd fails, and done manually by you succeeds)?

DeadSix27 · 2015-04-17T09:50:40Z

I assume i have to append a dot? lIke so:
inet_res:getbyname("_xmpp-server._tcp." ++ "serv2.nl", srv, 10000). <-- dot
I did that and get this result:

Erlang/OTP 18 [RELEASE CANDIDATE 1] [erts-7.0] [source-757dfc5] [64-bit] [smp:64:2] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V7.0  (abort with ^G)
1> inet_res:getbyname("_xmpp-server._tcp." ++ "fahrplan.nl", srv, 10000).
{error,nxdomain}
2>

Just for completeness, without dot:

Erlang/OTP 18 [RELEASE CANDIDATE 1] [erts-7.0] [source-757dfc5] [64-bit] [smp:64:2] [async-threads:10] [hipe] [kernel-poll:false]

1> inet_res:getbyname("_xmpp-server._tcp." ++ "fahrplan.nl", srv, 10000)

Can you please paste the content of your /etc/hosts file ? ejabberd is letting you add local hints in /etc/hosts for DNS resolution, but that content could interfer.
Thanks.

DeadSix27 · 2015-04-17T12:43:18Z

Here you go (note i hid my domain/ip):

$ cat /etc/hosts
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

127.0.0.1 localhost.localdomain localhost

# Auto-generated hostname. Please do not remove this comment.

xxx.xxx.xx.x subDomain.Domain.tld  subDomain

::1 localhost ip6-localhost ip6-loopback

zinid · 2015-04-17T13:53:37Z

Seems like the only way to reproduce the bug is to add dots to the end of the domain name being resolved:

5> inet_res:getbyname("_xmpp-server._tcp." ++ "serv2.nl..", srv, 10000).
** exception error: no function clause matching inet_dns:encode_labels(<<0,4,1,0,0,1,0,0,0,0,0,0,12,95,120,109,112,112,45,115,

                                                                       [<<>>]) (inet_dns.erl, line 693)

This comes from this line: https://github.com/erlang/otp/blob/maint/lib/kernel/src/inet_dns.erl#L688. According to the code, I don't see other possibilities.

Ye, its weird, as i'm not adding any dots.
