#789 Saros can't connect through Google Talk

[Daniele Segato]

Hi,

I've installed Saros plugin on Eclipse Indigo.

I'm trying to connect it with my gmail account:

my.email@gmail.com

server: talk.google.com
port: 5223

The informations provided in faq about the server configuration are wrong: http://www.saros-project.org/faq#Can_I_use_Saros_with_my_Google_T

you must provide a port or the wizard will not let you close it.

I tried both with talk.google.com server both with gmail.com (as the FAQ say)

I can't connect.

This is the log...

If this is not a bug but just a configuration issue please provide the right setting I have to use / fix the FAQ.

Thanks

Just leave the server and port field blank and all should went well.

[Daniele Segato]

Hi Stefan,

you are right, it works with my private gmail account.

Then I have another issue.

I think the software is matching @gmail.com to know which servers to use, I need to manually specify.

My company use Google Apps and we have an account with custom domain

my.email@customdomain.com

it has all services available to google users (including gtalk).

How can I configure it to use gtalk services with my customdomain.com account?

Thanks

[Stefan Rossbach]

What happens behind the scene is a simple DNS query

_xmpp-client._tcp.gmail.com SRV service location:
priority = 20
weight = 0
port = 5222
svr hostname = alt4.xmpp.l.google.com
_xmpp-client._tcp.gmail.com SRV service location:
priority = 5
weight = 0
port = 5222
svr hostname = xmpp.l.google.com
_xmpp-client._tcp.gmail.com SRV service location:
priority = 20
weight = 0
port = 5222
svr hostname = alt1.xmpp.l.google.com
_xmpp-client._tcp.gmail.com SRV service location:
priority = 20
weight = 0
port = 5222
svr hostname = alt2.xmpp.l.google.com
_xmpp-client._tcp.gmail.com SRV service location:
priority = 20
weight = 0
port = 5222
svr hostname = alt3.xmpp.l.google.com

If the customdomain SRV are correctly configured you can just
use "my.email@customdomain.com".

If this does not work you must find out the correct host address and port
by yourself.

As you see xmpp.l.google.com = talk.google.com ... you picked the wrong port.

[Daniele Segato]

Hi Stefan

thanks for your quick response.

I tried with my custom domain

user: my.user@customdomain.com
server: talk.google.com
port: 5222

When I try to connect it immediately fail (no timeout)

I think this may be related: bug 733... http://sourceforge.net/p/dpp/bugs/773/

The only official doc about Google Apps user + gtalk is this: http://support.google.com/a/bin/answer.py?hl=en&answer=49147

And someone report weird behaviors: https://nealpoole.com/blog/2010/11/how-to-properly-configure-pidgin-and-google-talk/

Can I help by enabling some debug log in some way?

[Stefan Rossbach]

According to http://support.google.com/a/bin/answer.py?hl=en&answer=49147

just using my.user@customdomain.com as JID without any server options should be enough.

If you look at the log file you will see some SASL exceptions if the username is not valid.

The current problem I have is:

For the normal Google Accounts your

login name is: foo@[gmail.com|googlemail.com]

but I do not know if Google Apps Accounts also must be suffixed by the domain.

E.G my.user@customdomain.com

Where the user login name is: my.user@customdomain.com
and the domain is: customdomain.com

We internally split the JID, so using foo@bar.com with server foobar.us

will become:

Login name: foo
Domain: bar.com
Server: foobar.us

Hi Stefan,

I see..

in the log I see this:

!ENTRY de.fu_berlin.inf.dpp 4 0 2013-03-05 13:55:38.771

I disabled SASL in advanced setting and I could login!

What are the conseguences of disabling SASL?

I'm pretty sure the Username / password are correct so I suspect the issue may be what you say: google may be expecting the Login name to include the @domain part.

[Stefan Rossbach]

As long as you have TLS enabled there is no problem, as you can see only SASL PLAIN is used, so it even does not matter.

I am just wondering why SASL Auth fails, but works fine without using it.

[Daniele Segato]

Let me know if I can do anything to help you discover it

I can even test with some custom plugin you pass me ;)

[Stefan Rossbach]

Seems to be a bug in the buggish Smack API

http://community.igniterealtime.org/thread/46624

Seems to affect SASL Plain as well.

Thats the reason we must suffix the login name to avoid authentication failure.

[Daniele Segato]

Stefan, would you like me to open another bug report?

I think this is the exact thing the user was trying to say to you on bug #733

[Stefan Rossbach]

As we do not tend to self patch 3rd party libraries I think this would not be very helpful.

There is also a bug in Smack that will prevent the usage of Socks5 via GTalk.

http://community.igniterealtime.org/message/226175#226175

You can open as many bug reports as you like but be prepared that they will be closed
with the same answer: defect in 3rd party library.
