Dear all,

I’'ve problem with my wildfire version 3.0.1, Error log:

2006.07.25 14:39:08 org.jivesoftware.wildfire.server.OutgoingServerSession.createOutgoingSession(Out goingServerSession.java:259) Error trying to connect to remote server: gmail.com(DNS lookup: xmpp-server4.l.google.com:5269)

java.net.SocketTimeoutException: connect timed out

at java.net.PlainSocketImpl.socketConnect(Native Method)

…

I’'ve no problem with my net connection

jefri@phoenix:~/wildfire$ telnet xmpp-server3.l.google.com 5269

Trying 216.239.37.125…

Connected to xmpp-server3.l.google.com.

Escape character is ‘’^]’’.

Java version is 1.5 update 5, OS Debian Sarge 3.1

Thanks for your respons

What DNS are you using? Wildfire has issues with certain domain name servers that can’'t handle class=any requests.

Seems to me that there might be a firewall that blocks access to xmpp-server4.l.google.com:5269. Have you tried:

$ telnet xmpp-server4.l.google.com 5269

The one you tried was mistakenly:

$ telnet xmpp-server3.l.google.com 5269

they’'re using round-robbin for that:

$ dig -t srv xmpp-server.tcp.gmail.com

; <<>> DiG 9.2.2 <<>> -t srv xmpp-server.tcp.gmail.com

True, and maybe you’‘re right about the class=any issue. But the given log shows (DNS lookup: xmpp-server4.l.google.com:5269). IMO, Wildfire would have had the IP for that host, or is it not? I’‘m just wondering where could be the point of failure. BTW, I’'m not an expert on DNS.

i think i’'ve found two problems,

First, i try to sent message to my buddy ***@phoenix.ui.ac.id and i got error message like this

2006.07.26 14:19:18 org.jivesoftware.wildfire.server.OutgoingServerSession.createOutgoingSession(Out goingServerSession.java:259) Error trying to connect to remote server: id(DNS lookup: id:5269)

java.net.UnknownHostException: id

After that, i try to sent another message from my account @gmail.com and i got error mesage like this

Socket[addr=/64.233.166.129,port=19581,localport=5269]

2006.07.26 14:15:02 org.jivesoftware.wildfire.net.BlockingReadingMode.run(BlockingReadingMode.java:1 04) Connection closed before session established

Did you ever get this solved jefri? I am seeing the same thing on our server.

with google in particular and possibly other publicly accessible servers, it’‘s important that the remote server be able to contact your server with your server’'s xmpp domain setting.

so the question is not so much whether your server can contact google’'s but vice versa. you can modify your xmpp domain name in the jiveProperty table.

i have s2s working with google talk contacts with the following setup:

  1. xmpp.domain

wildfire server ip address 192.168.1.100

wildfire xmpp.domain = jabber.mydomain.com

added following line to /etc/hosts

192.168.1.100 jabber.mydomain.com

added DNS entries for jabber.mydomain.com to point at my firewall address (most ISPs have some kind of web interface to do this nowadays)

  1. domain gmail.com whitelisted from wildfire console

  2. firewall config

jabber.mydomain.com resolves from the internet to my firewall address

ports 5222, 5223, 5269 open and forwarded to 192.168.1.100
