I don't know what an "Active Installation ping" is, but in fact while I seem to
be able to access this webpage:
$ curl http://extensions.xwiki.org/activeinstalls
{
"status" : 200,
"name" : "Bobster",
"version" : {
"number" : "1.1.1",
"build_hash" : "f1585f096d3f3985e73456debdc1a0745f512bbc",
"build_timestamp" : "2014-04-16T14:27:12Z",
"build_snapshot" : false,
"lucene_version" : "4.7"
},
"tagline" : "You Know, for Search"
}
$
I cannot `ping` it:
$ ping extensions.xwiki.org
PING www.xwiki.org (104.31.71.57) 56(84) bytes of data.

Does the Distribution Manager execute a real "ping" command even though the
webpages are accessible? And if yes, how can I avoid this? I doubt that our networking
dept. will adapt any gateway configuration to to make a single software installation
possible :-}
No, there is no ping or such; well, it relies on the library: "HTTP
Components": https://hc.apache.org/ to do the job.
I have to admit that I do not know exactly if this library does or does not
send a ping first, but I do not think it does.
Even if it were so, it is not the case of the problem, as I cannot ping
extensions.xwiki.org either, and install works from here.
The "timeout" error message seems to indicate that the connection never gets an
error but is simply dropped somewhere.
I do not think extensions.xwiki.org drops the connection - as you can get there
via curl ...
Any chance the application server uses some proxy settings, as described at the
following link, but they happen to be incorrect?
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HRunningXWikibehindproxy-server
That might explain the timeout despite the server being able to reach the
installation repositories normally (i.e. via curl).
The application server doesn't use any proxy settings: I haven't set any
and I doubt that they are configured by default :-). However I'm
currently trying to find out, if our network has any limitations
regarding outgoing network traffic
I have to admit that if it is not the proxy-settings then I am getting somewhat
desperate about how to diagnose the problem.
I guess one could try to get stack traces from the server while it is starting
up
and use the java option "-Djavax.net.debug=all" (dumps lots of stuff to the
standard output) to see if it tries to open connections to extensions.xwiki.org
but I guess all one can get from that is that the server opens connections and
then it waits till timeout ...
I've done this through setting the environment variable $JAVA_OPTS to
"-Djavax.net.debug=all" prior to running $tomcat_home/bin/catalina.sh.
Is that the right place? I also set the following loggin levels in
$tomcat_home/conf/logging.properties:
java.util.logging.ConsoleHandler.level = FINEST
1catalina.org.apache.juli.AsyncFileHandler.level = FINEST
Also added
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter =
org.apache.juli.OneLineFormatter
org.apache.http.level = FINEST
org.apache.http.wire.level = SEVERE
to $tomcat_home/conf/logging.properties (according to
https://hc.apache.org/httpcomponents-client-ga/logging.html) but still
not seeing the wire output. where should I find it?
