Connection refused to host

The answer is most likely in the logs (/var/opt/open-xchange/open-xchange-admin.log.0)

RMI authentication is enabled

Hi friends, i dont speak deutsch,neither english, but this seems quite similar to my case,because i can not register the server, could it be rmi related?

This is the message:

com.openexchange.admin.rmi.exceptions.PoolExceptio n: DBP-0001 Category=5 Message=Cannot get connection to config DB. exceptionID=383039001-1

i'm using spanish translation of debian etchand the sun java sdk, becuse i use my pc to make sales presentations of the open source advantage and so on

this is the history:
-------------------------------------------------------------

server could not be registered:
Server response:

my apologies in advance if this is not the correct thread

server could not be registered:
Error: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused

I allso got alot of these messages, on my CentOS52 system it looks like not all the open-xchange processes are not terminated if I execute the init.d scripts or I just takes time to terminate. then a kill -9 comes handy

remove localhost from the line starting with your machines ip address in /etc/hosts and add a new line

Code:

127.0.0.1       localhost

to /etc/hosts

lost in translation

I have been trying to troubleshoot this same issue, but I'm using the google translation and I think I'm missing something:

Code:

#java -version
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b02)
Java HotSpot(TM) Client VM (build 1.5.0_16-b02, mixed mode, sharing)

#javac -version
javac 1.5.0_16
javac: no source files

# update-alternatives --config java

There are 2 alternatives which provide `java'.

  Selection    Alternative
-----------------------------------------------
*         1    /usr/lib/jvm/java-1.5.0-sun/jre/bin/java
+        2    /usr/lib/jvm/java-6-sun/jre/bin/java

# update-alternatives --config javac

There is only 1 program which provides javac
(/usr/lib/jvm/java-1.5.0-sun/bin/javac). Nothing to configure.

Code:

$ sudo /etc/init.d/open-xchange-admin startStarting Open-Xchange Admin Daemon: open-xchange-admin

ich habe einfach "nur" ein dpkg -i *.deb gemacht.
das lief so schnell durch, dass mir fehlende pakete einfach nicht aufgefallen sind.

Hi,

was steht den in folgendem logfile drin:

die fehler kommen bei listcontext und/oder listuser auch, also bei eigentlich fast allen tools. initconfigdb und oxinstaller liefen fehlerfrei durch.

Wenn der admindaemon neugestartet wird, steht normalerweise im logfile so etwas wie:

INFO: Admindaemon successfully started!

Kommt diese Nachricht nach einem Admindaemon neustart? Ausserdem sollte auch die JMX Url im log erscheinen wenn der Daemon erfolgreich neugestartet wurde.
