After installing nagios, browsing the nagios web page, i got the following error:

Could not read object configuration data!

Nagios log messages didn’t reported any useful information. So googling around and making some test i discovered that was a permission problem of the nagios cache files. So i solved my problem changing the group of the /var/cache/nagios3/ directory as follow:

chgrp -R apache /var/cache/nagios3/

Previously was set to www-data .

Enjoy!

Install openkm in /opt directory

Database Setup

DROP DATABASE IF EXISTS okm_repo; DROP DATABASE IF EXISTS okm_app;
CREATE DATABASE okm_repo DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_bin;
CREATE DATABASE okm_app DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_bin;
CREATE USER 'openkm'@'localhost' IDENTIFIED BY 'h3ll0$';
GRANT ALL ON okm_repo.* TO 'openkm'@'localhost' WITH GRANT OPTION;
GRANT ALL ON okm_app.* TO 'openkm'@'localhost' WITH GRANT OPTION;

Configure Datasource

Edit the file $JBOSS_HOME/server/default/deploy/openkm-ds.xml as follow:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<local-tx-datasource> 
	<jndi-name>OpenKMDS</jndi-name> 
	<connection-url>jdbc:mysql://localhost:3306/okm_app?autoReconnect=true</connection-url> 
	<driver-class>com.mysql.jdbc.Driver</driver-class> 
	<user-name>openkm</user-name> 
	<password>h3ll0$</password> 
	<min-pool-size>5</min-pool-size> 
	<max-pool-size>20</max-pool-size> 
	<idle-timeout-minutes>28680</idle-timeout-minutes> 
	<exception-sorter-class-name>com.mysql.jdbc.integration.jboss.ExtendedMysqlExceptionSorter</exception-sorter-class-name>
	<valid-connection-checker-class-name>com.mysql.jdbc.integration.jboss.MysqlValidConnectionChecker</valid-connection-checker-class-name>
	<metadata> <type-mapping>mySQL</type-mapping></metadata> 
</local-tx-datasource>
</datasources>

Configure repository.xml

Replace the $JBOSS_HOME/repository.xml with this one.

I changed the <PersistenceManager> block inside both <Workspace> and <Versioning> blocks as follows:

<Workspace name="${wsp.name}">
....
<PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.MySqlPersistenceManager">
  <param name="driver" value="com.mysql.jdbc.Driver"/> 
  <param name="url" value="jdbc:mysql://localhost:3306/okm_repo?autoReconnect=true"/> <param name="schema" value="mysql"/>
  <param name="user" value="openkm"/>
  <param name="password" value="h3ll0$"/>
  <param name="schemaObjectPrefix" value="${wsp.name}_"/>
  <param name="externalBLOBs" value="false"/> 
</PersistenceManager>
....
</Workspace>
<Versioning rootPath="${rep.home}/version">
...
<PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.MySqlPersistenceManager">
  <param name="driver" value="com.mysql.jdbc.Driver"/>
  <param name="url" value="jdbc:mysql://localhost:3306/okm_repo? autoReconnect=true"/>
  <param name="schema" value="mysql"/> 
  <param name="user" value="openkm"/> 
  <param name="password" value="h3ll0$"/> 
  <param name="schemaObjectPrefix" value="version_"/> 
  <param name="externalBLOBs" value="false"/>
</PersistenceManager>
...

Setup OpenKM.cfg

Edit the $JBOSS_HOME/OpenKM.cfg as follows:

hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl=create

Run OpenKM

Next you can run OpenKM with

$JBOSS_HOME/bin/run.sh

To listen on all network interfaces run with the -b 0.0.0.0 option.
Once you run the server for the first time remember to change the hibernate.hbm2ddl option to none in the OpenKM.cfg. This will avoid to recreate the tables each time you run the server.

Enjoy!

The solution is to install the ruby-dev package:

lorenzo@ubuntu:~$ sudo apt-get install ruby-dev

So i wrote an utility script which create for you these two files with some convenient functions. You can download the script Here!

To run the script just give the right permissions and type ./solaris_home.sh

That’s all! If you already have yours .bash_profile and .vimrc, then they’ll backed up with the extention .bak

Try it now and I hope that you’ll be happy!

1. Verify that the directory structure is correct (the directories VIDEO_TS and AUDIO_TS must exists in the DVD root directory)
2. Make the iso image with genisoimage (or mkisofs) as follows:

genisoimage -dvd-video -udf -V "Volume Name" -o  volume.iso "DVD_Dir"

ssh -D 8080 -f -C -q -N lorenzo@www.myserver.com

You will then be prompted for your password, which you should enter. That’s it! Your ssh tunnel is in place!

A quick synopsis of what those switches mean is as follows:

-D 8080 : This basically does a lot of dynamic stuff and makes it behave as a SOCKS server. Of course you could use any non privileged port here (above 1023).

-f : This will fork the process into the background after you type your password.

-C : Turns on compression.

-q : Quiet mode. Since this is just a tunnel we can make it quiet.

-N : Tells it no commands will be sent. (the -f will complain if we don’t specify this).
