Installing Ricoh Aficio SG3100SNw in linux

So , you have decided to purchase a Ricoh Aficio SG3100SNw printer. Good. It’s a good choice for small / medium companies. What we like about it is that it comes with wireless interface and that is quite nice . Less cables more fun. I’m not going to get into details on how to unbox it and make the initial setup. I leave that as an exercise for the reader ( it’s not easy but up to a point it’s fun ) .   Continue reading Installing Ricoh Aficio SG3100SNw in linux

Ubuntu 14.04 adding HP proliant support pack (hpacucli problem solved)

tfm_logoIn the begining there was nothing but few baremetal. After a while someone delivers a whole bunch of baremetal on your doorstep and say : “I need them installed by tomorrow”. Same configuration … With the harddisks in raid and ubuntu on all of them . What do you do ?

It’s a big problem. Like most big problems you split it in lots of little problems that can be managed easier.
What you need to do for one baremetal:

  1. Update the ILO firmware and Bios (if necessary) . This will come handy: . I’m not going into details about it in this post
  2. Create the disk arrays
  3. Install the operating system on it
  4.  Configure it and deploy it.

For one server let’s say you can do it in few hours , few beers and some pizza’s. But … wait a minute .. There are a LOT of baremetals to be installed. One option is to call some friends and do that while you watch a movie.

OR you can be smart and automate the tasks. How ? What i need ?

You need a baremetal installer server or a laptop or a virtual something (virtual box / vmware / you choose )  image that will do the job for you while you sit back and relax.

The ideea is simple:

  • Baremetal will boot from network
  • tftp server will deliver the boot image, boot it , get an ip addres from the dhcp server and register the new server into the baremetal installer and will fill the hardware configuration there.
  • Then you can ( using ansible  ) to actually do the raid configuration ,  bios updates ,  firmware updates, and operating system install.
  • Add the necessary configurations.
  • Once complete the system will boot from raid and you have a system up and and running ready to be deployed.

Now … Back to the post subject .

How you can configure HP raid from inside  ubuntu ? In order to have in the network bootable image the proper tools to do actually do the configurations…

First we install hpacucli :

sudo echo "deb precise/current non-free" >>/etc/apt/sources.list
sudo apt-key add GPG-KEY-mcp
sudo apt-get update
apt-get install cpqacuxe hp-ams hp-health hpacucli hponcfg
service hpsmhd stop
update-rc.d hpsmhd disable
hpasmcli -s "show server"

Then when we boot the new baremetal to be installed we can gather the informations about the raids:

hpacucli ctrl all show config

That will produce an output like ( in this case i already configured the raid:

Smart Array E200i in Slot 0 (Embedded) (sn: VX9AMP1927 )

array A (SAS, Unused Space: 0 MB)

logicaldrive 1 (136.7 GB, RAID 1, OK)

physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 146 GB, OK)
physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 146 GB, OK)

At this point you can create some scripts that will create the partitions in the way that the shareholder wants them.

for example:

hpacucli ctrl slot=9 create type=logicaldrive drives=1I:1:3,1I:1:4 raid=1

Searching for Central Authentication Service

We are  searching for CAS (Central Authentication Service) for a project .

The Central Authentication Service (CAS) is a single sign-on protocol for the web. Its purpose is to permit a user to access multiple applications while providing their credentials (such as userid and password) only once. It also allows web applications to authenticate users without gaining access to a user’s security credentials, such as a password

We are evaluating CAS solution from:

In this post I’ll try to explain how to get jasig CAS up and running.I’m assuming that all CAS related programs will be in /opt/CAS , if you need them in other location you will have to slightly adjust the paths.

To get it up and running you will need:

    • Apache maven ( I used version 3.0.5 ( latest at the time of the post writing ) . Instalation of apache maven is straight forward .
mkdir -p /opt/CAS
cd /opt/CAS
tar xf apache-maven-3.0.5-bin.tar.gz
export PATH=$PATH:/opt/CAS/apache-maven-3.0.5/bin
cd /opt/CAS
tar xf apache-tomcat-7.0.41.tar.gz
cd /opt/CAS
tar xf cas-server-3.5.2-release.tar.gz
cd /opt/CAS
tar xf mysql-connector-java-5.1.25.tar.gz

Now we have everything we need for the build. Let’s start configure it

Edit the file: cas-server-3.5.2/cas-server-webapp/pom.xml

And change commons-dbcp version from 1.2.2 to 1.4 . Otherwise the CAS will give some obscure null errors after startup. After athat add the following:


Edit the file cas-server-3.5.2/cas-server-webapp/target/cas-server-webapp-3.5.2/WEB-INF/deployerConfigContext.xml and add the following ( required for mysql support and changed default demo authentication to mysql auth)

<!--                <bean
 class="" />
<bean class="org.jasig.cas.adaptors.jdbc.SearchModeSearchDatabaseAuthenticationHandler">
 <property  name="tableUsers">
 <property name="fieldUser">
 <property name="fieldPassword">
 <property name="passwordEncoder">
 <bean class="org.jasig.cas.authentication.handler.DefaultPasswordEncoder">
 <constructor-arg value="MD5" />
 <property name="dataSource" ref="dataSource" />

And at the end of file before /beans add the mysql configuration:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
 <property name="driverClassName">
 <property name="url">
 <value>jdbc:mysql://localhost:3306/cas</value> <!-- Replace this line with the database containing the users table -->
 <property name="username">
 <value>REPLACE_ME</value> <!-- Replace this line with the MySQL username -->
 <property name="password">
 <value>REPLACE_ME</value> <!-- Replace this line with the actual MySQL password -->

On your mysql server create the database and table where the users will be kept and insert a test user :

create database cas;
 grant all on cas.* to REPLACE_ME@ identified by 'REPLACE_ME';
 CREATE TABLE users (username char(20) PRIMARY KEY NOT NULL, password char(64));
 INSERT INTO users(username, password) VALUES ('Test44',MD5('passTest'));

Now the building part:

1. First install mysql connector

mvn install:install-file -DgroupId=mysql -DartifactId=mysql-connector-java -Dversion=5.1.25-bin -Dpackaging=jar -Dfile=../../mysql-connector-java-5.1.25/mysql-connector-java-5.1.25-bin.jar

2. Next build the war file

mvn package install

Install the package into tomcat directoy:

cp cas-server-3.5.2/cas-server-webapp/target/cas.war /opt/CAS/apache-tomcat-7.0.41/webapps

And after this restart your tomcat and point a browser to http://localhost:8080/cas  and you should have a CAS instance up and running.

Things to test from this point forward:

  1. Test custom table structure
  2. Configure tomcat for SSL
  3. How to add custom password encryption
  4. How to add custom SQL auth string
  5. Attribute releasing from database
  6. Integration with a website
  7. Facebook login , oAuth login
