CLI to upload image to openstack cloud

April 18th, 2012 by

I work on automatic testing of one of our products that creates other projects.
And because there is a lot of clouds everywhere I want to use them too. We
have internally an OpenStack cloud (still Diablo release). So I need to solve
automatic uploading of images built in the Build Service. Below I describe my working version.

new package postgresql-plr. Get the power of R inside your postgreSQL database

March 30th, 2012 by

I’m pleased to introduce you to a new available package for postgreSQL database.
The R procedural language extension developed by Joseph E Conway.

R Procedural Language for PostgreSQL

Introduction

PL/R is a library which allow you to add the power of R statistical engine in your database.
This article will show you how to add it and basic usage on a 12.1 installation.
(The package is also available for 11.4)

Become familiar with the project and how it can help you.
The homepage project : www.joeconway.com/plr/

new package squidview available

July 17th, 2011 by

squidview

squidview is one of the software, I’ve always build and installed on each squid proxy server I build for me or customers. It’s small, stable, and usefull. So it was a clear real nice candidate to be use to improve my obs and packager skiil.
I would like to thanks T1loc, yaloki, mrdocs, coolo, alin, and all others great packagers around, for helping and teaching me during the process.

Introduction

Squidview is an interactive console program which monitors and displays squid logs in a nice fashion, and may then go deeper with searching and reporting functions.

(If you don’t know what squid is or does this program is probably not for you.)

To use squidview you must at least have read access to squid’s access.log file. You may need to see your administrator for this. Squidview uses this text log file for all operations. It does not generate its own database for tasks.

homepage www.rillion.net/squidview

Features

Squidview has a number of functions. Navigate the log file with the cursor pad keys, jump to a certain day or switch to a different log file. Search for text or large http/ftp requests.

Put squidview into monitor mode: see the latest activity updated every 3 seconds (this is light on cpu load).

Reports can be generated listing the heavist Internet users and the most popular visited sites. See how many cache hits squid makes to save network traffic.

Squidview is released under the GPL.

Examples / Usage

What the above would be if viewed with less.

A tally of all users against the bandwidth they used. Kept current in near real time.

A quick investigation into the recent history of one user.

Installation / Repositories

I’ve just made a submit request against openSUSE_Factory to get it included directly, but in the meantime, you could install it from the repository server:proxy as many other useful & related packages

For example adding the repository under openSUSE_Factory

zypper ar -c -f -n "server:proxy" http://download.opensuse.org/repositories/server:/proxy/openSUSE_Factory "server:proxy"
zypper in squidview

Builds available for :

The package is build successfully against : SLES10, SLES11, openSUSE 11.3 to Factory

Have Fun!

1-2-3 Cloud

June 20th, 2011 by

Towards the end of last year there was an article in openSUSE news “announcing” the cloud efforts in the openSUSE project and on OBS. Well, cloud is still all the rage (see Jos’ contribution to openSUSE News issue 180) and people just cannot stop talking about cloud computing.

Using openSUSE as a host for your cloud infrastructure is also making great progress. We have 3 cloud projects in OBS and hopefully these cover your favorite cloud infrastructure code, Virtualization:Cloud:Eucalyptus, Virtualization:Cloud:OpenNebula, and Virtualization:Cloud:OpenStack. The projects provide repositories for Eucalyptus, OpenNebula, and OpenStack, respectively.

We attempt to make it relatively easy to get a cloud up and running. In this process OpenNebula and OpenStack have progressed the most. Eucalyptus is working, but due to an issue with Eucalyptus and openSSL 1.0 and later (the version in openSUSE) automation has to wait until these issues are resolved.

For OpenNebula we now have a KIWI example that shows how one can get a cloud setup from scratch in less than 2 hours, including the image build. The example contains a firstboot workflow for the head node, and self configuration of cloud nodes.

For OpenStack SUSE Gallery images are in the works and will be published in the near future.

All repositories provide packages you can install on running openSUSE systems. If you are interested in using openSUSE as the underlying OS for your cloud or if you want to contribute to the cloud projects, subscribe to the cloud mailing list opensuse-cloud@opensuse.org

Oxygenise your Apache

January 24th, 2011 by

I have updated apache2-icons-oxygen with icons from KDE 4.6 RC2. Thanks Nuno & Co! Now Apache’s directory listings look a bit better ;-)

See it in action here. If you want to download the tarball/rpm, go to the Build Service.

Make vmware workstation 7.1.3 running with opensuse 11.4 (kernel 2.6.37)

November 15th, 2010 by

Note about the 2.6.37xx

There’s a solution to make the kernel modules building under openSUSE factory (11.4) and the kernel 2.6.37

Preparation

download the lastest vmware workstation 7.1.3 (the patch is only for this version)
download the patch vmware-7.1.3-2.6.37-rc5.patch
download the script to patch patch-modules_v62-opensuse.sh

Install

Proceed to the normal installation of workstation, if you have older version, it will be replaced
by running under root account

sh VMware-Workstation-Full-7.1.3-324285.x86_64.bundle

Patch

Now we have to apply the needed patch, just run as root

sh patch-modules_v62-opensuse.sh

Here the output result

sh patch-modules_v62-opensuse.sh 
(Stripping trailing CRs from patch.)

OPENSUSE 11.3/SLES 11 ** INTEGRATING FREERADIUS TO LDAP SERVER

November 12th, 2010 by

FreeRADIUS is a modular, high performance free RADIUS suite developed and distributed under the GNU General Public License, version 2, and is free for download and use. The FreeRADIUS Suite includes a RADIUS server, a BSD-licensed RADIUS client library, a PAM library, anApache module, and numerous additional RADIUS related utilities and development libraries (wikipedia)

Remote Authentication Dial In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for computers to connect and use a network service. RADIUS was developed by Livingston Enterprises, Inc., in 1991 as an access server authentication and accounting protocol and later brought into the Internet Engineering Task Force (IETF) standards(wikipedia)

Well, then again a bit of introduction about “what is RADIUS ?” and the FreeRADIUS, the most popular OpenSource RADIUS Server :D.

This tutorial based on an existing LDAP Server Configuration ( you can read this post) and it already has 1-2 users on it ( you can read this post again :) ),  and this post is explain how-to integrate FreeRADIUS to read and use existing user on LDAP Server.

you can install the FreeRadius server on the same server or on a seperate server ( it’s your choice :p )

  • Add the FreeRADIUS repository from software.opensuse.org
# zypper ar http://download.opensuse.org/repositories/network:/aaa/SLE_11/ FreeRadius
# zypper ref
  • Install the FreeRADIUS Server Package
# zypper in freeradius-server freeradius-client freeradius-server-utils
  • After Installing the FreeRADIUS Packages, edit /etc/raddb/modules/ldap file, and then find and edit following lines (in my case : dc=malayin,dc=net) :
ldap {

server = “192.168.0.30″ the LDAP Server
#identity = “cn=Adminstrator,dc=malayin,dc=net”
#password = admin
basedn = “dc=malayin,dc=net” – The Base DN LDAP Server
#filter = “(uid=%{Stripped-User-Name:-%{User-Name}})”
filter = “(uid=%u)”
#base_filter = “(objectclass=radiusprofile)”
ldap_connections_number = 5
timeout = 4
timelimit = 3
net_timeout = 1

tls {
start_tls = no
}
access_attr = “uid”
edir_account_policy_check = yes
}
  • After editing the ldap file, save it and then edit /etc/raddb/sites-available/default. FIND THE LINES that contain LDAP word and uncomment the lines :

authorize {
#
#  The preprocess module takes care of sanitizing some bizarre
#  attributes in the request, and turning them into attributes
#  which are more standard.
#
#  It takes care of processing the ‘raddb/hints’ and the
#  ‘raddb/huntgroups’ files.
#
#  It also adds the %{Client-IP-Address} attribute to the request.
#preprocess
#
#  If you want to have a log of authentication requests,
#  un-comment the following line, and the ‘detail auth_log’
#  section, above.
# auth_log
#
#  The chap module will set ‘Auth-Type := CHAP’ if we are
#  handling a CHAP request and Auth-Type has not already been set
#chap
#
#  If the users are logging in with an MS-CHAP-Challenge
#  attribute for authentication, the mschap module will find
#  the MS-CHAP-Challenge attribute, and add ‘Auth-Type := MS-CHAP’
#  to the request, which will cause the server to then use
#  the mschap module for authentication.
#mschap
#
#  If you have a Cisco SIP server authenticating against
#  FreeRADIUS, uncomment the following line, and the ‘digest’
#  line in the ‘authenticate’ section.
# digest
#
#  Look for IPASS style ‘realm/’, and if not found, look for
#  ‘@realm’, and decide whether or not to proxy, based on
#  that.
# IPASS
#
#  If you are using multiple kinds of realms, you probably
#  want to set “ignore_null = yes” for all of them.
#  Otherwise, when the first style of realm doesn’t match,
#  the other styles won’t be checked.
#
#suffix
# ntdomain
#
#  This module takes care of EAP-MD5, EAP-TLS, and EAP-LEAP
#  authentication.
#
#  It also sets the EAP-Type attribute in the request
#  attribute list to the EAP type from the packet.
#
#  As of 2.0, the EAP module returns “ok” in the authorize stage
#  for TTLS and PEAP.  In 1.x, it never returned “ok” here, so
#  this change is compatible with older configurations.
#
#  The example below uses module failover to avoid querying all
#  of the following modules if the EAP module returns “ok”.
#  Therefore, your LDAP and/or SQL servers will not be queried
#  for the many packets that go back and forth to set up TTLS
#  or PEAP.  The load on those servers will therefore be reduced.
#
#eap {
# ok = return
#}
#
#  Pull crypt’d passwords from /etc/passwd or /etc/shadow,
#  using the system API’s to get the password.  If you want
#  to read /etc/passwd or /etc/shadow directly, see the
#  passwd module in radiusd.conf.
#
#unix
#
#  Read the ‘users’ file
#files
#
#  Look in an SQL database.  The schema of the database
#  is meant to mirror the “users” file.
#
#  See “Authorization Queries” in sql.conf
# sql
#
#  If you are using /etc/smbpasswd, and are also doing
#  mschap authentication, the un-comment this line, and
#  configure the ‘etc_smbpasswd’ module, above.
# etc_smbpasswd
#
#  The ldap module will set Auth-Type to LDAP if it has not
#  already been set
ldap
#
#  Enforce daily limits on time spent logged in.
# daily
#
# Use the checkval module
# checkval
expiration
logintime
#
#  If no other module has claimed responsibility for
#  authentication, then try to use PAP.  This allows the
#  other modules listed above to add a “known good” password
#  to the request, and to do nothing else.  The PAP module
#  will then see that password, and use it to do PAP
#  authentication.

#  Authentication.
#
#
#  This section lists which modules are available for authentication.
#  Note that it does NOT mean ‘try each module in order’.  It means
#  that a module from the ‘authorize’ section adds a configuration
#  attribute ‘Auth-Type := FOO’.  That authentication type is then
#  used to pick the apropriate module from the list below.
#
#  In general, you SHOULD NOT set the Auth-Type attribute.  The server
#  will figure it out on its own, and will do the right thing.  The
#  most common side effect of erroneously setting the Auth-Type
#  attribute is that one authentication method will work, but the
#  others will not.
#
#  The common reasons to set the Auth-Type attribute by hand
#  is to either forcibly reject the user (Auth-Type := Reject),
#  or to or forcibly accept the user (Auth-Type := Accept).
#
#  Note that Auth-Type := Accept will NOT work with EAP.
#
#  Please do not put “unlang” configurations into the “authenticate”
#  section.  Put them in the “post-auth” section instead.  That’s what
#  the post-auth section is for.

  • save the file, then add these line to /etc/raddb/clients.conf filem to decide which network is ALLOWED to use and access FreeRADIUS service (in my case : 192.168.0.0/24)  :

client 192.168.0.0/24 {

secret = testing123-1

shortname = testing123-1

}

  • After finish editing clients.conf file, save it and then test the connectivity by using radtest command

Merging SVN Repositories Explained

October 30th, 2010 by

Adding files to a SVN server is usually a task done in seconds. However, having several independent SVN repositories and wanting to “combine” them, this is not trivial—especially if you want to preserve the history.

The doc team had had three different, independent repositories on BerliOS (opensuse-ha-doc, opensuse-docmaker, and opensuse-lfl) all holding separate information. This was a bit silly, so my task was to consolidate them into opensuse-doc by keeping all history.

OBS 2.1: Status of SuperH (sh4) support with QEMU

October 24th, 2010 by

With established ARM support in OBS the as well as emulated MIPS and PowerPC is getting more mature, the last big embedded architecture not working in OBS with QEMU user mode was SH4. QEMU developers community had done a lot of work in improving QEMU user mode during the last months, so I can proudly present with currently only a few patches to QEMU git master OBS builds working with the SH4 port of Debian Sid. The new QEMU 0.13 released recently is a big milestone for this.

Another news is that I had fixed the bugs in Virtual Machine builds (build script) when using them with some architectures like PowerPC 32bit and SH4. So now also the combination of using for example KVM (XEN should also work) in a worker together with ARM, MIPS, PowerPC and SH4 is working. The appropriate fixes are in one of the next build script releases (if not even released already now with OBS 2.1, I have to check that). You can select architecture “sh4″ with OBS 2.1 and also start a scheduler with “sh4″.

With the use of the QEMU User Mode, you can build also accelerated native cross toolchains for your host architecture so time critical parts like the compiler can run without the emulator. This works with .deb as well as with .rpm based backages. The MeeGo Project as well as the openSUSE Port to ARM uses this technique to provide an optimum between compatibility and performance. It means you can mix natively build packages and use cross toolchains on it. The “CBinstall:” feature helps you to use native or cross builds automatically depending on if your build host is a native machine or a x86 machine with cross build. In summary, we have the current classics of linux embedded archs together now in OBS: ARM, x86, MIPS 32, PowerPC 32 and SH4.

I have uploaded the fixed QEMU package to the OBS project openSUSE:Tools:Unstable inside the package “qemu-devel” after some more testing. I have of course also a OBS meta prjconf file working with Debian Sid. The SH4 port of Debian Sid you can find at Debian Ports Site.

And last but not least I would like to thank Riku Voipio of the Debian Project, QEMU project and MeeGo project and other major contributors during the QEMU 0.13 development cycle for the restless work on QEMU user mode improvements. In case of KVM, QEMU is used even twice, with QEMU-KVM as well as QEMU User Mode. I am sure I had forgotten other important people, so thanks to them also.
