Download Ubuntu 11.10 (Oneiric Ocelot) CD ISO / DVD Images

Ubuntu Linux (a GNU/Linux-based computer operating system) version 11.10 has been released and available for download. The new release includes some enhancements to make your experience even more enjoyable. The Default user interface is set to unity shell on top of GNOME 3.x. However, you will get a 2D version of Unity as a fallback for systems that lack the hardware resources for the 3D version. The good news is you will be able to install the entire GNOME 3 desktop along with GNOME Shell directly from the Ubuntu repos.

Installing LedgerSMB 1.3 Series (Open Source Accounting/ERP Application) On Ubuntu 11.10 (Oneiric Ocelot)

localhost.

This tutorial is only for LedgerSMB 1.3 series.

For the 1.2 versions please refer to http://www.howtoforge.com/ledgersmb_debian_etch of which author is Falko Timme: Installing LedgerSMB (Open Source Accounting Application) on Debian Etch.

Only with this remark that libmd5-perl is not in the repositories anymore. Hereunder you will find how to download and install this Perl-module.

Thanks to Falko I could explore LedgerSMB in the beginning. Evidently I would like to thank also Chris Travers (www.ledgersmb.org) who has assisted me a lot.

Of course there is no guarantee that this will work in general terms.

This instruction is made with the intention that you can copy and paste the commands into the terminal. In case of sudo commands your password will be asked.

The same goes for the needed changes in some configuration files; evidently the changes in those files have to be done manually.

 

2. Installation Of Required Perl Modules And Required Texlive Modulessudo apt-get install libdata-dumper-simple-perl perl-modules liblocale-maketext-lexicon-perl libdbi-perl libdbd-pg-perl libconfig-any-perl libmime-lite-perl libhtml-linkextractor-perl libnet-tclink-perl libparse-recdescent-perl libmodule-build-perl libperl5.12 libuuid-perl liblocale-gettext-perl libyaml-tiny-perl libtext-iconv-perl libtext-charwidth-perl libmodule-install-perl liblatex-driver-perl

(This is one command.)

There are another three modules to be installed, the first two (SOURCE: Falko Timme):

libclass-std-perl
libconfig-std-perl

But they are not in the repositories. First both should be done by downloading from Sourceforge:

cd /tmp
wget http://mesh.dl.sourceforge.net/sourceforge/ledger-smb/deb-prereq-1.2.8.tar.gz
tar xvfz deb-prereq-1.2.8.tar.gz
cd deb-prereq-1.2
sudo dpkg -i libclass-std-perl_0.0.8-1_all.deb libconfig-std-perl_0.0.4-1_all.deb

The last one is:

libmd5-perl

This is to be downloaded from Debian:

cd /tmp
wget http://ftp.debian.org/pool/main/libm/libmd5-perl/libmd5-perl_2.03-1_all.deb
sudo dpkg -i libmd5-perl_2.03-1_all.deb

In connection with the above mentioned installed Perl modules a few texlive modules should be installed also. I would like to emphasize if those are not installed Perl will not work with the LedgerSMB!!!

sudo apt-get install texlive-fonts-extra texlive-latex-extra-doc texlive-lang-all texlive-latex-extra texlive-fonts-recommended texlive texlive-doc-en

This could take long time (700MB)!!!

Unfortunately one needed Texlive-module is not in the repositories:

texlive-generetic-extra

This is going to be downloaded from Ubuntu: http://packages.ubuntu.com/lucid/texlive-generic-extra

Just copy and paste this in your browser in order to enter this website. Under the page you will see this: "Download texlive-generic-extra" and go to
"all" under "architecture", then choose a "site" (a lot) for download and choose save.

In order to install this do the following:

cd

Debian / Ubuntu Linux: Configure Network Bonding [ Teaming / Aggregating NIC ]

NIC teaming is nothing but combining or aggregating multiple network connections in parallel. This is done to increase throughput, and to provide redundancy in case one of the links fails or Ethernet card fails. The Linux kernel comes with the bounding driver for aggregating multiple network interfaces into a single logical interface called bond0. In this tutorial, I will explain how to setup bonding under Debian Linux server to aggregate multiple Ethernet devices into a single link, to get higher data rates and link failover.

Prevent Ubuntu from asking a password after resuming from Hibernate or Suspend

When you close the lid of your laptop and Ubuntu is running, the computer goes into Suspend mode. Same goes for chosing Hibernate from the shutdown menu, when the laptop goes into deep sleep and consumes less power. When resuming from these two states, Ubuntu will ask you for your password. If you’d like to get rid of this password field, you need to launch gconf-editor and navigate to apps > gnome-power-manager > lock. There you’ll find a checkbox for hibernate and one for suspend. Uncheck these and close the Configuration Editor. Next time you resume from Suspend and Hibernate, you won’t be prompted for a password.
You can still manually lock your screen before closing the lid by using Ctrl

How To Install OpenERP 6 On Ubuntu 10.04 LTS Server

sudo apt-get install openssh-server denyhosts

Now make sure you are running all the latest patches by doing an update:

sudo apt-get update
sudo apt-get dist-upgrade

Although not always essential it’s probably a good idea to reboot your server now and make sure it all comes back up and you can still login via ssh.

Now we’re ready to start the OpenERP install.

 

Step 2. Create the OpenERP user that will own and run the application sudo adduser --system --home

How To Set Up And Integrate An Ubuntu 10.04 LTSPv5 Server Into A Windows 2008 Active Directory Domain

(JavaScript must be enabled in your browser to view the large image as an image overlay.)

dc.domain.internal

Windows 2008 Server running Active Directory and DNS

server.domain.internal

Windows 2003 Server hosting user home directories and file shares

thinserver.domain.internal

Ubuntu 10.04.2 server with LTSPv5

dhcp.domain.internal

CentOS 5.0 server running dhcpd

 

Ubuntu LTSP Installation

To install Ubuntu with LTSP, follow the instructions here.

If your server has more than 4 GB of RAM, make sure you install the Linux PAE Kernel.

sudo apt-get install linux-generic-pae linux-headers-generic-pae

 

Add thinserver to the Windows Domain

Before we add thinserver to the domain, we're going to have to install Samba along with some other packages.

sudo apt-get install samba smbclient winbind libpam-cracklib krb5-user

Make sure that thinserver is named correctly.

hostname

If the hostname command doesn't return thinserver.domain.internal, rename it to thinserver.domain.internal.

hostname thinserver.domain.internal

Edit the /etc/resolv.conf to use dc.domain.internal as the primary DNS server.

search domain.internalnameserver 10.0.0.10

On your domain controller create a host (A) record in your DNS for thinserver.

Verify that thinserver can resolve domain.internal:

nslookup domain.internal

The results should look something like this:

Securing OpenVPN With A One Time Password (OTP) On Ubuntu

"-lpam"

Save the file and lets proceed, shall we?We need to compile this, so thats easy:

make

No errors? Good. It might be that you get an error about "displayQRCode". If so, you will need to make some changes to the makefile. If everything went as it should, you can just proceed.

find /usr/lib -name libdl.so

In the makefile, replace all 3 references to "/usr/lib/libdl.so" with the path you got (e.g. "/usr/lib/i386-linux-gnu/libdl.so").Save it up, and re-run make. You should now be able to proceed just fine.

If it was compiled succesfully, proceed with installing it: make install

We're done, let's proceed shall we?

 

Configuring OpenVPN to use PAM

Open up /etc/openvpn/server.conf and add the following line:

plugin /usr/lib/openvpn/openvpn-auth-pam.so openvpn

This will use PAM to provide additional means of authentication.The last part (openvpn) is the file in /etc/pam.d we'd like to use. Since we do not want it to interfere with other services (e.g. SSH or sudo) we just use a new file.

Restart OpenVPN to have it re-read the config file.

 

Configure PAM to authenticate using Google Authenticator

Create the file /etc/pam.d/openvpn:

cp /etc/pam.d/common-account /etc/pam.d/openvpn
vim /etc/pam.d/openvpn

Add the following line:

auth required pam_google_authenticator.so

If you are using encrypted homedirectories, you will need to change that to:

auth required pam_google_authenticator.so secret

Synaptic Removed From Ubuntu Linux v11.10

Synaptic is a front-end for the apt package management system. The program allows you to perform all actions of the command line tool apt-get in a graphical environment such as installing, upgrading, downgrading and removing of single packages or even upgrading your whole system. The upcoming Ubuntu Linux version 11.10 (code named Oneiric Ocelot) has removed Synaptic Package Manager.

To be frank, I never used Synaptic or so called the Software Center. I use apt-get all the time to install, remove, and update the system or apt-cache to search required packages. Synaptic is fine tool and I'm not sure why Canonical decided to remove the same. Canonical is making lots of new decisions and no one in the enterprise environment like new changes.

How Do I Install Synaptic?

Ubuntu Linux: Install RT2870 Chipset Based USB Wireless Adapter

This blog post listed Linux Compatible USB wireless adapters. It seems that many new Linux users frequently have problems learning how to install RT2870 driver under Linux. I also received email requesting installation instructions for the same device. This quick tutorial will explains how to install RT2870 based chipset device with WPA2 authentication and TKIP wireless encryption.

Our Sample Setup

The following instructions are tested on:

Ubuntu Linux 10.04.1 LTSKernel - Linux 2.6.32-24-generic-pae i686 (32 bit)WPA2 with Linksys 160N router RT2870 Chipset Based Devices Are Not Working Out Of Box

The main problem is conflicting driver which are shipped with default kernel. WPA2 is a method of security wireless networking with optional PSK for home users. The default driver only recognizes driver but always failed to join WPA2 based network. The solution is to install RT2870 driver from the vendor site.

Step #1: Disable Default Drivers

Type the following command to black list default drivers:
$ sudo vi /etc/modprobe.d/blacklist.conf
Append the following driver names:

blacklist rt2800usbblacklist rt2x00libblacklist rt2x00usb

Save and close the file. Use the rmmod command to remove current drivers or just reboot the system:
$ sudo modprobe -r driverName
# you need to remove all of the above drivers one by one:
$ sudo modprobe -r rt2800usb
OR simply reboot the systems:
$ sudo reboot

Step 2: Install Compilers

Type the following command to install required packages so that you can compile source code:
$ sudo apt-get install build-essential fakeroot dpkg-dev
Finally, install Linux kernel headers so that you can compile kernel device drivers:
$ sudo apt-get install linux-headers-$(uname -r)

Step #3: Download Driver
