Run multiple versions of Perl from your home directory

Jason L Froebe — Tue, 23 Nov 2010 04:07:46 +0000

Run multiple versions of Perl from your home directory using Perlbrew!

One thing to know: Perl won’t compile if you have an encrypted home directory. Bug has been fixed but not exactly how and it hasn’t been put into the Ubuntu updates yet.

Thanks goes to Kang-min Liu for creating Perlbrew!!!!

The recommended way to install perlbrew is to run these statements in your shell:

curl -LO http://xrl.us/perlbrew
chmod +x perlbrew
./perlbrew install

After that, perlbrew installs itself to ~/perl5/perlbrew/bin, and you should follow the instruction on screen to setup your .bashrc or .cshrc to put it in your PATH.

High overview of Cloud Computing with Ubuntu Eucalyptus Cloud (UEC) from Canonical

Jason L Froebe — Tue, 22 Jun 2010 12:52:15 +0000

I installed Ubuntu Eucalyptus cloud (#UEC) on a couple of servers at home. I was naively expecting it to be similar to VMware. Oh I was wrong.

UEC is the Eucalyptus ‘cloud’ software running on Ubuntu servers. The instances would run under the KVM or Xen hypervisors. Ubuntu’s defaulted to running KVM but isn’t restricted by it.

“Eucalyptus is a software available under GPL that helps in creating and managing a private or even a publicly accessible cloud. It provides an EC2 compatible cloud computing platform and S3 compatible cloud storage platform…” Eucalyptus Beginner’s Guide

This is how a vm works in UEC:

You publish an image that you previously installed all the software you need (or you can download such an image). There can be as many instances of this image running as the hardware supports (spread across N number of backend Node Servers).

All instances are transient. As long as an image is running, it will have a physical presence.. but when it is shutdown, the instance is removed including any work performed in the instance.

“static” storage is available via a Storage Server. After you create an image but before you start it, you have the opportunity to attach storage to the instance.

While the management tools for UEC, and therefore Amazon EC2/EM, are primitive compared to VMware, it should be able to scale much higher with far less focus on which ‘virtual machine’ goes where.

How to: Installing VMware ESXi 4 on a 6 year old cheap motherboard

Jason L Froebe — Mon, 15 Feb 2010 14:59:17 +0000

I’ve been trying to get VMware ESXi 4 on my old MSI MS-7388 motherboard for a long time. No matter what I tried, neither the SATA controller on the motherboard or the add on SATA controller would be recognized.

Install VMware ESXi 4.0 on an unsupported motherboard (SATA controller must support AHCI):

make sure the SATA controller(s) is set to AHCI in the computer’s BIOS
download VMware ESXi 4 iso
burn the iso to either a cdrom or a USB thumb drive (512mb minimum) using unetbootin
boot the computer into VMware ESXi
Before you’re prompted to hit Enter to begin, hit ALT-F1 which will get you to a console screen without a prompt
Type “unsupported” followed by Enter
When prompted for a password, just hit Enter
Type “vmkload_mod ahci” followed by Enter. This will load in the driver for just about any AHCI compliant SATA controller
Hit ALT-F2 to finish the installation

At this point VMware ESXi 4.0 will be installed but it won’t start when you reboot. This is because VMware won’t load the AHCI driver by default. So… we will have to tell it to load it automatically. You will need a Linux Live CD such as Ubuntu.

Boot into Linux
From the desktop you will need to mount the VMware partitions. In Ubuntu 8.04 and higher, you just need to click on the folders in the drop down menu
Locate oem.tgz on the second VMware partition and overwrite it with this oem.tgz. It includes a system.map file telling VMware to load the AHCI driver
reboot and boot into VMware ESXi

You should have a fully working VMware ESXi server installed and ready for you to setup virtual machines!

Sun’s VirtualBox 3.1.x: Getting VRDP (remote desktop) to authenticate properly with Linux PAM

Jason L Froebe — Fri, 22 Jan 2010 16:39:55 +0000

I rebuilt an Ubuntu 9.10 server this past week, ripping off VMware and replacing it with VirtualBox 3.1.2. Setting up VirtualBox as a headless server was very easy with VBoxTool. However, I ran into a problem that I was unable to connect using remote desktop (rdesktop) as any user but the user that started the virtual machine.

Jan 21 22:43:13 vm-holder unix_chkpwd[16040]: check pass; user unknown
Jan 21 22:43:13 vm-holder unix_chkpwd[16040]: password check failed for user (jason)
Jan 21 22:43:13 vm-holder VBoxHeadless: pam_unix(vrdpauth:auth): authentication failure; logname=virtualbox uid=1001 euid=1001 tty= ruser= rhost= user=jason

This is, currently, an undocumented security feature of VirtualBox 3.1x to prevent just anyone from accessing the virtual machine console. For most folk, this might be a very good thing but if you have a team of sysadmins that should have access to the virtual machine consoles, you probably don’t want them to use the same login.

If that is the case, you can add the user(s) that should have access the virtual machine console to the shadow group on the host Linux machine. Be warned though that the user(s) that are added to the shadow group should not be able to log into the host machine else they will be able to read the shadow file where all the passwords to the box are stored. If the users need access to the host box, then they should have a login for host access (not part of the shadow group) and another for virtual machine console access.

Adding linux user jason_vrdp to the shadow group:

(root) # usermod -G shadow,virtualbox jason_vrdp

Prevent jason_vrdp from logging in to the host or anyone from sudo’ing to it:

(root) # usermod --shell /bin/false jason_vrdp

That’s it

How to create an iTunes/iPod compatible audiobook (MPEG4 m4b) on Linux using MP4Box and mp4v2 v1.9.1 – it can be done!

Jason L Froebe — Thu, 24 Dec 2009 17:39:18 +0000

I’ve been wracking my brains over this for the past few weeks and it finally struck me how to create an m4b audiobook with chapters that is compatible with your iPod, iTunes, VLC, etc. It was very simple once I figured it out:

Step 1:

encode the mp3 files to “aac” (mpeg4) using your favorite converter (I use ffmpeg):

ffmpeg -i "track1.mp3" -y -vn -acodec libfaac -ab 128k -ar 44100 -threads 3 -f mp4 track1.aac

Step 2:

Create a chapters file so that MP4Box can understand it:

* Common syntax : CHAPTERX=h:m:s[:ms or .ms] on one line and CHAPTERXNAME=name on the other – the order is not important but chapter lines MUST be declared sequencially (same X value expected for 2 consecutive lines).

$ cat track1.chapters
CHAPTER1=00:00:00.000
CHAPTER1NAME=Chapter 001
CHAPTER2=00:30:00.139
CHAPTER2NAME=Chapter 002
CHAPTER3=01:00:00.728
CHAPTER3NAME=Chapter 003
CHAPTER4=01:30:01.269
CHAPTER4NAME=Chapter 004
CHAPTER5=02:00:01.858
CHAPTER5NAME=Chapter 005
CHAPTER6=02:30:02.375
CHAPTER6NAME=Chapter 006
CHAPTER7=03:00:02.964
CHAPTER7NAME=Chapter 007
CHAPTER8=03:30:03.553
CHAPTER8NAME=Chapter 008
CHAPTER9=04:00:04.094
CHAPTER9NAME=Chapter 009
CHAPTER10=04:30:04.683
CHAPTER10NAME=Chapter 010
CHAPTER11=05:00:05.224
CHAPTER11NAME=Chapter 011
CHAPTER12=05:30:05.765
CHAPTER12NAME=Chapter 012
CHAPTER13=05:46:14.106
CHAPTER13NAME=Chapter 013
CHAPTER14=06:16:14.143
CHAPTER14NAME=Chapter 014
CHAPTER15=06:46:14.732
CHAPTER15NAME=Chapter 015
CHAPTER16=07:16:15.249
CHAPTER16NAME=Chapter 016
CHAPTER17=07:46:15.790
CHAPTER17NAME=Chapter 017
CHAPTER18=08:16:16.331
CHAPTER18NAME=Chapter 018
CHAPTER19=08:46:16.920
CHAPTER19NAME=Chapter 019
CHAPTER20=09:16:17.460
CHAPTER20NAME=Chapter 020
CHAPTER21=09:46:18.050
CHAPTER21NAME=Chapter 021
CHAPTER22=10:16:18.639
CHAPTER22NAME=Chapter 022

Step 3:

Add the chapters to the audio file (creates Nero format chapter markers):

MP4Box -add track1.aac -chap track1.chapters test.mp4

Step 4:

Convert the Nero chapter markers to Quicktime chapter markers using mp4chaps from the mp4v2 project (you will want v1.9.1 or higher):

mp4chaps –convert –chapter-qt test.mp4
converting chapters in file "test.mp4" from Nero to QuickTime

Step 5:

Rename the file from .mp4 to .m4b extension so iTunes will see it as an audiobook:

mv test.mp4 test.m4b

Proof that it works:

and VLC showing the chapters:

Of course, we aren’t putting in any tags such as “author” or “genre” in this example. Use your favorite tags editor to do so.

How to convert a laptop running Microsoft Windows 7 to a VirtualBox virtual machine

Jason L Froebe — Mon, 21 Dec 2009 16:32:53 +0000

I was very much surprised just how easy it is to convert a Microsoft Windows 7 laptop into a virtual machine running within Sun’s VirtualBox. This is what I did:

Pull the hard drive from the laptop. On my Dell Latitude, it was simply unscrewing the two screws on the bottom of the laptop marked with the hard drive simble
Attach the drive to a SATA to USB connector and plug it in to your Linux box
If you don’t have VirtualBox installed, do so now using apt-get, rpm, or whatever you use to install software
Follow How to migrate existing Windows installations to VirtualBox but make sure you specify the entire drive (i.e. /dev/sdh) and not individual partitions else you will miss the hidden partitions that Vista and Windows 7 create

You should have a working Windows 7 Virtual Machine. You’ll notice that you probably have a huge vdi file. Let’s shrink that down:

Within Windows
- download and install sdelete from Microsoft
- download and install PowerDefragmenter
- Run PowerDefragmenter on your c: drive (as administrator)
- Run “sdelete -c c:” from a cmd window (as administrator)
- shutdown windows
On the host
- run “VBoxManage modifyvdi my_disk.vdi compact” replacing “my_disk.vdi” with the name of your vdi file you created earlier
- Note that if you get a “Shrink hard disk operation is not implemented” error, then you’ve hit bug #2833 and you will want to download the latest VirtualBox to fix it.

Howto convert an entire directory of videos to play on your Sony Playstation 3 using ffmpeg

Jason L Froebe — Wed, 23 Sep 2009 14:16:00 +0000

I think a lot of people have been struggling with mass converting of videos for the ps3…
I’ve been searching for a way to mass convert my videos (mostly podcasts) to play on my Sony PlayStation 3 over the wire with Mediatomb. For a long time I’ve been using a hodpodge of mp4box and mencoder to convert the videos. The problem was that mp4box more often then not would crash or get stuck in a loop where it fills up a 1TB harddrive converting a 20mb file. There had to be a better way.

If your ffmpeg doesn’t support x264 (video) or aac (audio) encoding, like all Ubuntu Linux distributions, then you will have to recompile ffmpeg. Don’t worry, it is easier then you think!

FakeOutdoorsman over on the Ubuntu Forums posted the method to build ffmpeg from scratch:

Choose your Ubuntu

0.The instructions on the page are for Ubuntu Jaunty Jackalope 9.04 and Ubuntu Intrepid Ibex 8.10. Separate instructions are also available for other releases:

* Install FFmpeg and x264 on Ubuntu Hardy Heron 8.04 LTS
* Install FFmpeg and x264 on Ubuntu Dapper Drake 6.06 LTS

Getting the Dependencies

1. Uninstall x264, libx264-dev, and ffmpeg if they are already installed. Open a terminal and run the following:

sudo apt-get purge ffmpeg x264 libx264-dev

2. Next, get all of the packages you will need to install FFmpeg and x264 (you may need to enable the universe and multiverse repositories):

Code:

sudo apt-get update
sudo apt-get install build-essential subversion git-core checkinstall yasm texi2html libfaac-dev libfaad-dev libmp3lame-dev libsdl1.2-dev libtheora-dev libx11-dev libxvidcore4-dev zlib1g-dev

Install x264
3. Get the most current source files from the official x264 git repository, compile, and install. You can run “./configure –help” to see what features you can enable/disable. If you are behind a firewall or unable to use git, then daily source tarballs are also available.

cd
git clone git://git.videolan.org/x264.git
cd x264
./configure
make
sudo checkinstall –fstrans=no –install=yes –pkgname=x264 –pkgversion "1:0.svn`date +%Y%m%d`-0.0ubuntu1" –default

Install FFmpeg
4. Get the most current source files from the official FFmpeg svn, compile, and install. Run “./configure –help” to see what features you can enable/disable. If you are behind a firewall or unable to use subversion, then nightly FFmpeg snapshots are also available.

cd
svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
cd ffmpeg
./configure –enable-gpl –enable-nonfree –enable-pthreads –enable-libfaac –enable-libfaad –enable-libmp3lame –enable-libtheora –enable-libx264 –enable-libxvid –enable-x11grab
make
sudo checkinstall –fstrans=no –install=yes –pkgname=ffmpeg –pkgversion "3:0.svn`date +%Y%m%d`-12ubuntu3" –default

That’s it for installation. You can keep the ~/x264 and ~/ffmpeg directories if you later want to update the source files to a new revision. See “Updating Your Installation” below for more details.

Now that we have a working ffmpeg, we can go on to the converting the video files (convert_videos.sh):

#!/bin/bash

function print_usage {
echo "============================================================================================="

Getting three monitors to work with Kubuntu (Ubuntu with KDE) on a Dell Optiplex GX520 – NVidia GeForce4 MX 4000 low profile video card and the onboard Intel 82945G/GZ video card

Jason L Froebe — Mon, 11 May 2009 18:22:35 +0000

At work we have three generic LCD monitors mounted on a pole to view monitoring metrics for our Oracle & Sybase database servers. On a previous machine that was cannibalized for another task, we ran Microsoft Windows XP to drive the three monitors.

Last week we were given a hand me down desktop, a Dell Optiplex GX520 with integrated Intel 82945G/GZ video on the motherboard. When we added the NVidia GeForce4 MX 4000 low profile video card, Windows XP for whatever reason was unable to use both video cards. I proposed Kubuntu 9.04 Linux as an alternative. As it was only myself that I had to convince to make the attempt, I was hard pressed to say no

The Intel 82945G/GZ video card will be the primary card and must be attached to “Screen 0″ in the ServerLayout section.

The NVidia video card has two connectors:

A standard VGA port driven by a GeForce4 MX 4000 GPU < - Primary nvidia port
A super-video port driven by a Quadro NVS 110M

After the base install of the operating system, XWindows was only able to see the Intel video card. After much tinkering with the /etc/xorg.conf file, I was able to get all three LCD monitors to work with Xinerama. There are a number of gotchas that you might run into:

If the integrated Intel video card is set to Auto in the BIOS, the card will be completely disabled. You need to disable Auto
You need to know which Nvidia Device entry drives the VGA connector. It must be initialized prior to the S-Video port.
Disable NVidia’s TwinView and metamodes option lines in the Screen Section.
Use sudo lspci to identify the pci bus ids. You will need to put them in the Device Sections.
The integrated Intel video card must use the vesa video driver as the intel video driver will stacktrace when used with xinerama.

How to upgrade the Acer Aspire One (model 110) BIOS using a USB thumb drive

Jason L Froebe — Fri, 13 Mar 2009 18:50:39 +0000

Note that upgrading the BIOS using an USB thumb drive is NOT needed if you have Windows XP or Windows Vista installed on your Acer Aspire One netbook.

Prepare the USB thumb drive (need 64MB or larger):

Install FreeDOS on your USB thumbdrive by using Unetbootin.
Download the latest (currently 3309) BIOS from Acer’s ftp server
Extract all the files in the zip file onto your USB thumb drive

On the Acer Aspire One machine:

Insert the prepared USB thumb drive into an USB port on the Aspire One
Reboot
Hit the “F12″ button every second or so until the boot drive menu appears
Choose the option for USB HD or similar
Hit enter when presented with a PC Linux boot screen (it will boot into FreeDOS)
When the FreeDOS boot menu shows up, choose “safe mode” (no drivers loaded)
From the dos prompt, change to the c drive by typing “C:” and enter
Type “dir *.bat”, you should see 3309.bat (if you downloaded the 3309 BIOS). Run that by typing “3309.bat”
If all goes well, reboot

Above is a variant of the instructions found on Macles website.

How to install Sybase’s ODBC driver on Ubuntu Linux for ASE/IQ/Replication Server/SQL Anywhere/etc

Jason L Froebe — Tue, 13 Jan 2009 21:33:04 +0000

ASE 15.0.3 full install on Linux 32bit.
First we need to install unixODBC:

% sudo aptitude install unixodbc unixodbc-bin unixodbc-dev libstdc++5

Because of a bug within the Sybase ODBC install, we need to change /opt/sybase/DataAccess/ODBC/samples/drivertemplate.txt.

/opt/sybase/DataAccess/ODBC/samples/drivertemplate.txt:

[Adaptive Server Enterprise]
Description = Sybase ODBC Driver
Driver = /opt/sybase/ODBC-12_5/lib/libsybdrvodb.so
FileUsage = -1

Change to:

[Adaptive Server Enterprise]
Description = Sybase ODBC Driver
Driver = /opt/sybase/DataAccess/ODBC/lib/libsybdrvodb.so
FileUsage = -1

This template file is used to install the ODBC driver with unixODBC:

odbcinst -i -d -f /opt/sybase/DataAccess/ODBC/samples/drivertemplate.txt

Currently Sybase’s ODBC driver does not have a GUI component for unixODBC. I’m waiting on the bug #. Once I have it, I’ll update this post.

Now we are ready to define an ODBC dsn. We will need to create a template file to do so:

dbadev1.dsn

[dbadev1]
Description=Sybase ODBC Data Source
UserID=sa
Password=password
Driver=Adaptive Server Enterprise
Server=dba-dev1
Port=5000
Database=sybase_dba
UseCursor=1

To add it to unixODBC we need to run:

odbcinst -i -s -f dbadev1.dsn

If you wanted a system wide dsn:

sudo odbcinst -i -s -l -f dbadev1.dsn

Updated to include libstdc++5 for the newer releases of Ubuntu

VPNWiz – Cisco VPN GNOME GUI for PCF files

Jason L Froebe — Sun, 11 Jan 2009 00:33:58 +0000

The fine folks over at PhrankDaChicken@Ubuntu have come up with an excellent and simple GUI for the open source Cisco VPN client (vpnc). The nice thing is that you won’t have to decrypt the group password in your cisco PCF file as VPNWiz will read the PCF files directly!

I don’t know about you, but I’ve never had much luck with the vpnc plugin for NetworkManager when connecting to my office’s VPN.

VPNWiz - Cisco VPN GUI for Gnome

VPNWiz uses cisco PCF files to connect a GNOME linux desktop to a cisco vpn server.

Download the VPNWiz zip file, and run the install.sh file.

Go to “Apps -> Internet -> VPNWiz” to start it – follow the wizard to connect.

Click on the VPNWiz icon in the system tray to disconnect.

Get VPNWiz here.

Defragmenting XFS file systems on Ubuntu 8.10

Jason L Froebe — Wed, 31 Dec 2008 21:36:56 +0000

After using the XFS file system for a while, you might see it slow down a bit. If so, you may need to defragment the file system. Doing so is very easy but does require root access and the xfsdump package:

sudo aptitude install xfsdump

Now that we have the xfsdump package, we can use the xfs_db utility to determine the current fragmentation percentage:

$ sudo xfs_db -r /dev/sda6
xfs_db> frag
actual 95343, ideal 85809, fragmentation factor 10.00%
xfs_db> quit

As you can see, the estimated fragmentation percentage is 10%. Not bad but let’s get that down:

$ sudo xfs_fsr -v /dev/sda6
/home start inode=0
ino=138
extents before:2 after:1 DONE ino=138
ino=100725
extents before:19 after:1 DONE ino=100725
ino=103896
extents before:17 after:1 DONE ino=103896
ino=474184
extents before:3 after:1 DONE ino=474184
ino=474183
extents before:2 after:1 DONE ino=474183
ino=474185

Oops! I spoke too soon! Exchange Plugin 2.24.2 still broken for Evolution

Jason L Froebe — Sat, 13 Dec 2008 03:32:44 +0000

Back on November 5th, I reported that in my blog post Woohoo! Looks like Evolution will be able to connect to Microsoft Exchange again! that the Exchange plugin for Evolution was fixed. Well, they fixed one part but many of us still aren’t able to use the plugin.

Bug 306975: Evolution: Exchange-Connector-setup 2.24.2 unable to log in to exchange

Ubuntu 8.10, a tethered Windows Mobile 6 cell phone via USB, Firefox and Pidgin Messenger

Jason L Froebe — Wed, 10 Dec 2008 19:22:17 +0000

To tether a Windows Mobile 6 cell phone (make sure you have a data plan that allows tethering), you will need to install a few things:

sudo aptitude install subversion build-essential linux-headers-`uname -r`

Once those are installed, we need to download and build the latest usb-rndis-lite code:

svn co http://synce.svn.sourceforge.net/svnroot/synce/trunk/usb-rndis-lite
cd usb-rndis-lite/
make
## remove the existing usb-rndis drivers with clean.sh
sudo ./clean.sh
sudo make install

Before you plug in the cell phone, you will need to blacklist the rndis_wlan kernel module:

sudo echo "blacklist rndis_wlan" >> /etc/modprobe.d/blacklist
sudo rmmod rndis_wlan

Plug in your cell phone. If you type “dmesg”, you will see something like the following:

[ 152.312099] usb 4-1: new full speed USB device using uhci_hcd and address 3
[ 152.500604] usb 4-1: configuration #1 chosen from 1 choice
[ 154.138352] rndis0: register ‘rndis_host’ at usb-0000:00:1d.3-1, RNDIS device (SynCE patched), 80:00:60:0f:e8:00
[ 164.441074] rndis0: no IPv6 routers present

This is showing that the phone was found. Let’s take a look at the list of interfaces using ifconfig:

….
rndis0 Link encap:Ethernet HWaddr 80:00:60:0f:e8:00
inet addr:169.254.2.2 Bcast:169.254.2.255 Mask:255.255.255.0
inet6 addr: fe80::8200:60ff:fe0f:e800/64 Scope:Link

TX packets:51 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:2097 (2.0 KB) TX bytes:9146 (9.1 KB)

On the phone, turn on Internet Connection Sharing and connect via USB. Wait a few seconds (obtaining an ip address can take up to a minute or so) then issue the ifconfig command again:

….
rndis0 Link encap:Ethernet HWaddr 80:00:60:0f:e8:00
inet addr:192.168.0.102 Bcast:192.168.0.255 Mask:255.255.255.0

collisions:0 txqueuelen:1000
RX bytes:6063101 (6.0 MB) TX bytes:1890604 (1.8 MB)

Yay! We are connected.

In order to use Firefox, Pidgin or any other software that uses Network Manager, you need to stop the Network Manager daemon:

sudo /etc/init.d/NetworkManager stop

You will be able to use your applications again

Woohoo! Looks like Evolution will be able to connect to Microsoft Exchange again!

Installing Oracle Instant Client and DBD::Oracle on Ubuntu Linux 8.04 Server JEOS

Jason L Froebe — Wed, 22 Oct 2008 16:49:27 +0000

Ever want to just install the minimal amount of Oracle client software for client applications on Linux? Well, Oracle has provided Oracle Instant Client to do this but they have neglected to make it intuitive to install. I’ve written a couple scripts that make it easy on Linux. I’ve tested this on Ubuntu Linux 8.04 Server JEOS.

Download the files you need

Download Oracle Instant Client

Retrieve the Instant Client packages and save them to a directory (e.g. “linux 32bit”).

Instant Client Package – Basic
Instant Client Package – JDBC Supplement
Instant Client Package – SQL*Plus
Instant Client Package – SDK
Instant Client Package – ODBC

Download DBD::Oracle and place it in the build-cfg directory

Copy your tnsnames.ora file into the build-cfg directory

Download build_oracle_instantclient.sh into the directory above build-cfg directory

Save root.sh into the build-cfg directory

Build a tar ball containing everything we need in the directory format we need.

build_oracle_instantclient.sh "../linux 32bit"

Script1: build_oracle_instantclient.sh

SOURCE_DIR="$1"
BUILD_DIR=builddir
CFG_DIR=build-cfg

if [[ -z $1 ]]
then
echo "Usage: build_oracle_instantclient.sh "
exit 1
fi

if [[ ! -d "${SOURCE_DIR}" ]]
then
echo "${SOURCE_DIR} is not a directory"
exit 1
fi

find "${SOURCE_DIR}" -name "*.zip" -type f -exec unzip {} \;

if [[ -d instantclient_11_1 ]]
then
TMP_DIR=instantclient_11_1
elif [[ -d instantclient_10_2 ]]
then
TMP_DIR=instantclient_10_2
else
echo "unable to determine extraction dir"
exit 1
fi

if [[ -d ${BUILD_DIR} ]]
then
rm -rf ${BUILD_DIR}
fi

mkdir -p ${BUILD_DIR}
mkdir -p ${BUILD_DIR}/bin
mkdir -p ${BUILD_DIR}/doc
mkdir -p ${BUILD_DIR}/java
mkdir -p ${BUILD_DIR}/lib

cp ${CFG_DIR}/* ${BUILD_DIR}
mv ${TMP_DIR}/*README* ${BUILD_DIR}/doc
mv ${TMP_DIR}/*.html ${BUILD_DIR}/doc
mv ${TMP_DIR}/*.htm ${BUILD_DIR}/doc
mv ${TMP_DIR}/lib* ${BUILD_DIR}/lib
mv ${TMP_DIR}/*.jar ${BUILD_DIR}/java
mv ${TMP_DIR}/sdk ${BUILD_DIR}
mv ${TMP_DIR}/* ${BUILD_DIR}/bin

cd ${BUILD_DIR}/lib
ln -s libclntsh.so.* libclntsh.so
ln -s libocci.so.* libocci.so
ln -s libsqora.so.* libsqora.so

cd ..
tarball=`echo ${SOURCE_DIR} | tr ‘ ‘ ‘-’`
tarball=`basename ${tarball}`
tarball=Oracle-${TMP_DIR}-${tarball}
tar cvf – * | gzip -9c > "../${tarball}.tgz"

cd ..
rm -rf ${BUILD_DIR} ${TMP_DIR}directory>

Once we have the tar ball, we can copy that file to any compatible Linux system, extract it and run the root.sh file which will copy the install to /usr/local/oracle/InstantClient, set up the system variables and build DBD::Oracle for you.
