Share Internet Connection On VirtualBox

The following will explain howto sharing internet connection on virtualbox which ubuntu act as host and windows xp as guest.

Note: Type all the following commands in a root terminal, DO NOT use sudo.

1. Start by configuring the network card that interfaces to the other computers on you network:

# ifconfig ethX ip

where ethX is the network card and ip is your desired server ip address (Usually 192.168.0.1 is used)

2. Then configure the NAT as follows:

# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE

where ethX is the network card that the Internet is coming from


# echo 1 > /proc/sys/net/ipv4/ip_forward

3. Install dnsmasq and ipmasq using apt-get:

# apt-get install dnsmasq ipmasq

4. Restart dnsmasq:

# /etc/init.d/dnsmasq restart

5. Reconfigure ipmasq to start after networking has been started:

# dpkg-reconfigure ipmasq

6. Repeat steps 1 and 2.

7. Add the line "net.ipv4.ip_forward = 1" to /etc/sysctl.conf

# gedit /etc/sysctl.conf

8. Reboot. (Optional)

Speed Up Internet in Ubuntu

Most of the slow internet connection caused by ipv6 environment. ipv6 slows down the ipv4 environment if the router out the door does not understand ipv6 and for most people ipv6 is not needed.Try this tricks :

Open Terminal, and type :

sudo gedit /etc/modprobe.d/aliases



at the line, alias net-pf-10 ipv6, you can 'comment' (#) or just add off at the end of the line as shown below..

Reboot & see the difference..

TimeVault

TimeVault is a simple front-end for making snapshots of a set of directories. Snapshots are a copy of a directory structure or file at a certain point in time. Restore functionality is integrated into Nautilus - previous versions of a file or directory that has a snapshot can be accessed by examining the properties and selecting the 'Previous Versions' tab.

Snapshots are protected from accidental deletion or modification since they are read-only by default. The super-user can delete intermediate snapshots to save space, but files and directories that existed before or after the deletion will still be accessible.

A snapshot is a copy of a directory at a certain point in time. Snapshots don't use space for the files that haven't changed but instead simply add a link to the same data on disk. When a file (link) is deleted, the link count for the data on disk is decremented. When it reaches 0 the data is marked free in the allocation table and new data can then be written to those blocks. As most allocations of data have only 1 file that links to them data is usually freed when its file is deleted.

Only files are hard-linked this way. In most filesystems directory hardlinks are disallowed because they can cause endless recursion. Apple specifically modified their system by adding mandatory recursion detection to prevent infinite loops, ostensibly purely for their backup software.

tar

Introduction to Tar

The Tar program provides the ability to create tar archives, as well as various other kinds of manipulation. For example, you can use Tar on previously created archives to extract files, to store additional files, or to update or list files which were already stored.

Initially, tar archives were used to store files conveniently on magnetic tape. The name "Tar" comes from this use; it stands for tape archiver. Despite the utility's name, Tar can direct its output to available devices, files, or other programs (using pipes), it can even access remote devices or files (as archives).

Additional information about the project, including links to the project development page and file downloads, is available from the GNU software directory.

Downloading Tar

Stable versions of GNU Tar can be found on in the subdirectory /gnu/tar/ on your favorite GNU mirror. For other ways to obtain Tar, please read How to get GNU Software

Latest intermediate snapshots are available from tar snapshot ftp. Alpha releases are distributed from alpha.gnu.org.

For information about CVS access, alpha releases, patches, etc., please see the project's home page.

rsync

rsync is an open source utility that provides fast incremental file transfer. rsync is freely available under the GNU General Public License and is currently being maintained by Wayne Davison.

If you are running (1) an xattr-enabled rsync older than 3.0.2, (2) a writable rsync daemon older than 3.0.0, or (3) a version of rsync older than 2.6.6, please see the rsync security advisory page.


Rsync version 3.0.6 released

May 8th, 2009

Rsync version 3.0.6 has been released. This is a bug-fix release.

See the release NEWS for the details of what changed since 3.0.5. The latest manpages are also available for both rsync and rsyncd.conf.

The source tar is available here: rsync-3.0.6.tar.gz (signature), with a tar file of the "patches" directory now released in a separate file: rsync-patches-3.0.6.tar.gz (signature),rsync-3.0.5-3.0.6.diffs.gz (signature). and the diffs from version 3.0.5 are available here:

rdiff-backup

rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks. Also, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted. Finally, rdiff-backup is easy to use and settings have sensical defaults.

Download:

rdiff-backup is GPLed (anyone can download it, redistribute it, etc.).

The keys used to sign the releases are available in the project members' keyring.

Mondo Rescue

Mondo Rescue is a GPL disaster recovery solution. It supports Linux (i386, x86_64, ia64) and FreeBSD (i386). It's packaged for multiple distributions (RedHat, RHEL, SuSE, SLES, Mandriva, Debian, Gentoo).

Duplicity

Duplicity backs directories by producing encrypted tar-format volumes and uploading them to a remote or local file server. Because duplicity uses librsync, the incremental archives are space efficient and only record the parts of files that have changed since the last backup. Because duplicity uses GnuPG to encrypt and/or sign these archives, they will be safe from spying and/or modification by the server.

The duplicity package also includes the rdiffdir utility. Rdiffdir is an extension of librsync's rdiff to directories---it can be used to produce signatures and deltas of directories as well as regular files. These signatures and deltas are in GNU tar format.

Current development status

Duplicity is still in Beta. As any software, it may still have a few bugs, but will work for normal usage and is in use now for large personal and corporate backups. If you have questions try the mailing list. Bug reports and bug fixes can be entered through the Savannah project page.

In theory many protocols for connecting to a file server could be supported; so far ssh/scp, local file access, rsync, ftp, HSI, WebDAV, and Amazon S3 have been written. Currently duplicity supports deleted files, full unix permissions, directories, and symbolic links, fifos, and device files, but not hard links.

Download

Refer to the Changelog for overview of the recent changes and to GNU Changelog for the gory details from CVS.

The current stable release is 0.5.18, released May 20, 2009.

The current development release is 0.6.00, released June 6, 2009.

Older versions are also available for the budding historians in the downloads area.

Michael Terry maintains a Ubunta PPA (Hardy and Intrepid) for deja-dup and duplicity. Updates to the PPA will lag behind the above updates, so please be patient.

Edgar Soldin maintains ftplicity, a shell front end to duplicity for encrypted backups on non-trusted ftp servers.

All the code here is GPLed (free software). Duplicity is also part of the Fedora, Debian, and Ubuntu distributions of GNU/Linux.

Requirements

Duplicity requires a POSIX-like operating system. It is best used under GNU/Linux. It also requires:

If you install from the source package, you will also need:

  • Python development files, normally found in module 'python-dev'
  • librsync development files, normally found in module 'librsync-dev'

DirSync Pro

DirSync Pro (Directory Synchronize Pro) is a small, but powerful utility for file and folder synchronization. DirSync Pro can be used to synchronize the content of one or many folders recursively.

Using DirSync Pro you can make incremental backups. In this way you'll spare lots of time because you don't have to copy all the files each time you want to update your backup; only new/modified/larger files would be copied.

Use DirSync Pro to easily synchronize files from your desktop PC to your USB-stick (PDA, Notebook, ...). Use this USB-stick (PDA, Notebook, ...) to synchronize files to another desktop PC.

Unlike many other synchronization software, DirSync Pro is Open Source; it is 100% free of charge, 100% free of commercial text, 100% free of advertisements and 100% free of spyware. You can use it as long as you like, without any limitations in time or funcationality. You can freely distribute it according to GPL3.

DirSync Pro is programmed completely in platform independent Java™ so it can be run under nearly every modern operating system including Windows™, Linux™ and Macintosh™.

DirSync Pro has a user-friendly User Interface which helps you configure many options to your needs. You can use DirSync Pro also through the command line which makes it very flexible for running in batches.

Presentation

dar is a shell command that backs up directory trees and files. It has been tested under Linux, Windows, Solaris, FreeBSD, NetBSD, MacOS X and several other systems, it is released under the GNU General Public License (GPL). Since version 2.0.0 an Application Interface (API) is available, opening the way for external/independent Graphical User Interfaces (GUIs) like kdar. This API relies on the libdar library, which is the core part of DAR programs; as such, the API is released under the GPL. Consequently, to use the API, your program must be released under the GPL as well.

Cpio

GNU cpio copies files into or out of a cpio or tar archive. The archive can be another file on the disk, a magnetic tape, or a pipe.

GNU cpio supports the following archive formats: binary, old ASCII, new ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar. The tar format is provided for compatability with the tar program. By default, cpio creates binary format archives, for compatibility with older cpio programs. When extracting from archives, cpio automatically recognizes which kind of archive it is reading and can read archives created on machines with a different byte-order.

Downloading Cpio

GNU cpio can be found on http://ftp.gnu.org/gnu/cpio/ or one of the mirrors.

Alpha releases of the development version can be downloaded from alpha.gnu.org.

Cobian Backup

Cobian Backup is a multi-threaded program that can be used to schedule and backup your files and directories from their original location to other directories/drives in the same computer or other computer in your network. FTP backup is also supported in both directions (download and upload).

Cobian Backup exists in two different versions: application and service. The program uses very few resources and can be running on the background on your system, checking your backup schedule and executing your backups when necessary.

Cobian Backup is not an usual backup application: it only copies your files and folders in original or compressed mode to other destination, creating a security copy as a result. So Cobian Backup can be better described as a "Scheduler for security copies". Cobian Backup supports several methods of compression and strong encryption.

BackupPC

BackupPC is a high-performance, enterprise-grade system for backing up Linux and WinXX PCs and laptops to a server's disk. BackupPC is highly configurable and easy to install and maintain.

Given the ever decreasing cost of disks and raid systems, it is now practical and cost effective to backup a large number of machines onto a server's local disk or network storage. This is what BackupPC does. For some sites, this might be the complete backup solution. For other sites, additional permanent archives could be created by periodically backing up the server to tape. A variety of Open Source systems are available for doing backup to tape.

BackupPC is written in Perl and extracts backup data via SMB using Samba, tar over ssh/rsh/nfs, or rsync. It is robust, reliable, well documented and freely available as Open Source on SourceForge.

Features

* A clever pooling scheme minimizes disk storage and disk I/O. Identical files across multiple backups of the same or different PCs are stored only once resulting in substantial savings in disk storage and disk I/O.
* One example of disk use: 95 latops with each full backup averaging 3.6GB each, and each incremental averaging about 0.3GB. Storing three weekly full backups and six incremental backups per laptop is around 1200GB of raw data, but because of pooling and compression only 150GB is needed.
* Optional compression support further reducing disk storage. Since only new files (not already pooled) need to be compressed, there is only a modest impact on CPU time.
* No client-side software is needed. The standard smb protocol is used to extract backup data on WinXX clients. On linux clients, tar over ssh/rsh/nfs is used to backup the data. With version 2.0.0, rsync is also supported on any client that has rsync or rysncd.
* A powerful web (http/cgi) user interface allows administrators to view log files, configuration, current status and allows users to initiate and cancel backups and browse and restore files from backups.
* A full set of restore options is supported, including direct restore (via smbclient, tar, or rsync/rsyncd) or downloading a zip or tar file.
* Supports mobile environments where laptops are only intermittently connected to the network and have dynamic IP addresses (DHCP).
* Flexible configuration parameters allow multiple backups to be performed in parallel, specification of which shares to backup, which directories to backup or not backup, various schedules for full and incremental backups, schedules for email reminders to users and so on. Configuration parameters can be set system-wide or also on a per-PC basis.
* Users are sent periodic email reminders if their PC has not recently been backed up. Email content, timing and policies are configurable.
* Tested on Linux, Freenix and Solaris hosts, and Linux, Win95, Win98, Win2000 and WinXP clients.
* Detailed documentation.
* Open Source hosted by SourceForge and freely availble under GPL.

PCLinuxOS 2009.1 Final Released

The Ripper Gang is pleased to announce the final public ISO release of PCLinuxOS 2009.1.

This release features kernel 2.6.26.8.tex3, KDE 3.5.10, Open Office 3.0, Firefox 3.0.7, Thunderbird 2.0.0.14, Ktorrent, Frostwire, Amarok, Flash, Java JRE, Compiz-Fusion 3D and much more. We decided to use kde3-5-10 as our default desktop as we could not achieve a similar functionality from kde4. We will however offer kde4 as an alternative desktop environment available from the repository once we stabilize it. PCLinuxOS is an rpm based distribution utilizing apt-get with a Synaptic Software Manager frontend. In addition to the above PCLinuxOS comes with mklivecd GUI, a nice utility to build a custom live CD from your install. Install or remove what you want then remaster your own cd. Great for backups or to give to friends. PCLinuxOS is also known as as rolling release distribution. What that means is you install once and update it when new applications become available from our repository.

Special thanks goes out to gettinther, Sal, Linuxera, Neverstopdreaming, Davecs, gri6507, Stumpy842 and etjr. Also to Enki Consulting for hosting the website and ibilio.org for hosting the software packages.

Frepple

FrePPLe is a lightweight open source framework that easily and quickly delivers a solution for production planning problems. The primary focus is on the discrete manufacturing industry.

Production planning software traditionally has been an area with plenty of home-grown, extremely specialised and/or very primitive solutions.
Strangely enough, while creative and innovative open source solutions pop up in all computing areas, production planning software still tends to be a very closed world full of academic, proprietary and expensive solutions. Till now...
FrePPLe is the first open source production planning toolkit for your day-to-day planning problems.

For the developer community, the project is also trying to establish a common ground framework for planning applications. Rather than rebuilding the basic foundation from scratch over and over again, developers can now leverage a proven framework to extend with their own extension modules.
New workflows and functionality can now be built much quicker and easier.


The features in brief:

FrePPLe has two main components.

  1. The first one is a core library containing the model and the solving algorithms.
    It is generic and can be used in a number of applications.
  2. A second component is a flexible user interface and database layer to support the core library.
    It takes care of the maintenance of input data, reporting of the plan results, and data integration to other systems.

The key features of each component are:

  1. FrePPLe core library

    • FrePPLe comes as a 'library' developed in C++.
      It has no graphical user interface and requires to be deployed as part of another application.
      Different applications are envisioned:
      • Standalone application for use on the command line
      • Accessible from programming languages such as Java, Python, Perl or Visual Basic
      • Can be linked into your own C or C++ application

    • Modeling and solving framework for discrete manufacturing environments.
      Key modeling constructs are:

      • Buffer
      • Resource
      • Operation
      • Demand

    • Heuristic solving algorithm respecting capacity, material and leadtime constraints.

    • XML-based data input and output, in addition to the public C++ API.

    • Very fast! Performance and scalability have been a consideration from day one...

    • Extensible and customizable architecture.
      New modeling constructs and solving algorithms can be developed in C++ and loaded as a plugin module.
      Standard plugin modules include:

      • Python is used as scripting and customistion language.
        The embedded interpreter has access to the frePPLe objects in memory, as well as the rich functionality in the Python standard libraries. The powerful combination allows flexible and performant scripting, integration and customization.

      • The forecast module implements algortihms for forecasting future demand based on the demand history, and also supports netting customer orders from the forecast.

      • The linear programming module implements a mathematical solver that complements the heuristic based built-in solver.

    • Supported on Linux and Windows environments.

    • Licenced under the GNU lesser general public license.

  2. FrePPLe user interface and database layer
    A planning solution consist of much more than the core solver algorithms...
    screenshots It includes data maintenance, reporting, data integration to other systems, workflows, job schedules, etc...
    A front-end for the core library is required to meet these requirements with a maximum of flexibility.

    • Based on the Django web application framework.
      Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design.
      For frePPLe it provides an excellent toolkit:
      • Flexible and portable modeling of database layer: powerful and intuitive object-relational mapper
      • Flexible and performant framework for web applications: auto-generated administration user interface, template system, cache system, internationalization, ...
      • Performant and scalable

    • Highly customizable and extendible.

    • The web application can be deployed on a web server, supported by a backend database.
      It can also be installed as a desktop application for a single user.

    • Supports the PostgreSQL, MySQL, SQLite and Oracle databases.

    • Full support for internationalization and localization.
      The user interface supports Unicode, allowing characters of any language to be handled.
      Reports can be translated to the user's local language.

    • Supported on Linux and Windows environments.

    • Licenced under the GNU lesser general public license.
