Virtualizes a Linux server on the fly with RSYNC

 

LOGO_virtualized_vmware_S

You'll need a lot of patience...Since there is no VMWARE Converter for Linux...

My objective is to virtualizes my Internet server running SUSE in a VMWARE to ease the migration to a more powerful and up to date server.

 

I am using RSYNC since:

  • I have no access to the machine, So I can't stop the server and make a binary images of the disk as the server is in a STRATO data center in Germany (Berlin)
  • I don't like operations down time.

I HAVE TO virtualize my server because:

  • The operating system SuSE is too old and is no more security patches available.
  • I want to have a local reference in VMWARE of my Internet server.

This tutorial can be see as an add-on of this one : http://www.linuxjournal.com/article/9942 (very good by the way) I just complete the missing steps or document some issues I've encountered..

How to Secure Your Windows Computer and Protect Your Privacy

Anybody using internet should really read this article. While targeted at windows users, most of the
rules also apply to users of Linux and mac.

"Security consultant Howard Fosdick has contributed the latest entry in the
2008 OSNews Article Contest: a highly detailed examination of security and privacy on the
Windows platform, and how to use free
software tools and a little knowledge to protect your privacy online.
Do you know that --

  • Windows secretly records all the web sites you've ever visited?
  • After you delete your Outlook emails and empty the Waste Basket, someone could still
    read your email?
  • After you delete a file and empty the Recycle Bin, the file still exists?
  • Your computer might run software that spies on you?
  • Your computer might be a bot , a slave computer waiting to perform tasks assigned
    by a remote master?
  • The web sites you visit might be able to compile a complete dossier of your online activities?
  • Microsoft Word and Excel documents contain secret keys that uniquely identify you? They also
    collect statistics telling anyone how long you spent working on them and when. "

Secure, Safe, Fast Linux Hosting

I know that Secure, Safe, Fast Linux Hosting sound silly as nothing can be fast and secure at the same time, but I've compiled a list of things that are worth doing if you are maintaining your own server. This list is clearly targeted for people running an open source stack made of Apache, MySQL, PHP and Linux.

This list is an ongoing work, thta is why it has also a version number in it (v1.0). As soon as I will learn new tricks, the list will be updated.

By clicking read more, You'll be able to go through the checklist, or maybe you'll prefer the mindmap version HERE
