VMware ESX Server 3i

It's been a while away from the blog. Been busy with new products related to Symantec. Well as you may all know Symantec is company famous for anti virus software right?? well not at all, it is selling antivirals for home users and enterprise market but the company is armored with more than 35 products itself and continue t grow everyday by technology accusation's. Anyway I went too far with Symantec products because now I'm working on those products.

So VMware back into my life with their latest edition for the enterprise market. VMWare ESX server. Now we all ma have used VMware workstation for and VMware server in our home pc's for testing applications and operating systems. But VMware ESX is the big daddy of all of them and actually involve in server virtualization, resource management and cost savings...etc. This product is not depend n windows or Linux as a host OS but starting with it's own OS! By doing so it make sure it'll take minimum hardware resources from your actual serer and let the raw power to be distributed to the virtual PCs. Most of the enterprise data centers move to VMware ESX for numerous reasons and few are as follows,

1 Decreases power, cooling, floor space and infrastructure.
2 Simplifies disaster recovery and business continuity requirements.
3 Increases server utilization from the typical averages of 5-15% to 60-80%.
4 Faster deployment of information technology resources reduces time to market.
5 Lower operational costs associated with reduced resource management and administration.
6 Improves application performance by dynamically adapting storage and server resources to meet peek usage cycles. and much much more.
So I thought of sharing some VMware guru's articles into this blog to make it more useful for everyone.

Happy Virtualization to all.

Happy New Year 2008!!!

It's a another fresh start and lots of things to cover. So how it's going to be for us in IT side? Well let's ride and see...

P2V (Physical to Virtual) Conversion

This is the concept that been buzzing around the IT world. Convert your physical machine to Virtual.(Not exactly the correct meaning as it is, but we’re talking about converting the OS and the apps in the physical to virtual OS that can be run on any platform. VMware company goes extra mile to introduce this method and really keep on their word on it. They are so keen about this concept and released out a free tool to people to test this method. This software can be downloaded here (http://www.vmware.com/download/converter/)

Actually they have come with 2 version and more details can be found from the VMware web site itself.

So I took the liberty of testing this out in our office Exchange server!!!!! (People don’t try this out in your office unless you got a another job) I have given a task of cleaning out the mess in our exchange server and remove the unnecessary mail boxes. Knowing this clean is not the best method than a fresh installation I thought of trying this out. So my first task is downloading the software and then install it to the Exchange server itself. After that I make sure we have a spare server or a hard disk with enough free disk capacity for the migration. Armed with all the necessary tools and the brains start the process. Cannot recall the whole time it took for the conversation but I assume it was around 6 hours. (I start the process in a weekend and found it was completed when I arrived to office on Monday)

So what I found is a 30GB vmdk file! Start the Virtual server in a dual core machine and start the vhdk file assigning 1GB ram. The process went smoothly and after the bootup I had to install the VMware tools get the connectivity with the actual network. After assigning the IP connectivity I brough down the physical PC down. I ran the company Exchange server in a virtual environment for 2 weeks time. The only problem I found is network card stop sending packets and loosing the connectivity once in a while. I assume I have not done a proper house work for the virtual file. (Assuming I have to boot the virtual OS in safe mode and remove the existing network cards and then let the VMware tools to install its emulated network drivers.) But apart from that whole project is a success.

I really like to hear from others who have done a process like this. My next plan is to host a SharePoint portal server and our anti virus server (Symantec Endpoint Security) in virtual appliances and host in one physical server.

Virtualization is a cool concept and sooner or later it will crawl into you office too. So be prepared!!!

So I'm MCSA now

Well I'm so glad I made it. I've been out of the certification track after doing my Small Business Server exam in year 2006.
It relly took me 2 months time and my previous job experince really helped me in that. I still think SBS exam is really worth for the money. The product itself really cool and really look forward to post some information about it soon. One cool product I start to fall in love is Microsoft ISA server 2004/2006. I know Cisco rocks in everyones minds, but this is a cool product to give a serious thouhgts. Glad to Local IT security giving attention to that. Look forward to share some information with other peer members about this product.

So that's my small roaring about the MCSA and look forward to get few more certificates under my belt and look foward to Windows 2008.

Ubuntu back in action

Ubuntu Linux has released their latest desktop version-Ubuntu 7.0.4 aka "Feisty Fawn"

In my previous articles I've mentioned I use the version 6.06 and 6.10 and been really impressed with their easiness of usage. New version has even more promsing features and also options to data and user migrations from windows operating systems. The truth is Microsoft Vista has been requesting lots of resources leaving it's customer base with less options. Most of them are looking for alternatives and to keep their existing PC's. Specially in Asian countries windows Vista migration might get slower phase due to the Computer hardware component prices. Microsoft still hasn't come up with good pricing schmene for the developing countries and this is another kep point they loose average Joe's. Anyway I've not yet installed the latest version cause it's still on it's way through ADSL line (lol)
Will update the blog one I get my hands dirty on the product. But in da meantime I found out the following features and offered bt the product,

Windows migration tool - The new migration tool recognises Internet Explorer favorites, Firefox bookmarks, desktop wallpaper, AOL IM contacts, Yahoo IM contacts and imports them in Ubuntu. This offers easier and faster migration for new users of Ubuntu and individuals wanting to run a dual partition. In addition to single accounts, you can migrate several users' settings in Ubuntu. (I think this may get rapid improvement to support more data to be transferred)

Easy installation of multimedia codecs -Playing an MP3 or other media file just got a lot easier. If the required pieces are not yet installed, 7.04 will get the correct codecs for you, no more searching and no need for long and complicated instructions.

Easier connection to wireless networks - This is really timesaver. Just like windows XP wireless configuration options. Configuration going to be breeze.

apart from that Ubuntu 7.0.4 using the latest kernel (2.6.20) and Gnome's most awating 2.18 desktop enviroment.

Cannot clear ARP cache

I've been facing this matter numerous times. Couldn't find the cause of it until today. This time problems occurs in windows 2003 server computer after installing RRAS (Routing and Remote Access Service) . As soon as I start the service server couldn't access the internet and won't allow new clients to join the network. Stopping the service allowed me to connect to the service but won't allow to join new clients to the domain.
After quick Googling I found out this problem is common for all windows versions. Foud out various answers and most popular one is clearing the ARP cache through command line (netsh interface ip delete arpcache) Microsoft has been kind enough to offer the solution starting from ABC (http://support.microsoft.com/kb/314067)
Just a another day in computer nightmare! Hope to see a ray of light tomorrow. Will post as soon as I come up with an answer.
Cheers

How to survive in OS battle in year 2007

First of all wish everyone a Happy Ney Year! We're on the era of expecting windows VISTA to come out and surprise windows fans. I've once reviewed the windows Vista and couldn't find much interesting things to stick around it. I'm really disappointed to hear minimum/ recommended hardware requirement for the OS. You can run any Linux OS in very good condition in that kind of specs.(This is my personal blog so bare with my ideas...lol)
But things may change as usual. If we look into the Windows OS history most of us keep on moaning and blaming when they initially released their OS. I remember most of us blamed windows XP and told we'll stick to to windows 2000 Professional no matter what. But it changed ultimately. Even though we moan about the windows Vista hardware requirement in the market we se hardware components exceeding Vista requirement and far more capability packed. But it's the question is how far we want to go on purchasing hardware and software to do the same task we did years back. As always security and information theft is a the biggest risk in the current and present future. So software vendors have busy time looking after their product and keep on covering their products t minimize such attacks.
As a summary of the situation I see year 2007 will be interesting place for OS battle. With Microsoft windows Vista and their latest server product range their will be significant change from the fans for the Linux world. They will think twice before jumping to OS.

Is Ubuntu really play well than windows?

I've posted about the Ubuntu Linux distro in my earlier post. Since that I've been regularly using it as my main OS in my laptop. I've to admit everyday I'm loving it. I wonder why I didn't make that move long time ago. Yeah you can argue saying windows support various software and easy to install but what the heck Linux got more software than windows. You'll almost find a software to competitive to windows software. BTW Linux is not an operating system to a geek who wanna try all the latest software all the time but hey I got a answer for that too. Save the money to purchase VMware for Linux and install Windows virtually if you can't lave M$. (I also need M$ due to my clients support ) So I keep it in my virtual environment in order to support clients. I'll sharing some of distro pics in order to share my experience with Linux. Anyway I found downside also, for gamers Linux will be no no..pls go to windows. But I found simple games to enjoy.

Linux OS in a USB Flash Drive

Most of us now aware of the Bootable OS CD's. For those who is new to this it's just a CD that will load the whole operating system into teh memory without thouching your Hard disk. Most of the tiem the main OS will be Linux. For windows XP users who needs to peek into the Linux world, this si teh ideal soultion. They can feel the OS without installing it to their system. But now time has change bootable option has been step forward to USB flash drives! This is much more faster thanks to the USB 2.0 . This means it's much more faster than loading from the CD. Otehr advantage is your CD-rom is free for you to use and you can recover data from your non bootable HDD and can write it to a writable CD. So without much introduction I'll introduct to one of the link I found in a web search.

http://www.pendrivelinux.com/index.php (This site provide instructions to install various Linux flavours to USB drives. The instructions are easy to follow to a newbie.) If you're still not sure to do this then go ahead and buy a USB flash drive preinstalled with Linux OS. Good option will be buying the following product,

Cheers!

Free Online data backup

There are many commercial online backup software and products available for a resonable price. While searching through the net I found a free edition which gives away 2GB online space to backup. The usage is very easy though restore option is not straight forward but not difficult at all. (After all it is a free verion) They also offer commercial version starting with 30GB options.

Using UBUNTU in my Laptop

In my previous post I've mention about the Ubuntu Linux. This is the most famous and easy to use Linux OS I've found. I decided to move to Linux instead of Windows in my Dell Inspiron 6000 laptop. To my surprise I found Linux Os if much more quicker in responding time than the Windows XP. I'm really happy about that speed gain up. My machine spec is Intel M1.6 GHz 512 MB Ram, 40 GB 5400RPM HDD,...oh and share memory for the Intel VGA card.

First start with Ubuntu Linux 6.05 version and found out they have released the 6.10 version on 26th October 2006. This one code name as Edgy Eft. Upgrade process too long time than the new installation but it has greatly improved the speed. I prefer o stick with Gnome desktop environment. It is less graphics and response is much quicker. But if you're moving from Windows environment this will not make you unhappy.

Vmware player in Ubuntu Linux

I've been searching forums and Googling about this one. I find various answerers to this. Some of them are very easy to follow just bring up the terminal window and type one command and it'll do the rest!!(Eg : sudo apt-get install vmware-player)
I was really happy I don't have to download any packages and go through lots of fiddling, unfortunately this didn't work for me. I get and error message when I tried this option. So what case the problem? It's just a simple matter of enabling the correct repositories. All you have to do is,

system-->software sources-->(select) software restricted by copyright or legal issues (multiverse).

After that it will update the sources list with additional download locations. So that's it. Go to the terminal windows (command prompt in windows language ...lol) and type sudo apt-get install vmware-player.

Welcome to Linux World

I've been always curious to try out new operating systems. Trying to move away from expensive software like Microsoft and move to the freedom world called Linux. I think I found the perfect Linux distro to that which is "Ubuntu" This is one of the user friendly Linux distro for beginners. In my understanding with Linux I will prefer this one most. At the moment of writing the latest version is 6.10 called "Edgy" . As many Linux distributions this one also allows you to test this OS in bootable CD. Ubuntu linux is having few flavors. Kubuntu which is default desktop is KDE. and Ubuntu is having Gnome. Even though you can try both in the same environment I found Gnome is much less resource hungry and works faster. I've been used to Windows environment and thought moving to Linux will be really difficult. We all have been habbit of GUI environment of Windows and really afraid to go away from clicking mouse buttons (Lol). Anyway Linux GUI has been improved vastly. It almost like you're using windows environment and the great thing is applications are loading very faster. I hope the following links will provide you appearance of the Ubuntu linux and make a apatite to try them out. After all don't be afraid to freedom!!

Walking through Windows Vista

Always wanted to get my hands into latest software and test them out. I was so anxious to get my hands into Vista and try it out. Heard they released teh RC1 23rd of September for public. Manged to download a small 2.3 GB iso file. (lol) At first I went through upgrading which took nearly 8 hours and ended up with BSOD!
Next armed with a another hard disk went through the installtion which took nearly 1.30 hours. My machine specs are (AMD XP 2500+, 1024 Ram and 120 GB 5400 RPM hard disk) Windows Vista gave me only 3.4 points out of 10 to my machine! (too bab) But all along it runs smoothly. I am quite happy with that performance but so far didn't dig too much into the features even though I notice Microsoft had taken quite a step improving the visual effect rather than finxing the software problems (lol) I've attached few pics to show how it looks like. I couldn;t run my favourite programs like Alcohol120% CD emulating software and Nero. But manged to install the VM Ware workstation software in it.

Testing MS Office 2007 Beta 2

Playing Diablo 2

Finally manged to finsihed the game after 3 days contiouns battle. I've to admit in the end of the game I used to registry editor other wise I'll be playinh this for months. 2 years ago I plyead half of this game for 6 months but never saw the ending. Now it's time to try this out in online mode!!
I've to admit I'm like to play computer games as a hobby. I whish I can upgade my AMD XP desktop in order to play better games but not doing so will also let me time to spend in my studies. Well I'm fooling my ownself!!!

SBS Specialist

Finally passed the Small Business Server Administration Exam. this one is really cool, because the product itself test your knowledge in Exchange, ISA and windows 2003 server itself. I've to admit passing the exam really doesn't mean I'm a specialist in that product. Experience has to be count into that in order to wear that crown. But in the other hand I've got MCP to my credential list which is a good thing.

Learn by watching!

While browsing through the net I came accorss a good web site. (http://www.blogcastrepository.com) This is a cool web site. You can watch videos, show how to do some of the Microsoft tasks. If you're a pro you can publish your own blogs to the site.

ISA, Exchange and SBS update

After installing the SBS server in a test machine I got the chance to test the ISA server for the first time. I've to admit the GUI interface is pretty cool. I think newbies will love how simplify the the tasks to be created and started. After all Microsoft has thrown away some utilities that really help newbies.

I found ISA Server best analyzer tool & MBSA (Microsoft Baseline Security Analyzer) are really helpful. Thumbs up for the MS guys developing these tools. It's really easy to find how powerful or how weak is your server and what patches you're missing. So if there are any SBS administrators (newbie and pro) I think this is a must tool in their toolbox.
