How to install any Windows Role from the command line

How To Theory

Recently I was working with Windows 2008 Server Core. I was trying to install a role and quickly missed “Add/Remove Role Wizard”! After doing a bit of research I found that with everything in Windows Core you can run a command that will do the same thing  as it’s GUI counter part. Unless you are very gifted, I doubt any mortal would remember all the roles you can add. To find out what the names of roles you can install you must type the command: 

ServerManagerCmd –query

Now that you know how to query the server for roles you are probably wanting to get to the good stuff and actually Install a role you would type:

ServerMangerCmd -i NameOfRole

Example

Now that you know how it works lets install something like Powershell and IIS from the server’s command line. Let’s Go!

Windows 7 RC and Windows XP Mode

When?

Microsoft has announced that the Windows 7 Release Candidate (RC) will be available April 30th for download by MSDN and TechNet subscribers and public availability beginning on May 5th.

For those wanting it faster, it has apparently leaked onto various torrent trackers already.

Also today, Microsoft unveiled details of Windows XP Mode, a virtual Windows XP environment running under Windows Virtual PC. Applications can be installed directly to the virtual Windows XP environment and will be runnable directly from the Windows 7 desktop little native Windows 7 applications.

About Windows 7 Windows XP Mode

A Windows SuperSite story about the Windows XP Mode notes the following details:

XPM is built on the next generation Microsoft Virtual PC 7 product line, which requires processor-based virtualization support (Intel and AMD) to be present and enabled on the underlying PC XP Mode consists of the Virtual PC-based virtual environment and a fully licensed copy of Windows XP with Service Pack 3 (SP3). It will be made available, for free, to users of Windows 7 Professional, Enterprise, and Ultimate editions via a download from the Microsoft web site. (That is, it will not be included in the box with Windows 7, but is considered an out-of-band update, like Windows Live Essentials.) XPM works much like today’s Virtual PC products, but with one important exception: As with the enterprise-based MED-V (Microsoft Enterprise Desktop Virtualization) product, XPM does not require you to run the virtual environment as a separate Windows desktop. Instead, as you install applications inside the virtual XP environment, they are published to the host (Windows 7) OS as well. (With shortcuts placed in the Start Menu.) That way, users can run Windows XP-based applications (like IE 6) alongside Windows 7 applications under a single desktop.

This is a very important move, many companies are unable to use Windows Vista and would be unable to use Windows 7 because they need to support a Windows XP application that would fail to run under these newer environment. Using Virtual PC or Virtual Server does is difficult for end users as it is not seamless on the desktop and requires a Windows XP license. Windows XP Mode would solve both issues. Expect Microsoft to strip out much of Windows’ backward compatibility support in future versions in favour of making Windows XP mode an standard part of a Windows install.

How to setup and configure Webmin

Install Webmin

Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more.  Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely. Currently there is no Webmin package in the Ubuntu repositories. This tutorial will explain how to Install Webmin in Ubuntu Intrepid Ibex

You can install webmin for your server web interface to configure apache2,mysql,FTp servers and many more.Now we will see how to install webmin in Ubuntu 8.10

Preparing your system

Install pre-requisits

First you need to install the following packages (This is a one line command)

sudo aptitude install perl libnet-ssleay-perl openssl libauthen-pam-perl 
libpam-runtime libio-pty-perl libmd5-perl

Download Main Package

Now download the latest webmin using the following command or from here:

wget http://garr.dl.sourceforge.net/sourceforge/webadmin/webmin_1.441_all.deb

Install Main Package

Now we have webmin_1.441_all.deb package install this package using the following command:

sudo dpkg -i webmin_1.441_all.deb

This will complete the installation. Ubuntu in particular don’t allow logins by the root user by default. However, the user created at system installation time can use sudo to switch to root. Webmin will allow any user who has this sudo capability to login with full root privileges.

Now you need to open your web browser and enter the following 

https://your-server-ip:10000/

Now you should see similar to the following Screen

After login if you want to configure Apache,Mysql server you need to click on Servers on your lefthand side you should many servers are ready to configure

This is very Easy to configure most of the servers and Enjoy your new Ubuntu Intrepid Ibex LAMP Server.

Malware stats on different versions of Windows

Microsoft is making their OS’s more secure

Depending on your background, you may find different sections of the newly published Microsoft Security Intelligence Report (SIR) to be of more interest.  In today’s post, we would like to highlight the section on infection rates based on the operating system (OS) version and the service pack level.  Microsoft has consistently observed that machines with newer OS and with more recent service packs are less likely to be infected by malware.  The graph below shows the number of computers having malware removed per 1,000 executions of the MSRT on that OS/SP during the second half of 2008 (2H08).

In the SIR, you will find the the following conclusions based on this data:

  • The infection rate for Windows Vista is significantly lower than that of its predecessor, Windows XP, in all configurations.
  • Comparing the latest service packs for each version, the infection rate of Windows Vista SP1 is 60.6 percent less than that of Windows XP SP3.
  • Comparing the RTM versions of these operating systems, the infection rate of the RTM version of Windows Vista is 89.1 percent less than that of the RTM version of Windows XP.
  • The infection rate of Windows Server 2008 RTM is 52.6 percent less than that of its predecessor, Windows Server 2003 SP2.
  • The higher the service pack level, the lower the rate of infection. This trend can be observed consistently across client and server operating systems.

There are two reasons for this:

  1. Service packs include all previously released security updates. They can also include additional security features, mitigations, or changes to default settings to protect users.
  2. Users who install service packs generally maintain their computers better than users who do not install service packs and may also be more cautious in the way they browse the Internet, open attachments, and engage in other activities that can open computers to attack.

Server versions of Windows typically display a lower infection rate on average than client versions. Servers tend to have a lower effective attack surface than computers running client operating systems as they are more likely to be used under controlled conditions by trained administrators and to be protected by one or more layers of security. In particular, Windows Server 2003 its successors are hardened against attack in a number of ways, reflecting this difference in usage.
