Yes, it is not a joke. From Apple site you can learn that Apple won’t develop a new version of XServe. Any order of XServe after January 31, 2011 won’t be accepted.

However, two transition options will be present:

  • Mac Pro with Snow Leopard Server : this solution can surpass in terms of performance XServe.
  • Mac Mini with Snow Leopard : this solution has become the most Interesting Apple’s Server Solution. It is suitable for small business and Workgroups cases. Just one Mac Mini, despite of its small dimension, can offer a so sufficient server solution.

This decision can be justified by these tables :

  • the first table analyses MacPro Performance vs. XServe one:
  • The second table analyses Mac Mini Performance vs. XServe one:
  • The third table shows the different products prices for a standard configuration:

  • Finally, this table presents the different services supported by each product :
  • You can download the XServe transition guide here.

Automatic hosts name resolution technics

January 19, 2011 Leave a comment

In this post, you will discover some well known hosts name resolution technics in a LAN. The purpose is to resolve hosts names without any manual configuration or using a third party solution. This feature is proposed by the zeroconf paradigm.

  • LLMNR (Link Local Multicast Name Resolution): Recently, Microsoft has developed this protocol and integrated it into Windows 2008/2008R2 and Windows Vista/7. The principle is to send multicast (not broadcast) name resolution requests to some machines (which have Networking Discovery feature activated).  This protocol is based on IPv6 but it can  theoretically use IPv4 and send requests to the address.
  • mDNS (Multicast DNS): this protocol is proposed by Apple and aims to provide an automatic name resolution through a decentralized DNS . Each host host its special DNS table with the classical records. With mDNS, a host has the ability to choose any DNS suffix and and announce its new name through a multicast address. The name resolution requests are sent to for IPv4 and ff02::fb for IPv6. mDNS is more used than LLMNR for its compatibility with DNS-SD (DNS based Service Discovery); another Apple product; which aims to facilitate Service Discovery and Announcement. Each host providing services advertises through DNS messages the different information. UPnP is another Microsoft solution but not so wellknown as DNS-SD which is supported by many hardware solutions, some linux distributions and so on.

Mac OS Server is really so wonderful

Mac OS X Server Snow Leopard box.

I have started recently to read some books on Mac OS Snow Leopard Server (10.6) and I have found a great comparison between two solutions for implementing a collaborative solution offering web collaboration and mailing functionalities.

Here is the comparison table (from Snow Leopard Server of Daniel Ergan Dilger) between a Windows based solution and another based on the Mac OS technology :

image XserveApple needs some years to become a real concurrent in the servers world with the big HP, IBM and Dell. Here is an excellent link to have an idea.

Mac OS Server is a complete solution proposing a big number of functionalities : Mail, Web, iChat, iCal, Address Book Server, QuickTime Streaming, etc.

Mac OS Server offers other advanced functionalities (integrated natively) like XGrid to create grids. To create SAN architectures, Apple proposes also XSan (not integrated natively).

I will, inchaaEllah, give details about each wonderful functionality in the coming posts.

Steve Jobs is ill…

According to an article published on Mashabe site, Steve is obliged to take a leave of absence from the company for medical reasons.

Here is the letter sent by Steve to his Apple team:


At my request, the board of directors has granted me a medical leave of absence so I can focus on my health. I will continue as CEO and be involved in major strategic decisions for the company.

I have asked Tim Cook to be responsible for all of Apple’s day to day operations. I have great confidence that Tim and the rest of the executive management team will do a terrific job executing the exciting plans we have in place for 2011.

I love Apple so much and hope to be back as soon as I can. In the meantime, my family and I would deeply appreciate respect for our privacy.


Steve is so important for Apple. When he left Apple company in 2009  the value of a share was below 80$. Today, and thanks to his huge efforts, the value reaches 300$. Consequently, Apple is the second most valuable company in the world.

However, according to the letter, Apple is preparing for us splendid surprises in 2011. New IPhone and IPad and, perhaps, a new other product are not, may be, rumors.

I am not a tuxman, but I have appreciated really the apt-get tool in Ubunto which allowed me to download and install any tool from the APT (Advanced Packaging Tool) store without configuring dependencies or other related installation problems. Other interesting tools also exist like RPM (Red Hat distribution), Yum (Yellow Dog), etc.

In the Mac OS world, if you want to install UNIX applications, you can use MacPorts Line command tool. Nowadays, there are more than 7600 ports (applications). I have discovered this great project when I had to install ettercap tool.

to install ettercap tool for example, you have just to execute the following steps:

  1. synchronise your installation with the macports store : “$ sudo port selfupdate”
  2. install the ettercap tool : “$ sudo port install ettercap-ng”

The MacPorts is available here :
