Samba Project Receives Microsoft Protocol Details

Samba software is a free, open source implementation of networking protocols to share files between Windows and UNIX computers. This is a good news for Samba project.

Today the Protocol Freedom Information Foundation (PFIF), a non-profit organization created by the Software Freedom Law Center, signed an agreement with Microsoft to receive the protocol documentation needed to fully interoperate with the Microsoft Windows workgroup server products and to make them available to Free Software projects such as Samba.

Microsoft was required to make this information available to competitors as part of the European Commission March 24th 2004 Decision in the antitrust lawsuit, after losing their appeal against that decision on September 17th 2007.

Andrew Tridgell, creator of Samba, said:

We are very pleased to be able to get access to the technical information necessary to continue to develop Samba as a Free Software project. Although we were disappointed the decision did not address the issue of patent claims over the protocols, it was a great achievement for the European Commission and for enforcement of antitrust laws in Europe. The agreement allows us to keep Samba up to date with recent changes in Microsoft Windows, and also helps other Free Software projects that need to interoperate with Windows

Understanding Linux networking stack ~ from sockets to device drivers

Read from sockets to device drivers Linux networking stack:

One of the greatest features of the Linux operating system is its networking stack. It was initially a derivative of the BSD stack and is well organized with a clean set of interfaces. Its interfaces range from the protocol agnostics, such as the common sockets layer interface or the device layer, to the specific interfaces of the individual networking protocols. This article explores the structure of the Linux networking stack from the perspective of its layers and also examines some of its major structures.
