== Debian HowTo ==

This page will describe the entire installation process of OpenBSC under Debian Linux.

This tutorial is based on Debian Netinstall 5.0 but will work with other Debian versions.

----

To be able to access your OpenBSC machine easily from a remote Terminal, instal ssh.

This can be easily done with "apt-get install ssh".

Because OpenBSC relies on mISDN (named ISDN4Linux before) and hfcmulti as an interface to the BS11, it has to be integrated as a module into the kernel.

First of all you will need to download the 2.6.27.4 Linux kernel from [http://www.kernel.org/pub/linux/kernel/v2.6/].

Change to '''/usr/src/''' on your OpenBSC machine.

Then simplay do a '''wget [http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.27.4.tar.bz2]'''

Unpack the archive:  '''tar -bzip2 -xvf linux-2.6.27.4.tar.bz2'''

and create a symlink to fit the Linux standard conventions: '''ln -s linux-2.6.27.4 linux'''.[[BR]]

Now change to linux-2.6.27.4 typing '''cd linux-2.6.27.4'''.

Download Haralds kernel patch which is needed to change some specific protocol stuff in mISDN:

'''wget [http://bs11-abis.gnumonks.org/trac/browser/trunk/linux-kernel/linux-2.6.27.4-misdn-abis.diff?format=raw]'''

Now rename the file you just downloaded: '''mv linux-2.6.27.4-misdn-abis.diff?format=raw linux-2.6.27.4-misdn-abis.diff'''.

You are ready now to prepare for the main part:

Install some tools needed to build the kernel.

'''apt-get install libncurses5-dev kernel-package'''

Apply Haralds patch to the kernel: 

'''patch -p1 < linux-2.6.27.4-misdn-abis.diff'''

Now configure the kernel modules with '''make menuconfig'''

-not finished yet! will continue soon!
