== 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, install 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/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'''
Include the ''mISDN'' modules and ''hfcmulti /hfc e1 drivers''.
Save the new configuration to '''.config''' .
You can now try to build the Debian kernel package: '''make-kpkg linux-image --initrd --revision=openbsc01.0''' .
Go a directory higher (cd ..)
and install the new kernel package typing:
'''dpkg -i kernelpackagename.deb'''
Now you only have to add the dslot=1 parameter for hfcmulti to load with this parameter.
Otherwise OpenBSC will talk on signalling timeslot 15 where BS11 uses 1.
Simply add the following in '''/boot/grub/menu.lst''' :
Add this line to the "Kernel"-line
'''hfcmulti.dslot=1'''
Save changes and reboot your machine with your new kernel.

''Congratulation, OpenBSC should run fine now!''
Note: You sould install the following debian packages before you start:
* libdbi0
* libdib0-dev
* libdbd-sqlite
* autoconf
