 == 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''' 

 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 -not finished yet! 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.
