There are different ways, depending on your kernel. Unless you are an
experienced user of Linux, you should use a recent kernel (=first option).
- You have a recent kernel (at least 2.0.36/2.2.11/2.3.14):
Great choice, you have already the current kernel ISDN stuff.
Additionally, you just need to get the current isdn4k-utils package from
ftp://ftp.isdn4linux.de/pub/isdn4linux/utils/ - unless it's already
included in your distribution.
- You have an older kernel (before 2.0.36/2.2.11/2.3.14):
An upgrade to a recent kernel is HIGHLY recommended. And it is MUCH easier
to do a kernel upgrade than to get ISDN to work with your older kernel.
Ok, now if you still want to keep your old kernel, here is how to do it:
First you have to identify the correct CVS extract for your kernel version
(CVS is the version control system the ISDN developers use to develop
ISDN4LINUX). Take a CVS snapshot that is dated with about the date when your
kernel came out. You find the kernel patches and the old isdn4k-utils packages
or on one of its mirrors

- As a developer:
If you want to participate in the development of i4l, you can get the very
latest stuff via CVS. For this, see the question about access to CVS:
CVS - Concurrent Version System:
This is a multiuser/server extension to RCS (Revision Control System).
The I4L drivers are developed under CVS, and there is a server
(cvs.isdn4linux.de) with a CVS tree to which all developers have
access. In addition, Fritz has configured anonymous read-only access
to the CVS tree . If you must have the very latest versions, you can
get them there, however they may contain more bugs than the released
Here is how to get the latest version:
- Create and go to the directory where you want to store i4l
mkdir ~/cvs; cd ~/cvs
cvs -d :pserver:email@example.com:/i4ldev login
- Log in (asks for a password, enter readonly)
- Get the isdn kernel driver stuff (same hierarchy as in the linux source)
cvs -d :pserver:firstname.lastname@example.org:/i4ldev checkout isdn
- Get the utility package into the current directory
cvs -d :pserver:email@example.com:/i4ldev checkout isdn4k-utils
If you want to get the latest version for kernel 2.0.x rather than for the
latest kernel, then you have to give the additional option `-r':
cvs -d :pserver:firstname.lastname@example.org:/i4ldev checkout -r isdn4kernel_2_0 isdn
- After having checked out, further updates can be done by first
isdn4k-utils subdirectory and
cvs update -P -d
Tip: since cvs stores the password on your first login, you don't need to login
again when updating.
WARNING!! THE NEWEST STUFF SOMETIMES IS VERY INSTABLE OR MAY NOT EVEN
COMPILE WITHOUT PROGRAMMING KNOWLEDGE -
No newbie questions on this PLEASE! Use the source, Luke!
