DAHDI Supported kernel Versions

At the start of April 2025 I was told, in another post, that the lastest version of DAHDI is compatible with kernel version 6.1.0-32:

“The DAHDI drivers were rebuilt in the last week or so – they should be working on latest kernel 6.1.0-32 from Debian 12.10.”

That’s good to know.

But, is there any ‘official’ place where we should look for announcements like this? I looked at dahdi’s github project but didn’t find anything like that.

The source code in the DAHDI GitHub repo is not the same thing as the binary Debian package that Sangoma puts together – probably the latter is what you want since it is what is compiled against specific kernels as released by upstream Debian ie. the same source code can produce multiple different binaries depending on the kernel you are using.

The kernel version information can be found by manually reviewing the file at deb.freepbx.org/freepbx17-prod/dists/bookworm/main/binary-amd64/Packages and searching for the latest & greatest dahdi-linux-kmod-A.B.C-D line eg:

grep '^Package: dahdi-linux-kmod-' Packages

Another option on an existing v17 installation would be to do it like the shell installer does via apt-cache search.

Thanks @penguinpbx ! Both these methods work for me:

[u@h]$ 
[u@h]$ export URL="http://deb.freepbx.org/freepbx17-prod/dists/bookworm/main/binary-amd64/Packages"
[u@h]$ wget -q -O - $URL | grep '^Package: dahdi-linux-kmod-' | tail -1
Package: dahdi-linux-kmod-6.1.0-32
[u@h]$ 

u@h# 
u@h# apt-cache search dahdi | grep -E "^dahdi-linux-kmod-[0-9]" | \
> awk '{print $1}' | awk -F'-' '{print $4"-"$5}' | sort -n | tail -1 
6.1.0-32
u@h# 

Cool :smiling_face_with_sunglasses: Maybe add a “sort” after the “grep” in the “wget” line of method 1 ? Not sure if the Packages file will always be orderly…

@penguinpbx this goes along with the thread here that you have so far ignored. Asterisk sources for FreePBX v17 - #3 by tonyclewis
Where can the community find the source deb packages to verify that whats in the deb package matches the source.
