Since interface names can easily be changed could as well be almost anything, like wifi2 or frobz42. If you deem it appropriate to focus on just one interface, the name should at least be configurable. Or, even better, you could easily pass the IF name as an additional parameter to the backend (and possily even use it as additional component to construct the interface file names). -- Irrwahn ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

As it is now it is build as a one-shot executable run each time an action is required. I thought that was intentional.

An easy way to obtain a list of interface names on Linux is:
awk 'NR>2{gsub(/:/,"");print $1}' /proc/net/dev
For doing this in pure C, by the "rtnetlink" method, please see
attached file, which is based on .

[DNG] replacing kernel 3.16.0-4
I've already tried your patience with a query about why xrandr tells me my display uses VGA 1024x768 when it shows my video card supports DVI 1920x1080. I hope you will bear with me if I pursue the matter. I am told that because selection of optimal resolution is today done by the kernel, my 3.16.0-4 kernel therefore has a bug. I find significant that kernel.org skips this kernel for possible downloading. Is anyone else experiencing this problem? I'm loading fluxbox on devuan-jessie without a desktop environment. When I edit the linux line in the GRUB menu by appending video=VGA-1:d, the display comes up with the proper DVI 1920x1080 resolution. Does this not show that the kernel is sick? So I'd like to use a different kernel, but there are no alternatives in the devuan repository. How then should I install an alternative kernel? Some time ago I tried to install devuan testing and it failed right away for reasons I forget. Is the testing installation option actually working?

Re: [DNG] automount Was: Re: A better default windows manager
If you want a quick hack, I'm using a couple commands in a perl script
kicked off from inittab that works pretty well for listing attached media
with a recognizable filesystem on an appliance I'm working on - its meant
to provide a list of mountable drives but wouldn't take much to perform the
mount since it's running as root anyways.
Source:
#!/usr/bin/perl
while (sleep 10) {
`blkid -c /dev/null > /tmp/dvols.txt`;
`fdisk -l > /tmp/fdl.txt 2> /dev/null`;
}
the blkid gives a nice list of volumes and labels in dvols.txt, fdisk for
the partitions & filesystems.
for mounting everything needed is in the fdisk -l output - I just use the
blkid for presentation information and to exclude my appliance related
drives
Admittedly a crude approach, but it's worked fairly reliably for me.
By directing the output from the fdisk command to an array one could
easily run through the output and mount anything not already mounted.

Or "ls /sys/class/net".
For listing non-loopback devices only, use
ls -d /sys/class/net/*/device | cut -d/ -f5
For wireless, check for the files "phy80211" or "wireless".
The equivalent can be done trivially in C with readdir(); ask if you'd like
an example.

You can compile one yourself:
→ Install the build tools ("build-essential" + "libncurses5-dev")
→ Download kernel from kernel.org or add a source for testing/unstable
and apt-get install linux-source
→ Extract source archive
→ Copy /boot/config-* to ".config" in root of extracted source
→ `make menuconfig` and change stuff if you want
→ `make deb-pkg`, go buy a pizza, return home, install debs from
parent folder :)
But I also think you can directly use a kernel (linux-image-*) from a
newer version of Debian/Devuan... not 100% sure about this though.

I used it with no problems (from a homemade installer image, but using
our official kernel and ramdisk) about 3 weeks ago. Better do an
expert install and select nothing at the "select and install software"
step, as relativaly often a package download fails for random causes
(plus you can easily keep an eye on systemd -installed by default-,
pulseaudio, etc... if you use the aptitude interactive UI)!
