in a network script, I was wondering if 'it' was waiting for a ipv6 address or so
You may need to disable it in the kernel module, (ipv6.disable=1 or smething like that)
I never had to do that. I replace some networking stuff (router/switch) every seemed to have survived the transition, except 3 RPIs
(it should just get an IP with dhcp/wireless, but somehow it started complaining about wlan0
(I tried to create a new centos image on an SD, but somehow thatdoesn't work. where is the latest working version of it?)
Which image doesn't work? All the latest versions are in http://mirror.centos.org/altarch/7/isos/armhfp/
That is the one for RPI3, right? Does that work on the RPI4 too?
Those are for both, that is why I asked. In fact, in the link there are 3 images that could boot in rpi3 (the generic one, with a normal kernel, the rpi-minimal, with kernel from rpi foundation, and the rpi-minimal-4 which also works on the raspberrypi4)
good to know, I wondered what the differences are
is there a way to fix this wlan0 error ?
That depends on how ipv6 is disabled, but even so, that looks more like a warning than an actual error.
That's what I thought, just wondering if it actually is.
Since you're not actually using ipv6, you can ignore it
right, on "regular machines" when configuring network stuff, I disable it
thanks,
