The debian version of the software probe runs on a raspberry pi with
raspbian. Any other small device with debian is probably fine as well.

I put a version in the devel branch of the software probe that refers to
a newer version of busybox code, which no longer uses stime. Could you
please try that version and see if it works on Ubuntu?

[atlas] RIPE Atlas Software Probes and Ubuntu 20.04 / glibc 2.31

[Bernd Strehhuber]

Hi Philip,

with newer Linux Dists / glibc Versions (tested on Ubuntu 20.04 LTS)
stime() has been deprecated and replaced with clock_settime().
Busybox got the following commit back in 11/2019:

https://git.busybox.net/busybox/commit/?id=d3539be8f27b8cbfdfee460fe08299158f08bcd9

Compiling on the latest Ubuntu version I applied the attached diff
to get things working again.

Bye
Bernd

[atlas] anchor on a /32 network with on-link routing ?

[Matthieu Herrb]

Hi,

here at Tetaneutral.net we purchased an anchor with the idea to host
it in our network.

For IPv4 We are using /32 addresses everywhere, and do the routing by
setting the 'on-link' flag on the default route.

This configuration doesn't seem to be possible through the management
interface. It complains that the gateway is not no the same network as
the host and provides no way (as far as I can tell) to setup the
'on-link' flag.

Apart from inserting another router in front of our anchor to let it
use a narrower prefix, is there a way to set it up ? Or can this be
considered for the future evolutions of the anchor software ?

Thanks in advance.

I do have a V1 probe at home, since (almost) day 1 and I had another one
dying already, due to the 'ancient' software update which broke a few. So
I'd like to do some contingency planning...

As I do not have a static machine there, just a laptop which goes with me
onto the road, my Q is: what is the cheapest / recommended / smallest piece
of hardware which can support a software probe? Any pointers for more info?

TNX,

[atlas] Q/ if Id 2303 works as expected?

[Schaefer, Henry]

Hi RIPE-Atlas team,

my ripe probe 2303 shows as being up and running, it is connected in a NAT
environment.
The probe does not show data for the Built-Ins (e.g. No data available for
2303 / 1009 for this time period) as well as is not participating in
measurements.

Can you check/confirm that it is not broken or advise what I would need to
do to make it work like other probes please?

Thanks & Regards
Henry Schaefer.
