Hi Pao, Thanks for your reply.
I did try running the "modem-netns-setup.py" script which makes the modems invisible to ofono as expected. Deleting the namespaces then restarting the ofono service makes them reappear. I've watched your talk and read the accompanying slide deck, and you mentioned a patch being put in place that works around this removal issue - do you have details of this patch so we can apply it and try? This removal issue also seems to be talked about in https://osmocom.org/issues/3881 when modems crash, which happens frequently. https://github.com/osmocom/osmo-gsm-tester/blob/b172c066fb73e0156f9be2f024ae625e31f39abc/src/osmo_gsm_tester/obj/ms_ofono.py#L694 also seems to deal with moving modem interfaces into network namespaces, and following this example https://github.com/osmocom/osmo-gsm-tester/blob/master/sysmocom/suites/gprs/ping.py I tried adding the calls to "activate_context" and "setup_context_data_plane" to our 4G ping test script, which crashed out with an error "GDBus.Error:org.ofono.Error.NotAttached: GPRS is not attached (36)". Best, Callum.
