connman removes FallbackNameservers at startup
Hello, I noticed an issue with FallbackNameservers. When connman starts on system boot it tries to connect to name servers that are specified in FallbackNameservers. But NIC is usually not ready by that moment and connman removes name servers with message: Failed to connect to server 8.8.8.8 So when I run ./list-services script I do not see Nameservers that was specified. -- Regards, Yevhen ___ connman mailing list connman@connman.net https://lists.connman.net/mailman/listinfo/connman
[RFC 4/5] src: Add tmpfiles.d support for resolv.conf
Add tmpfiles.d support for unconditionally creating a symlink from
[/var]/run/connman/resolv.conf to /etc/resolv.conf.
To keep the same behavior as before, the configuration file is
installed to tmpfiles.d. If /etc/resolv.conf behavior needs to be
specified differently by a distribution, do not install the
tmpfiles.d configuration file.

[RFC 0/5] Move resolv.conf to /run/connman
Hi, One of the features asked every now and then is how to keep ConnMan from always writing resolv.conf. This RFC patch set makes ConnMan write its resolv.conf file into [/var]/run/connman and unconditionally set up links by default to this file from /etc/resolv.conf. Patch 3/5 changes ConnMan to create the [/var]/run/connman directory and always write resolv.conf to this location. In order to keep compatibility with previous versions, patch 4/5 implements tmpfiles.d support to unconditionally create the symlink to /etc when using systemd. Likewise, the init script is updated in patch 5/5 with similar functionality, should someone use that startup method. In order to be a bit future-proof, the first patch introduces the $(runstatedir) variable in a compatible manner, as the variable will appear starting with automake 2.70. The two invocations of $(localstatedir)/run are updated to use $(runstatedir) in patch 2/5. Please review and comment, Patrik Patrik Flykt (5): build: Define runstatedir build: Use runstatedir instead of deriving it from localstatedir resolver: Create STATEDIR and use it when writing resolv.conf src: Add tmpfiles.d support for resolv.conf scripts: Handle link to resolv.conf in init script .gitignore | 2 ++ Makefile.am| 21 +++-- configure.ac | 12 m4/configmake.m4 | 15 +++ scripts/connman.in | 4 scripts/connman_resolvconf.conf.in | 1 + src/main.c | 6 ++ src/resolver.c | 2 +- 8 files changed, 56 insertions(+), 7 deletions(-) create mode 100644 m4/configmake.m4 create mode 100644 scripts/connman_resolvconf.conf.in -- 2.1.4 ___ connman mailing list connman@connman.net https://lists.connman.net/mailman/listinfo/connman

Re: ConnMan doesn't clear rfkill softblock when Wi-Fi plugged in after start-up

ConnMan follows the external softblock state. So if something else enabled rfkill on WiFi, ConnMan should have disabled the technology at this point. Please verify the state of WiFi technology at this point. > Now, consider this scenario: > > * ConnMan was not running. > * USB Wi-Fi device is plugged in. > * ConnMan is started. > > In that scenario, ConnMan detects the Wi-Fi technology, enables it, > turns off the rfkill softblock for wlan, and starts tethering. Good! When ConnMan starts it will know that its last technology state for WiFi was 'enabled' and therefore disables rfkill on startup. > Now consider this alternative scenario: > > * ConnMan is running. > * USB Wi-Fi device is plugged in. > > In this scenario, ConnMan detects the Wi-Fi technology, but doesn't > enable it because of the rfkill softblock for wlan. If this starts from the precondition above, we have all of the following events taking place: - ConnMan was started - rfkill enabled for wifi by some external entity - ConnMan updates technology to 'disabled' in response - USB WiFi device plugged in - Nothing happens as the technology is disabled If this is the scenario, please check that WiFi got disabled after rfkill was enabled for WiFi. > In this second scenario, I would wish for ConnMan to turn off the > rfkill softblock for wlan (since it is configured for Wi-Fi enabled > and tethered), and start tethering. What code change would be needed > to achieve that? ConnMan follows external settings of rfkill events, see above.

No. ConnMan will autoconnect a newly detected WiFi only if wifi is a more preferred technology than the already connected ethernet. > If Wi-Fi connects while Ethernet is unplugged, then later Ethernet is > plugged in, then they can both be connected at the same time, which is > good. Yes. Ethernet is more preferred than WiFi, so it will be selected as the interface with the default route. As it is more preferred than WiFi, it will be automatically connected. But as it is ethernet, it's also a bit special. It will always be connected on a cable plug-in as documented in doc/service-api.txt, Connect() method call. > But if Ethernet connects first, and the USB Wi-Fi device is plugged in > later, then it won't auto-connect to the configured Wi-Fi service, and > I wish it would.

That restores the default behavior, which is the order in which the services are sorted - and presented in ServicesChanged() signals - according to connected state, favorite and technology type. With everything being equal, the default sorting based on technologies is in src/service.c, service_compare(), and is ethernet, wifi, cellular, bluetooth, vpn and gadget.
