July 2017 - connman - Ml01.01.Org

by Jeff Gray

I am trying to use NTP in Connman to set the time for my embedded Linux system. NTP is working, but it is not setting the system time. I have read the docs, trying to see what I'm missing, but can't work it out. My domain has an NTP server at 10.16.1.4, which is correctly passed via DHCP. Connman adds the default route as a timeserver, but this is not active. The only service is Ethernet (summarised for brevity): /net/connman/service/ethernet_XXXXXXXXXXXX_cable State = online Ethernet = [ Method=auto, Interface=eth0, Address=XX:XX:XX:XX:XX:XX, MTU=1500 ] IPv4 = [ Method=dhcp, Address=10.16.1.31, Netmask=255.255.255.0, Gateway=10.16.1.254 ] IPv4.Configuration = [ Method=dhcp ] Nameservers = [ 10.16.1.4, 10.16.1.5 ] Timeservers = [ 10.16.1.4, 10.16.1.254] Timeservers.Configuration = [ ] When the connection goes online, NTP does activate: ntp: adjust (jump): +616745865.307993 sec And I can see the internal NTP time using test-clock: TimeUpdates = auto Timeservers = [ ] TimezoneUpdates = auto Time = 883612967 I have enabled debugging for timeserver.c & clock.c, but can't see any errors on the log. How do I get Connman to set the system time? Another question - Timeservers in net.connman.Clock is empty, does this matter? What is the significance of Timeservers defined here versus in a Service? (Just trying to understand how this all fits together)

How to start PacRunner ? Systemd vs dbus auto start

by Julien Massot

Hi all, I'm currently integrating PacRunner, but I don't see any recommended solution to start it. PACRunner ship a dbus autostart file in: /usr/share/dbus-1/system-services/pacrunner.service BTW the path is not correct, I will send a patch to have "org.pacrunner.service". And PacRunner doesn't ship any systemd unit file, so my guess was that ConnMan will start it through dbus if a proxy server is set manually, or if wpad discover a pac/wpad file. But ConnMan plugins doesn't call PacRunner if the daemon is not running, and explicitely ask to not start the daemon. static void destroy_proxy_configuration(void) .. line 237: dbus_message_set_auto_start(msg, FALSE); static void default_service_changed(struct connman_service *service) .. line 267: if (!daemon_running) return; So from my point of view, shipping a systemd unit file is not the best solution, since starting pacrunner on boot is a waste of time. And ConnMan pacrunner plugin, should try to autostart PacRunner if we connect to a network which have a proxy configured or discovered. Last solution should be that on a first call of libproxy pacrunner starts but it look like a bad solution since most likely connman will not send the proxy configuration yet.

Propagate only property changes of the connected BSS

by Jose Blanquicet

Hi, Please read the commit message of the patch before this to get contextualised. An additional reason behind this patch is to resume the discussion about the supported IEEE standards 8021.11. Some time ago, we proposed the idea of add a new Service's property which provides information about the supported IEEE std 802.11 (a, b, g, n, ac, ...) by a WiFi network. At that time, Marcel exposed the reasons why he did not agree about the way we wanted to implement it. Now, after having got more experience on ConnMan we rebuild the idea but the aim of the modification remains the same; we want to add this information in order to provide to the user more precise information about the performances he could achieve and ease him to decide which is the most suitable network, if he can choose. To develop this proposal, we would like to follow what is done for the signal strength, it means to update this new Service property with what the best BSS of the corresponding WiFi network supports. It would make complete sense because at the end, that would be the BSS to which we will connect. Therefore, each time a best BSS is updated because there is another with higher signal strength then the supported IEEE standards will also be updated thus we will always show reliable information. What do you think?

Connman - DHCP client for cellular networks

by Eswaran Vinothkumar (BEG/PJ-IOT-EL)

Hello, I am currently working on an embedded project where we are using TELIT 910 EUG Modem chip. We are using Yocto as the build system. Versions Used: Connman:1.34 and Ofono:1.20 To establish the internet connection I am using the python scripts within the ofono/test directory as follows: /usr/lib/ofono/test/enable-modem /usr/lib/ofono/test/online-modem /usr/lib/ofono/test/set-roaming-allowed /usr/lib/ofono/test/register-auto /usr/lib/ofono/test/enable-gprs /usr/lib/ofono/test/create-internet-context web.vodafone.de vodafone vodafone /activate-context /process-context-settings After this I could see that the device gets the IP address, gateway and nameserver as shown below, ofono_start_gsm.sh[192]: Interface is wwan0 ofono_start_gsm.sh[192]: IP address is 10.249.29.20 ofono_start_gsm.sh[192]: Gateway is 10.249.29.21 ofono_start_gsm.sh[192]: Nameserver is 10.105.144.254 At this point I excepted Connman to connect to the internet but it doesn't. I am seeing the following error message from Connman: connmand[176]: Online check failed for 0x1ce7c80 Vodafone. Also ping and wget didn't work. The output of ip route and /etc/resolv.conf are as follows: route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.166.199.10 0.0.0.0 UG 0 0 0 wwan0 10.105.144.254 10.166.199.10 255.255.255.255 UGH 0 0 0 wwan0 10.166.199.8 0.0.0.0 255.255.255.252 U 0 0 0 wwan0 10.166.199.10 0.0.0.0 255.255.255.255 UH 0 0 0 wwan0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.255 0.0.0.0 255.255.255.255 UH 0 0 0 eth0 cat /etc/resolv-conf.connman # Generated by Connection Manager nameserver ::1 nameserver 127.0.0.1 The contents of ip route and resolv.conf looked strange for me. I looked into Connman documents and the mailing list discussions, it seems like expected behavior from connman. As a test case, I manually started the DHCP client on wwan0. After that I could see that the device is connected to the internet. I checked with ping and wget. Also have downloaded some files to test the internet connection. The output of ip route and /etc/resolv.conf are as follows: route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.166.250.1 0.0.0.0 UG 0 0 0 wwan0 10.166.250.0 0.0.0.0 255.255.255.240 U 0 0 0 wwan0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.255 0.0.0.0 255.255.255.255 UH 0 0 0 eth0 cat /etc/resolv.conf nameserver 10.105.16.254 nameserver 10.105.144.254 I have the following question. Is this the expected behavior? Do I need to run dhclient or missing some configuration in Connman? I have read in the mailing list that the connman has internet DHCP client and running another might cause confusion. After running connmanctl services I could see the connection is listed as AR (Ready state). I expected it to be in AO(online state) *AR Wired ethernet_0001c01df20b_cable *AR Vodafone cellular_204046850339628_context1 I tried disconnecting the service and connecting it back. connmanctl disconnect cellular_204046850339628_context1 --> successfully disconnects the connection connmanctl connect cellular_204046850339628_context1 --> again the connman fails with the message Online check failed for 0x1ce7c80 Vodafone. Running dhclient manually again fixes this issue. I am puzzled about the issue here. Let me know if you need some more log messages. Any help on the topic is appreciated.

Sierra gobi modem and RmNet

by Daryl Nebrich

Hi, I'm using connman 1.34 and ofono 1.20. The modem is a Sierra AR7x series with QC/Gobi. I'm using Sierra's GobiNet and GobiSerial drivers. The drivers use QC's RmNet to expose the cell data connection as an ethernet network interface on the host. Once the modem is setup and online in ofono, I'm able to create the data connection in connman using "connect cellular...". After the connection is established, connmanctl services shows - connmanctl> services *AO Wired ethernet_00049f04434e_cable *AR Wired ethernet_3e75cbee771b_cable c AT&T cellular_310410598635836_context1 The eth1 interface doesn't look to be associated with the cellular service. Eventually, the pending cell service connection times out (service.c:connect_timeout) and the connection is torn down. I attached the log file. Line 53 shows where detect_newlink() appears to setup eth1 as a new ethernet service and doesn't detect it as part of the cellular service. Any ideas how to fix?

Can Pacrunner be used without Javascript?

by Jeff Gray

If my application does not intend to use PAC files & will only use manual mode, is it possible for Pacrunner to work without any Javascript engine? My embedded system has limited resources & I don't want to put a Javascript runtime on there. I have built it in this way & it does connect with Connman, but I can't get it to return anything but DIRECT no matter what proxy settings I use.

Only 1 of those white cards is playable, and the idea that you sandbag a Vial until turn 3 in order to get a token is simply hilarious. The potential in this card lies in agressive sorcery - speed spells. Burn is the first to come to mind (I have half a mind to try to make stoke the flames work in modern), but also strong card advantage engines and tempo plays.

Adding Ad-hoc(ibss) support to connman

by COLIN Tangi

Hello everybody, I need to have ad-hoc support into connman. I have a project that will use B.A.T.M.A.N mesh protocol so i need ad-hoc mode for using it. By doing a small look into source code of connman and its git history i see that ad-hoc network are discard from connman. For example you can look the commit cd9d9e6b485cf730275680d8a4260003b206a1ae Ignore WiFI networks with IBSS (adhoc mode) Do it have some particular reason to discard ad-hoc support from connman ? (Does it conflict with other feature supported by connman for example). And if i start a work to add ad-hoc mode to connman does it have a change to be mainlined ? Every glues to add this support in a proper way are welcome. Best regards, Tangi COLIN

Documentation change request

by Pierre Couderc

Please find here my feeling from a newcomer to connman. First, it works. I have used it during months without having the idea to try to read its doc. So, thank you for it ! But as I have IPV6 problems, so I try to find doc. My first try was to find the README in jessie. This README is empty, so there is a problem for the debian maintainer. Next, google makes me go to https://01.org/connman/documentation which sends me to https://git.kernel.org/pub/scm/network/connman/connman.git/tree/doc that I do not know how to read nor what it is speaking about. and to https://git.kernel.org/pub/scm/network/connman/connman.git/tree/src/main.... which is not usefull I suggest the following small points which would have saved me hours : in fact the main introduction is in https://git.kernel.org/pub/scm/network/connman/connman.git/tree/README I suggest that : 1- a link to https://git.kernel.org/pub/scm/network/connman/connman.git/tree/README is added in https://01.org/connman/documentation 2- a README file containing a single line to link to https://git.kernel.org/pub/scm/network/connman/connman.git/tree/README is added in https://git.kernel.org/pub/scm/network/connman/connman.git/tree/doc (Not all users are specialist git.kernel.org site or of git itself) There is too a problem for debian maintainer : particularly where are configuration file(s) ? I hope to find that in README.debian I have tried to declare this as a documentation bug in |https://01.org/jira/browse/CM| But I am not allowed to connect. PC
