Connman to control OpenVPN connection
by Florent Le Saout
Hello,
I'm trying to get vpn connection managed by connman.
I've been looking in the documentation in the sources or website, but
didn't find my answer yet.
So far, I can connect to my OpenVPN server manually via connmanctl, so I
guess my vpn config file is quite ok.
But the remaining question is about the autoconnection and link
verification.
From my understanding autoconnect, reconnect etc, that we can configure
in main config file only applies to technologies, but VPNs are not
technologies from connman perspectives, so they are listed as service
(maybe my statement here is not correct ?).
My goal is to be able, as soon as I get proper network connection,
either by ethernet, cellular or wifi technologies to get connected to my
vpn server and in case of disconnection (so implicitly a connection
check is done in background) to get reconnected.
* How to setup autoconnect and reconnect with OpenVPN (also in case we
change technology from ethernet to cellular for instance) ?
* Regarding routes, I would like to know how to apply the routes
pushed by the OpenVPN server as the default route?
* Regarding DNS server, I also would like to know how to get the DNS
pushed by the OpenVPN applied in resolv.conf ?
If my questions are unclear feel free to ask.
Below you can find more details about my setup.
Thanks,
Florent.
----------------------------------------------------------------------------
My setup is :
* connman 1.33
* connman-vpnd
* connman-plugin-vpn
* openvpn 2.3.14
My VPN config file is :

Name = OpenVPVN
Description = OepnVPN custom configuration
[provider_openvpn]
Type = OpenVPN
Name = Custom VPN
Host = MY_SERVER_IP

OpenVPN.ConfigFile=/etc/openvpn/client-openvpn.conf
My VPN config stored by connman is :

Connman v1.33 with systemd v230 : experiencing delay in IP assignment
by Shrikant Bobade
Hi,
I am using connman v1.33 along with systemd v230 for yocto based project.
Experiencing delay in IP assignment ranging from 20 sec. to 1.5 min.
While used earlier versions previously didn't faced such delays. So by the
time I am finding the exact change in version causing this delay issue.
Just want to check anyone experiencing such delays in IP assignments.
Any suggestions or pointers will be a great help.
Thanks

[RFC v2] service: Update nameservers and timeservers with changes in IP
by Patrik Flykt
When the IP address changes, nameservers need to be removed and
re-added in order for them to pick up the changed IP address. The
same applies to timeservers, restart the query for those as well.
Reported by Måns Rullgård.
---
Much less messing around with the code if implemented this way.
Can you still test that it works identically to v1?
Cheers,
Patrik

[PATCH] service: Don't auto connect if error is set for service.
by Saurav Babu
In the following scenario:
1. Device gets connected to an AP.
2. Goto AP's settings page and add device's MAC address in block list
3. Device gets disconnected with AP.
4. Auto Connection is again triggered with AP.
In above scenario steps 3 and 4 are repeated infintely even though
device would never connect to AP because it's MAC address is added in
block list of AP.
On the first disconnection connect-failed error is set. This patch only
blocks auto connection whenever an error is set for the service.

two wlan interfaces - tether on one and control the other as a client?
by Matthijs Vader
Hi,
I have two wlan interfaces in linux, from a single rtl8723bu chipset running in concurrent mode. I want to use wlan0 as a normal client, and use wlan1 to host an access point. The idea is to use wlan1 to let users of our blackbox-type-product for setting up eth0 or wlan0 networking and some other config options.
Is it possible make connman enable tethering on wlan1 only, while also still using connman to configure & manage the wlan0 as well to connect to other access points?
All documentation and connmanctl instructions I've seen and use refer to the more generic wifi..
Or won't that work, and would I be therefore better of keeping connman for the client (wlan0) only. So make it ignore wlan1 by blacklisting it, and then setting up hostapd or something similar on wlan1. ?
Best regards, Matthijs

Until 22:35:02 everything goes fine, eth0 interface is up and running.
After three minutes, at 22:38:26 I see some strange logs. What does
(null) mean? Why the interface is removed and then added again? What can
be the cause of the problem?
Thanks in advance for your time

Hidden Wifi with several AP
by Thomas Baron
Hi,
I'm using connman (1.33) on a raspberry pi 3B to connect to a hidden wifi.
While this is working fine there is an strange behavior here : after the
connection is established (using wpa_supplicant), few seconds after connman
switch to another AP which is broadcasting the same SSID (actually there
are several AP on the same network at that place). Once this second
connection is made connman stays connected properly.
The WiFi configuration is set on /var/lib/connman/wifi.config (with Hidden
= true on the relevant service_wifi).
Extract of the relevant logs is below :
Dec 22 08:00:22 connmand[424]: Connection Manager version 1.33

Regarding the signal strengh with iwlist : Quality=36/70 Signal level=-74
dBm for 40:18:B1:0B:65:15 and Quality=46/70 Signal level=-64 dBm
for 00:19:77:3A:D1:54
So is it an expected behavior ? If yes why and is it connman,
wpa_supplicant or the AP which take the decision to switch AP ? Is there a
way to force connman to stay on the first AP and only switch if it doesn't
catch the signal anymore ?
Thanks,
Thomas

[PATCH] service: Block wifi autoconnection when hidden connection is in progress
by Saurav Babu
In the following scenario:
1. Device is connected to AP in non hidden mode.
2. Connection is initated to AP in hidden mode.
connman disconnects old service and tries to connect to new service. But
for connecting hidden service it first scans the hidden AP and when
network is added for hidden AP then connection is tried. In the meantime
normal AP got disconnected and was tried to autoconnect even before
hidden AP was scanned successfully.
Ideally non hidden AP should not be autoconnected when hidden AP connection
is in progress.
This patch blocks wifi autoconnection when hidden connection is in
progress and unblocks autoconnection after hidden connection is started
or hidden wifi scan is completed and hidden AP is not found in the scan list.

I'm build for fedora connman 1.33 and have unexpected disconnects 5-10
times on each day:

[PATCH] openvpn: Close stdout and stderr file descriptor from child on exit
by Daniel Wagner
We only added G_IO_IN to the watch and therefore never got the G_IO_HUP.
That leads to a busy loop because can_read_data always return true.
By adding G_IO_HUP & friends we really termanate now in
can_read_data. But we unrefed the channel one time to much.
These two bugs were introduced by 8e182879f709 ("openvpn: Use proper
logging function")
