Is there anyway to get SIM ID?
by JH
Hi,
I am running connman in a 4G LTE device in Linux system, are there
anyway to get SIM ID? and the Operator and LTE signalling strength?
Unfoutuantly, I don't have connmanctl due to the limitation of the
space to install Python.
Thank you.
Kind regards,

[PATCH] timeserver: reload nameservers when service nameservers change
by Vivien Henriet
This is to fix an issue where connman is unable to resolve ntp hostnames.
When a service switch from a autoconf link local address (169.254.0.0/16)
to an address configured by dhcp, timeserver was not notified and thus
was not reloaded its resolver's nameserver. As a consequence, hostnames
of ntp server were not resolved.

The order of a OpenVpn service with topology subnet cannot be changed
due to a missing route
by Thomas Achleitner
Hi,
one of our clients uses a server configuration with topology subnet and
does not push a route from server.
This causes an error when moving the vpn service below the ethernet service
and the default gateway then is the vpn connection.
From the openvpn log i get
Tue Nov 5 09:29:02 2019 SENT CONTROL [test.vpn]: 'PUSH_REQUEST' (status=1)
Tue Nov 5 09:29:02 2019 PUSH: Received control message:

[PATCH] l2tp: Save 'exclusive' config value in lns context
by Jussi Laakkonen
The config value 'exclusive' must be saved in lns context. This is
because if written to lac context parsing will fail (versions 1.3.8 and
1.3.14 were tested):
xl2tpd[]: parse_config: line 12: 'exclusive' not valid in this context
This went undetected unless the option was set. By default, 'exclusive'
is not written to xl2tpd config. The xl2tpd documentation states that
"Most of those described in the LNS section may be used in a LAC
context, where it make common sense (essentially l2tp procotols tuning
flags and authentication / ppp related ones)."
Added a enum option OPT_L2LNS for defining other options to be used in
lns context only.

[PATCH] vpn: Set to use C locale with tasks used for running VPN processes
by Jussi Laakkonen
Set LANG and LC_ALL to C locale for each task used to run VPN processes.
This ensures that no translations are used.
The user for running VPN process can be changed with DACPrivileges
configuration (see commit 171989601a7a4fadafda20a7e6d30e9ada3fb516). If
the user is changed to other than what connman is ran with a specific
language may have been set. Plugins relying on correct output would fail in
such case.
