Hello Guys,
I find a statement in session-overview.txt:
"
Multiple per-session routing tables
===================================
.....
By default, ConnMan maintains only one online service. So it is impossible to
send external traffic (routed through a gateway) on multiple interfaces.
In order to enable this functionality, an application needs to issue the
following API calls:
- create multiple sessions, one for each interface to be used
- set each session's AllowedInterface config field to the required interface
name (eth0, eth1, wlan0, ppp0, etc.)
- set each session's SourceIPRule config field to true
- connect each session (or the service it is using)
That will instruct ConnMan to create multiple routing tables, with default
routes in them. After that, the application can issue a bind() call on each
socket, using required interface's source IP address. The bind() call must be
made before a connect() call on a socket.
"
My issue:
I am wondering if my issue is related to this statement.
Now I have two network interfaces: eth0, eth1. They are connected to different
networks.
I observe that by default only eth0 can get IP address from DHCP server. For
eth1, IP is an APIPA address, as below:

Question:
1. For the same type of ethernet interfaces, does connman only maintain one
interface, like eth0?
2. Shall I use session API to enable another interface, like eth1? And
create another route table for eth1?
3. If yes, where can I find the user guide to use session API?
Thank you in advance for your reply.
Best Regards,
Daniel
