Subject: Connman very slow to reconnect after every warm reboot
Message-ID: <[email protected]>

Connman 1.35
Linux 4.15.15
x86_64
Systemd 238.76
Been using Connman for 3 to 4 years now. Has always been reliable and stable.
Recently, some annoying issue has crept up: when I (warm) reboot, connman does
not reconnect immediately but lags significantly, is slow to (re)connect, even
after I login to the system.
Previously, Connman would already be on/connected once I logged in. (Referring
to logging in to Linux system via login shell as normal user--Linux Console, no
X, no display manager or DE interference.)
Starting about 2 or 3 versions back, on reboot, it does not connect for some
time--and lags significantly before it finally connects. I can check it with
"ping 8.8.8.8" for example, and I get the usual "Network Unreachable", etc.
It takes time for Connman to come back "up".
I am thinking it "could " be related to the systemd connman.service unit but
not sure; and I see that the seem to be provided upstream not by my distro.
% cat connman.service

I cannot see anythin significant related to Connman in journalctl -b"
Couple of lines from the journal:

file ?/proc/net/pnp?: No such file or directory
Cannot create /var/run/connman/resolv.conf falling back to /etc/resolv.conf
Nothing in dmesg.
I've done the usual searches, and looked at the official docs; and through
recent mailing list archive posts but have not found a solution yet.
I'd appreciate any feedback on how to troubleshoot and resolve this issue.
Please let me know what additional info I may need to provide to help the
troubleshooting.
Thanks

But Ethernet is enabled ... because the secondary interface uses that
technology to connect ... but the first interface doesn't have a cable so
connman didn't recognize it as a service... How can set a static IP to
that interface without using a cable if connman didn't see that interface
as a service? (I explained the use-case.)

You can try to write provision config file, see
https://git.kernel.org/pub/scm/network/connman/connman.git/tree/doc/config-format.txt
for details.

Excellent catch. I changed the commit message slightly, I hope you don't
mind.
Patch applied.

Good idea. Or even random_get_number() would be okay.
