Hello Alexander,

a libgnutls30 >= 3.5.3-2 triggers, that connman does not start and waits 
the DefaultTimeoutStartSec=90s. With libgnutls30 3.5.2-2 connman is not 
waiting and starts. - I have no indication from journalctl or syslog, 
that connman crashes. D-Bus is running successfully. After the automatic 
"scheduling restart" connman starts without crashing, please see my 
journalctl above. - In [1] ist written, that GnuTLS is used for "WISPr 
hotspot logins" in connman.

I am not sure I understand this one... do you know what the problem is
that triggers the start delay? Does connman crash? Does the dbus
service not come up/respond etc.?

Hi,

this seems to be a feature. Seems you were able to resolve this issue?
Anything you think that should be done here?

Network Manager also has a similar wait job. timeout there is 30
seconds. connman just seem to have a higher default timeout in code
(120 seconds).

You could customize the job with --timeout=30 or we could use that as
the default in the package if we feel there is strong reason to
believe that majority of debian users will want the shorter timeout.

Let me know if you are happy with the ability to tweak by yourself...

Thanks,

 - Alexander


Hi Alexander,

thanks for responding. The problem is twofold. One problem is, that 
connman is buggy with libgnutls30 >= 3.5.3-2. Because of this bug a 
global, default timeout is triggered, located in Debian's 
/etc/systemd/system.conf as "DefaultTimeoutStartSec=90s". This slows 
down *every* boot unnecessary. I was able to resolve this bug only by a 
forced downgrade to 3.5.2-2. This bug should be fixed.


The second aspect is, that I don't use TLS-Tunnels or 
Hotspot-Captive-Portals. A new option in Debian's connmand binary to 
switch off TLS at boottime would be helpful against TLS-related bugs & 
security holes and would give back the control to the user.


Thank you.

Hi,

so NM does enable the wait job by default also? Just timeout
difference? If not I tend to agree that whatever the NM default is
this one should have as well (assuming folks are happy with NM boot
behaviour).

Let me know,

Hello Alexander

NetworkManager don't enable it as default which Connman does.
I think that is what the bug report is about :)

Hi,

this seems to be a feature. Seems you were able to resolve this issue?
Anything you think that should be done here?

Network Manager also has a similar wait job. timeout there is 30
seconds. connman just seem to have a higher default timeout in code
(120 seconds).

You could customize the job with --timeout=30 or we could use that as
the default in the package if we feel there is strong reason to
believe that majority of debian users will want the shorter timeout.
