NM Cannot connect "wireless broadband": pppd_timed_out(): Looks like pppd didn't initialize our dbus module

[ichudov]

Binary package hint: network-manager

This does not always happen, but it happens MOST of the time, and when it starts happening it never stops happening:

If I use NM to connect to my wireless broadband, it starts pppd and pppd actually connects and gets IP.

However, I see this in /var/log/syslog. After that the connection is terminated.

Any idea?

What is in /etc/dbus-1/system.d/nm-dhcp-client.conf ?

Did you install NM 0.7 from some PPA at some point?

I do not think so, though I cannot be completely certain, as I had Intrepid on this laptop.

I had the same error with Ubuntu Jaunty (rc1) NBR and Nokia N95.

But if I connect the phone before I boot, the connection works. The error appears only if the phone is connected afterwards (with usb cable).

[Alexander Sack (asac)]

sorry. i misread the initial bug. please post your /etc/dbus-1/system.d/NetworkManager.conf .... dbus policy was flipped upside down at some point, so in case you still have the intrepid file, nobody would probably be allowed to call NM ppp.

[Alexander Sack (asac)]

kind of odd. did you modify your /etc/ppp/options or any other ppp related config file at some point?

[ichudov (igor-chudov)]

I do not believe that I modified /etc/ppp/options. I am attaching it.

[João Neves (jneves)]

Could you check if you have related messages in /var/log/auth.log?

Maybe something like:

[Peter Miller (pmiller-opensource)]

I am seeing things like this

when NM is doing this.

I should mention that this is on a clean Jaunty i386 install, kept up-to-date daily.

dupe of bug 371291 - check the "official workaround" in the summary

[AIAMUZZ (muzafsh-113)]

My System : Aspire One ZG5
OS : Ubuntu 10.10 (Maverick)
3G Device : Gobi 2000 (inbuilt)

sorry i seem to have been hit with this bug - a "pppd_timed_out"

The first connection throws up an almost connected log. (Attached File : First 3G connection attempt)

whereas subsequent attempts to connect throws a very minimal log. (Attached File : Second 3G connection attempt)

And i am absolutely unable to connect to the internet.

Please help me fix this issue

thanks

[AIAMUZZ (muzafsh-113)]

a very minimal log on second and subsequent connection attempts !!!

not sure why on second/subsequent attempts the log is not as detailed as the first attempt at connecting after bootup

help most appreciated.

thanks
