Public bug reported:
Binary package hint: network-manager
Ubuntu: 9.04
network-manager: 0.7.1~rc4.1.cf199a964-0ubuntu2
I have recently installed Ubuntu 9.04 on my lenevo T61. I am using a mobile
broadband card (Sierra Wirelss Aircard 880) to connect to the mobile broadband
network.
In Ubuntu 8.04 it was working fine by using the NetworkManager. I only
had to remove the APN setting in the Advanced Settings of the Connection
to get it working. See also attachment nm-ppp-ubuntu8_10.log)
Now in Ubuntu 9.04 - in completely fresh installation - I cannot connect
anymore to my mobile operator. (see attachment nm-ppp-
ubuntu9_04-org.log)
First I guessed that the following warning was the reason for the
problem:
** (process:19537): WARNING **: Could not get secrets: Rejected send message, 7
matched rules; type="method_call", sender=":1.223" (uid=0 pid=19537
comm="/usr/sbin/pppd nodetach lock nodefaultroute debug ")
interface="org.freedesktop.NetworkManager.PPP" member="NeedSecrets" error
name="(unset)" requested_reply=0 destination="org.freedesktop.NetworkManager"
(uid=0 pid=19390 comm="NetworkManager --no-daemon "))
Unable to obtain CHAP password for gprs on UMTS_CHAP_SRVR from plugin
Therefore I was trying to modify the dbus rules for the NetworkManager
in the file /etc/dbus-1/system.d/NetworkManager.conf. I was removing the
following section:
<deny send_destination="org.freedesktop.NetworkManager"
send_interface="org.freedesktop.NetworkManager.PPP"/>
This actually helped to get rid of the above mentioned warning. But still
without success to connect to my mobile operator. In the log files I can now
see that the connection is suddenly aborted in the IPCP negotiaten phase.
Actually, no IPCP Response is received at all. (See attachment
nm-ppp-ubuntu9_04.log). The same actually happend also without the above
mentioned fix of the dbus rules.
My knowledge about the PPP Protocol is very limitted so I do not have
any idea how to go on from this point. So any help is very much
appreciated.
The log files were captured using the procedure described in the wiki
for Network Manager, but with additional PPP debug information.
