NetworkManager is supposed to handle adding a specific host route for a MessageProxy present in a combined APN. This doesn't appear to be happening anymore in vivid.
I checked krillin/rtm #22/sim1=ATT sim2=empty. With WiFi off, the routing table looks like this: default via 10.186.165.219 dev ccmni0 proto static 66.209.11.32 dev ccmni0 proto static scope link Note, the MessageProxy from the active APN is 'wireless.cingular.com', which is publicly resolvable to...66.209.11.32. With WiFi on, the routing table looks like this: default via 192.168.1.1 dev wlan0 proto static 66.209.11.32 dev ccmni0 proto static scope link 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.8 metric 9 So, when the download manager connects through the proxy, it's data flows over the mobile data interface ( ccmni0 ). When I flash vivid-devel, on the same device, with the same SIM configuration. When WiFi is off, the routing table looks like this: default via 10.177.125.140 dev ccmni0 proto static metric 1024 When WiFi is enabled, it looks like this: default via 192.168.1.1 dev wlan0 proto static metric 1024 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.8 ...which means all traffic goes over the WiFi interface. I've produced similar results on mako/rtm #19/ATT SIM. I haven't yet retried mako/vivid, but I suspect the same problem as with krillin. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1454625 Title: Cannot send MMS messages with combined contexts with WiFi connected Status in network-manager package in Ubuntu: Confirmed Status in ubuntu-download-manager package in Ubuntu: New Bug description: Cannot send MMS messages with combined contexts in case the WiFi is connected, for some operators. Combined contexts are able to handle internet data and MMS data. For the operator for which I've seen the bug, the data is: $ /usr/share/ofono/scripts/list-contexts [ /ril_0 ] [ /ril_0/context1 ] Password = MessageCenter = http://www.pepephone.com Name = MMS Pepephone Username = Protocol = ip Preferred = 0 IPv6.Settings = { } Settings = { } MessageProxy = 10.138.255.43:8080 Type = internet AccessPointName = gprs.pepephone.com Active = 0 Sending an MMS with cellular data and WiFi enabled fails for this operator when using a combined context. Disabling WiFi I was able to send the MMS. The error I see in ~/.cache/upstart/dbus.log is: E0513 09:55:03.254148 4565 file_upload.cpp:345] Upload ID{ d0e5da6eb7664d908ab49b810ff55e01 } http://www.pepephone.com ERROR::Network error UnknownNetworkError: an unknown network-related error was detected The interface that were up when the failure happened were: $ ifconfig rmnet_usb0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.60.155.62 Mask:255.255.255.0 inet6 addr: fe80::8159:5668:797f:eed7/64 Scope:Link UP RUNNING MTU:1500 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:10 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:829 (829.0 B) TX bytes:1052 (1.0 KB) wlan0 Link encap:Ethernet HWaddr 10:68:3f:7a:92:d5 inet addr:192.168.1.40 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::1268:3fff:fe7a:92d5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:355 errors:0 dropped:0 overruns:0 frame:0 TX packets:186 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:51241 (51.2 KB) TX bytes:18951 (18.9 KB) See attached the tcpdump of the packets sent when this happened. Some quick analysis shows that the uploader is sending through the WiFi (192.168.1.40) instead of using 10.60.155.62, so it is clearly a routing problem. The MMS proxy has private address 10.138.255.43 so it is not reachable from WiFi.
