I have monitored calls to ofono DBus connection manager interfaces following comment #7 in
https://bugs.launchpad.net/ubuntu/+source/telepathy-ofono/+bug/1226739 The command was: # dbus-monitor --system "interface=org.ofono.ConnectionManager" "interface=org.ofono.ConnectionContext" I have attached the output. What I see is that a process with unique name ":1.8" is activating/deactivating periodically the cellular data context. # dbus-send --system --print-reply --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.GetConnectionUnixProcessID string:":1.8" showed the PID of NetworkManager. The output of /usr/share/ofono/scripts/monitor-ofono is: ... {ConnectionContext} [/ril_0/context1] Settings = {} {ConnectionContext} [/ril_0/context1] Active = False {ConnectionContext} [/ril_0/context1] Settings = { Interface = ccmni0, Gateway = 10.79.188.18, DomainNameServers = 212.166.210.82 212.73.32.67, Netmask = 255.255.255.0, Method = static, Address = 10.79.188.18 } {ConnectionContext} [/ril_0/context1] Active = True {ConnectionContext} [/ril_0/context1] Settings = {} {ConnectionContext} [/ril_0/context1] Active = False {ConnectionContext} [/ril_0/context1] Settings = { Interface = ccmni0, Gateway = 10.143.31.135, DomainNameServers = 212.166.210.82 212.73.32.67, Netmask = 255.255.255.0, Method = static, Address = 10.143.31.135 } ... ofono is just told to activate/deactivate the context, no spurious disconnections happen.
