Hello Alexsander and people,
I am sorry, I post too much emails......
But, I made it work! As Bjørn said, I tried "ifup broadband" and "ifstatus
broadband". And I got :
{
"up": true,
"pending": false,
"available": true,
"autostart": true,
"dynamic": false,
"uptime": 984,
"l3_device": "ppp0",
"proto": "modemmanager",
"updated": [
"addresses",
"routes"
],
"metric": 0,
"dns_metric": 0,
"delegation": true,
"ipv4-address": [
{
"address": "27.165.56.149",
"mask": 32
}
],
"ipv6-address": [
],
"ipv6-prefix": [
],
"ipv6-prefix-assignment": [
],
"route": [
{
"target": "0.0.0.0",
"mask": 0,
"nexthop": "10.64.64.64",
"source": "0.0.0.0\/0"
}
],
"dns-server": [
"223.62.230.7",
"113.217.240.31"
],
"dns-search": [
],
"inactive": {
"ipv4-address": [
],
"ipv6-address": [
],
"route": [
],
"dns-server": [
],
"dns-search": [
]
},
"data": {
}
}
ifconfig shows "ppp0" :
ppp0 Link encap:Point-to-Point Protocol
inet addr:27.165.56.149 P-t-P:10.64.64.64 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:71 errors:0 dropped:0 overruns:0 frame:0
TX packets:82 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:6471 (6.3 KiB) TX bytes:6404 (6.2 KiB)
And ping 8.8.8.8 works!!
Thank you alexander, Bjørn and people in this list!
But there is still problem the interface is ppp0 not wwan0 or something
like this. I will try to figure out this.
Thank you all.
