Использование телефона в качестве точки доступа к сети wifi и раздача Интернета¶
This tutorial explains how you get your Ubuntu Touch device online using a USB cable and a computer with internet access. This is useful if there is no available Wi-Fi connection or you don’t have a data subscription on your device.
Шаги¶
Prepare your device (Ubuntu Touch) and your computer:
Turn Developer Mode on in Ubuntu Touch.
Connect your computer to the internet.
Attach your device to your computer via USB.
On the device:
Run:
android-gadget-service enable rndis
Reboot the phone.
On your computer:
Get your RNDIS IP address:
Run:
ip a
Look for an interface named
usb0
in the output:5: usb0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000 link/ether 12:34:56:ab:cd:ef brd ff:ff:ff:ff:ff:ff inet 10.42.0.1/24 brd 10.42.0.255 scope global noprefixroute usb0 valid_lft forever preferred_lft forever
Your IP is:
10.42.0.1
On the device:
Get your RNDIS interface: Run
ip a
31: rndis0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 12:34:56:ab:cd:ef brd ff:ff:ff:ff:ff:ff inet 10.0.0.1/8 brd 10.255.255.255 scope global rndis0 valid_lft forever preferred_lft forever
Your interface is:
rndis0
Change your IP address:
sudo ifconfig rndis0 10.42.0.2
Add your computer as default gateway:
sudo route add default gw 10.42.0.1
Add a nameserver of your choice:
echo "nameserver 1.1.1.1" | sudo tee -a /etc/resolv.conf
Open Morph Browser and test your internet connection!
If it’s not working yet, on your computer:
Turn on IP forwarding:
echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward
Apply NAT:
sudo iptables -t nat -A POSTROUTING -s 10.42.0.0/8 -o eth0 -j MASQUERADE
Make sure you replace
eth0
by the interface that connects your computer to the internet.
NOTE: These steps are usually performed automatically by the NetworkManager on Ubuntu 22.04.
Known Issues¶
The Updates page in the System Settings displays:
Connect to the Internet to check for updates.
After a while Teleports looses its internet connection and must be restarted.
