Had some free time to toy around with Orange Pi Zero
Used a image "Armbian_5.26_Orangepizero_Ubuntu_xenial_dev_4.10.0.img" build with 'compile.sh BRANCH=dev BOARD=orangepizero KERNEL_ONLY=no PROGRESS_DISPLAY=plain RELEASE=xenial BUILD_DESKTOP=no'
- which should not do anything special ?
1) First steps
- run upgrades and normal tweaking (changed hostname, disabled ipv6, changed ntp, changed time-zone, generated correct locale)
2) Ensure that WLAN0 is working as client
- using 'nmtui' created a new connection to my desktop WLAN router
- disabled auto connect from eth0
- reboot with serial connection
- run example speedtest-cli to see that the driver do work
3) Removed the client profile and redo the eth0 for auto connection
4) I used these lines to create the sample profile but them afterwards tweaked it around with nmtui 'edit profile'
nmcli c add type wifi ifname wlan0 con-name ap-wlan0 autoconnect no ssid zmserver nmcli connection modify ap-wlan0 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared nmcli connection modify ap-wlan0 wifi-sec.key-mgmt wpa-psk nmcli connection modify ap-wlan0 wifi-sec.psk "password" nmcli connection up ap-wlan0
Key points here are 802-11-wireless.mode ap and shared
- shared means that network manager creates "internet-connection sharing" like MacOS and Windows wizards
- you cannot give dns-server or any other setting while using the shared - selection
Ensure that the "automatically connect" is selected to make sure that the connection is started when booted
5)
I do have the basic nat lines enabled with 'iptables-persistent'
sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward" iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT
