Hi @IgorSo is it a bug I am seeing and not a setup issue?

Hi all. I installed the latest Armbian on a OPI PC Plus that I have. I want remote desktop and console Desktop. As soon as I install tightvnc the console desktop wont login anymore. I get a pasword box and as soon as I enter it the screen will go black and then reset back to the login box. How do I set it up so I can have remote desktop and console desktop. I tried to install remote desktop for Windows RDP also and that also does not work.

I compiled the tools but when I run it I get this error. ERROR: Allwinner USB FEL device not found! Not sure how to use that tool?

Anybody ??

Hi. I need the serial number of the CPU of the orange Pi boards. I see it is in the file /proc/cpuinfo I need another place that is not file based as the cpuinfo file can be spoofed. Is there a way to read it directly from a register?

OK I see now. Yep it is enabled. I will disable it and see if they stay up now.

Hi thanks for the reply. All the boards reboot +- at the same time. Its not power. What am I looking at in that folder ?

Hi all. I am not sure but it seems that all my Orange Pi boards will reboot by itself. I assume it is a setting some-ware as I see in the syslog something about unattended upgrades. If it is a setting where can I switch that off ? Regards.

Dude you are 100% correct. I never knew this. You are not allowed to have the interfaces on the same subnet. What I did was replace the static ip of eth0 to dhcp and left the cable unplugged and then the wifi came up and now all is working 100%. Thank you for the help .

I got it working using this configuration. The wifi client and AP links will work 100% if the eth0 lan cable is plugged in. I can get to the 10.64.9.0 subnet from a mobile device connected to the AP. But as soon as I unplug the eth0 cable the client wifi link will be inaccessible. I can no longer get to 10.64.9.77 from the 10.64.9.0 subnet. but I can still get to it from the AP side I dont need both to work at the same time. I ca use the cable for that while testing but if it works with the cable why does it not work with 2 wifi links ? This statement seems to enable the fact that I can get to the Pi content without having to bridge the 2 adapters iptables -t nat -A POSTROUTING -s 172.24.1.0/24 ! -d 172.24.1.0/24 -j MASQUERADE Interfaces config file auto lo # bro auto eth0 auto wlan0 auto wlan1 iface eth0 inet static address 10.64.9.78 netmask 255.255.255.0 network 10.64.9.0 broadcast 10.64.9.255 gateway 10.64.9.20 iface lo inet loopback allow-hotplug wlan0 allow-hotplug wlan1 allow-hotplug wlan0 iface wlan0 inet static address 172.24.1.1 netmask 255.255.255.0 network 172.24.1.0 broadcast 172.24.1.255 iface wlan1 inet static address 10.64.9.77 netmask 255.255.255.0 network 10.64.9.0 broadcast 10.64.9.255 gateway 10.64.9.20 wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf /etc/dnsmasq.conf interface=wlan0 # Use interface wlan0 listen-address=172.24.1.1 # Explicitly specify the address to listen on bind-interfaces # Bind to the interface to make sure we aren't sending $ server=8.8.8.8 # Forward DNS requests to Google DNS domain-needed # Don't forward short names bogus-priv # Never forward addresses in the non-routed address $ dhcp-range=172.24.1.50,172.24.1.150,12h # Assign IP addresses between 172.24.1.50 and 172.24.1.150 with $

I got it working to a point. I can have it in AP mode and have everything working from the Pi. Or I can have it in client mode. But not both at the same time. Probably have to sort out some IP routing. But I am making progress. I don't need it to be both at the same time. I just want to see if I can get it to work that way.

Why ? I have been using multiple wifi connections for years. If the one fails the other takes its place. But in this case I will have only one. Please explain why you state that. Regards.

I got some other questions now. Will play with it and let you know. So it seems I am missing the bridge part in my config if I look at what the tool is doing. As I stated only one of the 2 wifi links will be active. If there is a wifi network then the pi will connect to it via the client link and the user will connect to the same wifi network and interact with the web interface. If there is no wifi network then the user should be able to connect to the Pi AP and get an ip address. Then the user should be able to navigate to the same web page to interact with the web interface.

I tried that first but I could not get it to be both AP and Client at the same time. I could set-up a AP only or a client only. How do I set-up one wifi link as hotspot and the other as client with this tool as when I tried it it would say the wifi is in use it will remove it.

OK so here is my Interfaces file auto lo auto eth0 auto wlan0 auto wlan1 iface eth0 inet dhcp iface lo inet loopback allow-hotplug wlan0 allow-hotplug wlan1 iface wlan0 inet static address 10.64.9.1 netmask 255.255.255.0 network 10.64.9.0 iface wlan1 inet static address 10.64.9.77 netmask 255.255.255.0 network 10.64.9.0 broadcast 10.64.9.255 gateway 10.64.9.20 wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf Here is my /etc/hostapd.conf file ssid=OPi interface=wlan0 hw_mode=g channel=7 #bridge=br0 driver=nl80211 logger_syslog=0 logger_syslog_level=0 wmm_enabled=1 ieee80211n=1 wpa=2 preamble=1 #wpa_psk=66eb31d2b48d19ba216f2e50c6831ee11be98e2fa3a8075e30b866f4a5ccda27 wpa_passphrase=12345678 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP auth_algs=1 macaddr_acl=0 noscan=1 Here is my /etc/dnsmasq.conf file interface=wlan0 no-dhcp-interface=wlan1 bind-interfaces server=8.8.8.8 domain-needed bogus-priv dhcp-range=10.64.9.150,10.64.9.200,12h I can connect to the Pi AP and I get an IP. That all works fine. But I can not get to the web page running on 10.64.9.77 or 10.64.9.1 I can ping from the Pi to the mobile devices if I use wlan0 as interface but not the other way around.

Hi all. I followed this tutorial and I got the AP and client mode working. wlan0 using the onboard wifi as the AP and wlan1 using a usb dongle as the client connecting to my wifi network. But when I connect to the PI and got an IP address via dnsmasq I am not able to get to the pi its self. I can not access anything on the PI. I have a web server running on it. How do I get to the services on the Pi it self via the AP I created. Basically what I want to do is have the client connect to the wifi network if there is one or if the pi is in range of the wifi network. But then if there is no network then I want to connect to the AP from my phone and still get to the web interface running on the Pi. I am able to ping my iphone from the pi if I use wlan0 as the interface (the AP wifi adapter). So the AP part is working. I think I have a config issue someware. Hope somebody can help me.
