Hello folks, I have been searching a lot on this topic without finding any solution. I have a bananapi and an edimax ac usb stick. I set it up to be a hotspot a few years back, it was working quite well and I stored an image as backup. To date, I wanted to re-use it but surprisingly, restoring that image on an SD does not produce anymore a working hotspot...this is awful/awesome since nothing has changed in between. This image is running on kernel 4.x (I have read on the forum that on kernel 5.x hotspot has problems) and I have also tried with the latest armbian OS based on kernel 5.x I don't know what to do anymore, since hostapd starts correctly, access point is enabled and up, but not SSID is visible to any device.... Is there someone that had a similar problem? Thanks Gianni

Hi, no my kernel il 4.19.62

Hello guys, I am experiencing such a problem: When I boot my orangepi it starts and it is visible in the router's page view getting IP with dhcp. As soon as I connect over ssh (at least this is the way to trigger it, not sure if it is hapening automatically after a while), the device disappears from the network and it is no more available! I have seen this behaviour happening on 2 different routers. Then I rebooted the device again and in the router config I put the same IP statically linked to the device and I tried to connect over ssh and it worked without disappearing anymore. So it sounds like a bug somewhere using dhcp protocol. Is someone else experienced such problem? How I can help to definitely fix this annoying bug? Thanks, Gianni

Very good!! it is working for me as well

If I run these commands, I get error that modules are in use...how did you do it?

In the detailed steps you can find link to android store for the app...for a video check this out:snapvpn example Basically you use the box as wifi ap and all devices connected to it can use the vpn gateway in trasparente way thus a smarttv over wifi

Hi this is the project I am working on that explains why a PPTP is more than enough (when the vpn server on orange pi is available) for the purpose: snapvpn

Interesting tro know...why the hell it is burning like that?!?!

Yes I know...it is already planned to switch over to a modern vpn protocol...but for my project right now doesn't really matter. Anyway the box will be completely isolated from the internal network and also guests won't see each other.

I think I found something interesting: low consumption how to change the fex: change fex settings

Yeah...I will check what I can do with armbian-config...thanks Not only raspberry...armbian as well on banana pi!

Good to know it...I will then create a second generation Anything about disabling GPU, on board wifi and something else?

Thank you for your reply...this could be a way to disable it, although I prefer to do it in the config.txt if it is possible...anything about disabling the GPU? I want to switch all those off not really for consumption but to reduce the overall heating of the board

Hello guys, soon I will receive this nice toy (512MB) and I want to be prepared for my project: a domestic vpn server (using pptp) serving 1 o 2 guests at most. For this project I just need the RJ45 socket thus I would like to switch off as much as possible (e.g. GPU, on board wifi and others if there). Someone can point me to some resources or list what I can do to accomplish this? P.S. I know that pptp is not as secure as IPSec (and maybe IPSec is heavier for such device) but for the purpose of my project it is enough. Thanks a lot Gianni

I have checked already the other scripts but they are really different from what I have...I have seen many example, who is using the single = who == anyway I tried all combinations...it also has the first line #!/bin/bash that I have just skipped. The strange thing is that not even the first line of code is executed, only when I restart NetworkManager! Thanks for the reply Gianni

Hi all, I am trying to have a script running when eth0 i s up, but it seems that I don't get it. Although I followed a guide and set anything, NM is not triggering my script. So I have created my script without sh extension and called it 90-start-script in /etc/NetworkManager/dispatcher.d: logger -s "I DON'T SEE THIS" if [ "$1" == "eth0" ]; then case "$2" in up) ~/scripts/start_check.sh ;; esac fi; I gave it root ownership, execution flag, but it seems to be not working... I followed this guide: https://wiki.archlinux.org/index.php/NetworkManager#Network_services_with_NetworkManager_dispatcher I am running armbian 5.60 (strech) Thanks

No one has ever tried this?!

Which version of orange Pi has a better chip suitable for being used as stable AP?

Or I am using it in a wrong way or this is really a bug in the system since just putting in the script: logger -s "I DON'T SEE THIS" and switching off interfaces around I don't see it in syslog file. The only time I see that phrase is when I do restart of NetworkManager service.

Thank you so much, although it doesn't seem to trigger my script. This is my script with +x located in dispatcher.d: if [ "$1" == "eth0" ]; then case "$2" in up) ~/scripts/start_check.sh ;; esac fi;

Hello, I wonder how I can perfom this task in armbian in a standard way. Thanks Gianni

Hello there, I finally solved the issue! For sake of information I explain how I solved it: First the required iptables' rules are (these give access to the remote VPN's machines): * -A FORWARD -i wlan0 -o ppp0 -j ACCEPT * -A POSTROUTING -o ppp0 -j MASQUERADE Then to indicate which IP or range of IPs have to have a different route it is required the usage of policy rules: * open /etc/iproute2/rt_tables and put your entry (ID tablename): 100 my_custom_table * ip rule add from 172.24.1.114/32 table my_custom_table (tells to go to another table other than the main one for the source IP 172.x.x.x) * ip route add 172.24.1.0/24 dev wlan0 table my_custom_table (required to receive packets back from ppp0) * ip route add default via 10.10.10.1 dev ppp0 table my_custom_table (routes packet to the VPN's gateway) Make sure Firewall on the VPN server allows incoming traffic from VPN IPs Tha's all!

Ok so the title can confuse more than it really is! So basically I have a armbian distro configured as NAT where wlan0 is the internal interface and eth0 is the "pubic" interface that provides internet (this set is provided out of the box by armbian-config). My devices connect over wlan0 grabbing an IP, say 172.24.1.114 I have added a VPN to a remote network resulting in the creation of ppp0, with IP 10.10.10.12 Having these info, what I want to achieve is: * Only one IP (e.g. 172.24.1.114) has to always go towards ppp0 (that is all traffic back and forth should go to ppp0, so I can either reach machines and navigate on internet with the remote IP) * All other IPs can normally go towards eth0 Starting from the configured NAT from armbian-config I have added the extra iptables rules: -A FORWARD -s 172.24.1.114/32 -i wlan0 -o ppp0 -j ACCEPT (this is before -A FORWARD -i wlan0-o eth0 -j ACCEPT created by armbian-config) -A POSTROUTING -o ppp0 -j MASQUERADE (order shouldn't impact with -A POSTROUTING -o eth0 -j MASQUERADE created by armbian-config) -A FORWARD -i ppp0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT (just to be sure!) These extra rules + the one from armbian-config seem to work all most well: From 172.24.1.114 client I can see content of a remote web server, say http://10.10.10.20 ( so apparently it goes thru ppp0) From 172.24.1.114 client I can navigate on internet, but unfortunately checking the IP I go out with (using a geo ip website), it still results the one from eth0 All other clients correctly navigate going out thru eth0 So to summarize it, I can now reach the remote network over VPN for that IP but it is not able to navigate thru ppp0 Is there someone that can help me with this since I ran out of ideas? Thanks Gio

Sometimes it get stuck...it happend the first time after 2 weeks and now really often every second day...could it be the warm?
