Problem starting agent

[hrchhangte]

We see this issue while starting the agent

2016-02-29T14:10:24Z|00002|reconnect|INFO|unix:/var/run/db.sock: connected Configuring OpenvSwitch router.cli:16: 'odinagent :: OdinAgent' input 2 unused Router could not be initialized!

Hi,

The question is that we are using a secondary wireless interface (wlan1 in monitor mode, i.e. mon1) for getting information about the wireless environment, without disrupting ongoing communications.

And we have added this interface to our Click scheme. Therefore, if you start Click without it, it does not work.

We are thinking about a solution for those APs that do not have a secondary interface. Perhaps creating a dummy interface called 'mon1' using kmod-dummy could do the trick. http://unix.stackexchange.com/questions/152331/how-can-i-create-a-virtual-ethernet-interface-on-a-machine-without-a-physical-ad

Thanks. Just want to ask. Which router are you using and which secondary wireless interface are you using for the setup (Hardware)? We always seem to have a problem setting up the network. We would like to replicate the same.

[josemariasaldana]

We are using TP-Link AC1750 v2 routers (Archer C7, which runs with ath9k driver).

And we are connecting an extra WiFi interface: the USB TP-Link TL-WN722N. The datasheet of this device is available here http://www.tplink.com/resources/document/datasheet/TL-WN722N_ds.zip

[hrchhangte]

Thanks. Does the image built for TP-Link AC1750 v2 contains the drivers for USB TP-Link TL-WN722N? Also, we faced issues building the images and click. So, could you let us know which kernel/distribuition/os specific versions you used for building the images and click succesfully.

I have added some information about the dummy interface here: https://github.com/Wi5/odin-wi5/wiki/If-you-don't-have-a-secondary-wireless-interface

And I have also updated the wiki about how to build the .bin file: https://github.com/Wi5/odin-wi5/wiki/Create-OpenWrt-bin-image-including-openvswitch-and-the-ath9k-patch

[hrchhangte]

Thanks for the links. The main problem we are facing is when we run the click agent and let the client connect to the ssid, we have connectivity issues from the client to access point/agent and from client to controller. The issue is there are so many packet losses even for icmp echo request and reply. Could this be a link level connectivity problem between the client and the agent? or a routing issue at the agent?

Could you please share the topology, wireless configuration of access point and network configuration of access point.

Thanks for the info and links.

Hi, we have another problem. The wifi connection (STA and Agent) gets disconnected periodically. From the agent debug messages, it looks like the agent keeps sending deauth frames when association is completed.

Thanks.

[josemariasaldana]

Please try with the Development Branch. We have new improvements there, which are not yet in the Master branch.

[hrchhangte]

Thanks. We followed the instructions for building click. https://github.com/Wi5/odin-wi5/wiki/Cross-compiling-Click-Modular-Router-for-Odin

But we got the same problem/error while building click : BUILDCXX ../../lib/error.cc ../../lib/error.cc: In static member function 'static String .. ...

Which specific linux distro/version are you using to successfully build Click. Thanks in advance.

Hi,

You can try the patch that you can find attached. I hope this will help you to compile Click.

Best,

Ali

Hi,

Still got the problem even after patching. Don't know which one am i missing

Hi, I also faced this problem even adding dummy interface as you recommend @josemariasaldana - I am using TPLink 1043ND v3. Can I run Odin agent without extended wifi card? (If it is required, I will buy it but it will take time)
