Hello.
How to make network connection betwen server in l4linux and genode application (for example Arora)? Has Genode implementation for this case?
Hello Ivan,
I'm afraid there is no out-of-the-box solution available by now. But I would think it's not that complicated to extend the nic_bridge to allow clients to communicate with each other. By now, the nic_bridge is held quite simple. It doesn't check the destination of ip-packets from it's clients, just brings them on-line. It only inspects and modifies dhcp requests from the clients (and vice versa).
To reduce work for this task I've attached a modified version of the l4linux run-script, where l4linux and our simple web-server test are started, and communicate with the network via the nic_bridge. With that script I can communicate with the l4linux instance anywhere from my LAN (and vice versa), as well as with the dummy webserver, but both cannot speak to each other. (The run-script requires a pre-configured bridged tap0 device to work properly.)
I hope that brings you a little bit further.
Best regards Stefan

Hello Stefan,
Thank you for script. I tried to use nic_bridge already and got the same result. You've convinced me that this is the right direction and I'll continue to work with nic_bridge.

Hi Ivan,
that sounds promising! I took the liberty to open an new issue for this task:
https://github.com/genodelabs/genode/issues/156
I would love to help you whenever possible, and as far as problems arise.

Hi Stefan,
This simple patch allow me to connect from Arora to web-server in l4linux. Can you check this solution?

Hello Ivan,
thank you very much for your investigation. The patch looks really cute :-). I'll have a deeper look into the nic_bridge again, my first feeling is, it might be wise to check for the ip-destination in the handle_ip method of the tx_handler, too. So that we don't have to send packets to the network in the first place, when it's just for some of the clients, but I'm not sure if I'm right.
Anyway, it's really cool that you dug into the nic_bridge, and found such an easy solution!
Regards Stefan
