Re: Local network between l4linux and genode application

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

Hi Stefan,

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

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.

Regards
Stefan
