When I execute,

//server side

/tmp # ./server1

Socket created 

bind done

Waiting for incoming connections....

//client side

/tmp # ./client1

connect failed. Error: Network is unreachable

But I have enabled the network support and drivers in L4Linux configuartion.

Where will the .config file be located, so as to reconfirm if I have enabled correctly? I couldn't find it in l4linux build directory.

Also, I executed packet sniffer on l4linux, which showed

/tmp # ./simplesniffer eth0

Opening device eth0

ERROR: eth0: No such device exists (SIOCGIFHWADDR:No such device)

Thank you L4 community
