Thanks to you guys, I now have io-pkt running on my computer.
With io-pkt-v4-hc -d pcnet -p tcpip ad dhcp.client
I was able to create an ethernet interface which allows me to connect ot the internet for instance.
But I'd like to be able to do some ftp and ssh on this ethernet adapter.
How do I do that ?
I tried  io-pkt-v4-hc -d pcnet -p tcpip -p ftp since ftp is a protocol but it does not seem to work.
