Lwip is a lightweight TCP/IP stack, and a google summer of code made it possible to use lwip to replace pfinet.
The lwip translator provides all of the following:
- Support for IPv4 and IPv6
- Support for TCP and UDP
- Support for multiple Ethernet devices
- Support for fsysopts and command-line parameters configuration
- Support to create an IP tunnel which may be used by an OpenVPN client
To configure lwip for internet connectivity, use the
settrans command, like this:
# settrans -fgap /servers/socket/2 /hurd/lwip ↩
-i /dev/eth0 -a 192.168.0.50 -g 192.168.0.1 -m 255.255.255.0
The argument /server/socket/2 is the node that the translator is to be attached to. This is followed by the translator program to run and any arguments to give it.
There, -i, -a, -g and -m are, quite obviously, the (Mach) device to use, the IP
address, the gateway and netmask. You can discover these values via the
ifconfig command (You need to run this command on the host system and NOT in
the qemu environment).
