Support for 2 network interfaces, please test!
Hi,
I hacked together support for two network interfaces. Please test it, if you
can. If you have two network cards recognized by GNU Mach, try this out and
let me know if you can set addresses for both cards, and ping to and fro
both networks. Please try also with and without default gateway )and try
different settings).
If you have only one card, try if it still works for you. Try with the card
and one dummy interface. Again, try different gateway settings.
As I don't have a network card at home, your test would let me know if my
patch is basically correct. It is only meant as a proof of concept, but if
you let me know it works, I will clean it up and expand it to an arbitrary
number of network interfaces! So give it a try, please.
It's available at
http://homepage.ruhr-uni-bochum.de/Marcus.Brinkmann/pfinet.multi.gz
The patch is at
http://homepage.ruhr-uni-bochum.de/Marcus.Brinkmann/pfinet.multi.diff
It's against the CVS version, and also includes the dummy patch.
Examples:
settrans -fg /servers/socket/2 /hurd/pfinet.multi \
-i eth0 -a 192.168.0.1 -m 255.255.255.0
This is a single interface at 192.168.0.1, class C network without gateway.
ping 127.0.0.1 and 192.168.0.1 are local, ping 192.168.0.X goes out (X=2...254)
while everything else has "Network is unreachable"
settrans -fg /servers/socket/2 /hurd/pfinet.multi \
-i eth0 -a 192.168.0.1 -m 255.255.255.0 -g 192.168.0.2
Same as above, but with gateway. Everything else is forwarded to
192.168.0.2 (which hopefully knows what to do).
Those work with the old pfinet as well. Now multiple:
settrans -fg /servers/socket/2 /hurd/pfinet.multi \
-i eth0 192.168.0.1 -m 255.255.255.0 -g 192.168.0.2 \
-i dummy 192.168.1.1 -m 255.255.255.0
Same as above, but with a dummy interface at 192.168.1.1. Everything sent
to 192.168.1.X is lost in the sink. 127.0.0.1, 192.168.0.1, 192.168.1.1
are local.
settrans -fg /servers/socket/2 /hurd/pfinet.multi \
-i eth0 192.168.0.1 -m 255.255.255.0 -g 192.168.0.2 \
-i eth1 192.168.1.1 -m 255.255.255.0
Two networks, two cards, with the gateway in the first network (192.168.0)
please test such a setup, if you can!
I tested two dummy devices, which works. If one or two eth cards don't work,
please attach gdb and see if you can get a backtrace (mail me if you need
help). Even better, fix the problem and let us know what's wrong.
Thanks,
Marcus
