Hello !
I wanna add CARP IP balancing support on FreeBSD. My work is
based on
the OpenBSD ip_carp.c diff of 03/18/2007, when mpf added IP
balancing
support.
I already succesfully patch my freebsd to support carpdev,
but mostly like
Ingo F. . Mine is just able to show iface xname under
ifconfig, forcing it
doesn't work, like you said above.
Goog think is carp_input (not the old one renamed as
carp_proto_input
according to OpenBSD) , because my results shown that
multicast data
packets (not the CARP advs, the real packets) never appear
in ether_input
on every other servers.
Several misunderstanding about the input process let me
think to add a right
carp_input (who do an fresh ether_input) but it doesn't work
with my code ;)
Packet just appears on one CARP interface, and never on
others servers/CARP
ifaces.
I am going to test your patch, thanks for it ! Is there
someone who is
working
on IP balancing ? I'll reply here for any additional
information.
Bye list !
