Subject: IPv6 unique local address flushes on up/down
Date: Tue, 25 Mar 2008 15:57:21 +0100 [thread overview]
Message-ID: <200803251557.21563.chunkeey@web.de> (raw)
Hi,
I have a problem with hostapd & IPv6...
as you might know, or not... hostapd needs to initialize
the interface (e.g it changes it to master/accesspoint mode,
which can only be done if the interface is down)...
However if the interface is brought down & up again (e.g whenever
hostap starts or restarts)... the IPv6 logic flushes the unique-local ipv6
address that I gave it (by hand) with ip addr add fddb:xyz...::1//64 dev ath0
in /etc/network/interfaces ifup script (-probably debian specific-).
And that's bad, because bind9,ISC dhcp-server v4.1 and racoon(IPsec/VPN)
needs a static address for their records/lease database and configuration...
This wasn't problem with the old IPv4... because there the
10.x.y.z or 192.168.a.b addresses aren't deleted when the interface
was _reinitialized_ by the hostap...
Now my question, which _one_ should we fix the applications or the stack?!
I think the network stack, but I don't know if there are RFC about this
issue... or is there already some flag/setting which I've missed so far?
Regards,
Christian
