To the Linux folks having problems, please check out
www.linux-ipv6.org . This is home
of the USAGI project (part of WIDE project in Japan, headed by Dr. Jun
Murai). Following
this is the description of USAGI from this site.
Note that WIDE also does the KAME IPv6 stack, which is included by
default in *BSD.
It is the best and most complete IPv6 I have run across. USAGI is an
attempt to provide
the same basic functionality for Linux, although they seem to run a
bit behind KAME.
To those who don't speak Japanese, you may be interested to learn that
Kame means
"turtle", and Usagi means "hare". I fyou know your Aesop, you will
understand why
the "turtle" is ahead in this race. ;-) The expansion of USAGI as an
acronym is
clearly an after-the-fact rationalization, and would make it USAGIP
anyway.
If it is an option for you, we have found by experience that FreeBSD &
OpenBSD are
better and more complete for IPv6 work than Linux as is, or even Linux
with USAGI
stack. Please no flames from Linux fans! The KAME stack is recognized
worldwide
as the reference implementation of IPv6, and WIDE has done an amazing
amount of
really quality work on it, and I am stating this as my opinion, based
on research and
testing.
If your Linux distro happens to already include the USAGI stack, you
can ignore this
message. Any real Linux gurus out there - do you know of any distros
that do include
USAGI by default? If not, any experience using the Linux stack as is,
or the USAGI
stack? If it USAGI is not already included by default, perhaps you can
encourage
your favorite distro to include it?
Description from USAGI site follows:
Currently we have an IPv6 implementation in Linux kernel source tree.
Only enabling "Internet Protocol Version 6" option in the Networking
section, we can enjoy IPv6 life.
However, once you begin to use IPv6 on Linux box, you will soon be
aware that the implementation have some problems... Because an
existing Linux implementation is too old and not so well-tested, it
has many bugs and unimplemented functions.
Then we decided to start USAGI Project(UniverSAl playGround for Ipv6
Project) with WIDE Project, KAME Project and TAHI Project. The project
aim to improve IPv6 environment on Linux and deploy the IPv6 Internet
on the world. We've started to hack the kernel, libraries and
applications aggressively and will provide our product freely for
Linux and IPv6 community. In the near future we would contribute and
merge our code into the main trunks of Linux kernel and glibc.
Because of the contribution for main trunks, we have a policy that we
don't make and accept changes which depend on Linux distributions.
Instead the policy, we will provide binary packages for Linux
distributions on every stable release. Let's try out USAGI IPv6
environment with us !!

Subject: Trouble with 2.6.11 Linux
Hello,
I have a 2.6.5 Linux running router radvd.
I also have 2.6.5 clients(and a 2.4.20 client) that accept the router
advertisements from the router and acquire a Link-Global address and
also autoconfigures their Link-Local address.
Their configs:
ipv6.conf.eth0.accept_ra=1
ipv6.conf.all.accept_ra=1
ipv6.conf.default.accept_ra=1
I have a 2.6.11 client host that does not accept any router
advertisements even though it's config is the same as above. (I have
compared the "sysctl -a" output on both the 2.6.5 and 2.6.11 and they
are identical). In fact the following is what occurs at boot time:
1. When I boot up this client, eth0 does not have the inet6
Link-local address.
If I then issue:
ifconfig eth0 down
ifconfig eth0 up
The inet6 Link-local address then appears.
2. My 2.6.11 host does not learn this prefix and as a result there is
no Link-Global address.
Has anyone experienced this issue.
Thank you,
Phil Bellino
