Right. I had old man-pages installed (I think R12B-1, which don't
mention 'raw' but the ubuntu package erlang-manpages gave me R12B-3
which has 'raw').

I was thinking something similar as well. I'm not sure now though - I
would rather not have YXA depend on libc6-dev and linux-libc-dev (or
equivalent) just for this.

Raw socket options are documented in inet[1].

They are available both in libc6-dev (source package glibc), and
linux-libc-dev (source package linux) on my Ubuntu system.
IPPROTO_IPv6 = 41 is located in
* /usr/include/linux/in.h from linux-libc-dev
* /usr/include/netinet/in.h from libc6-dev
and IPV6_V6ONLY = 26 in
* /usr/include/linux/in6.h from linux-libc-dev
* /usr/include/bits/in.h from libc6-dev
And according to RFC 3493[2]:
The declaration for IPPROTO_IPV6, the new IPv6 socket options, and
related constants defined in this section are obtained by including
the header .

Or maybe IPPROTO_IPV6 and IPV6_V6ONLY could be autodetected in
configure.ac?

Can you please comment some on how this works? I can't find
documentation about the {raw, _, _, _} socket option - is it correct
that it is undocumented?
Where does the IPPROTO_IPV6 = 41 and IPV6_V6ONLY = 26 values come from?
Somewhere in the Linux kernel header files I guess, but I would like to
document that somewhere in case Linux changes this sometime in the future.
I'm also thinking that perhaps it is best to put this code in a separate
file, in case this opens up the door to more complex OS depending stuff
in the future...

[Yxa-devel] [patch] Enable IPV6_V6ONLY on IPv6 sockets on Linux
With this patch applied you don't need to enable bindv6only system wide to use IPv6 with Yxa on Linux as described in the README file. Some programs, such as some versions of the SUN Java jre/plug-in, are incompatible with the bindv6only setting, which makes this patch useful when using both Java and Yxa with IPv6 enabled on the same Linux system.
