Possible spnego licensing problem

2015-02-02 Thread israel shahak
The file spnego.asn1 in lib/dns appears to be non-free. It says to
look at RFC 4178 for the full legal notice and RFC 4178 is under a
non-free license. The file spnego.asn1 is also used to generate other
files.

The contents of the file are taken (adapted) from here:
https://tools.ietf.org/html/rfc4178#page-16

IETF has published RFC 3978 about "IETF Rights in Contributions":
https://tools.ietf.org/html/rfc3978

RFC 3978 is obsoleted by BCP 78, 79 but it was probably current for RFC
4178.

What I had quoted from this is the contributor's grant to IETF, where
"IETF" is described as:

That doesn't exactly mean "general public", so does anyone else know
where a license grant to implementors is documented?

Try adjusting resolver-query-timeout.

That will not help if the FIRST connection is hitting a tar-pit.

(not saying that is happening, but it’s certainly possible)

There is a timeout of at most 9 seconds on queries from BIND's resolver to
upstream servers (which gets adjusted based on measured RTT), and a
configurable overall query timeout (using the above setting) of between 10
and 30 seconds.

BIND w/ Lync?

2015-02-02 Thread Ray Van Dolson
We have a Lync 2013 environment with all of its DNS records living
within our primary domain (esri.com).  I have a need to override all of
the Lync related DNS records so that they resolve differently for a set
of client IP's (clients which connect via VPN).

Unfortunately, the only solution I'm really seeing right now is an ugly
one -- setting up a new view for this set of clients and then creating
25+ zones -- one zone per record I want to override (so that the
primary domain -- esri.com, still gets handled correctly).  Maybe I can
get away with fewer overrides, but right now that's the size of the
list I have.  Even 10-15 isn't pretty from a management standpoint.

Maybe I could somehow do this with RPZ?  Hmm.  We also have some F5's
with the GTM module which I *believe* would let us do some DNS type
overriding, but have never dug into it before.

Using stock Red Hat provided BIND on RHEL 6.x.

Thanks,
Ray
