=> there are two levels about the privacy problem: the technical one
which is explained/addressed in the draft (section 4) and worse the
way it can be perceived which is less (or not at all) rational as
the long and silly history of the "privacy extensions for stateless
address autoconfiguration in IPv6" (RFC 3041 and 4941) has shown.

So there is a technical and a "political" argument against the whole
HOST_ID idea. Unfortunately the IETF (and this mailing list) can only
deal with the first one.

Regards

francis.dup...@fdupont.fr

PS: to discuss about the technical point IMHO no HOST_ID proposal brings
a clear advantage. The real issue (address sharing breaks the address ==
identity assumption) has to be solved by the impacted part (i.e., people
should accept this assumption doesn't apply)...

I still deeply dislike the reveal idea but at least the new version has
a decent privacy implication part.
As I don't want to get the IETF associated with names like Amesys or
Blue Coat, I suggest to use only negative recommendations at the
exception of one mechanism so nobody should be able to say we (the IETF)
have recommended such a mechanism.

   None of this is to say it is impossible to add what you suggest.  But

been well understood (cf draft-iab-privacy-considerations)

   To lean on your analogy a little, security discussions often exhibit

   argument that we don't need the sort of operational definition I'm
   talking about.  On the contrary, many of the nastier security

a privacy consideration section which explains the technical impact
and show the IETF doesn't endorse in any way the not-technical aspects

from the issue history.

   statements like yours which talk about a persistent identifier

   HOST_ID does not make the problem any worse than today's

2011-11-15 Thread Francis Dupont
I share your concern about the (or the lack of real) privacy considerations.
I know the IETF is still dominated by people from a country where
privacy is not a fundamental right so can be considered as a side question.
BTW I question if some authors (one lives in the same city than me so
should share my concerns?) intimately believe this whole stuff should
be simply forbidden to preserve the privacy but they don't follow the
right way.

To summarize my position:
 1- I believe this (the devices described in the document) infringes
  my rights as an European citizen (cf European Human Rights) but
  I am not a lawyer so it has to be tested in a court
 2- one is not allow to organize public meetings to discuss how to
  perform clearly illegal actions, in particular from a standardization
  body
 3- as far as I know the legal umbrella of the IETF is the Internet
  Society so I propose suggest if no other way to solve the legal
  issue to sue the Internet Society at the next meeting in Paris in a
  French court on the 1 and 2 basis (e.g., to pay a court bailiff to
  officially see 2...)

 In your previous mail you wrote:

   Is it not true, then, that the better multiplexing ratio disappears
   (while it is often presented as the main advantage of ISP's running
   the NATs instead of CPE's)?
   
=> IMHO this better multiplexing ratio is an illusion: it relies on
a heterogeneous population but this doesn't match what one should get
in the real world: a small number of end-users sharing the same address
and likely living in the same block...
I believe the same thing about the similar argument on the provisioning:
stateful is supposed to make overbooking easier, i.e., you can put a
hard limit L to the number of ports per user with L * <#user> >> <#ports>.
With other words, between BSDs which pre-allocated the swap space when
processes request it, and Linux which kills arbitrary a process when
the swap space is full, you should guess what I prefer...

PS: when applicable stateless solutions are better just because
by definition they are scalable. Exactly the opposite for a CGN.

Re: [Int-area] draft-george-ipv6-required-01.txt --- what about IPsec ?

2011-03-29 Thread Francis Dupont
 In your previous mail you wrote:

   I fear "IPsec required for IPv6" would slow deployment of IPv6.

=> IMHO it doesn't matter as the IETF has *no* way to enforce
such a thing: you can require IPv6 boxes to be blue with red points,
it will have the same effect (other to show it is ridiculous :-).
BTW this was fixed in the requirements for IPv6 nodes and similar
documents.

Re: [Int-area] Last Call: (Logging recommendations for Internet facing servers) to BCP

   Med: To understand the issue, I recommend you the following
   reading: http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt
   
   Med: You can make a quick search on the XFF practices in
   load-balances/proxies to see how it is used for logging purposes.

=> another basic questions: is any of these an IETF blessed protocol?
It doesn't seem to be the case so IMHO these protocols should adapt
to the logging recommendations, not the opposite, and of course
this should be done where these protocols were developed.

Re: [Int-area] Last Call: (Logging recommendations for Internet facing servers) to BCP

 In your previous mail you wrote:

   This is a late comment but I think it is worth raising it.
   
=> as the gen-art reviewer of the document I'd like to
understand the comment.

   This I-D recommends to log the source port number for
   internet-facing servers. But due to the presence of load-balancers
   in the path, the "original" source port may be lost. The source
   port number that will be passed to the target server may not be
   accurate and hence does not meet the initial requirment.
   
=> where are these load-balancers and as they perform a NAT function
why they don't log mappings they create? Or if they are placed in
front of servers why they are not integrated in the logging system?
