Hey all
A friend just told me that Cybernet told him there is a Switzerlandwide Internet Problem.
Does anybody know something?

Hi List
If you also noticed emails not being delivered anymore to @bluewin
after uprading to Debian Buster or and other system with newer openSSL
libraries.
This is due to new versions of openSSL not accepting DH keys shorter
than 1024 to counter the logjam attack.
Unfortunately the keys provided by bluewin are too short, causing the
TLS handshake to fail.
Work-Around for now: Disable DH
Test with:
# openssl s_client -cipher 'DEFAULT:!DH' -connect \
mxbw.lb.bluewin.ch:smtp -starttls smtp
…

Hi everyone,
I'm a researcher at UC Berkeley and the International Computer Science
Institute. My colleagues and I are working on evaluating and improving the
accuracy of blacklists. As part of this work, we'd like to hear from you
about the blacklists you currently use, what you perceive as their
strengths and weaknesses, and any thoughts you have on how they might be
improved.
We've prepared an anonymous survey where you can share your views:

Please find the CFP for RIPE 79 below or at:
https://ripe79.ripe.net/submit-topic/cfp/.
The deadline for submissions is
*16 August 2019*.
Please also note that speakers do not receive any extra reduction or funding
towards the meeting fee at the RIPE Meetings. However, on an individual basis,

paragraph in CFP for more information.
Kind regards,
Franziska Lichtblau
RIPE PC Chair

----------------------------------------------------------------------------
Call for Presentations
A RIPE Meeting is an open event where Internet Service
Providers, network
operators and other interested parties get together.
Although the meeting
is mostly technical, it is also a chance for people to
meet and network with
others in their field.
*RIPE 79 will take place from 14-18 October in Rotterdam,
The Netherlands*
The RIPE Programme Committee (PC) is now seeking content
proposals from
the RIPE community for the plenary sessions, BoFs (Birds
of a Feather
sessions), panels, workshops, tutorials and lightning
talks at RIPE 79.
See the full descriptions of the different presentation
formats:
https://ripe79.ripe.net/submit-topic/presentation-forma
ts/
Proposals for plenary sessions, BoFs, panels, workshops
and tutorials must
be submitted for full consideration no later than *16
August 2019*.
Proposals submitted after this date will be considered
depending on the slots
still available in the programme.
The PC is looking for presentations covering the topics of
network
engineering and operations, including but not limited
to:
- IPv6 deployment
- Managing IPv4 scarcity
- Data centre technologies
- Network and DNS operations
- Internet governance and regulatory practices
- Network and routing security
- Content delivery
- Internet peering and mobile data exchange
- Connected Things (aka. Internet of Things - IoT)
_____________________________________________________
Speakers
_____________________________________________________
Presenters, RIPE Working Group Chairs and the RIPE
Programme Committee
are required to cover their own costs to attend a RIPE
Meeting (meeting
ticket, travel and accommodation). We have various ticket
options available
depending on your needs.
Please note that participants can apply for a RIPE
Fellowship or RACI, on an
individual basis, to develop their professional or
academic career.
For more information, please visit:
https://www.ripe.net/participate/ripe/ripe-fellowshiphttps://www.ripe.net/participate/ripe/raci
In extraordinary circumstances, the RIPE Chair can waive
the meeting fee for
presenters. These requests are dealt with on a
case-by-case basis via pc(a)ripe.net.
_____________________________________________________
Submissions
_____________________________________________________
Presenters should be clear on whether they wish to submit
a presentation
for a plenary or working group (WG) session. At present,
most working
groups will solicit policy proposals, discussion points or
other content directly
via their mailing lists. If you’re not sure what kind of
session you should be
presenting at, please visit:
https://ripe79.ripe.net/plenary-or-wg/
RIPE Meeting attendees are quite sensitive to keeping
presentations non-
commercial, and product marketing talks are strongly
discouraged.
Repeated audience feedback shows that the most successful
talks focus on
operational experience, research results, or case studies.
For example,
presenters wishing to describe a commercial solution
should focus on the
underlying technology and should not attempt a product
demonstration.
Presenters should indicate how much time they will
require.
In general, the time allocated for the different
presentation formats is as
follows:
- Plenary presentations: 20-25 minutes presentation with
5-10 minutes discussion
- Tutorials: up to two hours (Monday morning)
- Workshops: one hour (during evening sessions) to two
hours (Monday
morning)
- BoFs: approximately one hour (during evening sessions)
- Lightning talks: 10 minutes in total for both the
presentation and any
discussion
The following general requirements apply:
- Proposals must be submitted using the meeting submission
system,
https://ripe79.ripe.net/submit-topic/
- Lightning talks should also be submitted using the
meeting submission
system (https://ripe79.ripe.net/submit-topic/) and can
be submitted any
time up to and including the meeting week. The allocation
of lightning talks
will be announced on short notice, in some cases on the
same day but often
one day prior to the time slot allocated.
- Presenters who propose a panel or BoF are encouraged to
include speakers
from several (perhaps even competing) companies and/or a
neutral facilitator.
- All presentation proposals will only be considered by
the PC if they contain
at least draft presentation slides (slides may be updated
later on). For
panels, proposals must contain a clear description, as
well as the names of
invited panellists, presenters and moderators.

Except that this is not applicable. In my case my mailserver is not hosted at Swisscom but on my own infrastructure, is on the same IP since years, has proper MX records and reverse DNS entries and has delivered email to the same bluewin customer yesterday successfully. Only the reply on that receiver today which I received and replied again got rejected. And the response is cryptic to me.
And if you mail to abuse(a)bluewin.ch <mailto:abuse@bluewin.ch> you get the same error...
So who …
[View More]is this famous DNSNULL I should contact?
