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

Sponsor Presentation / tba | tba (Extreme Networks)
Free Range Routing or how we ditched OSPF for BGP unnumbered (based on RFC5549) | Manuel Schweizer (cloudscale.ch)
As a contributor to the FRR project, I’m going to explain what FRR is and how we at cloudscale.ch are using it. Furthermore, I will shed some light at why we chose a certain x86-based hardware platform and provide a future outlook of where FRR is heading.
Network Unit Testing with SaltStack | Urs Baumann (INS - Institute for Networked Solutions)
Enabling unit testing in the network with Nuts (network unit testing system) and SaltStack. Technical presentation how the open source software Nuts uses SaltStack to test the network.
colt onDemand - from visions in 2012 to reality in 2017 | Andreas Glag (Colt)

Flowmon DDoS Defender | Pavel Minařík (Flowmon)
Flowmon DDoS Defender is a scalable anti-DDoS solution leveraging netflow data from routers or dedicated network probes for real-time detection and automated mitigation of volumetric attacks led against customer’s infrastructure. It provides the state of the art detection with automated mitigation within a minute, deep understanding of attack characteristics and a full-range of methods for successful attack mitigation ranging from alerting (e-mail, syslog, SNMP trap), traffic diversion (PBR, BGP, RTBH, Flowspec), execution of scripts, mitigation in cloud with Scrubbing centres or on-premise through specific out of-band DDoS systems.
if (network == server) { magic happens } | Attilla de Groot (Cumulus Networks)
Automating the network has become common practice. One thing that we don’t want to automate are operator mistakes on a fabric level. How can this be prevented by building a CI/CD environment using Cumulus, NetQ, Ansible and Gitlab.
Introduction to LoRaWAN | Christian Mäder
LoRaWAN is a network stack designed mostly to retrieve data from IoT sensors with limited power source. This talk will be an introduction to how this network stack works; like how it does the addressing and routing or what it's secrecy promises are.
Piranha: where all the fishy routes meet... | Pascal Gloor (Quickline)

Hello List
A Mailserver from a business customer of ours is blacklisted @ bluewin.
The Error Message from Bluewin MXes directing to the removal site:
https://www.swisscom.ch/en/res/hilfe/ip-blacklist.html
Our customer has requested removal via this form, no success.
Our customer has contacted bluewin and opened a trouble ticket. He got
the information that his ISP (us) should take care to remove his IP
from the blacklists, but is not getting any information about which
blacklists.
http://multirbl.valli.org
Blacklisted: 0
We are at a loss. Does anyone know what kind of blacklists bluewin uses?
Kind regards
-Benoît Panizzon-

The point is: if you introduce a change to the packet format (and TLV
would be), you are no longer compatible with IPv4. Which makes the
whole "I want this to be compatible so I do not have to change infra
or end points" totally moot.
Worse, then you have "old IPv4" and "new IPv4" machines who might or
might not be able to talk to each other, depending on which IPv4 address
the "new IPv4" got (a long one or a short one) - while with IPv6, you have
unmodified old IPv4 to ensure compatibility during the transition, and
then you turn it off (in 10 years or so).
---------------------------------------------------
I guess all ways IETF participants thought of a new
address space would not have allowed backwards
compatibility with IPv4?
Thanks for the explanation. I appreciate it.
Hopefully, others here find it interesting, too.

There's no way to make "something with longer addresses" compatible
without IPv4 without changing everything (routers, endpoints) - so,
that argument is usually one brought forward as one of a long list of
standard excuses to avoid deploying IPv6, while at the same time
blaming everyone else for the problems with IPv4.
-------------------------------------------
Note the smiley face above. This one, too... :)
I was not around for those discussions (and not being a computer
science person, nor wanting to go on this for too long as has been
endlessly done on other lists), but it seems TLV would have allowed
4 to be a subset of the new space. I never heard that discussed
much and that's what I meant by my comment.

Yeah, it's quite unfortunate that IPv4 ran out so suddenly,
barely 15 years after people were told to move towards IPv6.
---------------------------------------
Especially after IETF made it backwards compatible and made
it so easy to switch from 4 to 6... ;-)

Hello,
could be someone from swisscom so kind and contact me offlist via email
please.
our customer has a swisscom dsl connection and last week they changed these
to v6.
he already tried 3 times via swisscom helpdesk without success.
the first level seems to have no idea about ds lite and v6... ;-/
we want to go back to v4 native.
in customer center we have deactivated v6 - but it is still online via v6
and ds-lite
we did all what was explained:
- switchoff modem for an hour
- reboot 3 times router etc
effectively now the vpn is for sure not working via ds lite and carrier
grade NAT....
thanks in advance
Stephan
