Severe packet loss Amazon AWS->Telia

[Marian Ďurkovič]

Hi,

we're experiencing severe packet loss for downloads from Amazon AWS via Telia
network, tcpdump regularly shows multiple missing packets triggering SACKs like
this:

08:33:48.935415 IP 147.175.167.x.57668 > 54.231.33.x.443: Flags [.], ack
1051088, win 16384, options [nop,nop,sack 4
{1066840:1068272}{1063976:1065408}{1059680:1062544}{1056816:1058248}], length 0

Any ideas?

Thanks,

   M.

sFlow/NetFlow Weathermap

[Alain Hebert]

    Hi,

    We're looking for suggestion for a "cost effective" sFlow/NetFlow 
solution with dynamic Weathermap for a MAN.


    As the usual most open source solution got grabbed by corporation 
and put behind paywall without much development.


    ntopng seems to be a good candidate we might try it with a site but 
with when your basic interconnect are 40Gb... that ain't gonna fly.


    Thanks.

1. Contact their NOC. amzn-noc-cont...@amazon.com 

2. Provide a traceroute and MTR
3. Provide a pingable source IP

RE: sFlow/NetFlow Weathermap

[Víctor Eduardo Holguín Pérez]

Hi, 

If you want all open source, there are a couple of options:

Cacti + weathermap - native-ish integration
Librenms + weathermap - This one doesn't have netflow/sflow but is based on 
interface's bandwidth (SNMP)
Nfdump + weathermap  - you would have to integrate it yourselves and probably 
use something like ELK stack for dashboards.

Regards,

Víctor Holguín

[CFP] 2nd Asia-Pacific Workshop on Networking (APNet 2018)

[ap net]

**

   CALL FOR PAPERS

   APNet 2018

  The Second Asia-Pacific Workshop on Networking

 Beijing, China, August 2--3, 2018

  *https://conferences.sigcomm.org/events/apnet2018/index.html
*


**

*Overview*



The Second Asia-Pacific Workshop on Networking (APNet’18) aims to bring
together the very best researchers in computer networking and systems
across the Asia-Pacific region and the global community to a live forum
discussing and debating innovative ideas at their early stages. The mission
of APNet is that promising but not-yet-mature ideas can receive timely
feedback from experienced researchers, shaping them into major conferences
such as SIGCOMM, NSDI, SOSP, OSDI, MobiCom, CoNEXT and so on.



*Program Committee*

*General Chairs*

Dan Li (Tsinghua University, China)

K. K. Ramakrishnan (University of California, Riverside, USA)



*PC Co-Chairs*

Mosharaf Chowdhury (University of Michigan, USA)

Kun Tan (Huawei, China)



*Steering Committee*

Suman Banerjee (University of Wisconsin, USA)

Kai Chen (HKUST, Hong Kong SAR), Co-Chair

Albert Greenberg (Microsoft, USA)

Jitu Padhye (Microsoft, USA)

KyoungSoo Park (KAIST, South Korea)

Kun Tan (Huawei, China), Co-Chair

Minlan Yu (Yale University, USA)

Lin Zhong (Rice University, USA)



**

We invite submissions of short papers (up to 6 pages, including references)
on a wide range of networking research, including, but not limited to:

•   Network architectures and algorithms

•   Cloud and wide-area networking systems & infrastructure

•   Networking support for applications

•   Operating system support for networking

•   Kernel-bypass and RDMA networking and applications

•   Enterprise, datacenter, and storage area networks

•   SDN, NFV, and network programming

•   Networking hardware design

•   Network measurement, monitoring, diagnosis, and operations

•   Formal methods and network verification

•   Network security and privacy, censorship, transparency

•   Network, transport, and application-layer protocols

•   Resource management, QoS, and signaling

•   Routing, traffic engineering, switching, and addressing

•   Wireless, mobile, and sensor networking



The APNet Program Committee will select papers based on novelty,
significance, and technical merit, rather than completeness. Innovative
well-reasoned ideas with preliminary evaluations will suffice for APNet.
Accepted papers will be published in the ACM Digital Library. We hope that
the extension of APNet papers, when substantiated by solid implementation
and experimentation, can be published at the aforementioned premier
conferences.



*Important Dates*

Abstract registration:   April 6, 2018 (11:59 GMT)

Paper submission: April 13, 2018 (11:59 PM GMT)

Notification of decision:   June 11, 2018

Anyone else having Tunnelbroker.net issues?

[Brielle Bruns]

Hi all,

I hate asking this on the list, but is anyone else having issues with HE 
and Tunnelbroker.net currently?


Isitdownrightnow.com seems to support the notion there is something 
going on with it, and tests from my various VMs on DigitalOcean in 
various DCs seem to support the notion.

Re: User on list from carid.com sending automated replies

[Valerie Wittkop]

The email address had formally been moderated so replies went to the queue 
rather than automatically to the list.

I had to research - and realized this auto-response falls under the same 
behavior as an automatic vacation message.  The address is now on no-mail 
status per the AUP , number 6.

Cheers,

Valerie

RE: Anyone else having Tunnelbroker.net issues?

[Chuck Church]

I've had problems with my Synology router and tunnel broker for several
days.  Used to work, config didn't change, assigned IPv4 address for me
didn't change, but acting flakey, not much debugging capability on Synology
I can find to figure it out.
