1.) Check with https://www.ict-plus.ch They have a lot experiences with Long reach wifi... 2.) why not just a standard USV? Solar or Wind buffered... or is a normal power supply only sometimes available?

Bluewin.ch SPF record
by Lukas Knauer 09 Aug '18

09 Aug '18

Hello List Anyone from Bluewin reading? We see a lot of seemingly legitimate traffic with envelope sender address in the domain bluewin.ch coming from hosts belonging to Bluewin (reverse DNS record is in domain bluewin.ch). However, these IP addresses are not listed in Bluewin's SPF record. As a result SPF check for sender domain bluewin.ch is not feasible. Is there any particular reason why Bluewin does not list sending servers in the following IP ranges in their SPF record? 195.186.7.0/24 195.186.101.0/24 195.186.121.0/24 195.186.122.0/24 195.186.228.0/24 195.186.123.0/24 (partially listed in SPF record) 195.186.136.0/24 (partially listed in SPF record) (this list is probably not complete...) Best regards Lukas

Battery powered wifi link (20km, multihop)
by Nico Schottelius 08 Aug '18

08 Aug '18

Hey Swinog, does anyone have experiences with long distance (~20km) wifi powered by battery? With have the situation that we basically want to connect Schwanden to Linthal by wifi for at least 12 hours. The idea is to go via several hops, some of them not having any power resource. So my questions to the list are: - What kind of equipment have you used for similar cases or can you recommend? - Are there any battery recommendations? - Other creative ideas on how to get a direct link with >= 100 Mbit/s connectivity? Best, Nico -- Your Swiss, Open Source and IPv6 Virtual Machine. Now on www.datacenterlight.ch.

Hello swinogler I need your help. As part of my master thesis, which I am writing at the Lucerne University of Applied Sciences and Arts in the course Information Security, I am conducting a survey on the topic "Full Cloud Approach - Assessment of information security with focus on SMEs" and would like to find out what attitudes small and medium-sized companies have to this topic and what experiences have already been made. Target group: IT managers, IT security managers and members of management Duration: approx. 10 minutes German: <https://survey.kulhanek.ch/index.php/648676?newtest=Y&lang=de&ID=ao> https://survey.kulhanek.ch/index.php/648676?newtest=Y&lang=de&ID=ao English: https://survey.kulhanek.ch/index.php/648676?newtest=Y <https://survey.kulhanek.ch/index.php/648676?newtest=Y&lang=en&ID=ao> &lang=en&ID=ao Please fill in and share!

SIM Card Hijacking?
by Rainer Duffner 03 Aug '18

03 Aug '18

Hi, saw this article on vice.com mentioned elsewhere: https://motherboard.vice.com/en_us/article/3ky5a5/criminals-recruit-telecom… Does anyone know just how feasible that is in Switzerland? I’m asking from a threat-assessment point of view, not because I want to do it myself ;-) Changing my number from a corporate-managed Orange^wSalt account to another corporate-managed Swisscom account took a number of attempts, IIRC (I wasn’t too involved). Does it make a difference if it’s a private account vs. a corporate-managed account? Though, I guess for the intended purpose (taking over accounts secured with TFA), the change doesn’t need to stay in place for long - just enough to switch the credentials.
