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.

are you also seeing more ssh attacks ?
by Tobias Oetiker 04 Jul '18

04 Jul '18

Good Morning are you running an ssh daemon on non standard ports to avoid some of the drive-by-scanning ? we have been doing that for quite some time now with great reduction of scanning noise ... since yesterday this has changed ... we are getting a lot of connection attempts ... are you seeing this too ? is someone actively looking for ssh across the whole port range or is this 'personal' ? cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland www.oetiker.ch tobi(a)oetiker.ch +41 62 775 9902

Cisco 10G Network Modules
by Stefan Brand 03 Jul '18

03 Jul '18

Hi everyone! I'm currently working on a project for a Swiss non profit organisation. They're reworking their network and would need 8 Cisco C3KX-NM-10G network modules for their C3560s, these are, however, on the pricier side for their budget (living the non-profit life). They would also prefer to not go the Ebay route, so: If anyone has some used ones laying around in their cellar we would gladly take them (just send me your price off-list and I'll relay the offer). Cheers, Stefan

GDPR / DSGVO and 'whois' domain data
by Benoit Panizzon 02 Jul '18

02 Jul '18

Dear Swinogers. I run a couple of .com and .ch domains, which are registered via Gandi.net About one week ago, Gandi activated 'privacy protect' on my .com domains, hiding all my contact data in the whois output, without me asking them to do so. They sent an email though, that they would do so because of the GDPR. I asked them how GDPR entitles them to do so, in my opinion the GDPR aims for more transparency and thus, this is contra productive. Also, such domains usually quite quickly get a bad reputation as hiding the whois data is something the 'bad guys' do. Also it becomes a bit more difficult, to verify if a domain is legit or not to decide upon well crafted phishing emails. Or to contact the owner in case of security incidents. I told Gandi about my concerns, but only got the reply that they were forced to hide whois contact information on all domains registered via their service because of GDPR. Having the contact data published now is optional and has to be activated manually by the domain owner. This surely is not the case, as my .ch domains registered with gandi still show my complete contact. So I asked Gandi for how the GDPR exactly forces them to hide their customer's whois data. I haven't got a reply to this yet. So I wonder if somebody on this list knows the background why gandi acts this way and if other registrars do the same. If I get the whois data for some well known domains like: microsoft.com google.com swiss.com credit-suisse.com NONE has 'privacy protect' activated.

emergency connection with a Huawei GSM modem ?
by Per Jessen 13 Jun '18

13 Jun '18

A customer with a flooded telephone cable is trying to re-establish the internet connection over a GSM modem - the mobile operator is Swisscom. He is not getting any inbound traffic, e.g. SMTP on port 25. I was just wondering if this might be blocked? -- Per Jessen, Zürich (19.3°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland.

PTR records with CNAME ?
by Per Jessen 01 Jun '18

01 Jun '18

According to RFC1034 and 2181, a PTR record using a CNAME is not permitted. I believe this to still be correct, postfix certainly doesn't work with a CNAME when it does a reverse lookup. Any comments? thanks. Per -- Per Jessen, Zürich (28.6°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland.
