What email headers need to be understood by a PGP/MIME enabled email client?
by Benoit Panizzon 16 Feb '18

16 Feb '18

Hello fellow Swinogers To exchange emails containing potentially sensitive customer information with swisscom, we agreed to use PGP encrytped emails. Now when swisscom is sending an encrypted attachment to us, we get those MIME Headers: ------=_Part_5064522_1012233884.1518535424993 Content-Type: application/octet-stream; name=Attachment1.asc Content-Transfer-Encoding: 7bit X-Content-PGP-Universal-Saved-Content-Type: application/pdf; name=Attachment1.asc X-Content-PGP-Universal-Saved-Content-Description: Example_Filename.pdf X-Content-PGP-Universal-Saved-Content-Disposition: attachment; filename=Attachment1.asc; size=143718; creation-date="Tue, 13 Feb 2018 14:56:05 GMT"; modification-date="Tue, 13 Feb 2018 14:56:05 GMT" X-Content-PGP-Universal-Saved-Content-ID: <F73FD4960576014A98D75D430AABA49B(a)swisscom.com> X-Content-PGP-Universal-Saved-Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename=Attachment1.asc -----BEGIN PGP MESSAGE----- Version: OpenPGP totemomail Comment: totemomail OpenPGP - http://www.totemo.com [encrypted content] Well, Neither Claws-Mail nor Firefox with Enigma Plugin do understand those X-Content-PGP Emails which would specify the correct content type and file name and just merely show a binary "Attachment1.asc" attachement. Of course, as experienced user reading the email source, you can save this to disk and then open it with a PDF reader, but using encrypted email should be easier than that :-) So I contacted the totemo support and they told me, that every PGP enabled email client should be able to correctly extract mime-type and filename from the X-Content-PGP Headers. Well I have found: https://www.ietf.org/rfc/rfc4880.txt https://binblog.info/2008/03/12/know-your-pgp-implementation/ Well, I know no clients which support RFC4880 when generating or decoding PGP encrypted emails. How about the SWINOG Community?

RIPE NCC Global IPv6 Deployment Survey
by Massimiliano Stucchi 14 Feb '18

14 Feb '18

Dear colleagues, The RIPE NCC would like to invite you to participate in its Global IPv6 Survey 2018. The goal of the survey is to get an overview IPv6 deployment across the world, and to assess how this is seen from the perspective of ISPs and Enterprise users. The 2018 survey is a follow up to similar surveys run between 2008 and 2013, and will serve as a comparison with the data acquired back then. You can find the survey at the following address: https://www.surveymonkey.com/r/GlobalIPv6survey2018 Responses can be submitted until 31 March 2018. We will then collect the data with the aim of presenting the preliminary results during the upcoming RIPE 76 meeting in Marseille. If you have any question about the survey, please feel free to email us at: ipv6survey2018(a)ripe.net. Thank you very much in advance for your participation! -- Massimiliano Stucchi IPv6 Programme Manager RIPE NCC mstucchi(a)ripe.net Follow us on Twitter for the fastest and latest RIPE NCC Training news! @TrainingRIPENCC

ALLOCATED UNSPECIFIED ranges [RIPE/alloc-unspecified]
by Paolo Moroni 08 Feb '18

08 Feb '18

Good afternoon from AS3303 (Swisscom/IP-Plus). This e-mail is intended as help information for those of you who operate IPv4 PI addresses within the following ranges: 193.5.0.0/16 193.134.0.0/15 193.246.0.0/15 for historical reasons, these ranges used to have a status of ALLOCATED UNSPECIFIED in the RIPE data base and were managed by the ch.unisource LIR (ourselves). In 2016 the RIPE-NCC has received a mandate from the RIPE Address Policy working group to transfer these addresses into standard ALLOCATED PA and ALLOCATED PI addresses, managed by the RIPE-NCC; if interested in the details, please see https://www.ripe.net/ripe/mail/archives/address-policy-wg/2016-October/0118… The transfer of these three ranges has been completed recently. This includes the management responsibility of the related PI assignments, although, for practical reasons, the Swisscom maintainer CH-UNISOURCE-MNT has not been removed from some objects yet. Please find enclosed below the guidelines we received from the RIPE-NCC with respect to the administration of the related RIPE data base objects. Thanks for your attention and understanding, Paolo Moroni IP-Plus Engineering ch.unisource ----------------------------------------------------------------------- Following the re-organisation of ALLOCATED UNSPECIFIED addresses blocks formerly managed by CH-UNISOURCE-MNT, the management of the PI assignments has been transferred to the RIPE-NCC. Each PI assignment will need to have a "Sponsoring LIR" (a RIPE NCC member responsible for maintenance, accuracy and communication with regards to a specific assignment). Please see http://www.ripe.net/ripe/docs/ripe-637#20 for details. Please contact your Sponsoring LIR if you have one. If not, please contact RIPE NCC, <ncc(a)ripe.net>

IPv6 Run Event
by Nico Schottelius 04 Feb '18

04 Feb '18

Good morning Swinog, we are planning our first IPv6 focused event this year. The main topic of the event is, how well the IPv6 deployment of Switzerland has come and to discuss the action points to reach 100% IPv6 coverage. Thus I would like to invite you to join and... ... showcase how and where you enabled sites with IPv6 ... show difficulties and solutions for IPv6 only networks ... meet players from industry to discuss your needs with others ... get a tasty Adler Bräu beer We are at an early planning stage, but wanted to begin to spread the word already (i.e. date to be defined, Website & CfP coming in the next weeks). The format will likely be a 1-2 day event, with talks during the day, discussion in the late afternoon and a networking event in the evening. To decide on the exact format, I would like to ask you to give me a heads up, if you are interested in this event and if you are interested in showcasing something. A simple "+1" or "+1 +talk_about_x" suffices. Depending on the feedback, we will plan for either a 1 or 2 day event. Thanks a lot and have a great snowy Sunday, Nico -- Modern, affordable, Swiss Virtual Machines. Visit www.datacenterlight.ch

datacomm/vtxnet and quicknet/kfsb are missing TLS on their mailservers
by Peter Keel 02 Feb '18

02 Feb '18

Hi I get these errors: | TLS is required, but was not offered by host mx1.datacomm.ch[212.40.2.32] and | TLS is required, but was not offered by host relay.kfsb.ch[213.202.32.8] Since I've made TLS for SMTP mandatory. The respective admins of these servers might want finally at least enable voluntary TLS; some of their customers apparently would like to receive mails from my server. And by the way, RFC 2487 that is referred to for instance in the postfix manpage and stated that one must not make TLS mandatory has been obsoleted by RFC 3207.
