AGUR12

Hallo zusammen, habt ihr schon das Papier der AGUR12 gelesen? https://www.ige.ch/fileadmin/user_upload/Urheberrecht/d/Schlussbericht_der_… Kapitel 9 enthält Forderungen, z.B.: | In der Schweiz befindliche Access Provider sollen auf behördliche | Anweisung hin in schwerwiegenden Fällen den Zugang zu Webportalen mit | offensichtlich illegalen Quellen über IP- und DNS-Blocking sperren. China wir kommen und zwar nicht, weil wir gefährliche Terroristen jagen, sondern gefährliche Kopierer. Schön auch die Hilfspolizistenaufgaben, wo Provider selbständig nach illegalen Inhalten suchen dürfen. Meinungen? Schöne Grüsse Oli

Anyone round Zurich with an OTDR and a little bit of time?
by Andre Timmermann 04 Dec '13

04 Dec '13

Hi List I'm trying to debug a fiber connection between two datacenters in Zurich. Unfortunately the other companies involved are not very responsive. And please bear with me, I am not a network engineer, I am just the poor guy who got this thingie on his desk... Here is what I am trying to achieve: In each datacenter we got an Arista DCS-7050T-52 with each an SFP 1000BASE-LX which supports up to 10km links on single-mode and 550m on multi-mode fiber. We got a 1Gbps "dedicated Layer2 Connection incl. Managed Switch" from Init7. As far as I know, they are using Sunrise as partner to provide the connection. We are connecting to a SMF with 1310nm. If I put everything together, I still see a "notconnect" on the switchport. Unfortunately the "Platin" support seems to be more like "Bronze", we do not get a proper response right now. Currently I can't tell if there is something wrong within our setup or within the setup of our provider. I would like to get a third party with a proper testing device (and more experience than me) to meet me in the datacenter(s) and help me to find evidence what the heck is going on. Best regards, Andre Timmermann -- local.ch AG Konradstrasse 12/14 CH-8005 Zürich

Broken SPF Check implementation in Microsoft Exchange Forefront?
by Benoit Panizzon 02 Dec '13

02 Dec '13

Hellou Today, I discovered, that emails whose envelope sender matched the DNS SPF record, but whose From: Header did not (like after the envelope sender has being rewritten by SRS) were rejected by a hosted exchange server provider. I got in contact with that admin and he told me that this was the way the SPF check works in the Microsoft Exchange Forefront Server. Well, according to the RFC 4408 only HELO or MAIL FROM are being considered for SPF. Not the From: header. Is there anyone out there who can confirm, that Microsoft Exchange Forefront Server realy has such a broken SPF implementation. Or did the exchange admin just misconfigure his server?
