Pro / Contra Backup MX?
by Benoit Panizzon 31 Aug '12

31 Aug '12

Heya Swinog We have business customers with an own mailservers asking us to provide a backup MX for their mailserver. Usualy we deny such request, because such a backup MX would bounce all spam which cannot be relayed, and anyway, the sending server usualy queues the email usualy about the same amount of time a backup mx would queue it. So we see not advantage, but a big disatvantage. Now some of our customers complain that 'all other ISP' offers such services. So I wanted to know your opinions: - Why would business customers _need_ their ISP to operate a backup MX for them? - Why can you avoid the disatvantage to generate a shitload of bounces when operating ab backup MX? - Is it true, that most ISP offer this kind of service?

MS DNS creating invalid records rejected by Bind check-names?
by Benoit Panizzon 30 Aug '12

30 Aug '12

Hello World! We have a strange problem with a customer for which we provide secondary DNS services. He uses a Microsoft DNS Server. According to the RFC I found, the underscore character is only valid in SRV Records. In any other records, this is an invalid character. Our Customers ADS Server keeps autocreating one records like this: gc._msdcs.web.EXAMPLE.COM 1800 IN A 192.0.2.44 Bind refuses to accept zone transfers from his server and eventualy the zone expires on the secondary. Then the customer deletes the RR, the transfer is successfull, but shortly afterwards the mentioned A record with underscore is re-created by the ADS and the problem is back. Is this some kind of MS DNS bug, or have the DNS RFCs been updated recently to also allow underscores in other RR and some non bleading edge versions of bind still use the check from previous rfc?

Bluewin DNS does not resolve domainhost.ch
by Daniel Kradolfer 27 Aug '12

27 Aug '12

Hi, anyone of the bluewin nameservers does resolve domainhost.ch. i didn't found any reason for this. Switch says that all settings are ok. Any other nameserver i tried resolves domainhost.ch correctly... Can someone of bluewin have a look at this issue? Our clients aren't really happy, that they can't resolve domainnames on our nameservers. -- Freundliche Grüsse */Daniel Kradolfer/* ml(a)smilesolutions.ch <mailto:ml@smilesolutions.ch>

BOFh - Richard from the Shadowserver Foundation in Berne
by Adrian Wiesmann 23 Aug '12

23 Aug '12

Hi there Richard, one of the directors of the Shadowserver Foundation, will be in Berne for a few days. Since that sounds like a great opportunity to meet Richard and to learn more about Shadowserver (and to have another beer), I am organising a "Beer on Friday, hellyes (BOFh)" in the evening of Friday the 31st of August in Berne If you are interested in joining the fun, please drop me a note. I will then try to find a place with enough space and let you know when and where you can find us. If you are quick I also still take suggestions on where you think we should head to. I know this is on short notice, but if there is enough interest, we could do some session(s) during Friday and then together head to the BOFh. For that we would need a room somewhere in the center of Berne. Richard could give a presentation introducing Shadowserver and we could then go from there with what they do, what you have that they need and what they offer in return. Just an idea... Looking forward to your feedback and comments. Cheers, Adrian

Re: [swinog] [swinog-antispam] Calling all stations!

Dear Viktor, 1. I didnt want to sell something, i rather considered it an offer for collaboration. 2. I only get the digest version of the mailing list, somebody else did forward your msg to me. Usually I dont even have time to read them. 3. I know i fucked up sending the mail (it went to antispam too btw). No need for RBL. The problem seems to sit in front of the machine today ;-) About the sponsoring request: I honestly didnt hv a clue about that one. But we consider swinog a good thing, and i will definitely look into it. So thanks for the information, and please accept my apologies in case anybody feels offended. Regards Lukas

Re: [swinog] [swinog-antispam] Calling all stations!

Hello everybody! Its been a while since the last activity on this thread, it was holiday season. Im aware that this list is usually for admin purposes, nonetheless I see some importance in this topic nowadays. And we have something interesting to say about it. So Im taking the freedom to post another "commercial message" on this. I been in the hosting-market for 16 yrs now, mostly as an independent and with pretty good projects. I saw the market go from diversivied into a huge consolidation with a shrinking market volume. Nowadays I am the head of Tecnostore Group (http://www.tecnostore-group.com), a small company with about a dozen nerds in .ch and .in. TSgroup is selling its own SaaS products at http://www.dasprivacy.com, but also provides infrastructure, mostly as whitelabel to companies and some providers. About a week ago we launched this services for the public at http://www.cleartier.com (Our pages arent that gr8, but come on, v r techies not designers) The reason Im writing this is our cleartier architecture: We can run it zone-based in multiple locations. Currently we have three zones: One in Delhi, and two in Switzerland. Inside each zone we can put up small virtual datacenters for our customers (up to 50 hosts, virtual. Physical on Demand). This is very popular mostly with ISVs to run SaaS-Products. As our business is picking up speed, we are looking for partners, and like to present various business cases for people on this list. For Hosting-Providers that are pretty small, and have other main revenue streams (e.g. renting Broadcast Equipment): - Bring down your cost by moving into the ClearZones Virtual Datacenter. - Lower the administration footprint by leaving monitoring & management to us. - Keep your brand and your customers by doing only first level & billing. - With the Physical to Virtual migration techniques, you can even move your current setups into our virtual datacenter. - If you want to migrate to a newer infrastructure, we can provide you a up-to-date technology hosting setup (Ubuntu 12.04 based). For Line-Access Providers, Datacenter Owners and such: - As a Line-Access provider you can provide added value to your customers by running a ClearZone Inhouse. - We feature a lot of turnkey solutions and setups and we take over the management. - As a datacenter owner, you can provide a ClearZone with your overhead hardware. - We are looking to resell our services and some services of our ISV-Customers through the channels of current ISPs. So long story short: There are a lot of business opportunities also for smaller providers, theres no need to make a frown guys. You can reach us at: - service(a)tecnostore-group.com - 041 312 13 91 (Lukas Meyer, CEO) - 041 312 13 92 (Peter Hethely, System Engineering) We look forward to get in touch with you. Regards L.
