As it is kinda quiet, let me break that stillness with the oh so important question: Who can provide native IPv6? :) That is of course for these two lists: http://www.sixxs.net/faq/connectivity/?faq=native http://www.sixxs.net/faq/connectivity/?faq=ipv6transit Replies offlist are great, flamewars on the list are cool too <grin> Greets, Jeroen

Re: [swinog] RBL's (again) (Was: Anyone from Green here?)

actually about a year and a half ago there was a new spambot which was re-sending the message after a temporary reject. But it did it precisely in 4 minutes after the first rejection, and never tried again. So, increasing the greylisting timeout to 5 minutes has solved the problem :) ----- Original Message ---- > From: Adrian Senn <adrian(a)senn.ch> > To: swinog(a)swinog.ch > Sent: Thursday, September 11, 2008 9:37:08 PM > Subject: Re: [swinog] RBL's (again) (Was: Anyone from Green here?) > > Stanislav Sinyagin schrieb: > > > I don't know anything about proper spammers.

there is at least one reason for not sending email directly: if the server IP address is added to some blacklist like SORBS, the notification is sent to the contact address of the reverse zone. If the server is under the ISP's maintenance, the ISP will (supposedly) notice this event and try its best (haha) to remove the server address from that blacklist. If the end-user's fixed IP address appears in SORBS list, the user will not notice it, and it will take much more time before it's removed. interesting, is there a business case behind? How much would one pay for a reliable and SORBS-free mail relay service? It's actually quite easy to build :) ----- Original Message ---- > From: Per Jessen <per.jessen(a)enidan.ch> > To: swinog(a)lists.swinog.ch > Sent: Thursday, September 11, 2008 12:58:40 PM > Subject: Re: [swinog] Anyone from Green here? > > Stanislav Sinyagin wrote: > > > Anyway, who's going to send email directly from a broadband > > connection, instead of using the ISP's relay? :-) > > > > Provided everything is properly set up, why shouldn't they?

well, I used to support customers which were running mail servers behind a broadband connection. Most spam filters and blacklists like SORBS check the reverse naming, and if it doesn't have words like cable, ppp, dynamic and such, it's quite safe to work with it. It just has to have some decent name, but the name shouldn't be necessarily customizable by the user. Anyway, who's going to send email directly from a broadband connection, instead of using the ISP's relay? :-) ----- Original Message ---- > From: Roman Hochuli <roman.hochuli(a)nexellent.ch> > To: swinog(a)swinog.ch > Sent: Thursday, September 11, 2008 12:20:57 PM > Subject: Re: [swinog] Anyone from Green here? > > Hey Stan > > > There aren't many applications that really depend on the reverse name - > > for most of the things it's enough that the reverse name is a valid one. > > You never tried to operate a mailserver behind a DSL-connection yet, > right? :) > > -- > Best regards, > Roman Hochuli > Operations Manager > > nexellent ag > Saegereistrasse 29 > CH-8152 Glattbrugg > > Phone: +41 44 562 30 40 > Fax: +41 44 562 30 41 > URL: www.nexellent.ch > X-NCC-RegID: ch.nexellent > > Imagination is the one weapon in the war > against reality. > -- Jules de Gaultier > _______________________________________________ > swinog mailing list > swinog(a)lists.swinog.ch > http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

If the reverse mapping points to some valid A record, why do you need to change it? There aren't many applications that really depend on the reverse name - for most of the things it's enough that the reverse name is a valid one. ----- Original Message ---- > From: Per Jessen <per.jessen(a)enidan.ch> > To: swinog(a)lists.swinog.ch > Sent: Thursday, September 11, 2008 11:29:04 AM > Subject: Re: [swinog] Anyone from Green here? > > Marc SCHAEFER wrote: > > > On Thu, Sep 11, 2008 at 10:37:35AM +0200, Per Jessen wrote: > >> One of my customers has just been told he needs to pay to get a DNS > >> reverse map entry for thei Green ADSL line with fixed IP. > >> Is that really true?? > > > > I had a similar query lately, and administration(a)green.ch replied that > > with MPS1 (1 IP address) they won't do it, they will do it only for > > MPS8 and with a delegation. > > That's the answer my customer got too. > > > > > That's a pity, but it's how marketing works. > > It's not only very poor marketing, it's incredibly arrogant.

primary / backup BGP multi homed issue
by Marco Fretz 04 Sep '08

04 Sep '08

Hi SwiNOGers, We've the problem that sunrise is advertising our prefixes from our backup provider instead of the ones from our primary. This is most likely because our backup provider is a downstream customer from sunrise. Our prefixes then get advertised to level3 (and other sunrise upstream peers). Sunrise seems to be level3 downstream customer and prefer our prefixes from sunrise instead of our primary provider, too. The consequence is that most other ISPs are seeing only our prefixes over sunrise and our backup provider. Sunrise changed their as-communities recently so that's no longer possible for our backup provider to influence their local-pref. I think this might be a common problem in primary / backup BGP scenarios. Any ideas how to solve it? Maybe someone from sunrise can contact me off-list? Thanks and best regards Marco
