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?

Fwd: [MBONED] PIM survey for operators

by Thomas Kernen

FYI. May be of interest to some of the operators in Switzerland. Regards, Thomas -------- Original Message -------- Subject: [MBONED] PIM survey for operators Resent-Date: Fri, 22 Jun 2012 10:39:58 -1000 (HST) Resent-From: Antonio Querubin <tony(a)lavanauts.org> Resent-To: nanog(a)nanog.org Date: Fri, 22 Jun 2012 13:21:41 -0700 From: Stig Venaas <stig(a)venaas.com> To: MBONED WG <mboned(a)ietf.org> The IETF pim working group is conducting a survey in order to advance the PIM Sparse Mode spec on the IETF Standards Track, and would like input from operators. The survey ends July 20th. Please see below for more information. thank you, pim chairs Mike & Stig Introduction: PIM-SM was first published as RFC 2117 in 1997 and then again as RFC 2362 in 1998. The protocol was classified as Experimental in both of these documents. The PIM-SM protocol specification was then rewritten in whole and advanced to Proposed Standard as RFC 4601 in 2006. Considering the multiple independent implementations developed and the successful operational experience gained, the IETF has decided to advance the PIM-SM routing protocol to Draft Standard. This survey intends to provide supporting documentation to advance the Protocol Independent Multicast - Sparse Mode (PIM-SM) routing protocol from IETF Proposed Standard to Draft Standard. (Due to RFC 6410, now the intention is to progress it to Internet Standard. Draft Standard is no longer used.) This survey is issued on behalf of the IETF PIM Working Group. The responses will be collected by a neutral third-party and kept strictly confidential; only the final combined results will be published. Marshall Eubanks has agreed to anonymize the response to this Questionnaire. Marshall has a long experience with Multicast but has no direct financial interest in this matter, nor ties to any of the vendors involved. He is also a member of the IAOC, Chair of the IETF Trust and co-chair of the IETF Layer 3 VPN Working Group. Please send Questionnaire responses to his email address, marshall.eubanks(a)gmail.com. He requests that such responses include the string "RFC 4601 bis Questionnaire" in the subject field. Before answering the questions, please comple the following background information. Name of the Respondent: Affliation/Organization: Contact Email: Provide description of PIM deployment: Do you wish to keep the information provided confidential: Questions: 1 Have you deployed PIM-SM in your network? 2 How long have you had PIM-SM deployed in your network? Do you know if your deployment is based on the most recent RFC4601? 3 Have you deployed PIM-SM for IPv6 in your network? 4 Are you using equipment with different (multi-vendor) PIM-SM implementations for your deployment? 5 Have you encountered any inter-operability or backward- compatibility issues amongst differing implementations? If yes, what are your concerns about these issues? 6 Have you deployed both dense mode and sparse mode in your network? If yes, do you route between these modes using features such as *,*,RP or PMBR? 7 To what extent have you deployed PIM functionality, like BSR, SSM, and Explicit Tracking? 8 Which RP mapping mechanism do you use: Static, AutoRP, or BSR? 9 How many RPs have you deployed in your network? 10 If you use Anycast-RP, is it Anycast-RP using MSDP (RFC 3446) or Anycast-RP using PIM (RFC 4610)? 11 Do you have any other comments on PIM-SM deployment in your network? _______________________________________________ MBONED mailing list MBONED(a)ietf.org https://www.ietf.org/mailman/listinfo/mboned

Gerty vs. Rancid

by Tobias Brunner

Hi list Is anyone of you using Gerty (https://github.com/ssinyagin/gerty) instead of Rancid for doing network gear config backup? If yes, is it worth a try? And for doing mass-config-updates on many switches, is it also usable? Thanks for every input =) Cheers, Tobias -- Nine Internet Solutions AG, Albisriederstr. 243a, CH-8047 Zuerich Support +41 44 637 40 40 | Tel +41 44 637 40 00 | Direct +41 44 637 40 13 Skype nine.ch_support

hosting for 1 powersupply with lan port

by Silvan M. Gebhardt

Hi Swinogers, I'm currently thinking about deploying a Sheevaplug or similar with mosh (http://mosh.mit.edu) as a login jumphost since I am several hours in mobile mode every day and I need a space outside of my network to host a *jump host* please contact me offlist and offer me housing for something like that: http://www.plugcomputer.eu/ All I am taking up is some bandwith (expected bandwith in average probably 1mbit max, half of it for keepalives for outbound vpn tunnels, Power consumption apparently less than 10watts. Need v6 and v4 connection, 1 IP each, public, not firewalled, 1 Plug in the power strip Since this is a rather non-standard thing I'm looking for, but I need it in a datacenter outside my infrastructure, I thought it's best to ask here. Btw, for anyone experienced already or looking into mosh, looking forward for exchange here Good Evening! Silvan

Re: [swinog] "arping" for IPv6 (list cleanup)

by Tobias Brunner

Good Morning Everyone > $ ndisc6 2001:4f8:3:2e::1 eth0 > Soliciting 2001:4f8:3:2e::1 (2001:4f8:3:2e::1) on eth0... > Target link-layer address: 00:11:BC:A5:48:00 > > from 2001:4f8:3:2e::1 > > Do note that if the address does not exist you get what you showed: > > $ ndisc6 2001:4f8:3:2e::2 eth0 > Soliciting 2001:4f8:3:2e::2 (2001:4f8:3:2e::2) on eth0... > Timed out. > Timed out. > Timed out. > No response. My goal is to have an equivalent to "arping -U <my-ipv4-configured-on-eth0> -I eth0" to do a "Unsolicited ARP mode, update your neighbours". When I run "ndisc6 <ipv6-of-a-neighbor> eth0" I get the response. But when I do a "ndisc6 <my-ipv6-configured-on-my-eth0> eth0" I get the "Timed out". Maybe I don't understand it correctly =( > 'ip nei' can be used to look at the current entries, it does not allow > for sending a ND solication, but effectively one can also do: > > in one shell: tcpdump -i eth0 icmp6 > in another: ping6 -i eth0 <address> > > should give you the packets too unless it is cached, but then you can > remove it with 'ip nei flush ...' to force it to be cached again. > > Note that 'ip -4 nei' is effectively showing the ARP tables, while 'ip > -6 nei' is for the ND based information. Thanks! I like the "ip" tool more and more... =) > > gcc -o ndping ndping.c -Wall -lnet -lpcap > > ndping.c: In function ‘callback’: > > ndping.c:65: error: ‘LIBNET_ICMPV6_NS_H’ undeclared (first use in this > > function) > > You need to install the libnet headers for that to work. I've installed "libpcap0.8-dev" and "libnet1-dev" (debian squeeze). Maybe I miss another -dev package, but I can't find which one is missing =( Cheers, Tobias PS: I thought I should cleanup the list and write a new message to not "penetrate" the thread "hosting for 1 powersupply with lan port" anymore =) Sorry for the inconvience and for switching the language in the thread. -- Nine Internet Solutions AG, Albisriederstr. 243a, CH-8047 Zuerich Support +41 44 637 40 40 | Tel +41 44 637 40 00 | Direct +41 44 637 40 13 Skype nine.ch_support
