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

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

Platform for open audio workshops
by Stanislav Sinyagin 30 May '12

30 May '12

while we're on the get-together topic :) I've built a small platform for audio seminars and workshops: http://trrtrr.net The primary goal was to set up discussions on IP telephony technologies (hence the name), but I'm completely open and if someone has a good topic for discussion, I'll gladly pass the moderator credentials. The conferences are automatically recorded, and then can be easily published somewhere like SoundCloud. cheers, stan

Re: [swinog] Tele2 not reachable?

Hello Thank you for clarification in fact we have around 500 mails waiting to be delivered to @tele2.ch Addresses. Maybe sunrise should either accept those mails and create proper DSNs or make a public statement that tele2.ch addresses are not longer supported...

Pro / Contra Smarthosting
by Benoit Panizzon 24 May '12

24 May '12

Heya Another one on about the same topic. Business Customer with own Mailserver. They ofter want to know, which of our mailservers they can use as smarthost. We usualy tell them, that they operate an own fully connected mailserver which does not need any smarthost to deliver email to the world. Some do not agree. The reasons the tell us are: - It Tech XY has told them that sending via a smarthost is much more reliable. - Their previous ISP asked them to use it's smarthost. - Our Server has better 'reputation' than theirs and thus emails are less likely to be considered spam by some spamfilters. - Some seem to see DNS issues which I never could understand (they have correct PTR and MX settings for their mailservers). The problems I see with smarthosting are: - If an email to a recipient does not make it there, we get the blame even on trivias like 'user unknown'. - We have to punch holes in the anti-spam thorttling measures to allow them to send more emails / time than the usual private customer does. - They can generate huge load peaks if they operate newsletters and similar. - They often do relay bounce emails for strange reasons, or cause mail loops which we do not want to be routed via our infrastructure. - The risk that our infrastructure get's blacklisted because of trojan activities on a customers infrastructure increases. So how do other ISP handle such requests? Do customer with an own fully connected mailserver have any reason to use their ISP's email infrastructure as smarthost?
