Mailserver migration problems with Apple devices
by Michael Richter 27 Nov '13

27 Nov '13

Hi there does anybody have experience with mailserver migration and apple clients. We have no changed the ip address of our mailserver -> we have changed the A Record from mail.xy.ch to a new IP. Since then we've a lot of calls from clients which are unable to receive mails. On the iPhones, the authentication option has gone!!. When the customer set its back to password it's working again. But I had also some OS X Mail which had the right settings, but didn't work. I had to configure the account from scratch. So it's defnitely an Apple "Problem". Does anybody now why this is not working or why the settings are changed from the device itselfs?

Dear network experts, We would like to kindly ask you to devote a few minutes of your time to filling out our short survey. The survey is focused on network anomalies as a part of our research. We are trying to learn how the term "network anomaly" is understood by experts and network administrators. Your professional opinion will help us to find an accurate description of the term anomaly and to develop better anomaly detection tools. Our findings will then be made available to the network monitoring community. The survey is available via the following link till end of November. https://security.ics.muni.cz/anomaly_survey/ Thank you for your time and best regards, Jan Rejchrt On behalf of CSIRT-MU -- Mgr.

Project of cooperation between Swiss ISPs
by Gregory Agerba 23 Oct '13

23 Oct '13

Dear SwiNOGers, This is a short message targeting small and medium Swiss-based Internet Service Providers. A few days ago I started reaching out a few ISPs, mostly in the region of Zurich/Zug/Bern/Basel, to discuss the possibility of a smart collaboration in a “cooperative” and “constructive” way. I actually wanted to check out if there was any enthusiasm on the idea of building together a network to reach major European Internet Exchange, buy Transit in bulk, peer with larger networks and setup a larger DDoS mitigation service. The idea came when I saw that many smaller ISPs deploy the same type of network, seeking the same advantages and struggle to deploy a wider reach outside Switzerland due mostly to a lack of available manpower or financial backing. Amongst a more human collaboration between tenants, various cross-business opportunities, the idea is to collaborate on: - Establishing a privileged network of trusted companies and people - Enhancing IP Transit Connectivity quality and costs by playing on larger value scales - Enhancing IP Peering Connectivity by reaching various European IXs over the same infrastructure - Enhancing campus-interconnection in Zurich by lowering costs for inter-DC connectivity in Zurich (DWDM/DF) by sharing the same infrastructure - Build and share a larger DDoS mitigation platform These challenges are part of day-to-day hassles that every ISPs companies have to deal. Scepticism of a working business-model has been highlighted by various interested parties. Other topics such as IP Transit rates erosion costs vs. high transport costs and port-fees have been thoroughly considered too. Therefore, for Swiss ISPs who are interested and willing to take a look, we’d like to invite you to join our discussion board – www.swissnog.ch – please keep in mind that this is in no means a board affiliated with SwiNOG and that if you want to debate about it you are most welcome to join rather than reply here. We look forward to seeing you there! -- Gregory

T-Mobile US can not reach us any idea? contact?
by Marco Fretz 18 Oct '13

18 Oct '13

Hi everyone, I know there is possibly no one around here from T-Mobile US. Maybe someone has a contact to T-Mobile US that can possibly have a look into this? I've tried some official e-mail address from whois information months ago but no response. We are AS198288 and our prefix 5.34.248.0/21 has only limited reachability from / to T-Mobile US (mobile / hotspots users and t-mobile website / e-mail). It's no routing issue I guess as traceroutes / ping work. I was in the US a week ago and also had a T-Mobile 4G contract phone. Same issue, ICMP works, TCP / UDP gets blocked to 5.34.248.0/21. I actually think there are some legacy filters in place, maybe they used 5.0.0.0/8 as "private addresses" in the past. Anyone with an idea or a contact to T-Mobile welcome. Thank you very much. best regards Marco

Looking for a fanless server
by Stanislav Sinyagin 17 Oct '13

17 Oct '13

hi, I'm looking for a Swiss supplier that would offer fanless server appliances, as follows: * 19" rack mount, 1RU high * Fanless design (no moving parts), ability to operate in a normal room environment (25C or so) * Modern CPU, like Core i5 or i7, or some latest-generation ARM, or maybe even MIPS architecture of comparable performance * Graphical performance is non-important, a standard VGA is fine, serial or USB console is even better * Two SSD hard drives. Probably a RAID controller, but also fine without it * Support for 2 or more GB RAM * Two or more 10/100/1000 Ethernet ports * Linux support for all hardware components * 1-2 years warranty, replacement within a week by post. This is a one-off, low-volume request, 1 or 2 devices for the start, and maybe 3-5 devices within a year or two. Quotations will be welcome at ssinyagin(a)k-open.com thanks, stan
