Can somebody from Zattoo contact me?
by Rainer Duffner 24 Jan '22

24 Jan '22

Hi, one of our IP-Ranges is attributed by Zattoo to be in Germany, apparently. In fact, the customer has reported that other services have reported the same problem in the last week. I would like to understand why this is the case. Best Regards Rainer

BGP Route Monitoring
by Florin Sfetea 06 Jan '22

06 Jan '22

Salut Mihai, any decent monitoring tool should be able to achieve what you need: PRTG(btw. they just released an alpha linux probe)100 Sensors free https://kb.paessler.com/en/topic/25313-sensor-for-bgp-statusZabbix https://share.zabbix.com/network_devices/cisco/cisco-bgp-ipv4-ipv6-32-bit-a… ,etc. Most have some sort of templates, some with custom options. If you don't want/need the overhead of such an tool you can just build a ba(sh) or python parsing script that does some snmpwalk or ssh 'expect' commands and in the end send email or curl post. ;) Beste Grüsse, Regards si s-auzim de bine Florin Sfetea

BGP Route Monitoring
by Sandoiu Mihai 06 Jan '22

06 Jan '22

Hi I am looking for a route monitoring product that does the following: -checks if a specific bgp route from a specific neighbor is present the BGP table (in some vrf, not necessarily internet routed vrf) of an ASR9K running IOS XR -sends a syslog message or an alarm if the route goes missing The use case is the following: we are receiving same routes over 2 or more bgp peerings, due to best route we cannot really see at the moment if one of the routes ceased to be received over a certain peering. Alternative approach: a product that measures the number of bgp received prefixes from a certain peer. Do you know of such product that is readily available and does not require ssh sessions to the routers and parsing the outputs? I am trying to find a solution that does not require much scripting or customization. Many thanks. Regards Mihai

Problem sending to hotmail / block list S3150
by Marco Kälin 16 Nov '21

16 Nov '21

Hi @ all Actually we have massive problems sending to private microsoft customers (hotmail.com, live.com, etc.) We offer some small smtp mailservices for our customers (smtp smarthost and also a mail encryption and sign service). The standard configuration of our outbound smtp servers is from my point of view set correctly: * Fix IP * Correct SMTP Banner, HELO, RDNS * A Records matches RDNS * SPF Records pass * Tested DKIM signed * Not on any Blacklist (checked with mxtoolbox.com) * No spam activities on this /24 ip range for at least 6 years * Sending to Microsoft Office 365 (Business Customers) works. We registred our IPs on the Microsoft Smart Network Data Service (SNDS). This only reports "All of your IPs have normal status". The MS Support "does not see anything that would preventing your mail from reaching our customers". But it's MS servers that bounce the mail... Remote Server returned '554 5.7.1 <hotmail-com.olc.protection.outlook.com #5.7.1 smtp; 550 5.7.1 Unfortunately, messages from [xx] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [DM6NAM04FT044.eop-NAM04.prod.protection.outlook.com] Has anyone experince with this sort of problem? thanks and great day.

Disable Recursion on Windows Server 2019
by Benoît Panizzon 01 Nov '21

01 Nov '21

Dear Community We have a customer who operates hosting and uses a Windows Server 2019 as DNS for his hosting customers and for which we occasionally receive complaints about this being an open resolver prone to DNS amplification attacks. Customers requirements: * DNS reachable from the Internet, for the domains he is authoritative for. * DNS recursion available for hosting customers in his IP range. He tells me, that he can only switch recursion on and off completely, but not restrict the ip ranges for which is shall be available. My quick search via Google, also only revealed how to turn recursion off completely on a Windows Server 2019. Hopefully some Microsoft Guru on this list, can tell, how to restrict recursive access to certain IP ranges? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

CDN: Access Denied Reference #18.cad1f557.1634833505.1903b12e
by Benoit Panizzon 26 Oct '21

26 Oct '21

Dear Colleagues We have a customer whose IP keep getting blocked by various CDN operators. If we change his IP, this solved the issue for a couple of days, then he is blocked again. Actual IP: 87.102.212.133 At the moment, this IP is being blocked by the CDN used by: klm.com nespresso.com easyjet.com I opened a case with Amazon, as this is the ones that host the easyjet.com CDN but they replied that he is blocked 'upstream' by their customer easyjet. Our customer called the Easyjet Helpdesk, but they have no clue what generates this error and sent him to is ISP :-/ We don't get any kind of complaints regarding the IP of this customer. https://multirbl.valli.org/lookup/87.102.212.133.html Two entries on blacklist I am not familiar with. One of them about an email misconfiguration? All the customer is seing on the webpage is: === snipp === Access Denied You don't have permission to access "http://www.easyjet.com/" on this server. Reference #18.57d61202.1634833697.32bab06 === snapp === Any hints on how to solve or what blocking provider is used (all pages show a very similar message with similar ID) are appreciated. PS: Yes, google is finding reports of this exact issue. None I found provided any useful hint on what causes the issue.

New nameserver node for LI/CH at SwissIX
by Daniel Stirnimann 22 Oct '21

22 Oct '21

Hello Swinog, The TLD zones .ch/.li make use of the RcodeZero Anycast DNS service of nic.at since a few weeks (The nameserver letters d.nic.ch/d.nic.li to be precise). Nic.at has now added an anycast node at SwissIX. In order to get the best possible RTT and increased resiliency against potential DDOS attacks on the DNS infrastructure we encourage network operators peering at SwissIX without using the route servers to get in contact with nic.at for direct peering: AS1921, Peering @ SwissIX https://peeringdb.com/ix/60 IP addresses: 91.206.52.164, 2001:7f8:24::a4 Contact: ops(a)nic.at The RcodeZero Anycast DNS node at this location provides DNS services for multiple other TLDs. Best regards, Daniel -- SWITCH DNS Operations

Anyone from UPC/Cablecom ?
by Florian Blaser 25 Aug '21

25 Aug '21

Hi, Is anyone from UPC/Cablecom on the list? I’ve had a few complaints from our customers that have sporadic trouble reaching our services. All of them being also UPC/Cablecom customers. Suspecting DNS troubles, I’ve asked one of those customers to switch to Google’s Public DNS and this seems to solve the issue. So the issue is probably between our DNS servers and UPC’s. I’ve tried to reach hostmaster(a)cablecom.net as per the SOA record, but this seems to be an unrouteable address. Thanks and sorry for the noise! Take care, Florian

SPF/DMARC sunrise issue
by Marc SCHAEFER 30 Jul '21

30 Jul '21

Hello, I am only using SPF, DKIM and DMARC information to up points in my spamassassin (there are too many badly configured SPF sites around, and they most of the time are not DNSSEC-secured). In general, SPF/DMARC alone is not enough to mark as spam in my opinion. However, someone reported the following issue with Sunrise: apparently they are lacking at least ONE of their webmail SMTP senders in their SPF records: 195.141.178.228 for example. dplanet.ch descriptive text "v=spf1 mx include:spf.sunrise.ch -all" spf.sunrise.ch descriptive text "v=spf1 ip4:195.141.178.100 ip4:195.141.178.101 ip4:195.141.178.220 ip4:195.141.178.221 ip4:195.141.178.223 ip4:195.141.178.229 ip4:195.141.178.94 ip4:195.141.178.95 ip4:195.141.178.96 ip4:195.141.178.71 ip4:195.141.178.199 ip4:195.141.178.74 195.141.178." It especially may break dplanet.ch senders as their DMARC policy is quarantine (sunrise's is none). Gmail was for example reporting random problems depending on the sunrise sender (webmail) SMTP IP address: ARC-Authentication-Results: i=1; mx.google.com; spf=pass (google.com: domain of innocent-buddy(a)dplanet.ch designates 195.141.178.229 as permitted sender) smtp.mailfrom=innocent-buddy(a)dplanet.ch; dmarc=pass (p=QUARANTINE sp=QUARANTINE dis=NONE) header.from=dplanet.ch ARC-Authentication-Results: i=1; mx.google.com; spf=fail (google.com: domain of innocent-buddy(a)dplanet.ch does not designate 195.141.178.228 as permitted sender) smtp.mailfrom=innocent-buddy(a)dplanet.ch; dmarc=fail (p=QUARANTINE sp=QUARANTINE dis=QUARANTINE) header.from=dplanet.ch Sunrise end-user support did not seem to notice yet, so if someone around here has better / direct contact, it would be handy. Have a nice week-end anyway.
