[swinog] Re: switch started blocking whois queries?

2022-10-17 Diskussionsfäden Ralph Krämer
Hi Benoît, the whois-service is a hierarchical service like DNS. It starts at IANA and IANA delegates responsibility for ccTLDs towards the country's NIC. In respect to this, the 'official' entry point for .ch queries is the whois service on whois.nic.ch. Switch itself is only the reseller

Hi Benoit, just my 5 cents ... It's not the customer's responsibility to cover issues of their TSP using an unreliable source of geoIP information. The TSP would be able to whitelist exceptions to cover the gap between their unreliable data source and reality until their geoIP source has

I'd strongly recommend to also have a serial console server around for oob. Best pick in my opinion is the avocent/cyclades series. They come in various variants with different amounts of serial ports. connection is RJ45 (use the normal patch infrastructure (within lengths limits) with a specific

all, from what I saw within the last years, more and more companies us cloud based proxy services (like e.g. McAfee Cloud proxies). Since these proxies are sometimes misused to produce nonsense (do evil things) on the internet through these proxies, site admins block IPs belonging to that

Hi Markus, it looks like Microsoft has configured their DNS zones in a creative way and I would expect them to come up with an RFC that justifies their creative way to "rape" DNS at a later time. For now, the way they have set it up looks unsupported to me and I doubt that they get any mails

Hi Markus, [TL;DR] ;-) a MX record pointing to a CNAME is generally not supported and a bad idea. I am sure this is mentioned somewhere in one of the RFCs - but I currently have no time to look this up. A MX should always point to a A record. kind regards Ralph - Am 19. Feb 2018 um
