问题 I have created a Kubernetes cluster on my virtual machine and I have been trying to expose this to Internet with my own domain(for eg, www.mydomain.xyz). I have created an ingress resource as below and I've also modified kubelet configuration to have my domain name. All my pods and services are created in this domain name (Eg, default.svc.mydomain.xyz) root@master-1:~# kubectl get ingress NAME CLASS HOSTS ADDRESS PORTS AGE test-ingress <none> www.mydomain.xyz 192.168.5.11 80 5d20h root@master

问题 I am trying to look up domain asynchronously in c++. The reason is I want to be able to effectively add a time out period in case the system can't look up the domain. I came across the getaddrinfo_a() command so I decided to give it a try. However cancelling any dns look up that will not succeed (such as when there is no internet connection) will never take less than 20 seconds on my machine. Here is a simple example of this: #include <iostream> #include <netdb.h> #include <string.h> #include

问题 I have an IIS server With a default Website running, an react app running in the the /LandingPage path and an API used by the React app in the /api, so basically I have: localhost:80/ -> Default MVC website localhost:80/LandingPage -> React APP localhost:80/api -> API to be consumed by the APP. Currently I have a domain pointing to the server, so I can access it externally, but I want to create a sub-domain to the APP/API so I don't need to see the /LandingPage in my URL's. Am I able to set

问题 I currently have an Heroku app that is being served over a CDN. I have just added Fastly to my Heroku app as an addon and I am struggling to configure it properly. Here is my current configuration: I have my domain registered on GoDaddy with the following CNAME configuration: Host: www Points to: my-site-herokuapp-com.global.ssl.fastly.net TTL: Custom Seconds: 600 Here is the GoDaddy forwarding configuration (not sure if this matters): Forward to https://www.my-site.io/ (301 & forward only)

问题 I'am trying to find out, why it fails to send mails from my server with GMail. For this I use SwiftMailer but I can enclose the problem to the following isolated code: <?php $sock = stream_socket_client('tcp://smtp.gmail.com:587', $errno, $errstr); if (false == $sock) { die('error'); } $server_response = fread($sock, 4096); echo $server_response . PHP_EOL; fclose($sock); When I run this code on my local machine (Windows 10, XAMPP, PHP 5.6.24), the output is: 220 smtp.gmail.com ESMTP

问题 I'm having a hard time finding information about whether or not .Net (C# specifically if it matters) respects the TTL values for DNS entries. I believe it does not based on the information I found here. I noticed in other places that Java also does not respect DNS TTL values (Any way to make Java honor the DNS Caching Timeout (TTL)?). Am I right that the only way to control how long a DNS lookup is cached is by using the ServicePointManager.DnsRefreshTimeout property? If this is a case does

问题 I can check for the availability of a an individual domain via whois abc123.com . I can't figure out how to check the availability of a whole set of domains that match criteria , like XXX YYY . Z . where X is any 3 of the same letters, Y is any 3 of the same numbers, and Z is any of com, org, or io. Like aaa111.org That's just an example case, but you get the idea - I'd like to specify strings, patterns, and endings, and see what's available. I can do this kind of string matching with Regex,
