Finding DNS server settings programmatically on Mac OS X

由 自作多情 提交于 2019-12-17 20:37:49
问题 I have some cross platform DNS client code that I use for doing end to end SMTP and on windows I can find the current DNS server ip addresses by looking in the registry. On the Mac I can probably use the SystemConfiguration framework as mentioned in the first answer, however the exact method of doing so is not immediately obvious. For instance SCDynamicStoreCopyDHCPInfo returns some of the dynamic DHCP related data but not the DNS server addresses. 回答1: They are also available from /etc

问题 I need some sample code to create/delete zone and A record in microsoft DNS server by C# 回答1: You have to use WMI to invoke the DNSProvider. This to add a record: public void AddARecord(string hostName, string zone, string iPAddress, string dnsServerName) { ManagementScope scope = new ManagementScope(@"\\" + dnsServerName + "\\root\\MicrosoftDNS"); scope.Connect(); ManagementClass cmiClass = new ManagementClass(scope, new ManagementPath("MicrosoftDNS_AType"), null); ManagementBaseObject

PHP Cookies for multiple Domains

由 此生再无相见时 提交于 2019-12-17 18:33:36
问题 I want to create a cookie from one domain once the user is registered in PHP. and make this cookie accessible to 4 other domains not subdomain. I know that cookies are not designed to be accessible for other domains. For example I have set a cookies variable $user_email from domain www.firstdomain.com and want to access it in other domains like www.seconddomain.com, www.thirddomain.com etc. May be this can be done using PHP or JavaScript. Any idea please. Thank you! 回答1: As you have already

直播搭建注意点：负载均衡和分布式部署

由 让人想犯罪 __ 提交于 2019-12-17 18:01:28
作为技术人员，我们常被人问及这样一个问题“直播程序为什么要搭载在分布式部署的服务器上？”其实在直播平台的用户量和数据量小、没有太多流量时，一台服务器完全能够运行的起直播程序，但随着市场的扩张和用户量的增长，应用程序和数据库等所有文件数据都放在一台服务器上就不太保险了。 尤其是直播这种对服务器要求比较高的APP更吃资源，因此我们可能会需要在后期增加服务器，以缓解越来越慢的访问速度和逐渐减少的储存空间。 分布式部署的服务器 分布式部署需要把直播程序拆分开来，搭建到一个又一个的服务器上，服务器之间也会有少许不同，比如业务服务器对CPU的要求高，而数据库服务器则需要更快更稳定的读写速度等。 业务的拆分和分布式部署是服务器单机变多机的重点，应用服务和数据服务分离、使用应用服务器集群改善网站的并发处理能力、数据库读写分离、使用反向代理和 CDN 加速网站响应等等，这些都是需要一步步进行的工作。 实现Web负载均衡 直播程序之所以要分布在多个服务器上，最大的原因就是多服务器可以实现负载均衡，将单个服务器的压力分担到多个服务器和组件上，得以保护Web服务器，使服务器实现高性能的同时降低单点损坏率，提高稳定性。 多种方法实现Web负载均衡 1、HTTP负载均衡 用户发送请求，Web服务器通过修改HTTP响应头中的Location标记来返回一个新的url，完成页面重定向，来达到“负载均衡”

Do Domain Classes usually get JPA or JAXB Annotations or both?

由 馋奶兔 提交于 2019-12-17 17:47:47
问题 I have a Java enterprise application that provides a web service, has a domain layer, and a hibernate persistence layer. In this particular case, there is not a huge difference (at the moment) between the objects I send over the wire, the domain objects, and the persistence objects. Currently the application uses DTO's on the persistence side and annotates the Domain classes with JAXB annotations. However, the more I read and think about it, the more this seems backwards!

Custom Incoming Mail Domain With Google App Engine

由 笑着哭i 提交于 2019-12-17 17:41:53
问题 I have set up a custom domain for my google app engine application, which accepts incoming email. While this works great if you want to use an email address like example@example.appspotmail.com, I would like to use a custom domain like example@example.com. Is it possible to do this? A solution that will not work, is to simply use Google Apps to forward emails to the appspotmail address. This is because I accept emails to any number of email addresses at my domain, and I would need to set up

Rails, Heroku and Subdomains. Is my special case scenario feasible?

由 送分小仙女□ 提交于 2019-12-17 17:34:27
问题 Here is my scenario: I have an application that will have to support multiple clients. Each client will be given a subdomain for there service. We will also have a brochure website that doesn't have the application, its just a website about the product and how potential clients can setup an account with us. Given: www.mycoolsite.com would point to a brochure app on Heroku. client1.mycoolsite.com , client2.mycoolsite.com and client3.mycoolsite.com would all point to the same SaaS application

Domain name for my PC: how to (tried No-IP, DuckDNS and ngrok)

由 梦想的初衷 提交于 2019-12-17 16:54:31
问题 I want: ping server on my PC by it domain name from remote. I have: DynDNS services DuckDns (or No-IP, config in no-ip is even harder). It gets me an IP 94.154.220.216 and (sub)domain http://my_domain.duckdns.org . To configure DuckDNS on PC I need just specify some token and my domain name ( my_domain ). Also I've launched server on lacalhost:3000 . Also when I go to CanYouSeeMee it says that my IP is 94.154.220.216 (that's good). And I configured static IP for my PC (let's say 200.300.1.15

Wordpress wp_remote_post() gives “cURL error 6: Could not resolve host”

由 人走茶凉 提交于 2019-12-17 16:53:36
问题 Since this morning some function in a wordpress site I'm managing is not working anymore. I syslogged the response from it, which gives me: {"errors":{"http_request_failed":["cURL error 6: Could not resolve host: subdomain.example.com"]},"error_data":[]} When I manually run curl from that machine I simply get the html as a response. Since it says it could not resolve the host, I presume the problem occurs before the domain name can be resolved to an ip. So I guess (but not sure) this has
