由 此生再无相见时 提交于 2019-12-12 10:13:00
问题 i have a question on the kubernetes DNS lookup, if i am using in my services deployment "dns" instead of "env", Can my microservice using another microservices in the cluster get the dns names of all the microservices? I get this piece of code, if I use env then I get the the info of host from env. but if I am using dns what format and how do I get the dns names, is there a DNS object I can query on the client side? if (isset($_GET['cmd']) === true) { $host = 'redis-master'; if (getenv('GET

问题 I'm struggling to enforce an SSL connection for a rails app running on Heroku (EU region). I've added the cert (inc Heroku SSL add-on) to a custom domain successfully (if I explicitly state https://..com it works perfectly) But I want to redirect all http requests to a https connection. For apps in the US regions this require pointing custom domain DNS records to .herokussl.com NOT .herokuapp.com.

渗透测试之进行信息收集方法 攻击的重要阶段之一就是信息收集。为了能够实施攻击，我们需要收集关于目标的基本信息。我们获得的信息越多，攻击成功的概率就越高。 　　1.1 服务枚举 在这个中，我们将会展示一些服务枚举的小技巧。枚举是我们从网络收集信息的过程。 我们将要研究DNS枚举和SNMP枚举技术。DNS枚举是定位某个组织的所有DNS服务器和DNS条目的过程。DNS枚举允许我们收集有关该组织的重要信息，例如用户名、计算机名称、IP地址以及其它。为了完成这些任务我们会使用DNSenum。对于SNMP枚举，我们会使用叫做SnmpEnum的工具，它是一个强大的SNMP枚举工具，允许我们分析网络上的SNMP流量。 操作步骤 让我们以DNS枚举作为开始： 　　1. 我们使用DNSenum进行DNS枚举。为了开始DNS枚举，打开Gnome终端，并且输入以 下命令： cd /usr/bin ./dnsenum --enum adomainnameontheinternet.com 请不要在不属于你的公共网站或者不是你自己的服务器上运行这个工具。这里我们 将 adomainnameontheinternet.com 作为一个例子，你应该替换掉这个目标。要当心！ 　　2. 我们需要获取信息输出，例如主机、名称服务器、邮件服务器，如果幸运的话还可以得 到区域转换： 　　3.

Use PHP to Dynamically Add To .htaccess File?

由 痴心易碎 提交于 2019-12-12 08:11:57
问题 What I am trying to do is automate the process of going live with websites. These websites are all dynamically created using htaccess, so here is an example: RewriteCond %{ENV:REDIRECT_STATUS} ^$ RewriteCond %{HTTP_HOST} ^(www\.)?domain\.com$ [NC] RewriteRule ^(.*)$ /folder%{REQUEST_URI}?%{QUERY_STRING} [QSA,L] What I do is add a domain alias for domain.com , and then point it to my server IP and the htaccess file makes it view what is in the /folder. It works fine but we are planning to have

Having trouble building a Dns Packet in Python

由 自闭症网瘾萝莉.ら 提交于 2019-12-12 08:08:50
问题 I'm trying to build a dns packet to send over a socket. I don't want to use any libraries because I want direct access to the socket variable that sends it. Whenever I send the DNS packet, wireshark says that it's malformed. What exactly am I doing wrong? Some things that are wrong with the Dns packet itself: It says it has 256 questions, no class and no type class DnsPacketBuilder: def __init__(self): pass def build_packet(self, url): packet = struct.pack("H", 12049) # Query Ids (Just 1 for

Nginx doesn't get host from embedded DNS in docker 1.10.1

由 一世执手 提交于 2019-12-12 08:01:28
问题 I have several services running in docker containers, and one nginx server in front of them, all containers within the same docker network. Before docker 1.10 I created a dnsmasq container and within nginx set resolver to it so my services can be discovered from nginx. But after upgrading to docker 1.10.1, the dnsmasq image doesn't work. After some research, I tried to use the new "embedded dns" from address 127.0.0.11 instead (which I think should be the correct way to use within docker

GAE naked to www custom domain mapping does not work

由 随声附和 提交于 2019-12-12 07:47:51
问题 I setup a custom domain on GAE using the tutorial at aral balkan to access http;//app.apspot.com at http://app.com. (I can access the app at www.app.com) The tutorial is pretty old(Sep 2008) and it mentions Add four Hostnames for the naked domain (i.e., yourdomain.com without the www) and have them point to IP addresses 216.239.32.21, 216.239.34.21, 216.239.36.21, and 216.239.38.21. I added the required A names to my domain dns, but accessing app.com leads me to a Google 404 page I have used

How can I list ALL DNS records?

由 [亡魂溺海] 提交于 2019-12-12 07:07:51
问题 Is there any way I can list ALL DNS records for a domain? I know about such things as dig and nslookup but they only go so far. For example, if I've got a subdomain A record as test A somedomain.co.uk then unless I specifically ask for it, eg. dig any test.somedomain.co.uk I can't see it. Is there any way (other than looking at the records by going to the DNS manager) to see exactly what all the DNS records are? 回答1: When you query for ANY you will get a list of all records at that level but

DNS records to point to another domain

由 喜欢而已 提交于 2019-12-12 06:37:12
问题 Usually I would upload a .htaccess to redirect a domain to another domain. But can something be done with the DNS settings when there is no hosting set up, to point one domain to another in a similar fashion to a redirect? www.domainA.com -> www.domainB.com 回答1: Your domain can just have a CNAME type, redirecting to your other domain. 回答2: There are many ways to do this. One is to set up a virtual domainA server on the domainB box. Another is to use a web forward in your domainA DNS record.
