问题 We are running BIND 9.9.7 on Centos 6.5 and for a long time I have been creating "hostless" DNS entries so that sites work with or without the www. Eg: www IN A 192.168.1.1 domain.com. IN A 192.168.1.1 However, our client wants to use a CNAME record to a cloudfront host and the "hostless" entry doesn't work as a CNAME record. In fact, it more than doesn't work, BIND won't even load the zone file. The error is "failed: CNAME and other data" domain.com. IN CNAME host.cloudfront.net. www IN

问题 AFAIK there is no RFC or other standard to retrieve an avatar (image/icon) from an email address. I think this would be a great feature. One possible solution: Get avatar via DNS user enters his email address. The domain belonging to this email adress DNS gets asked: Avatar for "foo@example.com" DNS replies: Get image from URL. For example: http://example.com/foo.png Questions Is there already a RFC or other standard? Why is there no such standard yet? How to get it come true? I know that

问题 I'm using cPanel version 11.42.0 (build 23). As the title suggests, I'm having problem trying to point my domain to a heroku app by setting a CNAME: www.my-site.com. 14400 IN CNAME something.herokuapp.com I've also removed the A record of my root domain, my-site.com. 14400 IN A x.x.x.x (server IP address) I've waited for more than 4 hours, but the CNAME is still not propagated. When I ran a DNS lookup for www.my-site.com (via http://mxtoolbox.com/SuperTool.aspx), it says that no CNAME record

问题 I am trying to do a simple DNS lookup with Swift code. So far, I have if host != "\0" { let hostRef = CFHostCreateWithName(kCFAllocatorDefault, host.bridgeToObjectiveC()).takeRetainedValue() var resolved = CFHostStartInfoResolution(hostRef, CFHostInfoType.Addresses, nil) let addresses = CFHostGetAddressing(hostRef, &resolved).takeRetainedValue() as NSArray for address: AnyObject in addresses { println(address) // address is of type NSData. } } as per Convert NSData to sockaddr struct in swift

问题 I recently purchased a domain with Yahoo Domains for my GAE app. Where I managed to get the domain mapped into my GAE account. Now, since GAE does not support naked domains, I just placed the CNAME for www to point to Google App Engine. Everything works fine now, i.e. my app can be accessed through http://www.my-example-domain.com The problem is with naked domain (with Yahoo), I am trying to forward the naked domain http://my-example-domain.com to h ttp://www.my-example-domain.com however,

问题 Hi folks I'd appreciate some .htaccess advice. I have two wordpress installations. "A" which is in my ISP's Linux server root directory and "B", which is in a subdirectory of the same server called "directoryB". Actual structure is:= A.com A.com/directoryB/ I own two domain names A.com and B.com. I want people to use the address B.com when accessing everything on directoryB, not A.com/directoryB/. I want to leave the "real" "A" alone - no redirections! I have been assured this can be done

问题 I'm struggling with a mod_rewrite problem. Basically I need to do a secret redirect on the domain name, going from http://domainname.com.someotherstuff.com to http://domainname.com This rule should affect all subdirectories as well. I've understood there are three steps: tell the system if the path matches what we're looking for define the RewriteRule pass the new path to the old one so that the system knows (even if it doesn't show) that the two match I've looked up several posts and

问题 I have an application running on kubernetes and I am using minikube for developing and testing it. I set up the minikube, ingress and application and they are working locally as I described here "Traefik ingress does not work with cluster IP" but I don't know how to connect to my application from a remote machine. What I want to do is, I want to run some performance test and find the bottleneck in my application. The application and minikube are located on machine-A and I want to send some
