dns

问题 Have searched everywhere, can't find answer. I have the domain mydomain.com. The root and www records point to my main server, which runs my website. I am now using a separate AWS ec2 instance to set up an email server for my domain. This is running on the subdomain mail . My dns looks like this: A @ webserverip A www webserverip A mail ec2ip To prevent my server from getting flagged for spam, I submitted the amazon reverse dns form here: https://aws.amazon.com/forms/ec2-email-limit-rdns

问题 I've recently bought a domain name, and I'm trying to redirect this domain name to an OpenShift v3 web app. (It is my first time setting up things like this, so bear with my ignorance.) Normally, OpenShift provides a hostname, something like: myapp-myproject.preview.openshiftapps.com Based on conversation with support of my domain name registry company (not GoDaddy), I need to have some static IP from my Web Hosting provider to add to the DNS Entry or NameServer to link to my domain name (in

问题 I have hosted a static website on S3 with suitable bucket policy set. Viewing the "endpoint" in another tab works perfectly fine. After this I created a Hosted zone in route 53 to give it a desirable human readable address. After creating the hosted zone, I have two records in my newly created hosted zone, One being of type NS and the other being of type SOA . So far so good. I go ahead to create a new record set. I add the name as desired, enter type as 'A' - IPv4 Address tick yes for Alias

问题 What's the state of the art in DNS resolver libraries? I am particularly interested in full (not stub) resolvers that support any or all of: making multiple queries in one request packet, complete DNSSEC validation, returning detailed information about DNSSEC validation to the application, and can handle experimental new RRs without much hacking. Async queries are nice but not required. Preferred implementation languages would be C, C++, Python, or Javascript, but I'll look at anything (I'd

问题 I've a small SaaS where each client gets a subdomain (stackexchange.my-saas.com) I've a mailgun account where my main domain is setup and I've created a wildcard SPF record in my DNS and if I add additional domains to my mailgun account with a subdomain, they all verifies correctly. My question is, do I need to add every new clients subdomain as a new domain in mailgun when I have the wildcard SPF record set or can i "legally" just create a from-address for each new client so the header of

问题 I have an image that I would like to use to "containerize" our PHP application connection to an MSSQL database. I start with the Dockerfile: FROM nsidhaye/msphpsql ENV ENVIRONMENT development ENV APACHE_DOCUMENT_ROOT /var/www RUN sed -ri -e 's!/var/www/html!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/sites-available/*.conf RUN sed -ri -e 's!/var/www/!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/apache2.conf /etc/apache2/conf-available/*.conf COPY MyAgsourceAPI /var/www/ COPY MyAgsourceAPI/as_sys2 /var

问题 I am trying to get the DNS Server IP Addresses using python. To do this in Windows command prompt, I would use ipconfig -all As shown below: I want to do the exact same thing using a python script. Is there any way to extract these values? I was successful in extracting the IP address of my device, but DNS Server IP is proving to be more challenging. 回答1: I recently had to get the IP addresses of the DNS servers that a set of cross platform hosts were using (linux, macOS, windows), this is

问题 I'm trying to set up an alias for a domain that is purchased through route 53. The alias is going to point to a page in my site with a URL like this: http://example.com/website/:id My api sets up a hostedZone with the following params: var params = { CallerReference: req.body.projectId, Name: req.body.domain, HostedZoneConfig: { Comment: `the zone created on ${today} for ${req.body.domain}`, PrivateZone: false } }; In the next step, I'm setting up a DNS record with the following params: var

问题 I have database configuration in the properties file: port=8080 host=host-default host-default is obviously DNS. Below is my configuration class: @Configuration @Slf4j public class DatabaseConfig { @Value("${port}") private int port; @Value("${host}") private String hostname; @Bean public DatabaseTemplate databaseTemplate() { try { return new DatabaseTemplate(client()); } catch (Exception e) { log.error("Ex: " + e.getMessage(), e); return null; } } @Bean public Client client() throws

问题 I want to point mysite.com to myapplication.herokuapp.com Searched hard and was speaking with hostgator support, they say - it is impossible, heroku is not supporting A records and CNAME are not able to point from naked domain. 回答1: You can do it with A records…but Heroku really doesn't want you to, and with some good reasons. One thing you can do is run $ host myapplication.herokuapp.com and find out what IP that points to, and then create an A record pointing to that IP. But this is very
