问题 I have a nginx instance in AWS that has upstream Application layer. There are two requirements for nginx - keepalive - use resolver to dynamically resolve the upstream I am able to make either of them work. Here is the config for making keepalive work: upstream "backend" { server "appserver.example.com:443"; keepalive 250; } server { resolver 10.0.0.2 valid=60s; server_name _; location / { proxy_http_version 1.1; proxy_pass https://backend; } } Here is the config for DNS resolver to work:

问题 Aim: Get a docker container to use the DNS provided by the host machine, which is a consul agent running in another container, to access services available via traefik reverse proxy.

There is a general node app which returns "Hello World" when you hit the '/' path Container 1. docker run -d --net=host consul agent

问题 What are the size limits on DNS responses? For instance how many 'A' resource records can be present in a single DNS response? The DNS response should still be cache-able. 回答1: The largest guaranteed supported DNS message size is 512 bytes. Of those, 12 are used up by the header (see §4.1.1 of RFC 1035). The Question Section appears next, but is of variable length - specifically it'll be: the domain name (in wire format) two bytes each for QTYPE and QCLASS Hence the longer your domain name is

问题 Sorry if my question may seem messy I have only a basic idea about DNS or hosting. The story is the following: I have created a couple of my personal webpages and registered a domain. Then I found out that I don't need a "big" hosting for my couple of pages and it's better to host a website in the cloud, I chose GCP for hosting, found this tutorial and followed through to successfully achieve my goal of hosting a static website. Then I wanted to share a link to my website in social media and

If I access the site using the address https://example.com everything works normally; but if I

问题 Quick explanation: Home hobby server Some public services, some I'd like to restrict to internal only Since I discovered reverse proxies (😊) I've been migrating everything behind subdomains of my domain, via Apache I then discovered that I could no longer simply use Require local as before, since Apache always sees the public IP address of the client Require forward-dns appears to be the solution I want, however it's not giving the expected result I'm on a dynamic IP, but the results seem

问题 The php system I am supporting posts data to an SMS gateway to send SMS messages. It successfully posts the data over 99% of the time. Very occasionally it will fail with the curl error SSL: no alternative certificate subject name matches target host name 'api.twilio.com' . This can happen in the middle of sending dozens of SMS messages, several will post and get sent, one or two will fail and then the rest will post successfully. I have discussed this error with the SMS gateway provider
