ip

问题 I read and understand how to block an ip using htaccess: order deny,allow deny from 111.222.33.44 deny from 55.66.77.88 ... allow from all But my list of black IPs includes thousands of IPs. I save all IPs to a blacklist.txt file. Can I use htaccess to call blacklist.txt and block all IPs which are stored in this file? If so, how? 回答1: You can try using variations of RewriteMap. You'll need access to the server/vhost config because that directive only works there. You can then use the map

问题 I need to determine if given IP address is from some special network in order to authenticate automatically. 回答1: Apache Commons Net has org.apache.commons.net.util.SubnetUtils that appears to satisfy your needs. It looks like you do something like this: SubnetInfo subnet = (new SubnetUtils("10.10.10.0", "255.255.255.128")).getInfo(); boolean test = subnet.isInRange("10.10.10.10"); Note, as carson points out, that Apache Commons Net has a bug that prevents it from giving the correct answer in

问题 What's the correct way to get all client's IP Addresses from http.Request ? In PHP there are a lot of variables that I should check. Is it the same on Go? One that I found is: req.RemoteAddr And is the request case sensitive? for example x-forwarded-for is the same as X-Forwarded-For and X-FORWARDED-FOR ? (from req.Header.Get("X-FORWARDED-FOR") ) 回答1: Looking at http.Request you can find the following member variables: // HTTP defines that header names are case-insensitive. // The request

问题 I am using Jekyll and Vagrant on my mac. I found that Jekyll server will bind to 0.0.0.0:4000 instead of 127.0.0.1:4000 . Also gem server will bind to this address by default. I can still visit it via http://localhost:port . But for Jekyll , it seems that the default setting (e.g. 0.0.0.0:4000) requires Internet access. I cannot run Jekyll server without Internet. Is it a small bug? I also use Vagrant . I have set port forwarding(8080 => 4000) in Vagrantfile, since I install Jekyll in Vagrant

问题 I am simply trying to achieve something like this: function getIp() { var urlenter = document.getElementById('io'); var IPOUT = urlenter.IpAdress !------HERE!!!!!!!!------! location.href = IPOUT; } so if I typed 'facebook.com' in 'io' it would set the href to the ip adress of facebook.com 回答1: JavaScript doesn't have any concept of hostnames or IP addresses. You would have to use an external service to resolve an IP address from a hostname. 回答2: That's not possible with JavaScript alone. The

问题 I have a strange problem, I just installed my php web site on a shared hosting, all services were working fine. But after configuring my app I just could visit my web site only once, other attempts gives: "The server is taking too long to respond.". But from other IP i can access, but only once, it seems all ip addressess beeing blocked after first visit(even ftp and other services get down, no access at all from the IP), can anyone help to explore this problem ? I don't think that it's my

问题 I would like to know how to get the IP of a user when they connect to the server n socket.io. I have tried using this code which is supposed to log the connection address and port like this: var io = require('socket.io')(serv, {}); io.sockets.on('connection', function(socket) { var address = socket.handshake.address; console.log('New connection from ' + address.address + ':' + address.port); socket.on('request', function(data) { console.log('Request Sent') length = data.length if (data

问题 How do I get the IP and port of a client with PHP? I tried the script below but it only gives me the IP address. <?php print $_SERVER['REMOTE_ADDR']; ?> 回答1: Port is defined in http server (Apache or other and mostly it is 80 or 443) The PHP $_SERVER variables can be checked at this link. I am sure that 'REMOTE_ADDR' returns the IP address from which the user is viewing the current page. But if your server is behind NAT: If you are serving from behind a proxy server, you will almost certainly

问题 We all know that a TCP socket is identified by a four tuple entry: src ip, dest ip, src port dest port TCP does the job of Multiplexing and Demultiplexing the Data from/to differnt processes running on the host. In case of Demultiplexing, Destination IP information is there only in IP Headers. How come Dest IP is read by Transport Layer (TCP)? Plz explain I m very much confused? 回答1: What is called TCP in this context, is in reallity TCP/IP as in TCP over IP ( UDP/IP is the same thing). In
