Best type for IP-address in Hibernate Entity?

由 ╄→гoц情女王★ 提交于 2019-12-06 06:54:41
问题 What is the best type for storing IP-addresses in a database using Hibernate? I though Byte[] or String, but is there a better way, or what do you use? @Column(name = "range_from", nullable = false) public Byte[] getRangeFrom() { return rangeFrom; } public void setRangeFrom(Byte[] rangeFrom) { this.rangeFrom = rangeFrom; } 回答1: I store it in a long , very fast for lookup. You can use the following functions for conversion. public static string GetStandardIP(long numericIP) { string w =

Amazon s3 Pre-signed URL restricted by IP address

由 六月ゝ 毕业季﹏ 提交于 2019-12-06 06:38:11
问题 The client app requests a presigned URL for S3. Currently we limit the time the URL is valid but would like to also restrict it to the client's IP address. Is it possible to create a S3 presigned URL that is restricted to a specific IP address? From what I can tell only CloudFront will let me do this. 回答1: Yes! First, it is worth explaining the concept of a Pre-Signed URL. Objects in Amazon S3 are private by default . Therefore, if somebody tries to access it without providing credentials,

I have a MySQL server running on my Windows 7 computer as a Windows Service. When I try to connect to it using external.ip = my ip address from http://www.whatismyip.com/ in command prompt: mysql -h external.ip -u root -p it returns: ERROR 2003 (HY000): Can't connect to MySQL server on external.ip (10060) I can, however, connect it to it when I change external.ip to the ip address listed with the ipconfig command: mysql -h ipconfig.ip -u root -p I already changed the permissions for root to accept any host (using commands like those from Accessing a mysql database from external host/ip?

Checking if IP address lies within a given range

由 送分小仙女□ 提交于 2019-12-06 05:48:42
I want to check if IP 180.179.77.11 lies between a particular range, say 180.179.0.0 - 180.179.255.255 . I wrote a function which will compare every IP octet with the others. def match(mask, IP): min_ip = mask.split(' - ')[0].split('.') max_ip = mask.split(' - ')[1].split('.') ip = IP.split('.') for i in range(4): print ip[i] + " < " + min_ip[i] + " or " + ip[i] + " > " + max_ip[i] print ip[i] < min_ip[i] or ip[i] > max_ip[i] if ip[i] < min_ip[i] or ip[i] > max_ip[i]: return False return True match("180.179.0.0 - 180.179.255.255", "180.179.77.11") OUTPUT: 180 < 180 or 180 > 180 False 179 < 179

It mimics the "arp -a" command. IPInfo Class: using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Net; /// <summary> /// This class

Binding a new SoapClient to a specific IP address before sending outgoing request

由 人走茶凉 提交于 2019-12-06 05:01:46
问题 Let's say a machine where the application sits on has SoapClient (to be specific, I'm using Microsoft.Web.Service3.Messaging.SoapClient). It communicates toward a remote location with no problem by sending outgoing requests and getting SoapEnvelope in return (well-established process). The above scenario is through the IP assigned to the machine where the application is sitting on. Now, I need to modify this process - we need to add 2 more IPs to the machine, and I need to "bind" outgoing

Express.js: How can I get the ip Address and render a view?

问题 I really think this should be easy. But when I render a jade template, I also want to grab the ip address. My code look like this. app.js app.get('/', index.home) index.js exports.home = function(req, res) { res.render('index'); }; Where can I add something like: var ip = req.header('x-forwarded-for') || req.connection.remoteAddress; //or console.log(req.connection.remoteAddress); 回答1: Just use req.ip and make sure you have app.enable('trust proxy'); if your app is deployed behind a reverse

Testing if an IP address is within a range of addresses with .NET

由 懵懂的女人 提交于 2019-12-06 04:26:56
问题 Does .NET have the notion of IP Address Ranges? I need to test if a given IP address is within a range of addresses. I could write some API that would give me something like IPRange ipRange = IPRange.Parse("127.0.0.1-127.0.0.15"); ipRange.Contains(someAddress); but I don't want to reinvent the wheel if there is already similar functionality built in. 回答1: No, but here is how it can be done (VB since code tag not included in OP) 'test values Dim rangeStart As Net.IPAddress = Net.IPAddress

How to detemine which network interface (ip address) will be used to send a packet to a specific ip address?

由 ﹥＞﹥吖頭↗ 提交于 2019-12-06 04:21:27
I'm writing a SIP stack, and I need to insert an ip address in the message. This address needs to be the one used for sending the message. I know the destination IP and need to determine the NIC (its address) that will be used to send the message.... To expand a bit on Remy Lebeau's comment, GetBestInterfaceEx() is your best bet, if you're on Windows XP or newer. That will work for both IPv4 and IPv6 addresses. GetBestInterface/GetBestInterfaceEx return the index (call it IDX) of the most appropriate interface to use to contact some address. Then you can map that index into a local IP address

Convert signed int to string ip address in SQL Server

问题 I'm retrieving a signed int from a SQL Server database and need to convert it to a "normal" looking dotted string for display to users.
