Listening for IPv6 multicasts on Linux

由 拈花ヽ惹草 提交于 2019-12-10 10:04:58
问题 I'm trying to get a simple multicasting example to work on Linux (I've tried both RHEL 4 2.6.9 and Ubuntu 8.04 2.6.24). The general idea is that I would like the server to bind to a unicast address and then add itself to the group ff02::1. I would then like it to receive multicasts sent to ff02::1. The code below works on Mac OS X 10.5 (in fact, a server running on OS X gets multicasts sent from Linux clients), but I can't get the Linux server side to work. It doesn't get any multicasts. If I

How to handle IPv6 addresses alongside IPv4 PHP

由 你。 提交于 2019-12-10 09:53:54
问题 I'm an iphone developer - new to web dev, so please be patient! I'm currently using MAMP for local testing. I have a highly secure section on my site. Along with requiring a user/pass - it also checks the user's IP. If the account hasn't been used from that IP before, it will add that IP, along with a unique ID, to a holding table, and fire the user an email asking to confirm access them to their account from that location. If the user logs in, and their IP doesn't match any IPs associated

How to convert IPv4-mapped-IPv6 address to IPv4 (string format)?

由 倾然丶 夕夏残阳落幕 提交于 2019-12-10 09:36:59
问题 I have a struct sockaddr structure containing an IPv4-mapped-IPv6 address like ::ffff:10.0.0.1 . I want to obtain only the IPv4 version of it in a string (in this case, 10.0.0.1 ) in C programming language. How do I go about achieving it? 回答1: As your structure contains an IPV6 address, I'll assume your have a struct sockaddr * pointer (let's name it addrPtr ) pointing to a struct sockaddr_in6 structure. You can get the address bytes easily. const uint8_t *bytes = ((const struct sockaddr_in6

gethostbyname replacement for IPv6 addresses

由 梦想的初衷 提交于 2019-12-10 06:15:18
问题 I have a program that uses gethostbyname (in Windows) in order to convert IP address to hostname. But, it works only for IPv4... What is the correct replacement for IPv6? Thanks. 回答1: Looking up gethostbyname in MSDN tells us that it's deprecated and we should look at getaddrinfo, which has all kinds of options for dealing with other addressing families. Or if you're doing address to name translation, you'll end up at getnameinfo 回答2: Use getaddrinfo , which deprecates the old gethostbyname

IP to Country - IPv6

由 家住魔仙堡 提交于 2019-12-10 03:24:13
问题 I've been using an IPv4 to country convertor successfully. eg: get IP of machine and compare to table to get country. I'm updating this currently and with IPv6 around the corner I wanted to ask if there is a solution for converting IPv6 to country? Note: preference for PHP and MySQL thx 回答1: If you're OK with using a web service then my service http://ipinfo.io recently added IPv6 support: $ curl http://ipinfo.io/2001:4860:4860::8888 { "ip": "2001:4860:4860::8888", "hostname": "No Hostname",

Get IPv6 addresses in linux using ioctl

由 做~自己de王妃 提交于 2019-12-10 02:28:34
问题 I trying to get IPv6 addresses in my linux OS like following: sd = Socket_m(AF_INET6_m, SOCK_DGRAM_m, 0); ifc.ifc_buf = buffer_p; ifc.ifc_len = buffSize; Ioctl_m(sd, SIOCGIFCONF, &ifc); It works succesfully if any IPv4 address are configured for interface, but if interface has only one IPv6 address it is not returned by ioctl. For example, I unable to get IPv6 address of the followith interface because only IPv6 address is configured: br1 Link encap:Ethernet HWaddr 00:10:18:2D:BB:34 inet6

亲测在自己的ubuntu14.04环境配置成功，步骤如下： 0.ctrl+alt+t打开终端 1.修改hosts文件(记得备份原件！！！而且不要备份错了orz）： sudo gedit /etc/hosts 将原hosts文件内容改为： 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback 2.安装相关软件包： sudo apt-get install miredo 3.修改防火墙配置文件： sudo gedit /etc/default/ufw 将IPV6=no改为IPV6=yes 4.重启相关服务进程： sudo invoke-rc.d networking restart 5.修改相关配置文件： sudo gedit /etc/sysctl.d/10-ipv6-privacy.conf 将net.ipv6.conf.default.use_tempaddr = 2改为net.ipv6.conf.default.use_tempaddr = 0 6.刷新配置： sudo sysctl --system 7.重启网络管理: sudo service network-manager restart 8.ping测试： ping6 -c 4 ipv6.baidu.com等ipv6网址 9.愉快地使用ipv6 来源：

Detect If IPv6 is Enabled on Windows Machines

由 99封情书 提交于 2019-12-09 19:39:59
问题 I am writing a powershell script that will act as a build compliance test for our servers. One of the things I need to do is detect if IPv6 networking has been disabled. WMI indicates that this information can be found in the IPAddress Property of Win32_NetworkAdapterConfiguration but can be both IPv6 or IPv4. This does not give me a "yes/no" answer I am hoping to find. Other caveats are that I would prefer not to scrape the details by accessing the registry directly, nor scrape from the
