Porting IPv4 Application to Dualstack IPv4/IPv6

由 不打扰是莪最后的温柔 提交于 2019-12-08 01:59:14
问题 Actually I'm porting an IPv4 server application to a dualstack IPv4/IPv6 application on Linux. The basic function I have solved by using: serv_addr.sin6_family = AF_INET6; serv_addr.sin6_addr = in6addr_any; ... bind(sock, (struct sockaddr *) &serv_addr, sizeof(serv_addr)); ... listen(sock, 5); ... newsock = accept(syn->sock, (struct sockaddr *) &cli_addr, &clilen); I can connect with IPv4 and IPv6 and use the connections. But when I want to get the IP with: switch(data->sa_family) { case AF

Scapy fails to send ipv6 packets

由 末鹿安然 提交于 2019-12-08 00:08:44
问题 Hello everyone i am new here so please be kind. I have been using scapy lately in order to send and recieve ipv6 packets to selected ipv6 enabled servers. The gist of the code is here: text = line[:-1] #destination=getIPv6Addr(line[:-1]) destination="2607:f1c0:1000:60e0:7992:97f7:61b2:2814" source="2001:630:d0:f105:5cfe:e988:421a:a7b7" syn = IPv6(dst=destination,src=source) / TCP(sport=555,dport=80,flags="S")#flag S is syn packet syn.show() syn_ack = sr1(syn,timeout=11) When i execute the

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed last year . My last release of application which is 12.8 is rejected by apple saying that i have to add the IPv6 support to the app, I read and reviewed the recommended apple doc named Supporting IPv6 DNS64/NAT64 Networks thoroughly and came to know that already i am using the

IPv6 Socket Program Problem

由 非 Y 不嫁゛ 提交于 2019-12-07 14:42:15
问题 Seems that flow not going in " for" loop containing accept in ipv6server.c and hence not able to accept and connect with the client. Whats the mistake ? This code is working fine for IPV4 but after IPV6 changes getting this problem ipv6server.c #include <stdio.h> #include <stdlib.h> /* needed for os x */ #include <string.h> /* for memset */ #include <sys/socket.h> #include <netinet/in.h> #include <sys/errno.h> /* defines ERESTART, EINTR */ #include <sys/wait.h> /* defines WNOHANG, for wait()

Is inet_pton() broken for some IPv6 addresses that “look like” IPv4 addresses?

由 自古美人都是妖i 提交于 2019-12-07 13:17:28
I'm using PHP version 5.2.17, and I see that the following works as expected: $x = inet_pton('::F'); $y = inet_ntop($x); print "::F -> $y\n"; Output: ::F -> ::f But the following does not: $a = inet_pton('::FEEF:1886'); $b = inet_ntop($a); print "::FEEF:1886 -> $b\n"; Output: ::FEEF:1886 -> ::254.239.24.134 I would have expected the second code snippet to produce this output: ::FEEF:1886 -> ::feef:1886 What is it about the IPv6 address ::FEEF:1886 that makes PHP think it is really an IPv4 address? The inet_ntop/inet_pton conversion works correctly with other addresses having 0 in the "high" 96

Change WiFi-Direct IP range? Force IPv6 in Android WiFi-Direct?

由 一笑奈何 提交于 2019-12-07 10:21:00
问题 I have two Android KitKat phones, both are running WiFi-Direct groups as Group Owners, let's call them GO1 and GO2 I managed to connect GO1 as a legacy client to GO2 without breaking any of the (previously set) wifi-direct groups. The problem is that, as you might know, the GO IP address is hardcoded in Android source, and is set to 192.168.49.1 Therefore, both of my devices, GO1 and GO2 have the same IP address (**)... each on his local network. My app is both client and server at the same

NAT Traversal and IPv6

由 旧街凉风 提交于 2019-12-07 05:46:43
问题 I am curious about the usefulness of NAT and NAT traversal mechanisms once the deployment and usage of IPv6 increases. We have so many NAT traversal mechanisms (including proprietary) which are intended for mainly IPv4 devices/clients which are behind some kind of residential or enterprise NAT's. Given that NAT came about because of the lack of available addresses in IPv4, is it likely to become redundant once IPv6 is adopted widely in the coming years since IPv6 has enough addresses? Of
