问题 I have an IPv4 address. Ex. 172.19.20.21 I used to do this $fs = @fsockopen($ip,$port,$errno,$errstr,3); if( !$fs ){ $error = 'SSC is down'; return Redirect::to('/')->with('error', $error ) ->withInput(Request::except('password')); } It works perfectly fine. Now, I have an IPv6 Address Ex. 3000::1 if ((strpos($ip, ":") > -1)){ // Code for IPv6 check $fs = @fsockopen($ip,$port,$errno,$errstr,3); if( !$fs ){ $error = 'SSC is down'; return Redirect::to('/')->with('error', $error ) ->withInput

问题 Following code is a socket programming sample for a TCP client. But when I run this, connect() is returned as Address family not supported by protocol. I have heard, this problem will happen if the platform does not support ipv6. But AF_INET I wrote is ipv4. Also my server, that is CentOS6.4, is configured within an inet6 addr . Does anyone know why? #include <stdio.h> #include <string.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> int main(){ struct sockaddr_in

Using -vvv I found that it first tries to connect using an ipv6 (which times out) and after that tries to

问题 I have gone through the RFC 4443 and 8201, perhaps I did not understand as I am new to some terminology described in these RFC but I want to understand the implication of using payload in ICMP packet to big message? As per the RFC 4443 Linkt to 4443 RFC The payload will contain as much of invoking packet not exceeding the minimum path MTU in packet to big message. I don't understand the use case of such payload, even in the RFC 8201 there is no mention about the usages of payload. only one

问题 What I am trying to achieve is binding an IPv6 socket to any address of just one particular device , not system-wide. My intuition is that I could setsockopt() with SO_BINDTODEVICE followed by a bind to :: . It mostly does what I expect it to do. The behaviour is the same in v4. The sockets bound to an interface with SO_BINDTODEVICE will only accept connections made to addresses on that interface. That much is expected. However, I run into errno "Address already in use", if I'm trying to bind

问题 I have tried to send emails from my server using smtp.gmail.com:587 on ipv6 but I get this error: === Connected to smtp.gmail.com. <** 421 4.7.0 Try again later, closing connection. -> QUIT *** Remote host closed connection unexpectedly. On the server I use swaks to test this using the following command: swaks -6 --server smtp.gmail.com:587 --from from@gmail.com --to to@gmail.com -tls -a LOGIN But if I use the swaks on ipv4 I can send email with no problems: swaks -4 --server smtp.gmail.com

问题 Both my device and the host through which i'm trying to access are in the same subnet. Scenario: I have a switch and a server in same subnet. I have to access switch using ipv6 link local address from the browser in my server. Can anyone pls tell me the exact syntax?? 回答1: To give an answer specific to browsers: for most common browsers, you can't. There is a proposed standard format, as Sander Steffann pointed out, for specifying the interface for a URL, which is in RFC 6874. The developers
