问题 I am developing a part of code using C++ for our project, my code must return a list of all available IPs in a subnet, so I have this scenario: Get my subnet. Test every IP in subnet using a for loop, e.g.: for (int i = 0; i < 254; i++) { testip(X, X, X, i); /* if IP is valid */ vectoriplist.push_back(X, X, X, i); } For find subnet I think I will use IPnetwork utility, but I still have another problem and it's how I can test if the IP is valid on the subnet. I try to use boost.asio , but I

问题 Is there a way to detect the Operating System version of a web server using its IP address (with knowledge that the web server is running php). I haven't attempted to code it yet, as i am a beginner. Is it easy? Is it possible or not possible at all? 回答1: There's no official way to detect OS on a remote server across all operating systems and configurations. It's often considered a security risk to expose such information, since it can be used to research directed attacks based on the version

Is there any documentation available? 回答1: To quote the Azure faq: Microsoft has played a leading role in helping customers to smoothly transition from IPv4 to IPv6 for the past several years. To date, Microsoft has built IPv6 support into many of its products and solutions like Windows 8 and Windows Server 2012 R2. Microsoft

问题 I'm using the socket module in Python to do some basic UDP client-server communication. What I would need to do is quite simple: client sends server a packet, server answers with client's public ip address, port and a number representing the TTL the UDP packet had when it got to the server. This is my main problem: is there any way to recieve a packet with recvfrom() or so, and read the TTL value it had when it reached my server? Thank you very much! Matteo Monti 回答1: I think you want to
