getaddrinfo() is specified in POSIX.1-2001 (and RFC 2553), and Microsoft is known for never following a standard it could extend or pervert, so of course it's a totally different function in Windows. The relevant MSDN page says it "provides protocol-independent translation from an ANSI host name to an address."
It seems to me that GetAddrInfo is sort of a class without a cause, so to speak. Essentially all it really does is handle the mechanics of its own existence--initial creation, copy construction, move construction, assignment, etc. Essentially the only things you can really do with a GetAddrInfo are call its begin and end (or cbegin/cend) to get iterators into an underlying sequence. Dec 23, 2018 · I'm the founder of Curious Viral. I hope this blog will provide you complete information about Linux Technology & I would like to share my technical knowledge with you which I have learned during this period. Dec 21, 2015 · Once getaddrinfo returns, this code first reacquires the Global Interpreter Lock, then drops the getaddrinfo lock (if there is one). So, on Linux, these lines allow concurrent hostname lookups. On Mac, only one thread can wait for getaddrinfo at a time. CVE-2015-7547: glibc getaddrinfo stack-based buffer overflow.

getaddrinfo() function in Python | Pythontic.com Function Name: getaddrinfo . Function Signature: socket.getaddrinfo(host, port, family=0, type=0, proto=0, flags=0) Function Overview: If we know a network service by host name like example.org or the IP address of the network service either in form of IPv4 or IPv6 along with the port number of the network service, getaddrinfo() will return a list of tuples containing information about socket linux - "POSSIBLE BREAK-IN ATTEMPT!" in /var/log/secure Apr 10 06:39:27 echo sshd[22297]: reverse mapping checking getaddrinfo for 222-237-78-139.tongkni.co.kr failed - POSSIBLE BREAK-IN ATTEMPT!

Socket applications often need to convert hostnames like google.com to their corresponding ip address. This is done through dns requests. The socket api in linux provides functions like gethostbyname and getaddrinfo that can be used to perform the dns requests and get the ip address. gethostbyname The first method uses the traditional gethostbyname function to The getaddrinfo() function combines the functionality provided by the gethostbyname(3) and getservbyname(3) functions into a single interface, but unlike the latter functions, getaddrinfo() is reentrant and allows programs to eliminate IPv4-versus-IPv6 dependencies. The addrinfo structure used by getaddrinfo() contains the following fields: As you probably already know, this Tuesday a potentially catastrophic flaw has been identified on glibc function called getaddrinfo(), which performs domain name lookups, contains a buffer overflo Linux socket 網路程式設計 現在已經不用了。[如果你想要設計能通用於 IPv4 與 IPv6 的程式也不用！]在現代，你有 getaddrinfo()
