The functions getaddrinfo () and getnameinfo () convert domain names, hostnames, and IP addresses between human-readable text representations and structured binary formats for the operating system 's networking API. Both functions are contained in the POSIX standard application programming interface (API).
getaddrinfo(3) - Linux man page Name. Synopsis. Description. This field specifies the desired address family for the returned addresses. Valid values for this field Return Value. The specified network host does not have any network addresses in the requested address family. The name Files. 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. getaddrinfo_a(3) - Linux man page Name. Synopsis. Link with -lanl. Description. Perform the look-ups synchronously. The call blocks until the look-ups have completed. Perform the look-ups Return Value. The resources necessary to enqueue the look-up requests were not available. Out of The original node, exactly as passed to the getaddrinfo(3) system call. service. The original service, exactly as passed to the getaddrinfo(3) system call. hints. The original hints, exactly as passed to the getaddrinfo(3) system call. res. The original res, exactly as passed to the getaddrinfo(3) system call. See Also. getaddrinfo(3) network The getaddrinfo_a() function performs the same task as getaddrinfo(3), but allows multiple name look-ups to be performed asynchronously, with optional notification on completion of look-up operations. The modeargument has one of the following values: The functions getaddrinfo () and getnameinfo () convert domain names, hostnames, and IP addresses between human-readable text representations and structured binary formats for the operating system 's networking API.

A remote attacker could crash or, potentially, execute code running the library on Linux. How do I patch and protect my server or workstation against the glibc getaddrinfo on Linux operating system? GNU C Library (glibc) could be made to crash or run programs or commands if it received specially crafted network traffic. On a system where the only IPv6 addresses are either loopback or link-local, getaddrinfo("::1") now fails. It used to work. eg: danw@laptop:~> ssh ::1 ssh: Could not resolve hostname ::1: Address family for hostname not supported danw@laptop:~> sudo ifconfig wlan2 add 1234::5678 danw@laptop:~> ssh ::1 The authenticity of host '::1 (::1)' can't be established blah blah blah danw@laptop:~> sudo
If RAI_PASSIVE is specified, the call will resolve address information for use on the passive side of a connection. rdma_getaddrinfo will attempt to resolve the RDMA address, route, and connection data to the given node. The hints parameter, if provided, may be used to
getaddrinfo is a library function in the standard C library, not a command line tool. So trying to execute it is not quite the right path to a solution. You can call getaddrinfo from a python shell if you want: 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."
