They are both similar: 'GetAddrInfo: identifier not found', and 'FreeAddrInfo: identifier not found'. I'm limited in what I can do (I must modify existing code that hasn't been updated since 2012. I'm a co-op, so my degree in computer science is not yet complete, and I may not know certain things). I'm using MFC in a static library. My platform toolset is Visual Studio 2013 - Windows XP (v120_xp). I am using Microsoft Visual Studio

Can someone help me on how I can catch this error? import pygeoip gi = pygeoip.GeoIP('GeoIP.dat') print gi.country_code_by_name('specificdownload.com') Traceback (most recent call last): File "<module1>", line 14, in <module> File "build\bdist.win-amd64\egg\pygeoip\__init__.py", line 447, in country_code_by_name addr = self._gethostbyname(hostname) File "build\bdist.win-amd64\egg\pygeoip\__init__.py", line 392, in _gethostbyname return socket.gethostbyname(hostname) gaierror: [Errno 11001] getaddrinfo failed Well, let’s ask Python what type of exception that is: #!/usr/bin/env python2.7 import

I'm trying to execute API.AI tutorial for building a weather bot for Google Assistant (the one here: https://dialogflow.com/docs/getting-started/basic-fulfillment-conversation ) I made everything successfully, created the bot within API, created the Fulfillments, installed NodeJS on my pc, connected Google Cloud Platform, etc. Then I created the index.js file by copying it exactly how it's stated on API.ai tutorial with my API key from World Weather Organisation (see below). But when I use the bot, it doesn't work. On the Google Cloud Platform the error is always the same: Error: getaddrinfo

The getaddrinfo() function not only allows for client programs to efficiently find the correct data for creating a socket to a given host, it also allows for servers to bind to the correct socket - in theory. I just learned about that and started to play around with it via Python: from socket import * for i in getaddrinfo(None, 22, AF_UNSPEC, SOCK_STREAM, IPPROTO_IP, AI_PASSIVE): i yields (2, 1, 6, '', ('0.0.0.0', 22)) (10, 1, 6, '', ('::', 22, 0, 0)) what makes me wonder about if there is something wrong. What exactly am I supposed to do with these answers? Should I make a listen() ing socket

I have a list of links that I need to check before processing some data. Checking headers with http.get returns error: events.js:72 throw er; // Unhandled 'error' event ^ Error: getaddrinfo ENOTFOUND at errnoException (dns.js:37:11) I cannot handle this error, and exits the process. I tried res.on("error") and try..catch on http.get but nothing works. Below is the code snippet, and here is live example at runnable.com //This is OK getHeaders('http://google.com/404pag-that-does-not-exit'); //Here is the error. //Uncoughtable error! getHeaders('http://doesnotexistooooo.com'); function getHeaders

I've recently installed mongodb on my CentOS 6 VM running on Vagrant. I added port forwarding to Vagrantfile to forward the mongo port config.vm.forward_port 27017, 127017 I configured mongod to start automatically when the server starts and have confirmed that the service starts as intended. however when i run mongo localhost:127017 from my host machine (not vagrant) i get the following error MongoDB shell version: 1.8.2 connecting to: localhost:127017/test Fri Jan 20 13:58:28 getaddrinfo("127.0.0.1") failed: nodename nor servname provided, or not known Fri Jan 20 13:58:28 Error shell/mongo

I have a C program that uses getaddrinfo() . It works as expected on Linux and Mac OS X. I'm in the middle of porting it to Windows. When I compile it (with MinGW gcc) I get the following warnings: ext/socket/socket.c: In function 'sl_tcp_socket_init': ext/socket/socket.c:98:5: warning implicit declaration of function 'getaddrinfo' [-Wimplicit-function-declaration] ext/socket/socket.c:104:9: warning implicit declaration of function 'freeaddrinfo' [-Wimplicit-function-declaration] Then the entire thing fails to link with undefined references to getaddrinfo() and freeaddrinfo() . Now, according

if a start python in a command prompt terminal and try to open some url, I get the following result, despite the name being resolveable through DNS: C:\Windows\system32>nslookup www.google.de Nicht-autorisierende Antwort: Name: www-cctld.l.google.com Address: 173.194.69.94 Aliases: www.google.de C:\Windows\system32>C:\Python27\python.exe Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import urllib >>> urllib.urlopen("http://www.google.de") Traceback (most recent call last): File "

I'm trying to obtain my local (not the external) IP address using the getaddrinfo() function, but I saw the examples provided here , and they where too complex for my needs. Also saw other posts and most of them really wanted to get the external IP, not the local one. Could anyone provide a link to a simple example (or a simple example) about how to obtain my own local IP address using this function ? Just to be clear when I say local, if a router is 192.168.0.1 , my local IP address could be something like 192.168.0.x ( just an example ). getaddrinfo() isn't for obtaining your local IP
