问题 I am using the networktocode ntc-ansible module in Ansible to control Cisco IOS devices (switches currently). I successfully can use ntc_show_Command to get 'show version' and 'show ip int brief' and put the result into a local file. But when I use the -vvv at the end of the ansible-playbook command, I see structured JSON output in the terminal. How do I get a access the "module_args" and the "response" from the ntc_show_command, ie. if i use "show ip int brief" and i want to know the status

问题 I'm trying to use CFWriteStreamWrite to send data from iPhone to a laptop running macox.

问题 In some forum that I was viewed the JSON response of a POST request using Firebug. Say, a user with the email X@Y.com and password Zabc123 posted something on his own page on this forum. And I wanted to post a comment on his post. But before I posted the comment I opened Firebug's Net panel: After I had posted the comment the response that I saw in Firebug was like this: postid 1432 OTHER THINGS ... email X@Y.com password Zabc123 ip 111.111.111.111 lastlogin 1-1-2016 lastpasschange 2-2-2015

问题 Assuming that the client and server send packets according to the order of sequence as shown in the figure, the client does not know FIN has arrived. It sends “hello again” to the server, the server responds to the client with an RST and the RST has arrived. Then if the client is blocking on a read, why it return 0 due to the FIN instead of -1 because the RST? In the 《Effective TCP/IP programming》, it tells us that the core will return ECONNRESET error. My operating system is Ubuntu 12.10. Is

问题 Its a quite simple question, but i'm searching for hours with no result. My use case: one way - Client asks Server for a job other way - Server says client to stop doing current job So its more server-server because both are listening.

问题 I'm little confused about requests module, especially proxies . From documentation: PROXIES Dictionary mapping protocol to the URL of the proxy (e.g. {‘http’: ‘foo.bar:3128’}) to be used on each Request. May there be more proxies of one type in the dictionary? I mean is it possible to put there list of proxies and requests module will try them and use only those which are working? Or there can be only one proxy address for example for http ? 回答1: Using the proxies parameter is limited by the

问题 During the application lifecycle, how can device be put into Access Point mode? Like turning on the Personal Hotspot. And is it possible to assign SSID to that network during runtime? 回答1: There's no way to do the above with public API. If you want to use private api there is a file located in the Preferences folder, along with the com.apple.SpringBoard.plist : /var/mobile/Library/Preferences/com.apple.MobileInternetSharing.plist In that file, you will want to set 1023 for key State to enable

问题 I am trying to implement the code given in this page http://msdn.microsoft.com/en-us/library/windows/desktop/aa366062%28v=vs.85%29.aspx I am using mingw (gcc) to compile this.
