lan

问题 One task of my program is to scan local wi-fi network for any devices/computers in same network. I found solution to get all working devices IPs, but did not managed to get names of them. I did not find any clue to solve this problem. Any suggestions? 回答1: In order to perform a reverse DNS lookup, you need to call the CFHostGetNames function, like this: + (NSArray *)hostnamesForIPv4Address:(NSString *)address { struct addrinfo *result = NULL; struct addrinfo hints; memset(&hints, 0, sizeof

问题 I have a web server running out of my home. I have assigned it an address such as 192.168.1.123 on port 80. I understand that this is running on my local network. If I go to another computer on my network and type in the server's ip address, I can see the server. Is there a way to access this server from outside my LAN? 回答1: Yes, you need to set your router to forward connections to port 80 to your internal IP address (192.168.1.123). Look for Port Forwarding on your router admin screen which

问题 I am making a nice multiplayer application but I want my application to search for hosts in you lan. I know that you can obtain your own IP quite easily and then brute force all IPs to see if anything is connected, but this is both quite hard work for your computer and it takes a some time as well even when you multithread it properly. There seems to be no good way to obtain the arp table in java but I hope there is something similar where you can obtain all local IP-addresses fast and

问题 Is there any way to keep track of users accessing my shiny app that is shared internally, through: runApp(list(ui=ui, server=server), host="0.0.0.0", port=1234) Also, I was wondering if one can add semaphores to restrict the access of some IPs. Thank you. 来源： https://stackoverflow.com/questions/50396350/monitoring-a-shiny-app-shared-in-my-internal-network

问题 I've made a simple LAN messenger for talking to people on my network using this batch file: @ echo off :A cls echo MESSENGER set /p n=User: set /p m=Message: set /p z=Time: msg /SERVER:%n% * /TIME:%z% "%m%" Pause Goto A What I want to do is encrypt the message before it's sent with an algorithm and then decrypt the message on the recipient's end before the plaintext is displayed. I've looked online and there doesn't seem to be much information on taking received messages and using them. 回答1:

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago . At our new office we have a bit of a problem with file sharing. Currently we are using DropBox, but we'd prefer to use SVN because of all the extra features. The nice thing about DropBox is, as far as I understood, that it also syncs over the LAN with other computeres, so not using the internet heavily. This is

问题 I'm using C++ and accessing a UNC path across the network. This path is slightly greater than MAX_PATH. So I cannot obtain a file handle. But if I run the program on the computer in question, the path is not greater than MAX_PATH. So I can get a file handle. If I rename the file to have less characters (minus length of computer name) I can access the file. Can this file be accessed across the network even know the computer name in the UNC path puts it over the MAX_PATH limit? 回答1: I recall

问题 I'm developing a CodeIgniter app on Win 7, using WampServer v2.0 - I've edited my local HOSTS file so that I can access it here: ht_tp://testdomain/ instead of ht_tp://localhost/testdomain/ to help make it work the same locally as it does when deployed live, with a line like this: 127.0.0.1 testdomain This set up is working fine when I access the pages in browser on the same PC. Now I'm developing some new pages for mobile use, e.g. iPhone, and I want to be able to view my site directly on

问题 Before you say that it is a dupe, this is not the same as this, this, this or this. My question is how do you do it globally. For instance, consider this. I have EasyPHP running in my computer. At present my ip address (global) is 223.231.178.118 Now, let's say there is someone else (maybe in a different country altogether) who wants to access my ip (223.231.178.118). I do know how to access 192.168.x.x from the same network. I just want to know how you can do this globally, if possible. P.S
