unix-socket

问题 Writing the C source below using Unix local sockets I got an error about the address already in use. After having checked man 7 Unix for further informations I tried to create a sub-folder where executing my program (obviously modifying the sun_path field on the current folder) but the error was ever the same. Is there someone able to help me? Source code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/socket.h> #include <sys/types.h> #include <sys/un.h> #include

问题 I send data to socket on one side every second, but I can read that data on another side in any moment. Here's the writer: from settings import Config filename = Config.NAVIGATION_SOCKET_FILE client = socket.socket(socket.AF_UNIX, socket.SOCK_DGRAM) client.settimeout(None) while True: try: client.connect(filename) break except Exception: continue messages = ["$GPRMC,125504.049,A,5542.2389,N,03741.6063,E,0.06,25.82,200906,,,*17", "$GPRMC,155604.049,A,5542.2389,N,03741.6063,E,0.06,25.82,200906,

问题 Socket.close() does not stop any blocking socket.accept() calls that are already running on that socket. I have several threads in my python program that only run a blocking socket.accept() call on a unix domain socket that has been closed already. I want to kill these threads by making the socket.accept() calls stop or raise an exception. I am trying to do this by loading new code in the program, without stopping the program. Therefore, changing the code that spawned these threads or that

问题 This question follows on from the following: Communicating between NodeJS and C using node-ipc and unix sockets In regards to the accepted solution (https://stackoverflow.com/a/39848936/1834057), I was wondering if someone might be able to clarify exactly how to send data from C to Node.js . The solution demonstrates sending data from Node.js to C , but not in reverse. I have an application that requires two-way communications, so the missing component is critical for me. My understanding of

问题 Is it possible to use WebSocket over AF_UNIX sockets (Unix-domain sockets)? Is it technically possible, and if so, do any implementations (mainly browser runtimes) support it? 回答1: Yes, this is possible. AutobahnPython supports running WebSocket over any stream-based transport supported by Twisted like: TCP TLS Unix Domain Socket Pipes Serial Please see here. FWIW, it also supports tunneling any stream-based protocol over WebSocket. E.g. it allows you to run SSH over WebSocket (over any

问题 I want to get the same string standard outputted by curl when I type something like: curl --unix-socket file.sock http://path/to/rest/request In my Java code. I figured out I need to use AFUNIXSocket, but I can set just the socket file on connection, so I suppose I have to manage my http connection manually. Is there a way to make it easier? How do I start an http connection through the socket I create? 回答1: So, I tried to manage the http connection by myself, it works but Im still looking

问题 I need to create a script that listens to a unix socket and forward the incoming stream to a bot. The scripts are unable to connect. The issues seems to be related to the order of things. Proof of case I have created a socket and I am able to write to it. In session 1, I create a listener connection nc -lU /tmp/tg.sck In session 2, I write to the socket. while true; do echo "hello"; sleep 2; done | nc -U /tmp/tg.sck The above only works if I do it in that order. ==> Writing before you have a

问题 I have a server written in c++ which creates and binds to an abstract unix socket with a namespace address of "\0hidden" . I also have a client which is written in c++ also and this client can successfully connect to my server. BTW, I do not have the source code of this client. Now I am trying to connect to my server using a client I have written in python with no success. I do not understand why my python client is not working. I am posting the relevant parts of my server and client codes.

问题 Here's the deal, I'm writing a simple tcp socket server in C (with unix system calls) that I'm not able to get to accept connections. From what I can tell, I get through the server initialization just fine, but when I try to connect to the port that I print out (see code below) it refuses as if nothing is there. More to the point, when I netstat that port isn't even in use. I'm not throwing any errors with my current set up, I'm all dried up for ideas. int main(){ int sock_fd; int conn_fd;

问题 I have Android application, which needs to establish unix domain socket connection with our C++ library (using Android NDK) public static String SOCKET_ADDRESS = "your.local.socket.address"; // STRING There is LocalSocket in java which accepts "string" (your.local.socket.address) #define ADDRESS "/tmp/unix.str" /* ABSOLUTE PATH */ struct sockaddr_un saun, fsaun; if ((s = socket(AF_UNIX, SOCK_STREAM, 0)) < 0) { perror("server: socket"); exit(1); } saun.sun_family = AF_UNIX; strcpy(saun.sun
