Thanks for your reply. I have the same error even if I have my server
running. Here is the server code.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <sys/un.h>
#include <unistd.h>

int main(int argc, char* const argv[])
{
        int socket_fd, client_sock_fd;
        int bytes_read, length;
        struct sockaddr_un name;

        const char* const socket_name = argv[1];
        socket_fd = socket(PF_LOCAL, SOCK_STREAM, 0);
        name.sun_family = AF_LOCAL;
        strcpy(name.sun_path, socket_name);
        if (bind(socket_fd, (struct sockaddr*)&name, SUN_LEN(&name)) <
0)
                printf("Error\n");
        listen(socket_fd, 5);

        while(1)
        {
        char *msg;
        struct sockaddr_un client;
        socklen_t client_len;
                client_sock_fd = accept (socket_fd, (struct
sockaddr*)&client, &client_len);
                bytes_read = read(client_sock_fd, &length,
sizeof(length));
                if (bytes_read >0)
                printf("%d", bytes_read);
                msg = (char*) malloc (length);

                read(client_sock_fd,msg, length);
                printf("%s", msg);
        }
        close(socket_fd);
        unlink(socket_name);
        return 0;
}
