What is the best, secure way to write to a named pipe in Linux? 在Linux中写入命名管道的最佳安全方法是什么? Or, how can I make a named pipe secure?
或者,如何使命名管道安全?
Here's how I write to the pipe on linux using PHP: 这是我使用PHP在Linux上写入管道的方式:
$con = fopen("/tmp/myFIFO", "w");
fwrite($con, "UP\n");
fclose($con);
I wish to make it more secure. 我希望使其更加安全。
This is how I create the pipe in C: 这就是我在C中创建管道的方法:
int pc;
char mode[] = "0777";
int i = strtol(mode, 0, 8);
pc = mkfifo(FIFO, 0);
if(pc < 0) {
printf("Failed in creating a pipe\n");
printf("Exiting...\n");
exit(1);
}
else {
printf("Success in Creating Pipe\n");
chmod("/tmp/myFIFO", i);
}
You can use umask
to control the permissions of the files you create. 您可以使用
umask
来控制所创建文件的权限。 You also have chmod
in php as well. 您也有php中的
chmod
。
However, you also have posix_mkfifo
available, which exactly fits your purpose: 但是,您也可以使用
posix_mkfifo
,它完全符合您的目的:
bool posix_mkfifo ( string $pathname , int $mode ) bool posix_mkfifo (字符串$ pathname ,int $ mode )
