Re: [Vala] GIO run as root Fail

[Edwin De La Cruz <edwinspire gmail com>]

int main () {
    // A reference to our file
    var file = File.new_for_path ("ftp://ftp.gnu.org/";);

    if (!file.query_exists ()) {
        stderr.printf ("File '%s' doesn't exist.\n", file.get_path ());
        return 1;
    }

    try {
        // Open file for reading and wrap returned FileInputStream into a
        // DataInputStream, so we can read line by line
        var dis = new DataInputStream (file.read ());
        string line;
        // Read lines until end of file (null) is reached
        while ((line = dis.read_line (null)) != null) {
            stdout.printf ("%s\n", line);
        }
    } catch (Error e) {
        error ("%s", e.message);
    }

    return 0;
}


I am trying something simpler just with the example that is in the
Wiki, the only thing that does is to list the files in the FTP.

But I get the same result when I run it as root: "Operation not supported".

 When I run it as a normal user I have no problem.
Something else I should do is use GIO to connect to an FTP in an
application that runs as a service, I'm afraid I'll have the same
problem. Do it with CRON or as a service if I'm going to run as root I
will have the same message.

 Any suggestions?
