Question

I am currently writing a service that should take cleartext commands and then return something according to thoose commands, which is also in cleartext.

I have this odd problem with BufferedReader, or, it might be telnet that is odd, for some reason the BufferedReader reads the first command, however that command is ignored no matter what i do, which i can get around by sending the first command twice, but that is just stretching it a bit, in my oppinion.

The code below is in a run() method.
Then i set out as a PrintWriter and in as a BufferedReader.
The runs variable is by default true.

out = new PrintWriter(handle.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(handle.getInputStream()));
while (runs) {
    String msg;
    msg = in.readLine();
    String[] command;
    command = msg.split(" ", 3);
    /* do something with the command */
}

So my question is if BufferedReader is ignoring the first line or is it telnet that is not coorperating with me?

If it is something else, then please enlighten me.

EDIT
I got this debug message:

Debug: ���� ����’������/nick halmark

so i suppose that it is about all the questionmarks.

Answer 1

I am actually using the latest Putty since i am developing on a windows box… and as far as i recall… then it does not exist by default

If you are using PuTTY, you need to choose the “Raw” Connection Type.

Microsoft telnet servers like to have some content/protocol negotiation at the beginning, so PuTTY will do this by default as per the RFC 854 spec. That’s the garbage that you are reading.
