Terminal Controll...

[Brendan zerofor0je]

Hello,

I've written a small reverse-telnet client that connects to a server that
handles all the clients.

the reverse telnet node ( whitch i will refer to as rtn from now on) works
by opening up a pty, and with a simple select() it passes data between the
sockets and the pty that /bin/sh runs on.

Meanwihle, the server program( that i will refer to as trc from now on)
sits and listens for nodes running rtn, once a node connects trc takes
controll over it; my problem?

once a rtn node connects to trc2, it works fine, but im having problems on
the input line ( i've tryed 'nc' in listen mode and it works fine, even
the mangled prompt )

Anyway, my problem is the terminal doesnt work properly for example tpying
on the trc prompt i get this undesired result;

hardk0re$ ls -lah /u lo bi mo ls -lah /usr/local/bin/mozilla
-rwxr-xr-x 1 root root 2.9k Jun 19 17:51
/usr/local/bin/mozilla hardk0re$

As you can see, when i type text it does not 'expand' but after i press
'enter' the desired output that i want on the terminal line is printed
out.

Zhivago from #C freenode aksed me to compile this small program;
---
#include <stdio.h>
#include <stdlib.h>

int main(){
int c;
c = getchar();
printf("%c\n",c);
}
---
As you would expect on a normal terminal ( not my cruddy trc ) it
prints out;
hardk0re$ ./a.out
m <- the letter you typed
m <- the letter printf'd back
hardk0re$

But on trc it behaves oddly,

hardk0re$ ./a.out
../a.out
m
m
m
hardk0re$

If anyone knows how to rememdy this i would be very pleased to hear it,
thank you in advance.

It sounds like you're using cbreak mode instead of raw mode.
Cbreak mode forces input to be delimited with newlines. Raw
mode allows you to handle things one character at a time, but
it also requires you to handle such things as backspaces and
other forms of input line editing.

Thanks, It worked!
