yes I'm agree with you, it's a disgusting method and which only work if you 
have one login, ttyS0 and others won't work with this stupid stuff.

both support are enabled in kernel. (Unix98 and BSD), i tried to compile 
again with no bsd support but same problem.


anyway I went back and deleted /dev/tty symbolink link, and made again a 
mknod c 5 0 for tty,
then I launched dropbear instead of telnet, and it's working perfectly with 
dropbear, I got a tty more preciselly /dev/ttyp0, so maybe it's a problem 
with telnet.

I will try to log onto serial port to see if it's work as there is no 
monitor nor keyboard on this machine

thanks anyway !
