ssh stuck during connection

Hello everyone, 

 

I've got a problem concerning the connection with the ssh client to dropbear on uClinux. 

 

What i've done so far: 

compiled dropbear to uclinux 

generated local rsa & dsa keys 

tried to connect with "ssh root@<ip_adress>" 

i get everytime the same output [1] 

then the local client gets stuck and on uclinux has the following process (99,9% cpu time?) 

 

PID PORT STAT SIZE SHARED %CPU COMMAND 

49 R 431K 0K 99.9 /usr/bin/dropbear -i 2 > /dev/null 

 

Anyone any idea why the programm gets stuck there forever or how i can debug it further?
