  <p>what am i missing here?
  Ideas? thanks in advance</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Ok, made it work!<br>
  first, i've logged with my hudson user (<code>sudo su - -s /bin/bash tomcat6</code>) and then, i've deleted my .ssh folder.<br>
  after this, i just followed <a href="http://linuxproblem.org/art_9.html" rel="nofollow">this</a> link, and made a ssh login without password<br>
  now, hudson can do a fetch without have to especify a password</p>
