<div><br></div><div>Hello,</div><div><br></div><div>Seems that oned can not access cloud3 machine using ssh. Could you verify that you can ssh to cloud3 from your frontend machine and it does not ask for password? Use the same user as the one that is running oned. It could also be that the ssh hostkey from your frontend is not in the knownhosts file from cloud3, this can be easilly added connecting using ssh from cloud3 to your frontend machine. It will ask you if you want to add the key.</div><div><br></div><div>Tell us if this works for you.</div><div><br></div><div>Bye</div><br><div><html>On Apr 13, 2008, at 7:12 PM, Wang, Lizhe wrote:</html><br class="Apple-interchange-newline"><blockquote type="cite"><div style="margin-top: 0px;
