title: ssh and agent forwarding in ubuntu 12.10
body: <p>I have a machine X, I login to X and issue an <code>ssh somewhere</code> command which uses key authentication, and it works fine.</p>
  
  <p>When I ssh to machine X from a 12.10 machine (which does not have my special machine X keys), and try the same command above, it fails with <code>Permission denied (publickey).</code> message. I googled around and it looks like this is related to ssh agent forwarding, but I am not sure.</p>
  
  <p>I have faced the same problem trying to ssh from the latest secureCRT too. I tried disabling agent forwarding in secureCRT with no luck.</p>
  
  <p>How do I solve this? If disabling agent forwarding is the key, how do I do it? Do I need to change anything in the destination machine?</p>
