<p>The "Host key verification failed" is an error from ssh [1].</p>
<p><br>
</p>
<p>Thus, it seems like you need to fix your ssh so that WIEN2k can
connect to your remote node (in your case below, it looks like the
remote node is lxbk1177).</p>
<p><br>
</p>
<p>It looks like there is an ssh example on slide 10 of the WIEN2k
presentation at [2].<br>
</p>
<p><br>
</p>
<p>I believe it is common to use ssh-keygen to create a key pair
(private and public key) on the head node and then use ssh-copy-id
to put the public key on each of the remote nodes. However, ssh
can be uniquely configured for a computer system. So, you might
want to search online for different examples on how ssh has been
configured. One example that might be helpful should be at [3].<br>
