The "Host key verification failed" is an error from ssh [1].
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).
It looks like there is an ssh example on slide 10 of the WIEN2k
presentation at [2].
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].

Dear Professor Blaha,
thanks, I used PATH variable extension instead of linking;
it crashed with the message "Host key verification failed. "
