    2. KISTI will open the firewall only for the interactive node {{{gaiad}}}. Since PALM jobs are running on the batch nodes, they have to redirect all ssh/scp transfer via {{{gaiad}}}. This is done by internal ssh from the respective batch nodes to the interactive node, which requires to create an ssh-key. Login on gaiad and execute:
-
-{{{   ssh-keygen -t dsa
+{{{
+      ssh-keygen -t dsa
       cat id_dsa.pub >> authorized_keys
 }}}
+      In order to make it work (i.e. to generate the host keys), you have to login once from {{{gaiad}}} to one of the batch nodes, e.g. {{{gaia13}}} and vice versa:
+{{{
+      ssh <replace by user username on gaia>@gaia13   # login from gaiad to gaia13
+      ssh <replace by user username on gaia>@gaiad    # login from gaia13 to gaiad
+      exit
+      exit
+}}}
+      If you omit this step, jobs will abort with a message like "host key identification failed".
