+=== Steps On Local Machine (manual)
+
+If you do not want to run VisIt's metadata server on the login node, you can connect to your simulation manually. \\
+Do not try it, if you are not an expert (or have some spare time left). \\
+
+=== connect with GUI to simulation
+==== 1) tunnel port on compute node of rank 0 to local machine (forward connection)
+{{{
+#!ShellExample
+ssh -f <USER>@juqueen.fz-juelich.de -L 5609:<COMPUTE-NODE>:5609 -N
+}}}
+* <USER>@juqueen.fz-juelich.de is your login to the front node
+* -L <LOCAL-PORT>:<COMPUTE-NODE>:<REMOTE-PORT> defines the start and end of the tunnel
+* -f tells ssh to go into the background
+* -N instructs OpenSSH to not execute a command on the remote system
+example:
+{{{
+#!ShellExample
+ssh -f jhpc1234@juqueen.fz-juelich.de -L 5609:134.94.143.222:5609 -N
+}}}
+
+==== 2) copy/modify sim2 file to client
+{{{
+#!ShellExample
+scp <USER>@juqueen.fz-juelich.de:.visit/simulations/<SIM2 FILE> .
+}}}
+
+example:
+{{{
+#!ShellExample
+host R63-IF-J02
+port 5609
+key 9fd458909abe0f26
+comment My Simulation
+}}}
+
+modify to:
+{{{
+#!ShellExample
+host localhost
+port 5609
+key 9fd458909abe0f26
+comment My Simulation
+}}}
+
+==== 3) open sim2 file on with !VisIt GUI
+
+==== 4) tunnel port on local machine to compute node of rank 0 (backward connection)
