HPC/Applications/atk/Remote Access using Cygwin

Cygwin preparation

• Install Cygwin/X by running or re-running http://cygwin.com/setup.exe
• Select the following packages for installation (in addition to the default):
  • OpenSSH (in section Net)
  • gVim (in section Editors)
  • nano (in section Editors)
  • X11 (entire section)

Use the Search box in the Select Packages stage to locate the packages by name, for instance:

Configure access to the Carbon license servers

On your windows machine:

• Open a Cywin terminal.
• In the terminal window:

nano ~/.ssh/config

• In the section beginning with Host clogin, add the 3 bold lines below:

Host clogin
       Hostname localhost
       User              username
       Port              33301
       ForwardX11        yes
       ForwardX11Trusted yes
       LocalForward  6200 mgmt03:6200
       LocalForward  6201 mgmt04:6200

• Close the editor (Type Control-X, "Y" to save the file, and Enter to confirm the existing file name.)

• Edit your .bashrc file to set up the license server. In the terminal window:

nano ~/.bashrc

• The file is mostly comments. It's best to simply delete all lines and replace them with the following:

# ~/.bashrc: executed by bash(1) for interactive shells.

# The latest version as installed by the Cygwin Setup program can
# always be found at /etc/defaults/etc/skel/.bashrc

# If not running interactively, don't do anything
[[ "$-" != *i* ]] && return

export QUANTUM_LICENSE_PATH="6200@localhost;6201@localhost"
export ATK_HOME="/cygdrive/c/Program Files (x86)/QuantumWise/atk-12.2.2"

PATH=$ATK_HOME/atkpython/bin:$ATK_HOME/vnl/bin:$PATH

• The last three non-empty lines are the ones relevant for ATK and VNL. The one before is used internally by bash.

• Close all clogin windows that were open.

Run VNL

• Open a connection to mega if you do not have one open. In a Cygwin terminal:

ssh -v -N mega

• Minimize the mega terminal window.
• Open a new Cygwin connection to clogin:

ssh clogin

• Minimize the clogin terminal window.
• Open a third Cygwin terminal, and start vnl in it (do not connect to Carbon):

cd atk
vnl &
