Eclipse

Remote System Explorer

This allows you to edit files that are on an external server on eclipse locally to be automatically uploaded

Go to eclipse download page and get Eclipse IDE for C/C++ Developers
Unzip it to a accessible location I usually unzip it to C:/eclipse, tin the eclipse.exe file and select a workspace location
Open Remote System Explorer Perspective. go to Window -> Perspective -> Open Perspective -> Other
Select Remote System Explorer
Create a new connection
1. Select SSH Only
2. Fill Host Name (can be IP of the server)
3. Fill Connection Name Any name to identify the connection
4. Uncheck Verify host name option
5. Everything else leave as it is, you can click on Finish
when asked for you password use the one you use to login into that server

Install Eclipse on Linux from .tar

Get tar from eclipse download page
Change to the directory you download the tar.gz file and untar it into /opt folder
- sudo tar -zxvf eclipse-cpp-mars-1-linux-gtk-x86_64.tar.gz -C /opt/
Create eclipse.desktop file executing the following command:
- sudo vim /usr/share/applications/eclipse.desktop

Put the following contents on the eclipse.desktop file:

 [Desktop Entry]
 Name=Eclipse
 Type=Application
 Exec=/opt/eclipse/eclipse
 Terminal=false
 Icon=/opt/eclipse/icon.xpm
 Comment=Integrated Development Environment
 NoDisplay=false
 Categories=Development;IDE;
 Name[en]=Eclipse

Install desktop file executing the following command

sudo desktop-file-install /usr/share/applications/eclipse.desktop

Create a symlink in /usr/local/bin

sudo ln -s /opt/eclipse/eclipse /usr/local/bin/eclipse

If you are using Ubuntu it should now show up on the Unity Dash search results

Cygwin

Install Cygwin. Recommended Packages:
- bash-completion
- bash-completion-devel
- git
- git-gui
- git-svn
- rsync
- gvim
- vim
- vim-common
- gnome-terminal
- curl
- python and python3
- tar
- apt-cyg
- make
- zip/unzip
- cygutils and cygutils-extra
- wget
- openssh ssh/ssh-agent
- findutils
Install Java JDK as usual and add the following lines to your .bashrc

export JAVA_HOME=/cygdrive/c/Program\ Files/Java/<jdh_version_here>/
export PATH=$PATH:$JAVA_HOME/jre/bin:$JAVA_HOME/bin

Notepad++ Tricks

Install a plugin

Run Notepad++ as administrator (sometimes it gives problems if its not run as admin)
Go to menu Plugins-> Plugin Manager -> Show Plugin Manager

On the Available tab search for the wanted plugin, select it and click on the install button to install it

Useful Notepad++ Plugins

Explorer: plug in to have a file explorer window
Remote file upload NppFTP: plugin to auto-upload files
LocationNav: Plug in for history and track changes.
SourceCookifier
Compare: plug-in to compare files
JSON Viewer: plug-in to format JSON files

Set server keys and Notepad++ to auto-upload files

As an alternative to work with files on a server you can set up Notepad++ to automatically upload files to a server so you can edit them and work on Notepad++ on Windows and they can be automatically uploaded to a server.

Configure NppFTP

Check if NppFTP plugin is installed or install this plugin

Open the NppFTP plugin (Plugins -> NppTFP -> Show NppFTP Window)
In the NppFTP window use the Settings (Gear icon) -> Profile Settings
1. Create a new connection using the "Add New" button/option
- Give the connection a Name: Any text you want to identify this connection
- Select Connection type: SFTP
- Fill the Hostname, Username, Password and Initial remote directory (optional). Example:
In the Authentication tab you can either select one of the two options:
1. Check the "Try keyboard interactive authentication" option if you want to give it your password to connect and every time you start editing a file
- Check the "Try private key authentication" option if you plan to use a key file (see Create and Import private key instructions below), you will NEVER need to give your password
  - Once you have a key file give the path to this generated .ppk file in the "Private key file" field
  - If your key has a passphrase make sure to put it in the "Passphrase" field if not just leave this field blank.

Create and Import private key

In the Linux Server (the one where the files will be automatically uploaded) execute the following commands to create the key
`ssh-keygen -t rsa` cat id_rsa.pub >> ~/.ssh/authorized_keys chmod 600 ~/.ssh/authorized_keys

If you already have a key you can skip the first command

Copy the private key file (id_rsa file generated in the Linux Server) to your Windows machine

I used F-Secure SHH File transfer program to connect to the server and copy the file to my Windows machine. The file is located in your home in the hidden folder ~/.ssh (in F-secure enable the hidden files option in the menu: View-> Show Hidden Files)
In windows use puttygen to convert the private key to the format needed by Notepad++
- Load the downloaded key file (File->Load private key)
- Convert it (Conversion -> Export OpenSSH Key)
- When asked to be saved without passphrase click 'Yes'
- Save it to a location and give a .ppk name (I used npp.ppk)
  
  If you used a passphrase when generating the key with the ssh-keygen -t rsa command, puttygen may ask for it

Virtual Box Install and Config

Install Virtual box.
Create a folder to store everything related to the VM
- put the .iso file there
- create a shared folder
- create folder for the snapshots
- when asked to create a virtual HD create it in that location and create one of at least 64GB

In the VM Configurations modify Processor, RAM, and Video Memory with values appropriate to your host.
Create shared folder and check the auto-mount option
Install VB Guest additions
1. In VB "devices" menu select "Guest Additions" options.
- Click run when prompted. Install kernel modules if a kernel modules error occurs
  - sudo apt-get install linux-headers-$(uname -r)
- Add your user to the vbossf group if you have folder permissions error
  - sudo usermod -aG vboxsf $(whoami)
  - sudo adduser $(whoami) vboxsf
    
    We install this so full-screen mode and shared clipboard/copy-paste can work. Virtual machine needs a restsart so this can take effect.

Switch between gnome and fvwm2

use ION Sessions Manager to open a session on the terminal that is opened and change to the /home directory (use cd ~)

Do a ls -a or ls -lrfa to find the .xinitrc.user file. We need to edit this file.
In the .xinitrc.user file look for Linux case to select either gnome or fvvm2. if you are using vim to edit this file you can use / or ? to search.
Uncomment the option you want, use # to comment out. It should look something like this:
```
case Linux* :
      /usr/bin/X11/gnome
      #/usr/intc/bin/fvwm2
      #twm
  
```
In this example we are selecting gnome and commenting fvwm2
Sometimes you have to remove the session from the ION Sessions Manager manager and create a new session to the same server for the changes to take effect

Enable SSH on WSL

Edit /etc/ssh/sshd_config make sure to set Port (other than port 22), Host Keys, Password Auth... for example it may look like this:

#       $OpenBSD: sshd_config,v 1.101 2017/03/14 07:19:07 djm Exp $
# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.
