+These instructions will detail configuring a desktop workstation in the same manner as the support and development teams at Gateworks.  The command examples used within the Gateworks wiki were written and tested using this or a similar configuration.  
+
+Formost Ubuntu Desktop will need to be installed.  
+
+* https://tutorials.ubuntu.com/tutorial/tutorial-install-ubuntu-desktop#0
+
+Alternately live boot Ubuntu off a USB drive or CD. 
+
+* https://tutorials.ubuntu.com/tutorial/try-ubuntu-before-you-install#0
+
+Be sure to allow for your changes to be persistant when using live boot. 
+
+* https://wiki.ubuntu.com/LiveUsbPendrivePersistent
+
+A VM can be used, this method is least preferable.  
+
+* https://askubuntu.com/questions/142549/how-to-install-ubuntu-on-virtualbox
+
+After these procedures are complete run "apt-get update" command.
+
+The following are the package and configuration changes we make at Gateworks for a Linux Development System. These are tailored towards Ubuntu 16.04 x86-64 desktop, though a newer version can be used.
+
+
+== Add Local User
+
+Working as root can be hazardous.  
+
+ * Add local user called 'username'
+{{{#!bash 
+sudo adduser username 
+}}} 
+  - "username" being the user added
+  - follow/complete prompts
+ * Add user 'username' to sudo group group
+{{{#!bash  
+sudo usermod -aG sudo username 
+}}} 
+  - This command will grant your new user sudo privileges 
+  - -aG add to group  
+
+
+== OpenSSH server (allow remote ssh)
+
+* Install
+{{{#!bash 
+sudo apt-get install openssh-server 
+}}}
+ * default configuration should provide operable connections
+* Edit {{{/etc/ssh/sshd_config}}} and set {{{PermitRootLogin yes}}}
+* Start service (or reboot)
+{{{#!bash  
+/etc/init.d/ssh start 
+}}} 
+
+== TFTP Server
+Very popular TFTP server (recommended)
+
+Install the software on a Linux Desktop machine:
+{{{#!bash
+sudo apt-get install tftpd-hpa
+}}}
+
+Modify the config file for the TFTP server software (/etc/default/tftpd-hpa) and set the directory to anything where you would like to host the files (example /var/www/html/tftpboot)
+{{{#!bash
+TFTP_USERNAME="tftp"
+TFTP_DIRECTORY="/tftpboot"
+TFTP_ADDRESS="0.0.0.0:69"
+TFTP_OPTIONS="--secure"
+}}}
+
+Be sure the tftpboot directory has modified permissions and ownership:
+
+{{{#!bash
+sudo mkdir /tftpboot
+sudo chmod -R 777 /tftpboot
+sudo chown -R nobody /tftpboot
+}}}
+
+To re-start after re-configure:
+{{{#!bash
+sudo service tftpd-hpa restart
+}}}
+
+
+== Development Tools
+* install common dev toos:
+{{{#!bash
+sudo apt-get install build-essential git curl wget
+}}}
+
+== Screen
+Screen is an excellent terminal program as well as remote shell/session manager.
+
+{{{#!bash
+sudo apt-get install screen
+}}}
+
+Additionally you may want to customize your ~/.screenrc for scrolling via mousewheel etc:
+{{{#!bash
+cat ~/.screenrc
+defscrollback 5000
+
+logfile /tmp/screenlog
+
+# Escale sequence
+#escape ^uu
+
+# enable scrolling in the terminal (not necessarily in the screen session)
+# if scrollback is scrolling through command history then you need to
+# enter scrollback 'copy mode' via Crtl+a Esc
+termcapinfo xterm* ti@:te@
+
+# status
+hardstatus alwayslastline "%{= kw}%{g}[%=%{ =kw}%{w}%-w%{Y}[%{W}%n-%t%{Y}]%{w}%+w%=%{g}]"
+}}}
+
+If you encounter terminal type issues you can usually fix these by resizing your terminal to 80x24 and setting term type via:
+{{{#!bash
+export TERM=screen
+}}}
+
+Logging:
+* the above .screenrc sets 'logfile' to /tmp/screenlog. Otherwise it defaults to 'screenlog.0' in your current directory
+* start screen with -L to enable logging (to logfile, which is defaulted to /tmp/screenlog if you use the .screenrc above). This will only log the first window
+* to change the logfile name use cntl-A + : + logfile <name>
+* to toggle logging use cntl-A H
+* to dump the current scrollback buffer to a log use cntl-A h which will dump to 'hardcopy.<n>'
+
+
