======== Remote ssh into radar2========

=====Radar2================================================================
Radar1 and Radar2 are connected to the University network through radarpi where it takes the local radar analysis network and masquerades them through the pi, and by an ssh into radarpi, you can ssh into either radar computers. Due to the University network settings you must also ssh to radarpi through littlestorm and be connected to the UND VPN.\\
\\
You ---> Littlestorm ---> radarpi network ---> Radar2\\
\\
Through this you could also connect to the RVP8 or the RCP8 as needed.\\

=====Manual SSH=====
You can manually ssh from one machine to another.\\
Assuming you started at littlestorm.\\
  ssh radarpi@10.227.194.19
  ssh radar2
The config file is setup for operator@radar2 to be radar2\\
The password for radarpi is available from [[https://atmoswiki.azurewebsites.net/doku.php?id=atmos:northpolradar:radarpi|radarpi]]\\
Use the radar2 operator password given to you. 

=====Editing local config to ProxyJump ssh======
To ssh from your machine to radar2 in one command you can set up Hosts by editing your config file in .ssh\\
if you don't have a .ssh directory, create one.
  mkdir -p .ssh
then edit/create a text file named config to create Hosts
  nano config
in .ssh/config you can set up Hosts that allow you to shorten your ssh command. The following code is an example of setting up your device to ssh into littlstorm without manually typing ssh firstname.lastname@littlsestorm.atmos.und.edu\\
  Host littlestorm
    HostName littlestorm.atmos.und.edu
    User firstname.lastname
adding ProxyJumps allows your ssh command to jump through a machine, and allows us to jump from our local machine directly to radar2\\
Paste the following into your .ss/config file to be able to ssh into radar2 by typing ssh radar2\\
  Host radar2
    HostName 192.168.50.2
    User operator
    KexAlgorithms +diffie-hellman-group1-sha1,diffie-hellman-group14-sha1
    HostKeyAlgorithms +ssh-rsa
    PubkeyAcceptedAlgorithms +ssh-rsa
    Ciphers +aes128-cbc,aes256-cbc
    ProxyJump littlestorm,radarpi
  Host radarpi
    HostName 10.227.194.19
    User radarpi
    ProxyJump littlestorm
  Host littlestorm
    HostName littlestorm.atmos.und.edu
    User firstname.lastname
 
=====VNC Server=====
Both radar1 and radar2 have a vnc service installed which can be accesed through ProxyJump ssh and port forewording. if your .ssh/config file is setup then the following command allows you to open the server with a vnc viewer where the VNC name is localhost:5901\\
  ssh -J littlestorm,radarpi -L 5901:localhost:5901 radar2
I use TigerVNC which is an open source VNC viewer available [[https://sourceforge.net/projects/tigervnc/files/stable/1.16.2/vncviewer64-1.16.2.exe/download|here]]
