Toms Online Notebook Sharing my stuff.

Getting Fedora 21 setup and configured to comfortably work with Java on my new Raspberry Pi2. My last entry desribed the install.

I will describe how I configured things to make it efficient to test and develop Java on my Pi2:

1. Boot to multi-user commandline (and how to start the graphical desktop if needed)


2. Samba shared directories


3. SSH without password from my workstations

multi-user commandline

After a few intial boots into the GUI Fxce deskktop, I set it to boot into a simple commandline (no desktop) by default:

">
• sudo systemctl set-default multi-user.target

This is equivalent to RunLevel 3 Multi-User from sysv init.

 If I want an Xfce X session, I just type:

• startxfce4
  
  
  
  • as opposed to the old startx which does not work
    
  
  
  
  

SAMBA Shared Directories

I then started setting up SMB/samba sharing so I could transfer files easier.  

1. sudo yum install samba


2. Edited the /etc/samba/smb.conf
   
   
   • security = user
   
   
   • interfaces = lo eth0 10.0.0.232/24
   
   
   
   


3. (Optional) turned OFF the firewall
   
   
   • sudo systemctl disable firewalld
     
     
   
   
   
   


4. (Optional)disabled selinux in the /etc/selinux/config file

samba now works

SSH without password

I want to be able to easily access the Pi2 without having to enter my
password everytime. I am enabling this because it is on my inner
network, it enables calling 'javac' and other programs remotely from scripts and directly; the Pi2 also has no high security items on it.

1. Generate a public key on the remote computer/workstation
   
   
   • ssh-keygen
   
   
   • answer all the questions
   
   
   • it creates hte following file:
     
     
     • ~/.ssh/id_rsa.pub
       
     
     
     
     
   
   
   
   


2. Add it to the Pi2 ~/.ssh/authorized_keys file
   
   
   • ssh-copy-id -i ~/.ssh/id_rsa.pub pi2
   
   
   
   

I can now access (and call commands) on my Pi2 directly.
