Synchronize remote hosts

18 January 2010 By hemanth 0 

  1. A simple script to sync remote hosts, steps to achieve it :
  2.  
  3. 1.Avoid SCP prompting for password [ local host ] =>
  4. ssh-keygen -t dsa -b 2048 -f ~/key.pub
  5.  
  6. 2.SCP the key for the first time to the [ remote host ] =>
  7.  
  8. scp ~/key.pub remoteuser@remotehost:/home/remoteuser/
  9.  
  10. 3. In remote host : 
  11. [ Authorize the Host from which key was received ]
  12.  
  13. if [ ! -d .ssh ]; then 
  14.      mkdir .ssh 
  15.      chmod 700 .ssh 
  16. fi
  17. mv key.pub .ssh/
  18. cd .ssh/
  19. if [ ! -f authorized_keys ]; then 
  20.      touch authorized_keys 
  21.      chmod 600 authorized_keys ; 
  22. fi
