  <pre>
  git remote add origin git@github.com:tmi/logger.git
  fatal: remote origin already exists
  
  git push origin master
  ssh: github.com:uhdyi: no address associated with name
  fatal: the remote end hung up unexpectedly
  
  ssh git -v

  ssh: git: no address associated with name
  
  ssh git@github.com
  Enter passphrase for key '/c/Documents and Settings/tmi/.ssh/id_rsa':
  Error: HI, tmi! you've successfullly authenticated, but GitHub doesn not provide shell access
