esx 5 pubkeys

 To allow SSH access to ESXi/ESX hosts with public/private key authentication:  
 Generate public/private keys. 
 Notes  
 These instructions generate two files in ~/.ssh: id_rsa and id_rsa.pub.  
 In ESXi 5.x, the ssh-keygen command is located at /usr/lib/vmware/openssh/bin.  
 
On the remote host, store the public key content, id_rsa.pub in ~/.ssh/authorized_keys.  
 Notes  
 For ESXi 5.0, the location of authorized_keys is: /etc/ssh/keys-<username>/authorized_keys  
 More than one key can be stored in this file.  
 To allow root access, changePermitRootLogin no to PermitRootLogin yes in the /etc/ssh/sshd_config file.  
 To disable password login, ensure thatChallengeResponseAuthentication and PasswordAuthentication are set to no.  
 Reload the service:  
 For ESXi, run the command:  
 /etc/init.d/SSH restart  
 For ESX, run the command:  
 service sshd reload
