ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa &> /dev/null
sed -i '/StrictHostKeyChecking/c StrictHostKeyChecking no' /etc/ssh/ssh_config
rpm -q sshpass &> /dev/null || yum -y install sshpass &> /dev/null
for i in {1..254} ; do
{
  sshpass -p $PASSWORD ssh-copy-id -i ${USER[0]}@${NET}.${i} &> /dev/null
}&
