#ssh非交互的两条命令
ssh-keygen -t dsa -f ~/.ssh/id_dsa -P ""
sshpass -p "对方账号密码" ssh-copy-id -i ~/.ssh/id_dsa.pub "-o StrictHostKeyChecking=no [email protected]（对方ip）"

yum -y install openssh-clients &> /dev/null
#ping通的网，批量分发密钥
ping -c 1 www.baidu.com &> /dev/null
if [ $? -eq 0 ];then
	ssh-keygen -t dsa -f ~/.ssh/id_dsa -P ""
	for ip in `ping -c 1 ${wd}{1..254}`
	do
  		if [ $? -eq 0 ];then 
			sshpass -p " " ssh-copy-id -i ~/.ssh/id_dsa.pub "-o StrictHostKeyChecking=no root@$ip"
