推送公鑰：

修改配置：

#!/bin/bash for i in `cat address.txt` do {ssh $ip "sed -ri '/^#UseDns/c\UseDns no' /etc/ssh/sshd_config"}& done wait

修改密碼:

#!/bin/bash read -p "please input password" :pass for ip in `cat address.txt` do {ping -c1 -W1 $ip &>/dev/nullif [ $? -eq 0];thenssh $ip "echo $pass | passwd --stdin root"&>/dev/nullif [ $? -eq 0 ];thenecho "$(date +%F) $ip">>ok.txtelseecho "$(date +%F) $ip">>fail.txtfielseecho "$(date +%F) $ip">>fail.txt fi }& done wait
