3 ssh用到的expect脚本spawn ssh -l $USER $HOST
set timeout 60
while {1} {
expect -re "Are you sure you want to continue connecting (yes/no)?" {
# First connect, no public key in ~/.ssh/known_hosts
send "yes\r"
} -re "assword:" {
# Already has public key in ~/.ssh/known_hosts
send "$PASSWD\r"
} -re " ermission denied, please try again." {
# Password not correct
exit
} -re "Connection refused" {
exit
} timeout {
exit
} "#" {
interact
} "losed" {
exit
}
}

主要思路很简单,将data文件中的ip信息显示出来,根据用户的选择,
生成user,root,passwd等信息,再调用expect脚本来自动登录,
脚本写的比较烂,欢迎大家批评指正, |
