• 涉及脚本

#!/usr/bin/expect

set ipaddress "192.168.75.130"
set passwd "root"
set timeout 30

spawn ssh root@$ipaddress

expect {

"yes/no" { send "yes\r",exp_continue }
"password:" { send "$passwd\r" }

}

#加上下面这行代码，作用是：登录上远程主机之后不立即退出！！！

#!/usr/bin/expect

#使用位置参数的形式，让脚本编写更加灵活，适用范围更加广泛！！！
set ipaddress [ lindex $argv 0 ]
set user [ lindex $argv 1]
set passwd [ lindex $argv 2 ]

set timeout 30

spawn ssh $user@$ipaddress

expect {

"yes/no" { send "yes\r",exp_continue }
"password:" { send "$passwd\r" }
