在堡垒机上 自动登录其它机子的 shell(expect)

直接上代码

#!/usr/bin/expect -f
if {$argc < 1} {
    send_user "Usage:\n  $argv0 IPaddr User Passwd Port Passphrase\n"
    puts stderr "argv error!\n"
    sleep 1
    exit 1
}

set ip         [lindex $argv 0 ]
set user       [lindex $argv 1 ]
set passwd     [lindex $argv 2 ]
set port       [lindex $argv 3 ]14 set timeout 6
if {$port == ""} {
    set port 22
}
if {$user == ""} {
    set user "你的通用帐号"
}
if {$passwd == ""} {
    set passwd "通用帐号匹配的密码"
}
spawn ssh -p $port $user@$ip
expect {
      "yes/no" { send "yes\n";exp_continue }
      "password" { send "$passwd\n" }
}
