ssh用到的expect腳本

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
      }
}

主要思路很簡單,將data文件中的ip信息顯示出來,根據(jù)用戶的選擇,
生成user,root,passwd等信息,再調(diào)用expect腳本來自動登錄,

腳本寫的比較爛,歡迎大家批評指正,

運行程序后顯示

-------------------------------------

-plz input your choice(1|2|3|4|5|)
enter q to quit this menu

輸入q退出,
輸入1后顯示

2    192.168.0.81
3    192.168.0.72
4    192.168.0.46
5    192.168.0.7
plz enter your choice

輸入數(shù)字選擇一個ip登錄,輸入q 退出,輸入b回到主菜單,

原帖由 lovegqin 于 2007-11-16 18:48 發(fā)表
ssh root@192.168.0.$1

把它放到一個腳本里。

比如/usr/local/bin 下　起名　lg

當(dāng)要登陸到191
只需 lg 191

但我這里有幾百臺服務(wù)器...
是不同網(wǎng)段的...

ssh 用到的那個腳本為什么我執(zhí)行說
沒有spawn這個命令呢

作者: gucuiwen 時間: 2007-12-12 11:54
ssh 可以用key方式登錄，不需要輸入密碼，又比密碼登錄安全，為什么還要用expect填寫密碼？
