except自动登录的几段代码分享

复制代码

代码如下:

#!/usr/bin/expect -f

set timeout 30

set host “192.168.1.198”

spawn ssh $host

expect_before “no)?” {

send “yesr” }

sleep 1

expect “password:”

send “123456r”

expect “*#”

send “echo my name is fivetrees > /root/fivetrees.txtr”

复制代码

代码如下:

[root@fivetrees ~]# cat expect

#!/usr/bin/expect

for {set i 10} {$i <= 12} {incr i} {

set timeout 30

set ssh_user [lindex $argv 0]

spawn ssh -i .ssh/$ssh_user abc$i.com

expect_before “no)?” {

send “yesr” }

sleep 1

expect “password*”

send “hellor”

expect “*#”

send “echo hello expect! > /tmp/expect.txtr”

expect “*#”

send “echor”

}

exit

复制代码

代码如下:

#!/usr/bin/expect

if {$argc!=2} {

send_user “usage: ./expect ssh_user passwordn”

    exit

}

foreach i {11 12} {

set timeout 30

set ssh_user [lindex $argv 0]

set password [lindex $argv 1]

spawn ssh -i .ssh/$ssh_user root@xxx.yy.com

expect_before “no)?” {

send “yesr” }

sleep 1

expect “Enter passphrase for key*”

send “passwordr”

expect “*#”

send “echo hello expect! > /tmp/expect.txtr”

expect “*#”

send “echor”

}

exit

代码如下:

#!/usr/bin/expect

set timeout 20

if {$argc < 1} {

  puts “Usage: script IP”

  exit 1

}

# 替换你自己的用户名

set user “username”

#替换你自己的登录密码

set password “yourpassword”

foreach IP  $argv {

spawn  ssh $user@$IP

expect

  “(yes/no)?” {

send “yesr”

    expect “password:?” {

      send “$passwordr”

    }

  } “password:?” {

    send “$passwordr”

}

expect “$?”

# 替换你要执行的命令

send “lastr”

expect “$?”

sleep 10

send “exitr”

expect eof
