这篇文章主要为大家展示了"如何实现except自动登录"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"如何实现except自动登录"这篇文章吧。

代码如下:

#!/usr/bin/expect -f
set timeout 30
set host "192.168.1.198"
spawn ssh $host
expect_before "no)?" {
send "yes\r" }
sleep 1
expect "password:"
send "123456\r"
expect "*#"
send "echo my name is fivetrees > /root/fivetrees.txt\r"
interact

##----------------------------

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 "yes\r" }
sleep 1
expect "password*"
send "hello\r"
expect "*#"
send "echo hello expect! > /tmp/expect.txt\r"
expect "*#"
send "echo\r"
}
exit

##-------------------------

代码如下:

#!/usr/bin/expect
if {$argc!=2} {
send_user "usage: ./expect ssh_user password\n"
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 "yes\r" }
sleep 1
expect "Enter passphrase for key*"
send "password\r"
expect "*#"
send "echo hello expect! > /tmp/expect.txt\r"
expect "*#"
send "echo\r"
}
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 "yes\r"
expect "password:?" {
send "$password\r"
}
} "password:?" {
send "$password\r"
}
expect "\$?"
# 替换你要执行的命令
send "last\r"
expect "\$?"
sleep 10
send "exit\r"
expect eof
}
使用方法
script_name ip1 ip2 ip3 ...

##---------------------

代码如下:

#!/bin/sh
# -*- tcl -*- \
exec tclsh $0 "$@"
package require Expect
set username [lindex $argv 0]
set password [lindex $argv 1]
set argv [lrange $argv 2 end]
set prompt "(%|#|\\$) $"
foreach ip $argv {
spawn ssh -t $username@$ip sh
lappend ids $spawn_id
}
expect_before -i ids eof {
set index [lsearch $ids $expect_out(spawn_id)]
set ids [lreplace $ids $index $index]
if [llength $ids] exp_continue
}
expect -i ids "(yes/no)\\?" {
send -i $expect_out(spawn_id) yes\r
exp_continue
} -i ids "Enter passphrase for key" {
send -i $expect_out(spawn_id) \r
exp_continue
} -i ids "assword:" {
send -i $expect_out(spawn_id) $password\r
exp_continue
} -i ids -re $prompt {
set spawn_id $expect_out(spawn_id)
send "echo hello; exit\r"
exp_continue
} timeout {
exit 1
}
