expect登录交换机脚本

Question

写了段登录交换机的脚本，进行用户名和密码的判断，怎么这么写登录不上去啊
正常应该是：
telnet 200.2.0.3
登录后提示'>'，输入'en',提示'Password:'输入密码，如果密码正确则得到提示'#'
用下面代码不能实现正常登录交换机，即时密码修改正确，请问如何修改

spawn telnet "200.2.0.3 23"
expect {
"name:" {
send "a\r"
expect "word:"
}
">" {
send "en\r"
expect "word:"
}
"word" {
send "a\r"
}
}
expect "#"

这个和telnet登录的系统版本有关，可以手动登录确定各阶段的标志符， 下面是SSH登录例子，希望对你有参考价值。
[code="shell"]#!/usr/bin/expect
set timeout 5
set username [lindex $argv 0]
set hostip [lindex $argv 1]
set passwd [lindex $argv 2]
set cmdfile [lindex $argv 3]
spawn ssh $username@$hostip
expect {
"yes/no" {send "yes\n"}
}
expect {
"password:" {send "$passwd\n"}
"Password:" {send "$passwd\n"}
}
set f [open $cmdfile]
while {[gets $f line]>=0} {

expect {
"*#" {send "$line\n"}
"*$ " {send "$line\n"}
"*]" {send "$line\n"}
"*: " {send "$line\n"}
"*> " {send "$line\n"}
"*>" {send "$line\n"}
}
}
close $f
expect "#"
send "quit\n"
expect eof
exit
[/code]
