Question

一些背景：使用一台安装了VMA（vSphere Management Assistant）的计算机尝试telnet一个IP，通过脚本修改VM的某些配置。

1.首先，我必须说我可以telnet手动连接的IP，但是当我尝试通过shell脚本进行telnet时，它会一直失败并收到Connection closed by foreign host。

2.然后我更改为使用Expect，并执行相同的操作，我可以成功连接到IP但脚本在中间运行，会话似乎超时，请参阅以下日志：

vi-admin@localhost:~>
vi-admin@localhost:~> more telnetTest.sh

#!/usr/bin/expect

set timeout 20
set ip 10.222.99.108
set port 7001
set user "admin"
set password ""

spawn telnet $ip $port
expect "'^]'."
send "\r";
expect {
    "login:" {
        send "$user\r"
        expect "Password:"
        send "$password\r"
        expect "FGVM*"
        send "config system interface\r"
    }
    "FGVM*#" { send "config system interface\r"}

}
vi-admin@localhost:~> expect telnetTest.sh
spawn telnet 10.222.99.108 7001
Trying 10.222.99.108...
Connected to 10.222.99.108.
Escape character is '^]'.

使用Expect的Telnet在没有任何通知的情况下结束连接
