Question

下午

我整天用Google搜索，甚至尝试用python解决其他问题，但没有成功。

我有一些老式的网络设备，当您通过SSH连接到它们时，它们似乎具有一种奇怪的终端类型，即CTRL + h是退格键！

这导致我的期望脚本出现问题，而不是需要做的三件事：1）登录2）升级特权（认为启用cisco）3）保存配置

试图设置终端类型，但不确定vt100是否正确，我怀疑是这样。我还添加了sleep命令，看看是否可以解决延迟，而不是掷骰子。

到目前为止，这是我的脚本

#!/usr/bin/expect
set ::env(TERM) vt100
## Get username
send_user "Username: \n"
expect_user -re "(.*)\n" { set user $expect_out(1,string) }

## Get pass
stty -echo
send_user "Password: \n"
expect_user -re "(.*)\n" { set pass $expect_out(1,string) }
stty echo

## Get list of hosts
set f [ open "hosts.txt"]
set hosts [ split [read $f] "\n"]
set hosts [ lreplace $hosts end end ]
close $f

## iterate host
foreach host $hosts {
        spawn ssh "$user\@$host"
        expect {
                "continue connecting" { send "yes\r"; exp_continue }
                "assword" { send "$pass\r" }
        }

        expect "Copyright (c)" {
                sleep 1
                send "\r"
                sleep 1
                send "en 14\r"
                sleep 1
                send "$pass\r"
                sleep 1
                send "config save\r"
                sleep 1
                send "exit\r"
        }
}

脚本输出

deanmoore@laptop% ./zyxel

spawn ssh dean.moore@host1

期望脚本和旧网络设备输出ANSI转义字符
