Linux ожидаемый сценарий, иногда заканчивающийся `Соединение закрыто сторонним хостом`, это ожидаемый сценарий или проблема с устройством?

/ 15 февраля 2020

Я использую CentOS 7.6 

$ cat /etc/system-release
CentOS Linux release 7.6.1810 (Core)

Это самая последняя версия ожидания от репозиториев. 

$ expect -version
expect version 5.45

Согласно вашему предложению, я изменил свой код, чтобы сделать это легче исправить, часть аутентификации не должна быть проблемой, поэтому я удалил ее сейчас, ниже приведен мой ожидаемый код, тестирующий устройство без аутентификации. 

$ cat runCommands.exp
spawn telnet 10.220.64.67
set prompt "#"
expect ">"
send "enable\r"
expect $prompt
send "terminal length 200\r"
expect $prompt
send "terminal more off\r"
expect $prompt
send "show hw-inventory details\r"
expect $prompt
send "exit\r"
expect eof

Вот как я работаю Мой ожидаемый сценарий, он запускается правильно, но в конце он просто останавливается. 

$ expect -f ./runCommands.exp
spawn telnet 10.220.64.67
Trying 10.220.64.67...
Connected to 10.220.64.67.
Escape character is '^]'.

Как вы можете видеть выше, я получаю ошибку Соединение закрыто сторонним хостом , и я могу не удалось получить полный вывод команды show hw-inventory details , не уверен, что размер выходных данных может повлиять на это.

Как единственный ресурс, который я знаю для отладки этого сценария ожидаемого добавляет флаг -d Я запустил точно такой же сценарий с этой опцией на случай, если мы сможем получить представление о том, что здесь происходит.

Как вы думаете, это может быть проблемой с сам сценарий ожидаемого или может быть что-то еще, связанное с устройством te lnet?

Если вы готовы сделать это, мы можем провести сеанс screen, и мы можем работать вместе над этим, на этом Я чувствую отчаяние по поводу этой странной проблемы, не зная, как продолжать двигаться вперед.

Это полный ожидаемый результат:

HENKEL_CAPITAL_2-EQU#exit
Connection closed by foreign host.

В предыдущем выводе я вводил команды вручную и он работал правильно, единственная разница в том, что я не использовал терминал больше от и длина терминала 200 команды. 

$ telnet 10.220.64.67
Enter configuration commands, one per line. End with ^Z
HENKEL_CAPITAL_2-EQU>enable
HENKEL_CAPITAL_2-EQU#show hw-inventory details
**[short output... due to the limit of the stackoverflow text box]**
--More--
            mode is not relevant
HENKEL_CAPITAL_2-EQU#exit
Connection closed by foreign host.

Когда я вижу --Более - string Я просто набираю пробел, чтобы получить больше выходных данных, пока не появится последнее приглашение HENKEL_CAPITAL_2-EQU # , затем я просто наберу exit команда.

Проблема здесь: 

send "show hw-inventory details\r"
expect $prompt
send "exit\r"

Вы set prompt "#", что очень опасно. Выход show hw-inventory details имеет символ # (см. Строку part# 82.86S-8609-R6 rev C), поэтому expect $prompt будет успешным, а затем send "exit\r" и соединение будет закрыто.

Решение : Используйте более точную строку для приглашения, например: 

# '[' needs to be backslash escaped or it'll trigger Tcl's command substitution
set prompt "HENKEL_CAPITAL_2-EQU\[>#]"

Похоже, ваша основная проблема заключается в том, что вы чередуете код (особенно эти sleep 1 s!) На разных уровнях, в результате чего получается скрипт, который на самом деле является чистым гиббери sh. То, что код не дает сбоев, является чистой случайностью.

Переписывает раздел с проблемами, пытаясь угадать, что вам нужно ... 

# Handle login
expect {
    "user name:" {
        send "$user\r"
        exp_continue; # keep waiting
    }
    "password:" {
        send "$password\r"
        exp_continue; # keep waiting
    }
    ">" {
        # Got a logged-in prompt so stop waiting (by not exp_continuing)
    }
}

# Handle what's going on remotely; note that we've a prompt at this point
# and can use simple challenge/response coding from here on
set prompt "# "
send "enable\r"
expect $prompt
send "terminal length 200\r"
expect $prompt
send "terminal more off\r"
foreach cmd $commands {
    expect $prompt
    send "$cmd\r"
}
expect $prompt
send "exit\r"
expect eof

Эта техника однажды становится более ценной вы добавляете обработку ошибок, а не доверяете всему, чтобы работать, так как одна из главных сил ожидания - способность ожидать нескольких вещей одновременно. Обычно это вам не нужно, но это суперценно когда вы это делаете!

Обычно вам не нужно добавлять вызовы sleep, а не когда вы просто отправляете команду в ожидании ответа.
