Recommended Posts

Взех на старо един 2950, но има някаква останала конфигурация, като има сложена явно и boot парола.Ето какво изписва/става когато се свържа през конзолния порт:

This computer system should only be accessed by authorised users who
have undertaken appropriate training.

Access by unauthorised users may constitute an offence under the
Computer Misuse Act 1990, for which they may be prosecuted.

The Data Protection Act 1998 applies.




User Access Verification


След което ме пита за Username, но без да натискам нищо ми въвежда само Username-a "Q1":

Username: Q1
Pass

% Aution failed.

Username: 1
Password:

% Aution failed.

Username: Q1
Pass

% Aution failed.

EDU-Haverstock-2950-1 con0 is now available

Press RETURN to get started.


И при натискане на Enter, всичко се повтаря.
Успях да вляза в рековърито, но дори и там спама с Q1 продължаваше.Въпреки всичко, тъй като има малко забавяне докато го въведе, успях да изпълня:

flash_init

после:

load_helper

При което изписа следното и всичко започна да се повтаря на ново.

Не отговарям на постове написани с шльокавица!
