Problemi Reset Router Cisco 1801

[lanmau]

Ciao!

Premesso che sono un principiante...

Ho un Router Cisco 1801, usato e dovrei resettarlo e riconfigurarlo per utilizzare una connessione ADSL.
Il problema è che il precedente proprietario non ricorda nè l'ip, ne username e password di accesso.
Come faccio ad effettuare un reset se non posso collegarmi al router?
Esiste un reset hardware come sui router di altre marche?
Potete aiutarmi per favore?
Grazie

P.S. Ora riesco a connetermi al router tramite Hyperterminal, però sono fermo alla login, come faccio a scoprire username e password, oppure a resettarle entrembe?

[TeCer]

Segui la procedura di password recovery - http://www.cisco.com/en/US/products/hw/ ... 4773.shtml

una volta arrivato al router in modalita 0x2142 fai

enable
wr erase
conf t
config-register 0x2102
wr

e lo riavvii in modo da sbiancarlo completamente.

ho provato a spegnere il router e subito dopo averlo acceso a premere ctrl+pausa come descritto nella procedura, ma mi riappare sempre la richiesta di username e password

ho provato anche su due pc differenti (Xp e Windows 2000) sempre utilizzando Hyperterminal

qualche altro suggerimento?

posto tutta la sequenza a video:

Strano che non entri in modalità rommon, prova a premere più volte, e controllo che i dati di velocità e set dell'hyperterminal siano corretti.

Potrebbe anche essere che nel router, nella sua precedente config ci sia settato una velocità di baud differente.

[TeCer]

nella conf attuale c'è il "no service password-recovery"

http://www.cisco.com/en/US/products/hw/ ... 8113.shtml

There are only a few methods you can use to recover from a lost password, but all of them destroy the start-up configuration.

- Routers that have nonvolatile RAM (NVRAM) chips can be removed and reseated. The NVRAM is implemented with battery-backed up static RAM (SRAM). If you remove the SRAM, the contents of NVRAM are erased as well as the no service password-recovery configuration. Be sure to use proper anti-static procedures when you handle the NVRAM. Some of these routers are 3640 and 3660.

- Other routers, such as the 1700, 2600, and 3620, use an electrically erasable programmable read-only memory (EEPROM) in order to hold the configuration. The EEPROM does not erase when you remove it.

- Another method is to reload or boot the router with console access, and press CTRL-BREAK within five to ten seconds of the Cisco IOS software image decompressing or roughly when the "Image text-base:... " part of the banner begins. You are then prompted to reset the router to factory default (erase start-up configuration).

Ciao a tutti !!
Ho un 1801 come sapete .. ma ultimamente ho dovuto riconfigurarlo ma ho perso l'username/password doh...
