Cisco 1751 ADSL

[spiegel]

Salve avrei bisogno di aiuto per risolvere su di un cisco 1751 con wic adsl.
Credo di aver impostato bene la configurazione ma non riesce a connettersi.
Qualcuno può aiutarmi?
Non riesco a trovare qulcuno che ne capisca qui dalle mie parti.Nemmeno il mio docente CCNA non sa risolvere questo tipo di questioni.
Grazie mille a coloro che vorranno aiutarmi.

[TeCer]

occorre che incolli la configurazione che hai fatto, altrimenti è un pò difficile aiutarti.

[spiegel]

Ok grazie.Eccola te la inserisco.Ti incollo anche il debug del PPP.Spero tu capisca il problema.
Mi da sempre errore username se ho capito ma la username è esatta in quanto se uso un router tradizionale (dlink) funziona perfettamente.
Ho una linea 7 mega solo dati tiscali.
Grazie Paolo

[lorbellu]

Ciao,

Quoto dal tuo post:

*Mar 1 14:54:53.719: Vi2 PPP: Phase is AUTHENTICATING, by the peer
*Mar 1 14:54:53.775: Vi2 CHAP: I CHALLENGE id 1 len 35 from "c72g1.rms-atm1"
*Mar 1 14:54:53.775: Vi2 CHAP: Using hostname from unknown source

*Mar 1 14:54:53.779: Vi2 CHAP: O RESPONSE id 1 len 27 from "Router"
*Mar 1 14:54:53.835: Vi2 CHAP: I FAILURE id 1 len 41 msg is "Authentication failed Unknown username"

La risposta sta nel debug, ovvero Authentication failed Unknown username

Il fatto é che nella configurazione del dialer hai usato il comando ppp chap username xxxxxxxx mentre per l'autenticazione via chap
(come sempre indicato dal debug) é richiesto di utilizzare l'hostname come username

*Mar 1 14:54:53.775: Vi2 CHAP: Using hostname from unknown source

Sostituisci il comando sudetto con ppp chap hostname xxxxxx e il gioco dovrebbe essere fatto.

Saluti

Ciao grazie per il prezioso aiuto! Sembra che sono vicino alla soluzione...
Ora mi da password errata anche se la password è corretta.Forse la sintassi della password non è corretta?
Ho dovuto anche aggiornare l'orario del router che nella connessione mi dava problemi (mi sa che devo cambiare la batteria,non tiene l'ora aggiornata,poco male)
Ti posto la nuova config aggiornata e il debug.
Mi dai una soluzione?
Grazie paolo

Ciao ho interrotto per un po la cosa che sono stato impegnato con il lavoro.

cosa posso fare?

[Wizard]

Ma sei sicuro che tu debba usare questo tipo di configurazione e non una con IP statico?

[spiegel]

Penso di si.Io non ho un IP statico nella mia connessione. Ho una linea solo dati tiscali con IP dinamico.Ti riferisci a questo?

[spiegel]

Sto ancora imparando e molte cose le prendo cosi come sono...
Se hai una configurazione ottimale magari commentata mandamela pure.
Mi basta semplicemente andare online senza access list,voip o altro.
Sto facendo esperienza
Grazie per l'interesse.

[spiegel]

mi sembra uguale a prima che dici?
Hai qualche idea?

[Wizard]

Sono 2 anni che nn configuro + un router adsl però da questo log:

No remote authentication for call-out

Mi sembra che non ci sia un server (radisu credo) che autentichi.
E' x questo che ti ho chiesto se eri sicuro...

Ma hai aperto una bella chiamata al provider?

[spiegel]

Ciao si ho gia chiesto a loro ma mi dicono che non possono aiutarmi x configurazione di apparati.
Però ora gli chiedo che server è utilizzato x l'autenticazione.
Ti faccio sapere.
