Titolo: 1721 che si collega alle sedi  in modalità random

in un centrostella ho un 1721 che si occupa di gestire le
comunicazioni con diverse sedi remote.
2 di queste sedi sono connesse mediante seriale isdn.
quando una delle sedi chiama il centrostella tutto fila liscio il
problema si pone quando io inserisco il numero della sede remota nell
dialer il router chiama in modo random.
posto un log per capirci meglio

cosa posso usare per sapere il motivo di questa continuo ip end dpwn
dell'interfaccia   ???
come posso capire quale programma cerca di accedereall'esterno.......
grazie  a tutti

 della dialer-list... sei sicuro di averla ben fatta ??
con aggiunto un bel debug dialer event e, se proprio vuole, un post 
della configurazione purgata delle password

Ancora meglio un bel "debug dialer packets".

tutti i debug che ho eseguito, danno come risultato  gli stessi log.
quello che vorrei capire č:
- quste chiamate vengono eseguite da una applicazione che cerca di
accedere alla sede remota ??? se si come faccio a capire quale ......
_ non č possibile vedere da quale macchina arriva la richiesta di
collegamento ???
- il router ha percaso un parametro di esistenza in vita ???   ipotesi
 che in maniera random cerca di capire se le sedi remote sono
raggiungibili.
per il momento nella stringa della dialer non ho inserito nessun
numero .... appunto per evitare collegamenti indesiderati "come č
successo in passato" ciň nonostante il router alza e abbassa il canale
mediamente 5 volte in una notte......  le stringhe che genera in quel
momento sono queste:

grazie ragazzi.

 tutti i debug che ho eseguito, danno come risultato  gli stessi log.
Impossibile: hai fatto un terminal monitor?
Se l'hai fatto, devi vedere l'ip sorgente che triggera la chiamata.
Posta la configurazione.

 grazie ragazzi.

Non č che la borchia alla quale hai attaccato il router č una nt1+ che ha
collegato anche un fax o qualche altro dispositivo analogico?
Il router logga ogni volta che la linea va up e down, a prescindere dal
fatto che la chiamata sia da/per il router stesso, quindi anche da altri
terminali collegati alla stessa borchia, mi sembra proprio il tuo caso.
D'altronde se non hai impostato nessun numero nella dialer č impossibile che
il router generi una connessione, sia regolare che abusiva .... a meno che
non si chiami mandrake!!!!

Verifichero, omunque anche se la dialer non contiene nessun numero
l'inizializzazione della bri dovrebbe avvenire, e poi in mancnza del
numero la bri va in down ......  ovviamente è una mia deduzione, ma
potrei sbagliarmi.
Il problema è che in realtà non capisco in tutto per tutto il log
quindi le sparo un po tutte.
Ho anche modificato l'antivirus sul server e sui client pensando che
fosse il norto che contattava i client ........
non so piu dove sbattere la testa 
grazie tosh, se ti viene in mente qualche cosa ..... sono tutto
orecchie  "occhi".

 potrei sbagliarmi.
In mancanza del numero la bri è attivissima, semplicemente non può chiamare
perchè non sa chi chiamare, ma può ricevere tutte le chiamate che vuoi.
I log che hai postato indicavano che in determinati momenti il layer2 è
diventato attivo, cosa che può semplicemente indicare che c'è stata una
chiamata (anche analogica, anche non risposta) verso il/i numero/i della
borchia, oppure che è partita una chiamata da un'altro dispositivo collegato
alla borchia (fax?), oppure semplicemente si tratta di reset programmati
della borchia da parte della centrale telecom.
La conferma sta nel fatto che i debug che ti abbiamo suggeritodi impostare ,
come confermi tu in un post precedente, non danno alcun output (almeno la
notte, mentre di giorno dovresti vedere tutti i dettagli delle chiamate) e
ce l'avrai ancora di più analizzando la prossima bolletta.

grazie a tutti.


Se non hai eccessivamente purgato la config direi che non c'è nessuna
possibilità che questo router faccia delle chiamate, non solo non ci sono
numeri da chiamare, ma non hai nemmeno configurato il traffico interessante.
Per quanto riguarda i log si riferiscono tutti a traffico di livello2 che,
come ho già detto, potrebbe benissimo riferirsi a chiamate di altri
dispositivi o traffico di "servizio".
Ciao,
        Tosh.

 grazie a tutti.
