[Tech] pppd e script per connessione.

[Lorenzo Cocchi]

Vorrei connettermi con il mio modem ext analogico usando "pppd" e "chat"
Ho modificato il file /etc/ppp/options inserendo le seguenti righe:
#/etc/ppp/options
lock
defaultroute
noipdefault
modem
/dev/ttyS0
115200
crtscts
passive
asyncmap 0
-------------------------------------------------
Poi ho creato lo script /etc/ppp/pppscript inserendo le seguenti righe:
#/etc/ppp/pppscript
TIMEOUT 60
ABORT ERROR
ABORT BUSY
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
"" AT&FH0"
OK "atdt0553801010"
TIMEOUT 75
CONNECT
-------------------------------------------------
Dopo ho modificato /etc/ppp/pap-secrets
"mionomelogin"	*	"miapassword"
-------------------------------------------------
Come "root": 
/usr/sbin/pppd -detach connect "/usr/sbin/chat -v -f /etc/ppp/pppscript"
Riporto il log della connessione:
