Wvdial keep dialing and not terminating
 

Iam using two USB dongles in my desktop. I used to dial these dongles from ifcfg-ppp0 and ifcfg-ppp1.

Both are working fine but when we reboot the machine the USB port mapping modified for both dongles so that i got Authentication failure. But it is keep trying dial and not terminating...

How terminate the dialing if it got Authentication failure.

My ifcfg-ppp0 file

TYPE=Modem
DEVICE=ppp0
BOOTPROTO=dialup
ONBOOT=no
USERCTL=yes
IPV6INIT=no
PEERDNS=yes
AC=off
BSDCOMP=off
VJCCOMP=off
CCP=off
PC=off
VJ=off
LINESPEED=115200
MODEMPORT=/dev/ttyUSB0
IDLETIMEOUT=600
PROVIDER=ppp0
DEFROUTE=no
PERSIST=no
PAPNAME="username@revb.ttsl.in"
WVDIALSECT=ppp0
MODEMNAME=Modem0
DEMAND=no

/etc/wvdial.conf

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = #777
ISDN = 0
Init1 = ATZ
Stupid Mode = 1
Username = username@revb.ttsl.in
Password = password
Modem = /dev/ttyUSB0
Baud = 9600

So can we define the dial attempts to 3 and can we terminate if it got authentication failure

Thanks

Have you tried adding to /etc/wvdial.conf

I have tried Dial Attempts = 3 in /etc/wvdial.conf and maxfail 3 in /etc/ppp/option file as well. But still keep dialing even Authentication failed. Do we have any Dial attempts option on ifcfg-ppp1 scripts?

What happens if you set the number attempts and/or maxfail to zero?

Still keep dialing even after maxfail 0 and Dial Attempts = 0

/etc/ppp/options
lock
maxfail 0
