Why This script is repeat?
And How do I way slutioin?

The script seems to work
don't know why it fails then:

Quote:

daemon.warn pppd[88]: tcflush failed: Bad file escriptor
daemon.warn pppd[88]: tcsetattr: Invalid argument (line 1001)

look at the systems log-files for more info

add "debug" to /etc/ppp/options
if there is no useful info to be found in the logs

add te option "noauth" to /etc/ppp/options
because your provider will very likely not authenticate itself to you...

Or: use wvdial (set up "stupid mode") to connect

my script ( /etc/wvdial.conf ) looks like this:

Code:

[Dialer Defaults]
Modem = /dev/rfcomm0
Stupid Mode = 1

DialCommand = ATDT
Init1 = AT&FE0V1&D2&C1S0=0
Init2 = AT+CGDCONT=1,"IP","internet.eplus.de"
Phone = *99***1#
Username = eplus
Password = gprs

adapt to your device
(I'm using /dev/rfcomm0 because I connect using bluetooth...),
your modem-init-string ( the Init1 )
and provider ( the Init2 ) as well as username and password.

2. not replacing existing default route to eth0 [203.238.120.1]

I think this messages couse problem.
How do I modify script?
And wvdial.conf is only make at /etc?

jomen · 03-21-2006, 03:30 AM

wvdial is a different program to do the same task you try to accomplish with pppd and scripts here.
In my opinion it is easier to set up...

As for your error - check the systems log files or the ppp error log
They are in /var/log/... probably.
You might just have a bad connection - the line gets dropped by your provider - not by you or by pppd (that is what I see here).
