Re: unable to connect with internal modem under Ubuntu

Devon,

That prompt after a username and a password which went through:
--> Hmm... a prompt.  Sending "ppp".
> > ppp
> > 'ppp' is not a valid command.
is definitely abnormal.

I cannot figure out how access can be free with a universal password and 
username while the dialog shows:
>>> CVX Access Switch.
>>> Access is restricted to authorized users only.
Do you have any idea about what this CVX means?
What is your ISP?
In which country?
Could it be that after having having accepted the username and password 
the ISP waits for something else?

What happens if you add this line in /etc/wvdial.conf  (say near rhe end)?
Stupid Mode = yes
What this one does is to make YOUR modem immediately request an Internet 
connection rather than waiting for THE OTHER SIDE to take control.
Since the other side sends a prompt perhaps Stupid Mode will make 
everything work before that prompt.

I am sorry to be inefficient here: you are using wvdial version 1.60 
while I stick to 1.54 because of an other unrelated bug in 1.60.
As far as I know, wvdial should day   pppd  , not ppp.

What happens if you say
sudo find / -name pppd
and then
sudo find / -name ppp

Thanks for such extra info.

Jacques,

Thank you for your help.  I just disabled the Login line (so it now looks like ";Login = guest") and re-ran wvdial.  I got the same report as I appended earlier -- wvdial sent "ppp" and so on.

Devon,
Before I invest more effort, would you please remove (or
disable by introducing a leading semicolon ; ) the Login
line in /etc/wvdial.conf, and just start wvdial again?
I have never seen that 'ppp' before, the Login line
possibly caused (and revealed) a bug in wvdial.

Jacques,

Thank you very much for your reply!

I thought I had edited the wvdial.conf file
appropriately, but apparently I had not.  I fixed the error,
and tried wvdial again.  It connected with the ISP but
couldn't get past some prompts.  The ISP is free
(NoCharge.com) and has a universal login/password.  I've
appended below the output from wvdialconf, the contents of
the wvdial.conf file, and the results from my latest attempt
with wvdial.  Would the scanModem ModemData.txt output still
be helpful for you to have?
Thanks again,

The  right way to proceed is indeed to use wvdial
but before
you use
wvdial you must configure it using wvdialconf

First you   sudo wvdialconf /etc/wvdial.conf
If your driver is correctly loaded wvdialconf will
write a
skeleton file
/etc/wvdial.conf
You must edit that file where the line
;Username = <your username>  should become
Username = what_the_ISP_told_you
and the same for Password and Phone number
Note that the leading ; has to be removed.

Once this is done wvdial should establish the
connection.
If you have any problem, please send us:
1-the scanModem output (see
http://linmodems.technion.ac.il#scanModem )
2-the file /etc/wvdial.conf AFTER ERASING YOUR
REAL ISP
PASSWORD (this, because you certainly do not want
to make
the password public...)

The error message " Configuration does not
specify a
valid login name."
does unequivocally show that either you did not
run
wvdialconf or you did not edit it or you forgot to
remove
the ; at the beginning of the line ;Username (and
possibly
the other: Password, Phone number, as well)

I am new to Linux and Ubuntu. I recently took
a
Pentium IV PC in very
good condition running Vista, and successfully
installed Ubuntu 8.04
to the whole disk (no partition with Vista).
My final
task is to get
the internal modem working (I’m preparing
this
machine for someone
who has dialup internet access only).

I’ve been unable to connect to the internet
with the
modem, and I’m
posting to seek help. I’ve searched the
Ubuntu
Forums Networking and
Wireless board for relevant threads and
followed
various instructions
for configuring and running the modem. 
Yesterday I
posted to the
Ubuntu Forums board but haven't received
any
replies.
Here’s what I’ve done:

I know the phone jack and dialup ISP both work
–
I’ve used both with
a Win XP machine’s internal modem (with very
quick
configuration).
I first ran scanModem and found the necessary
precompiled drivers
(hsfmodem_7.68.00.14full_i386.deb) at
linuxant.com. I
downloaded,
extracted, and installed the drivers.

I tried the Network Admin, wvdialconf/wvdial,
and
pppconfig/pon
approaches described at

https://help.ubuntu.com/community/DialupModemHowto/SetUpDialer#head-f5120acdc3ef62fe7d37bfd3f0c9157ebe9c8ef
and

http://www.ubuntugeek.com/setting-up-dial-up-connection-in-ubuntu.html.
When I tried to connect with the Network Admin
approach (using the
network connection icon at the upper right of
the
Ubuntu desktop >>
Dial-up connections >> Connect to ppp0
via
Modem), nothing happens.
When I tried connecting via “sudo wvdial”
in the
terminal, I got this
error message: ~$ sudo wvdial --> WvDial:
Internet
dialer version
1.60 --> Initializing modem. -->
Sending: ATZ
ATZ OK --> Sending:

V1 E1
S0=0 &C1 &D2 +FCLASS=0 OK --> Modem
initialized.
 Configuration does not specify a valid
login name.

The login name is accurate, because I used it
successfully on the
system running XP.

When I tried to connect via pon (after
configuring
with pppconfig), I
got this error message: Dec 15 12:40:16
carolyn-desktop pppd[6450]:

Exit.

This is apparently the same problem that
responder #11
in this thread

(http://www.ubuntugeek.com/setting-up-dial-up-connection-in-ubuntu.html)
had, but apparently there was no further
discussion of
his problem.
I am at a loss for what to do. I can provide
full
output from the
scanModem run and wvdialconf if that would
help with
diagnosis. I’d
prefer a GUI for connecting because the person
who
will use this
system has limited computer skills/experience.
I was
able to download
gnome-ppp (apparently not in the Ubuntu
repository)
but couldn’t get
it to be installed or operate.

The system is perfect except for this dialup
problem.
Any help or
advice would be much appreciated.

Thank you!
