Dial Up problem in Ubuntu,dialing but not connecting...

[libbyz]

After managing to make my winmodem work, I can dial my ISP but I cannot establish connection using wvdial.
Here's the output of wvdial:

--> WvDial: Internet dialer version 1.54.0
--> Initializing modem.

--> The PPP daemon has died: PPP negotiation failed (exit code = 10)
--> man pppd explains pppd error codes in more detail.
--> I guess that's it for now, exiting
--> The PPP daemon has died. (exit code = 10)

The exit code 10 according to man pages means:
PPP daemon:
10 The PPP negotiation failed, that is, it didn't reach the point
where at least one network protocol (e.g. IP) was running.

However using dmesg I can see that all the required services run when the PC is booted:

# dmesg|grep IP

# dmesg|grep tty
...
[4294700.981000] ttyLTM0 at I/O 0xbc00 (irq = 10) is a Lucent/Agere Modem

I've also tried pppconfig, but when executing pon nothing happens! I've set correctly the modem setting...

I've read many posts,manuals,books, I have googled it but still can't solve the problem of connecting to the Internet. Does anyone have any ideas what might be wrong?

Thank you for your attention,
Libb

a guess, nothing more. You need to supply userid (usually in the form of "myname@myisp.com") and password to the /etc/ppp/chap-secrets and /etc/ppp/pap-secrets .

good luck

Unfortunately, this was not the case as chap-secrets and pap-secrets already contained my information in the form username * password.
I even installed SuSE Linux 9.3 and there I have a similar problem.
The difference is that I get as exit code 15 instead of 10.
I tried to connect via KPPP and here's what the error log contains after trying to connect to the Internet:

I think it looks like a driver problem, but the strange thing is that the same modem in another computer which has installed SuSE Linux 9.1 and the same driver works fine.
I might have missed to take care of some settings but I've done whatever I've read in manuals,forums and linux books and still doesn't work. Very strange,isn't it?
Any ideas?

[Nerderello]

yes, possibly is a driver issue. You can see from the log output that your TCP/IP software (ppp) is sending the startup packets out (the LCP stuff), but doesn't seem to be getting anything back. It could be that the driver is giving TCP/IP and PPP every indication that there is a valid connection, but this isn't really the case.

sorry I couldn't help.

Actually, it looks like you have it setup correctly, except you have to setup the configuration file /etc/wvdial.conf

As root, run

wvdialconf /etc/wvdial.conf

and enter your modem and ISP information. Then run wvdial, and you should get connected then. You can also run pull the man pages for wvdial.conf and wvdialconf for more information on getting wvdial to run correctly. I use it, and the only problem I have is that if I get disconnected, wvdial picks up the dial tone, but I can get the phone to hangup so I can redial.[/code]
