Hi! I have to connect to internet jumping wvdial.
Now i use wvdial and works with this configuration

ev56o,

wvdial starts pppd when the connection is established.

You need both pppd and some means of settng up the data link so that pppd can work.
There are GUI replacements for wvdial but I'm not aware of any pppd replacements.

I don' t want replace pppd.
I seen a lot of guide that shows a connection using pppd and no other programs.
These guides make a configuration for ppp and a command line start the connection.

Hello,

what you want is to convert the wvdial.conf to "pure ppp" scripts ?

I don't have the answer too, I would also like to use my 3G key without gas factories like NetworkManager...

Untested, but should work in theory:

/etc/ppp/peers/websfr

Gusar,

Thats cheating. You are just replacing wvdial with chat.
Chat is worth installing just to read the man page :)

XavierMiller,

Theres your hint ... chat or wvdial.

The gusar solution doesn' t work, i see the daemon pppd and chat work for seconds and dead, there isn' t log.

ev56o,

chat was what we used to use when 28k modems were new. I've probably not used it since.

You can make chat produce a log but its off by default as it records the username and password in clear text.
Its probably timing issues. You may need to add delays into the chat script so it doesn't execute too fast.
Like I say, its a long time since I used chat.

You can use ppp with a one liner and I have been doing it for years, I just didn't know. I use PPPoE

I don' t understand, do i have to use that command line with the configuration of gusar?

Gusar,

Its only pppoe because of the plugin it can be pppo<anything> with the <anything> plugin

Gusar,

The pppd man page says that pppd will shell out to chat to get the link up. It can be over serial or mobile phone or whatever. pppd calls chat for itself, given the one liners with all of the information. Its not without chat but its without visible chat.

I suppose I can test with my USB 3G dongle, which currently uses wvdial.

I use wvdial with huaveii e220 usb modem with sim card.
Finally we have to find the problem in the configuration posted from gusar, ok. Ho to do? I have non output or similar.

ev56o,
Gusars chat script is

Ok, i unconcommented the line ON and wait seconds, but don' t appean anything. With ps -aux i see there isn' t chat, pppd or pon process, i think of a crash. Is this normal? Do i have to wait along after launch pon?
I add an information, after launche pon (with non success) the modem don' t work neither with wvdial, i think in consqeuence of ATZ.

ev56o,

Emerge minicom and talk to the modem yourself, rather like talking to Bomb 20 in Dark Star .
To do this, you send AT commands to the modem. If the modem executes the command, it will respond OK
AT alone does nothing but the modem should respons OK
ATZ is reset.
ATH1 is go off hook
ATH0 is hangup
ATDT<number> is dial <number> using DTMF.
ATDP<number> is the same but with pulse dialing. Most modems ignore the P

You cannot start pppd this way as you can't type fast enough but talking to the modem and getting responses is a good first step.

I can' t use minicom because of a situation that requires use only pppd, i understand i can do this. How to do?

NeddySeagoon · Posted: Mon Sep 17, 2012 6:45 pm Post subject:

ev56o,

minicom will never get your data link up, which is what starts pppd. However, something, sometime has to talk to the modem directly to establish the link.
That something can be anything, minicom, chat, wvdial pppd, you can even assign a tty to the modem.

minicom is good for finding out whats wrong with getting the link up, if anything.
As a test, you can make the modem dial a phone number, your mobile phone, landline or whatever. If the phone rings, the test has passed.

I agree, you can'r use minicom for more than testing.

Your wvidal.conf said

I always have the devices

NeddySeagoon · Posted: Tue Sep 18, 2012 5:50 pm Post subject:

ev56o,

udev creates and removes /dev entries as devices come and go. When you unplug your USB 3G dongle, the /dev entries will vanish.
That the /dev entries are there indicates your kernel is in good shape too.

How do you know which device of the two devices is your modem?

Did you do the minicom test?

Is your normal user in the uucp group?
If not, only root can use those two devices.

The device is alwaya plugged, the device /dev/ttyUSB0 is indicate in the wvdial.conf, i use root always and i didn' t the minicom test yet.

NeddySeagoon · Posted: Wed Sep 19, 2012 7:27 pm Post subject:

ev56o,

I see that /dev/ttyUSB0 is in wvdial.conf. You also said that wvdial does not work.
We don't know why yet, thats what minicom will tell.
