PPP for dial out is not working

Hi,

With Freebsd FreeBSD 9.2, I just signed up a very simple dial-up service to a local ISP. I have tested the line is working with Windows 7. But it doesn't work in Freebsd FreeBSD.

The ppp.conf is shown as below:
Code: 
default:
 set log Phase Chat Connect LCP tun command
 set device /dev/cuau0
 set speed 38400
 deny lqr
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" ATE1Q0 OK-AT-OK \\dATDT\\T TIMEOUT 40 CONNECT"
 #set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
 #          \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"

myisp:
        set phone 01198308100
        set login
        set authname saidid
        set authkey 20071967
        add default HISADDR
        enable dns
Here is the ppp.log message:

What 56K dial up modem suitable for FreeBSD?

Dear All,

Could anyone tell me what 56K dial up modem is suitable for FreeBSD 9?
I found all of them are built with USB, would this work with FreeBSD 9?
Can FreeBSD ppp or pppd configured to work direct with the Phone socket without a dial up modem? I tried Windows 7 without any dial up modem, and it works. I only used a phone filter which one end connect to the phone socket, another end connect the ADSL socket to the phone socket on the computer, and it works. But when I do the same for FreeBSD, it shown up "Chat script error".

Here is the content of the ppp.conf file:

Hi,

Does your computer have an internal or 'built in' modem?

I don't know. It is a Dell laptop, there is a built-in phone socket built in to it (just like all other laptop does).

Ok.

That Dell must have an internal modem if you were able to use the internet with the Windows setup.

Try to dial in with quotes in ppp.conf

Code: 
set authname "pppLogin"
Code: 
set authkey "MyPassword"

The code is from /usr/src/share/examples/ppp/ppp.conf.sample
 
The built-in modem is probably a Winmodem. There is no support for these any more on FreeBSD. Serial hardware modems will work, I've used them. USB hardware modems should also work, but I have not tried those.

But let's step back for a second. If you have DSL, why not connect Ethernet from the FreeBSD system to the DSL modem? That is much easier than dealing with PPP and dialup, and much faster also.

Hi thank you for your suggestion.
Where can I get a DSL modem that compatible with the 56k dial up service that provided by the isp?

Thanks

Sorry, I don't understand why there would be any dialup service on DSL. It's a digital line already, doing dialup over it is odd.

Isn't there a DSL modem in the house? Every one I've seen has both standard POTS phone jacks and an Ethernet port.

Hi,

I signed a 56k modem dial up service, I was given a phone number, login and password. Then I used these information to dial up from my Windows 7 without using any modem (just direct connect the phone socket on my laptop to the phone socket, and it works.

Now, I assumed it also works with freeBSD, but with the ppp.conf I got, it apparently does not.

In the past hour, I configured a DSL iConnect Access 621 modem in bridge mode, connect its ethernet port from the modem to the ethernet port on my freeBSD FreeBSD laptop. When I run the script with command ppp -ddial myisp, ppp.log shows this error:
Code: 
Network Unreachable

Here is the updated PPP configuration I use:

Code: 
# cat ppp.conf
default:
 set log Phase Chat LCP IPCP CCP tun command
 ##set device /dev/cua00
 set device PPPoE:bge0 # replace xl1 with your Ethernet device
 set speed 115200
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"

myisp:
 set phone 01198308100
 set authname saidid
 set authkey 200719677
 #set login "ABORT NO\\sCARRIER TIMEOUT 5 rname:--rname: ppp word: ppp"
 set timeout 120
 add default HISADDR
 enable dns

I can't really help you with this problem, but just to try and clarify something. The problem here is, as @wblock@ already mentioned, most likely your 'winmodem' or "software modem" ("softmodem").

The trouble is that it's not a real modem in the sense of a serial device which you can use to send specific AT commands to. Instead it's a very limited piece of hardware which doesn't necessarily respond to AT commands but instead is fully depending on the software to actually make it work. Or put differently; a normal modem ("MOdulator / DEModulator") "translates" computer signals into an audible signal, which can then be send across a phone line.

A Winmodem, or softmodem, usually relies on the underlying software (basically the drivers for it) to provide the actual modulation support. As such you need more than merely the classic AT commands to make it work; you actually need to tell it how to do it's job.

And considering that most of those drivers are closed source and haven't been actively shared by their manufacturers (not even on Linux) it's pretty much impossible to make it work on an operating system outside of Windows (which, obviously, does provide these drivers). And in general only because some hardware vendors thought the idea of saving on production costs to be quite appealing.

There are exceptions of course, but in general I've always approached winmodems with "Doesn't work outside Windows".

Does your laptop have a serial port? If it does you can get an external modem and not have to worry about drivers. USB or PCMCIA would work too.

You need to connect to the phone system. DSL is not the same a POTS.

Yes the laptop has a serial com port. But the DSL modem doesn't have one. Physically, how do I connect the COM port on my laptop to the phone socket? And do I have to recompile FreeBSD 9 kernel so that it include the following setting:

Code: 
options NETGRAPH
options NETGRAPH_ETHER
options NETGRAPH_PPPOE
options NETGRAPH_SOCKET

Thanks,
Sam

I think you are confused. First, DSL and telephone service are not related, except by using the same wires. The DSL modem is of no use to you whatsoever if indeed you wish to use a dialup account. You need a modem to connect to the telephone system.

As was explained earlier, the built-in winmodem is for MS-Windows only, and is not a real modem. Since you likely cannot replace it, the alternative is to add an external modem. This takes three forms. The traditional form with a serial port. You use a cable to connect between the serial port on your computer and the serial port on the external modem.

You can also get an external modem which connects with USB but I have no experience with these.

For laptops there is also the option to put in a PCMCIA card. I don't know if your laptop has these slots, but it is easy to get a modem that plugs in there.

It's actually very simple, I just think you got confused by the fact that the DSL modem plugs into the same wires as the phone. :)
 
Is this an external or internal modem? Try setting the speed to 115200 and test with cu(1) if you can send AT commands to the modem. It should, at the very least, respond to "ATI3" and "ATI4".

Try, as root, just dhclient bge0. If that works, there is no reason to mess with PPP at all.
