*RESOLVED* I can't get my dial-up connexion (airH) to work

Hi,

I am now in japan, and trying to use a system call airH" to get online. It is a pc-card dial-up modem using the mobile phone network instead of a simple telephone plug. the bandwidth is 128kb/s. Of course, this thing is shiped wth drivers for windows and mac OS, but they don't care about linux users.

So until now i have been trying to follow these two tutorials (japanese language):
http://www.deer-n-horse.jp/linux/gentoo/airh.html
http://takeposo.dyndns.org/unix/setting/airh.rhtml

But I can't get the thing to work. Maybe my japanese is too poor, and i missed something in the tutorials, but whatever the reason, I am stuck. Note that i am quite new to linux, so what i missed might be trivial.

As far as I understand i have managed with the hardware part of it. serial_cs kernel module is installed, and apparenlty working. after running "cardmgr" or "/etc/init.d/pcmcia start", the log corectly responds when Insert the ariH card.

Then I tried to set up the "/etc/conf.d/net.ppp0". I must have done it wrong, because when I run "/etc/init.d/net.ppp0 start" the system says it started properly with a nice green OK, but nothing happens. It does not seem to try to establish the connexion, and takes no time for dialing. and obvisously, internet is not working. When I run "/etc/init.d/net.ppp0 stop", i am told that the interface is already down.

I don't know if that is relevant, but i am running 2.6 kernel, on x86 platform. please also note that i curently have no other connexion that this airh thing (which works properly under windows).

any idea?

I'm not familiar with this driver type, but wit ppp im familiar.

But this kind of error smells like ppp having problems with it's config.
So for me, the first thing would be to look into the syslog, but before doing this, add two lines to your ppp options file:

here it is:

pppd[20542]: remote IP address 10.112.112.112

It seems that I get an IP. I am quite suprised about that, since it takes absolutely no time to dial.

Anyway i tried to ping something to see. I can't ping urls, since i don't have a dns, and i tried some ips, and got no answer.

I hope that this log will help you understand.

Hi falcon_za

The IP-Number you see is auto-assigned by pppd because you did not specify any other adress. If you know the called computers ip, you may assign some adress for your and the other computer, but it is better to let ppp do that.

delfault route was already on.

one of the thing that might have been bugging me was "demand", since it said the modem shouldn't try to connect except if needed (and how exactly it dermines that, i don't kno), so i took it out

now it tries to connect

It first sends "ATZ", and gets "OK" as excepted. then it sends the phone number and gets "no carrier", which is obviously not what we want. it just stop here, and no matter how many times it retries, it never can get a carrier.

What do you think might cause that?

falcon_za · Posted: Fri Sep 17, 2004 11:51 pm Post subject:

I am not sure how much this can help, but just in case. since i have no carrier, i guess something must be wrong with initialisation, maybe in the initialisation string.

Here is some information I took out of the windows driver. I am not sure exactly how to interpret it, and if this is standard initialisation string, or if i need to change my config files to take this into account. anyway, here it is:

Can you understand what this says?
Regarding the diffrent possible connexion speeds, i subscribed to the 128k.

There were some real stuff going wrong, and you helped fixing.
also, knowing about the dump command proved usefull

But the last step which was preventing me to get online was.... a stupid mistake. I forgot the leading 0 in the provider phone number. shame on me.

Anyway, That wasn't the probleme in the first place, since it didn't even try to dial, so this thread really helped me, but that should prevent me from being more carefull when i type in some text.
