modem operational but still no internet connection...

Hello !

I juste installed Arch, after some doc reading I figured out how to install the eagle-atm firmware (for my usb adsl modem)
now i have "modem operational" (dmesg).
I created a nice file in /etc/ppp/peers/ to descripe the provider (as found in various doc, on eagle-atm web site) but still, "pppd call my_provider_file" exits before even CHAP authentication...(although I have the proper chap-secret file)

here is what ifconfig tells me about ppp0 :

ppp0      Link encap:Point-to-Point Protocol
          POINTOPOINT NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

and that's the result of "route -n"

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0

I cannot figure out what's wrong ? Could anyone help me ?

Re: modem operational but still no internet connection...

See if the method I propose in http://bbs.archlinux.org/viewtopic.php?id=30172 when the usepeerdns option is passed to pppd can help you solve your problem.

Re: modem operational but still no internet connection...

I tried your script, but it dosn't make any difference.
I also have a running Kubuntu 5.10 on my machine, where the modem works (but with eagle-usb, not eagle-atm).
Here are the differences I have seen, maybe it gives a clue ... i don't know...

Arch pppd messages from /var/log/messages.log :

Maybe I have to set up something in the network of rc.conf ???

Re: modem operational but still no internet connection...

Here is what I have in /var/log/messages.log :

Feb 25 14:11:07 arch pppd[4987]: Plugin pppoatm.so loaded.

Can you tell what options you pass to pppd when you run "pppd call my_provider_file"
Tell also what you have in the files '/etc/ppp/chap-secrets' and /etc/ppp/pap-secrets'
You can post them but mask the passwords which may be in them.

Re: modem operational but still no internet connection...

my_provider_fils reads :

debug
user "0492764856@neufpnp"
plugin pppoatm.so 8.35
mru 1492
mtu 1492
noipdefault
defaultroute
usepeerdns
noauth
ipcp-accept-remote
ipcp-accept-local
nobsdcomp
nodeflate
nopcomp
novj
novjccomp
noaccomp -am
persist

but i tried several variants by commenting some lines...
I do not pass any other options to pppd

chap-secrets reads :

"0492764856@neufpnp" * "the_password" *

pap-secrets is (some comments removed) :

# INBOUND connections

# Every regular user can use PPP and has to use passwords from /etc/passwd
*       hostname        ""      *

# UserIDs that cannot use PPP at all. Check your /etc/passwd and add any
# other accounts that should not be able to use pppd!
guest   hostname        "*"     -
master  hostname        "*"     -
root    hostname        "*"     -
support hostname        "*"     -
stats   hostname        "*"     -

# OUTBOUND connections

#       *       password

what seems strange to me, is that it doesn't tell anything about CHAP authentication, either succeeded or failed ...

Re: modem operational but still no internet connection...

Here is what I have in the options file /etc/ppp/peers/ueagle-atm of the command 'pppd call ueagle-atm' which I use:

user "fti/AyYpV6k"
plugin pppoatm.so 8.35
noipdefault
usepeerdns
defaultroute
persist
noauth

In my file /etc/ppp/pap-secrets everything is commented out (I don't know if this is important).

As I see there is the option 'usepeerdns' in your options file for pppd, you have to write the DNS addresses in the file /etc/resolv.conf as shown in the other thread.
But the script /etc/ppp/ip-up will only be called when the connexion has succeeded, which seems not to be the case for you.
Has that connexion already worked ?
Is there a firewalll which prevent you from sending some packages on the net ?

not in Arch, but it works well with Kubuntu

"Is there a firewalll which prevent you from sending some packages on the net ?"
no

Re: modem operational but still no internet connection...

Do you run "pppd call my_provider_file" as root ?
Because on my machine the /etc/ppp/chap-secrets file is not readable under user login.
Apart from that I don't see why the connexion doesn't work on your machine.
Has you tried with only the options I use ?
Also try commenting out everything in the file /etc/ppp/pap-secrets.
Of course try always under root login.
That is all I can see for now...

Re: modem operational but still no internet connection...

You can also post in the "support for ueagle-atm" forum at http://forum.eagle-usb.org/viewforum.php?f=11

Check also your /etc/host.conf file, mine contains :

#
# /etc/host.conf
#

order hosts,bind
multi on

# End of file

and it is used during the connexion.
