Hello,
I've a Debian etch system connected to the web through a GPRS/UMTS
PCMCIA card. I'm using pppd to connect it to the ISP. However, I see
quite a lot of connection failures (connection establishment has to be
tried quite a few times before it succeeds), and even worse, the
connection often succeeds, but with bogus DNS servers IP's supplied
(10.11.12.13 and 10.11.12.14), rendering it useless.
I've looked through the archives
(http://www.opensubscriber.com/message/linux-ppp@vger.kernel.org/7889888.html),
and found that the bogus DNS problem has already been seen when the
peer insists on wins servers, but this is not the case here.
So I suppose that there are some differences between the various peers
available by the ISP, and that only some of them accept the way "my"
pppd deals with them, but I've no idea about how and what to change to
increase the success rate and most importantly avoid this bogus DNS
problem.
I've attached below 3 typical pppd log:
-first is a successful connection.
-second one is a successful connection, but I get the bogus DNS servers
-third one is a failed connection
Any hint would be very welcome.

G'day,
This is common. There exist many implementations. The "modem" device
contains firmware that invents DNS server IPs and presents them to the
host before the radio network has provided them. I see 10.11.12.13 and
10.11.12.14 quite often.
(The modem firmware is the PPP peer, acting as a protocol translator to
the radio network, and is not compliant with the RFC, in my opinion).
This delay in providing IP addresses can be caused by either:
1. invalid access point name (APN), set by AT+CGDCONT ... which causes
the modem to not receive any reply from any access point on the
provider's network,
2. incorrect profile set, causing incorrect APN to be used,
3. refusal of the provider's access point to send an IP address,
4. use of incorrect username and password, (it is reported by the modem
as valid before it is checked by the radio network),
5. incorrect username and password set on modem, (for some reason the
modem can also keep the username and password in AT commands),
6. use of incorrect authentication method (PAP vs CHAP),
7. modem has not yet finished attaching to the radio network, because
there is no signal, or too much radio noise,
8. modem has not yet finished attaching to the radio network, because
the radio network is congested,
9. modem has not yet finished attaching to the radio network, because
it was only just powered on.
There is very little that can be done to isolate to the exact cause, at
the PPP level.
One method to decrease the probability of the normal delays (7, 8 & 9)
is to ensure the modem is attached to the radio network before you begin
a connection. This is what I do in the eee-maxon-bp3 package, the
/etc/chatscripts/bp3 file contains:
# cease if modem is not attached to network yet
ABORT '+CGATT: 0'
'' AT+CGATT?
And the invokation of pppd fails, and is retried by a shell script,
until the modem advises successful connection.
This does not eliminate the problem, but it certainly reduces the
frequency of it. Happy users.
I was going to add an option to pppd that would detect this particular
buggy peer and persist with obtaining a valid DNS configuration. But
this workaround was sufficient.

Attached is patch I made for my GPRS modem with the same problem.

I don't understand why this would help. Can you show me the log for a
successfull connection with this patch applied (using the debug
option)?
