gprs through usb mobile phone - i386 works / amd64 not

[Cem Kayali]

Hello!

I have a mobile phone (modem) and i was able to connect to gprs network
through KDE's kppp dialup tool (on NetBSD 4.99.5X i386) such that:

Modem device: /dev/ttyU0 or /dev/ttyU1
Flow control: Software
Line term: CR/LF
/etc/ppp/options: noauth



Now, i am trying same configuration (on NetBSD 4.99.69 amd64) and it
even does not query modem, window is closed once i click on 'query
modem' option.

No error message in kdm.log, messages.


dmesg output is as

umodem0 at uhub0 port 1 configuration 1 interface 1
umodem0: Sony Ericsson Sony Ericsson, rev 2.00/0.00, addr 2, iclass 2/2
umodem0: data interface 2, has CM over data, has break
umodem0: status change notification available
ucom0 at umodem0
umodem1 at uhub0 port 1 configuration 1 interface 3
umodem1: Sony Ericsson Sony Ericsson, rev 2.00/0.00, addr 2, iclass 2/2
umodem1: data interface 4, has CM over data, has break
umodem1: status change notification available
ucom1 at umodem1


I apprieciate if someone has advise. This is crucial for me once i am on
a trip.

Regards,

This is probably a kde issue. How about using tip to connect directly to
the serial device and sending it AT commands to check for connectivity?

If connectivity is fine, you could always fall back to using pppd/chat
instead of kppp.

I have also configured /etc/ppp files to use command line connection:

pppd call CONN_NAME

This does not produce any output or error message either.


'kdump ktrace pppd call CONN_NAME' produces 2000 line output :)

OK, i able to connect to modem (that's what ifconfig -a claims) but no
connection really.

I think i  need to work on connetion script somehow:


ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
        inet 211.41.111.111 -> 10.64.64.64 netmask 0xffffff00
        inet6 fe80::21b:38ff:fed7:d3af%ppp0 ->  prefixlen 64 scopeid 0x6

It should log to syslog; did you have a look there?

This problem is probably KDE specific; I can establish a GPRS link
using my cell phone as a USB serial modem just fine on NetBSD/amd64
4.99.70.

What's the default route? Is your /etc/resolv.conf set up correctly? By
default, pppd only creates a file in /etc/ppp/resolv.conf, not directly
in /etc.

Thanks for tips.

OK, i noticed that the problem is with /etc/ppp/resolv.conf, but
situation is vice versa. Copying it to /etc/resolv.conf didnt work,
probably there is a problem with gprs provider nameservers. I inserted
opendns nameservers

nameserver 208.67.222.222
nameserver 208.67.220.220

and it worked.



Result: The problem is KDE specific, Yes.

Regards,

Result: The problem is KDE specific, Yes. There is a open bug report in
kde.org, stating that kppp crashes on FreeBSD amd64 system while it
works on i386.
