MTN + Nokia N95 + Data cable + Linux (Calling all Linux gurus)

[neonpill]

(Please excuse the long post, I have tried many options already, and this is the fruit of my frustration.)

I have recently, courtesy of iTalk Cellular, come into the possession of THE AMAZING, THE INCREDIBLE, DEFENDING CHAMPION OF THE WORLD TITLE Nokiaaaaaaaaaaaa... N95! One of the great features on the phone is its 3G (HSDPA) capabilities, which I would like to extend to make use of on my computer by using the "phone" as a modem.

Note: I am using Arch Linux as my operating system, so I can't get Nokia to do everything for me w.r.t. software - I must configure it myself.

The phone appears as /dev/ttyACM0 (udev). I haven't gotten it to register with the correct user credentials (it auto-assigns as root:tty for some reason, with restricted priviledges too), but for now I can wangle it my chowning and chmoding as needed.

I connect using wvdial. It seems to work, as I can ping the MTN DNS servers, but DNS itself doesn't seem to work! I.E. when I try to ping a DNS address, (such as mybroadband.co.za) it works. It could be my routing, as I have not managed to ping the one IP address that I have memorized (my company's webserver) either.

Here follows a log of my activities:

What must I do to get DNS working?!!

Thanks

wvdial is writing the DNS servers to /etc/ppp/resolv.conf instead of /etc/resolv.conf (http://wiki.linuxquestions.org/wiki/Wvdial).

to fix this, you could probably create a symlink:

mv /etc/ppp/resolv.conf /etc/ppp/resolv.conf.backup
ln -s /etc/resolv.conf /etc/ppp/resolv.conf

 

[neonpill]

Thanks, andres101. I have created a symlink in /etc to /etc/ppp/resolv.conf before (since it can potentially be re-configured every time I connect) and that didn't seem to work. I will try putting the addresses in /etc/resolv.conf directly. Which DNS servers should I use?

 

[andres101]

i think it is the MTN NS name servers:
nameserver 209.212.96.1
nameserver 209.212.97.2

 

[andres101]

sorry about the 2nd post and deleted post... I tried to keep the thread 'clean'.

I just checked my system and I have /etc/ppp/resolv.conf and /etc/resolv.conf. Their timestamps are the same, which leads me to believe that pppd is updating /etc/resolv.conf for me.

this is confirmed in the man page (man pppd). the DNS servers are passed to the /etc/ppp/ip-up script, which updates /etc/resolv.conf.

Woo! I am posting this response from my freshly connected via N95 linux box. I think I had everything in order already, but I copied /etc/ppp/resolv.conf over /etc/resolv.conf anyway.

I have no idea why I could not get connected up to yesterday, but it works great now. Thank you very much for your assistance, I will go read up on the references given.

They were upgrading the e-mail server, helluva nightmare for interent usage
