Internet access problem with Debian Sarge + BSNL Dataone

[K MS]

Hi,
    Kindly help me get my first browsing experience in Debian linux.
I have tried various list-archives recommended by Google still have
not been able to get around fixing this.
    Email below is rather long. I have explained my installation
and shown the logs before asking my questions at the bottom.

  I have installed Debian GNU/Linux, Sarge 3.1r0a on my PC along
  with Kernel version 2.6 686.
  I also have the dataone broadband service from BSNL (in bangalore,
  INDIA).
 
  I logged in as root and started ADSL/pppoe configuration as root
  (/usr/sbin/pppoeconf) and answered the questions. Entered user-name
  and password - but I didn't get a question for which I could enter
  the DNS server names in response..
 
  To clarify further, I did not additionally install rp/pppoe or any
  other software on top of the installation.
 
  eth0 contains a LAN card. This was detected during installation and the driver
  was automatically loaded. The ethernet connection is active and ifconfig on
  restart/startup is as follows:
  eth0      Link encap:Ethernet  HWaddr 00:05:5D:4B:1E:85
            inet addr:192.168.1.34  Bcast: 192.168.1.255  Mask:255.255.255.0
            inet6 addr: fe80::205:5dff:fe4b:1e85/64 Scope:Link
            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
            RX packets:140 errors:0 dropped:0 overruns:0 frame:0
            TX packets:175 errors:0 dropped:0 overruns:0 carrier:0
            collisions:0 txqueuelen:1000
            RX bytes:11877 (11.5 KiB)  TX bytes:15003 (14.6 KiB)
            Interrupt:209 Base address:0xc400
 
  When I run pon and then plog I get the following output.
 
  plog output (copy-pasted from /var/log/syslog)

  Dec 23 21:57:24 localhost pppd[4728]: secondary DNS address 61.1.96.69
 
  The DNS server addresses are worrying because the address reported
  in the log as secondary is exactly what I supplied to pppoeconf as
  the *primary* DNS address. The primary reported in the log output
  doesn't ring a bell at all...
 
  After the first time I ran pon the file /etc/resolv.conf contained
  the primary and the secondary nameserver addresses as per the log
  above (218.248.255.145 & 61.1.96.69).
  When these were edited to be 61.1.96.69 & 61.1.96.71 (the correct
  values supplied by ISP), the log still showed the same output and
  nameservers were the same (they get reset!).
 
  Some other information...

Questions
Now the basic question is has it been able to connect ?!
Although I don't see any error messages in the log, ping for any ip results in an
error message: "net is unreachable" and I am not able to access the web via
Epiphany / Konqueror.

If not, then how to correct this problem and verify if it has connected properly ?
Once pppoe connects is there something extra that needs to be done to access
the web from my desktop ?
