cannot find canonical DNS on slmodem PPP connection

I have a strange problem on a PPP connection. I am using slmodem (logging in
from India) on travel. I get through fine, using slmodem on my PCTEL modem, and
get the following, but get a can not find canonical DNS. Hence I can not
connect to the web using linux. Any suggestions?

By the way, here are some details:

$ ifconfig 
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:10 errors:0 dropped:0 overruns:0 frame:0
          TX packets:10 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:708 (708.0 b)  TX bytes:708 (708.0 b)

ppp0      Link encap:Point-to-Point Protocol  
          inet addr:61.2.0.216  P-t-P:61.0.128.83 Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:7 errors:0 dropped:0 overruns:0 frame:0
          TX packets:80 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3 
          RX bytes:302 (302.0 b)  TX bytes:5710 (5.5 KiB)




Also, this is the transaction when I used wvdial:

And I get the following when I use fetchmail:

.......
fetchmail: couldn't find canonical DNS name of mailserver
 
When I use firefox or dillo, I also get the same thing. When I try to ssh out
to my work machine, I get temporary failure in name resolution.

Any suggestions/help? Btw, I am running Fedora Core 4 and the latest version of
slmodem.

Many thanks and best wishes!
Globe.
