Question strange DNS


Hi list,

I have broadband connection with wi-fi modem. Have no issue in getting connected to the modem.
I have configured as DHCP and also DNS is said to be picked from modem.

here's my setup.

Modem ip: 192.168.1.1
DHCP starts from: 192.168.1.2

when my network is configured I get 192.168.1.2.. which is fine and the DNS gets updated
to 192.168.1.1. But this is not the actual DNS server configured. The modem has some thing
else..

with this setup.. when I do a ping linuxquestions.org. works fine, hostname resolved and
ping response is also seen.

But no other connection works; wget, telnet, ftp, lynx, gaim. all these fail to resolve the
hostname. When I update /etc/resolve.conf file with actual DNS. Everything works fine.

My doubt here is.. if DNS was the issue.. how is ping able to resolve the host...?

try pinging different hosts as your computer might have a dns cache...
or rather use dig instead...

What I mentioned was an example. Ping works fine for any hostname.. Sorry for being less clear on that.

considering cacheing on my system.. wont it suffice to all applications... I mean if google.com was cached.
And ping succeeds then it should succeed with browser too... Its not happenning...
