ubuntu not connecting to net

[blackleopard92]

And another problem has cropped up.I have ubuntu and hence Firefox as a browser.the problem is that Firefox doesn't connect to net.even GAIM(IM utility) doesn't connect to net.
I went to Networking and tried to ping www.yahoo.com, which it sucessufully did.
then, on advice of JGuru I went to the folder '/usr/share/applications' and click on "Networking'.
then Clicked on the tab 'Hosts'. then on 'Add' button.

This opens a dialog-box 'Hosts alias Settings' .
and typed this :
IP address : 130.94.75.250

Aliases : www.thinkdigit.com

Clicked the 'OK' button, Clicked 'OK' again to close the
'Networking' window.this time FireFox worked without any problems.

However, it's impossible to browse this way, Looking for IP addresses of every server that hosts files reqd for the page.and i can't do anything that requires internet.this includes synaptic package manager.

I have MTNL 590NU package. 256Kbps broadband connection, through DSL router.

Actually I don't face such problems. FireFox takes some time for looking up the
IP address of the site. But I can connect to the Net. @Blackleopard, if things
worked well in Kubuntu then you can very well shift to Kubuntu.

I get time out messages.

I also get this "unable to initialise HAL "eror at the startup, when desktop has loaded

[JGuru]

I think HAL error refers to networking problems. That's why you are
not able to connect to the Net. Did you modify any System Settings?
Or the Settings are the same.

@Blackleopard got it fixed. Just added the DNS Server IP address of MTNL and the
problem was solved.

PPP daemon has died = A modem hang up the phone (exit code = 16). Var/log/messages = warning: secret file /etc/ppp/papsecrets has world and/or group access.
