Thanks for your response. I have Fedora Core 1 on 2 other computers but get the same error: The ASDL connection appears to be activated, an IP address appears to assigned by the internet provider but none of my browsers (Opera 7.23, Mozilla 1.5, or Konqueror) are able to connect to any site.
Please note that there is no proxy server so each browser is configured as a direct connection to the Internet. Also, there is no problem connecting with Knoppix 3.0--Nov 2003 release nor with WinXP Professional.
This is the output of ifconfig -a:
