[NTLUG:Discuss] PPP Internet connection problems - Mandrake 9.1

[Bobby Sanders]

I've had this problem.  I had to change some config file.  Don't
remember what it was, but do remember that I solved it by following
the stuff, step by step, in the following excellent paper.

Good luck.

  k> I am unable to connect to the Internet on my machine using

  k> cannot ping.

  k> Symptoms: KPPP functions normally and reports connection and IP
  k> addr.  Mozilla cannot find host.  Lan pings work, net pings fail.
  k> Netstat and ifconfig report same IP addrs as KPPP, so it appears
  k> to me that the connection is being made.

  k> ==================================== Internet pings fail:

  k> [user1 at localhost user1]$ ping www.yahoo.com ping: unknown host

  k> Pinging ISP DNS results in same 'icmp open socket' error msg.

  k> Lan pings work:
