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

[kdj1@ticnet.com]

I am unable to connect to the Internet on my machine using Mandrake 
9.1.  LAN is fine, but internet connection is dialup and cannot ping.

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

What might I have misconfigured?  I would appreciate any hints or 
pointers to a solution.

Regards,

Dan F.

KPPP stats, ping results, netstat results, and ifconfig results are below.

KPPP executes handshake & connection,
KPPP statistics reports:
local address 207.53.228.68
remote address 206.176.148.90

Internet pings fail:

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

[user1 at localhost user1]$ ping 207.53.228.68
ping: icmp open socket: Operation not permitted

[user1 at localhost user1]$ ping 206.176.148.90
ping: icmp open socket: Operation not permitted

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

Lan pings work:
