pppdifficulties

["mmissett" <mmissett@cine-med.com>]

I have another mystery plaguing me here.  I seem to have the IP connection happening (to judge from plog), but am unable to connect to anywhere (to judge from ping) whether I use the URL (which gives me unknown host) or the numerical designation (which gives me x packets sent, 0 packets returned, 100% packet loss).  I have tried pppconfig a number of different ways and editing /etc/ppp/peers/provider, /etc/chatscripts/provider, and various other files manually, all to no avail.  It's pretty clear I've got hold of the wrong end of something, but I don't know what the right end is.  I could use all the help and guidance anybody has to offer.  Thanks,
Mike
