hi, all:

I used to have a healthy working PPP connection.  Now everything goes slow
and the connection is bad.  I lost connection more than ten times
yesterday.

There is nothing wrong with ISP side.  I checked it with a Windows machine.
It run as fast as what I had before.

Here, I bring up this question: how can I check on a ppp connection. I mean
how can I find which part goes wrong, hinders whole connection.  I dont
remember I changed any NETCONF.  

I observed that there were more traffic than normal fetchmail should have 
even when I stopped all ftp and web software. 

Could you shed some light on it?

TIA,

Weizhong

netconf: config ppp connection
