Redhat 4.01, ppp, and ISP connectivity

To whoever can answer:
Last summer, running Slackware 2.*, with kernel 1.2.1, I had *no* trouble connecting to my ISP through linux.  This year is different however.  I have tried everything, but I can't get pppd to connect when my ISP begins sending PPP packets after a login.  It just spews packets for a while (my isp, that is) and then drops carrier on me.  Can anyone help?  I've tried as myself, as root, and tried a lot of different options (silent, passive crtscts, etc) to get it to go.  Also, my ISP uses no authentication on their side, and my options file does exist in /etc/ppp/, like what was suggested to me.  Thanks,

Since you're using redhat, you can use 'netcfg'.  It can be found in 'control-panel' or invoked directly.  It will allow you to set up everything you need to connect (except the link to /dev/modem which you must already have).  Simply add a ppp interface, a route for that interface, and a name server.  Then you should be able to "activate" that interface and let it dial on in.  Plus, it's nice to look at and easy to use. :)

The scripts that netcfg uses, are in /etc/sysconfig/network-scripts, if you don't use X-windows.  A file will be set up for each interface called ifcfg-ppp0 (or ifcfg-eth0 or ifcfg-ppp1, etc.).  You then invoke ifup-ppp with the interface as an argument to dial:

bash $ ifup-ppp ifcfg-ppp0

This will handle ppp for you, redial if disconnected, etc.  

bash $ ifdown-ppp ifcfg-ppp0'

      will then disconnect ppp0.

I think that covers most of the standard stuff :/
Keep me posted.
