Before running pppconfig you should know what sort of authentication your isp requires, the username and password that they want you to use, and the phone number. If they require you to use chat authentication, you will also need to know the login and password prompts and any other prompts and responses required for login. If you can't get this information from your isp you could try dialing in with minicom and working through the procedure until you get the garbage that indicates that ppp has started on the other end.

B<pppconfig> allows you to configure connections to multiple providers. For example, you might call your isp 'provider', your employer 'theoffice' and your university 'theschool'. Then you can connect to your isp with 'pon', your office with 'pon theoffice', and your university with 'pon theschool'.

It can determine which serial port your modem is on, but the serial port must already be configured. This is normally done when installing Linux.

It can help you set your nameservers, or, if your ISP uses 'dynamic DNS', it can set up ppp to use that.

It can configure ppp for demand dialing, so that your ppp connection will come up automatically. It will not, however, start pppd for you. You must still start pppd yourself ('pon' will do it). Pppd will then wait in the background for you to attempt to access the Net and bring up the link.

If you select "Static" in the "Configure Nameservers" screen pppconfig will create a file in the /etc/ppp/resolv directory named after the provider you are configuring and containing "nameserver" lines for each of the IP numbers you gave. This file will be substituted for /etc/resolv.conf when the connection comes up. The provider name is passed in the ipparam variable so that 0dns-up knows which file to use. The original resolv.conf will be put back when the connection goes down. You can edit this file if you wish and add such things as "search" or "domain" directives or additional nameservers. Be sure and read the resolv.conf man page first, though. The "search" and "domain" directives probably do not do what you think they do.
