A good page about rp3 is located here.
rp3 is available on any RedHat system running RedHat 6.2 or later.
It is located on your GNOME menu under Internet- called
"Dialup Configuration Tool". It is perhaps the simplest to use
of the tools this HOWTO covers. When you start it up, it presents
you with a screen that looks like this:
Click "Next". If rp3 can't find a modem, it will try to confiugre one.
Select your modem from the list and click next if this happens. You should
see a screen asking for an "Account name" and a phone number. Enter your
ISP's name and number in the appropriate fields. Click "Next".
rp3 will then ask you for your username and password. Enter them
in the appropriate fields and click "Next". Next rp3 will ask you
if your ISP is named in a list. If it is, select it and click
next. If not, select "Normal ISP" and click next.
That's it! Click "Finish" to complete account creation.
To initiate a connection, go to the GNOME menu again, and look under Internet
for "RH PPP Dialer". Click on it. When asked for an interface, select
"ppp0". This should bring up a small window. Right click on the window,
then on "Connect to ppp0". Wait a few seconds, and you're online! To
disconnect, right click on the window again, and then click "Disconnect".
That's it.
