Setting up and using PPP
Note: A PPP package (such as ppp-2.3.5-1.i386.rpm) can be found on the instal-
lation CD-ROM or from ftp://ftp.redhat.com. The kernel should also have
TCP/IP support enabled.
To be able to set up and use PPP, you must have an Internet Service Provider (ISP).
The following information from the ISP is needed:
•
User name and password
•
Phone number(s) used to dial into the ISP's modems
•
The IP address assigned by the ISP (this is not necessary if the ISP dynamically
assigns an IP address each time you connect)
•
the IP address of the ISP's Domain Name Server. (Many ISPs have more than
one server. You need at least one in order to translate a URL such as
www.actiontec.com into an IP address, although you can still set up PPP without
it.)
There are many tools that make setting up PPP easier. This section explains some
basic ways to set up PPP.
Setting Up and Using PPP (Minimal Setup)
This section explains one way to set up a PPP connection from the command line. It
does not go into tools such as linuxconf or KPPP.
Step 1 The documentation for PPP comes with some sample dial-in scripts. They
are located under /usr/doc/ppp-2.3.5/scripts. Copy ppp-on, ppp-on-dial
and ppp-off into the /etc/ppp directory, which should have also been cre-
ated when PPP was installed. To copy the files, type the following:
cp /usr/doc/ppp-2.3.5/scripts/ppp-* /etc/ppp
and press ENTER. This must be done at root. ppp-on-dialer is a script
which calls the chat program, which communicates with the modem on
making a connection.
Step 2 Open up ppp-on in a text editor and make the changes to the parameters at
the top of the file. Also, at the bottom of the file, change /dev/ttyS0 to /dev/
ttyS4 and 38400 to 115200. Save and close the file.
