PPPD Configuration
  1. Ensure that your kernel is compiled with PPP support. This can be done either as a module or as a compiled-in driver. If you are not certain, cd to /usr/src/linux and do 'make menuconfig' and go through the Networking sections to be sure that PPP support is configured. If you choose to make this a module, do not forget the 'make modules' and 'make modules_install' steps after the main kernel image has been compiled. If you are not familiar with kernel compilation, read the Kernel-HOWTO.
  2. You need to place two files in your /etc/ppp directory. This must be done as root. First, you need to overwrite your /etc/ppp/options file with this one. Then you need to add the scriptfile. The files given here are generic; you should edit /etc/ppp/scriptfile to add the username, password, and phone number you will be using and the options file assumes that a symlink /dev/modem exists. If it does not, cd to /dev and create it. COM1 in Windows is /dev/ttyS0 in Linux, COM2 is /dev/ttyS1, etc. Type 'ln -s /dev/ttyS1 /dev/modem' to create a symlink called /dev/modem that points to a modem on COM2.
  3. Be sure to do 'chmod 755 /etc/ppp/scriptfile'.
  4. Next, we need to configure DNS. This is done by editing /etc/resolv.conf and adding these entries:

    domain Lynchburg.net
    nameserver 216.207.176.3
    nameserver 216.207.176.9

    Then edit /etc/host.conf to contain:

    order hosts,bind
    multi on

    Notice that in the actual config files, these lines need to be all the way to the left.

    Tip: Running your own DNS server will give you even better performance with lower latency and local caching. In order to do this, read the DNS-HOWTO thoroughly.
  5. Your PPP daemon is now configured. To dial into the Internet, as root run the command 'pppd'. To disconnect, run 'pppd' again or simply do 'killall pppd'.
