Very Computer

First some backgound.... RedHat 6.0, kernel 2.2.5-15, USR 33.6 (not a winmodem)

I've edited ppp-on[off][-dialer] scripts to work flawlessly, however, If I try
to bring PPP up by running 'ifup ppp0', I get these errors:

SIOCSIFNETMASK: Cannot assign requested address
SIOCSIFBRDADDR: Cannot assign requested address
SIOCADDRT: Network is unreachable

ifcfg-ppp0 look like this:

DEVICE="ppp0"
ONBOOT="no"
USERCTL="no"
MODEMPORT="/dev/modem"
LINESPEED="115200"
PERSIST="yes"
DEFABORT="yes"
DEBUG="yes"
INITSTRING="ATZ"
DEFROUTE="yes"
HARDFLOWCTL="yes"
ESCAPECHARS="no"
PPPOPTIONS=""
PAPNAME=""
REMIP="0.0.0.0"
NETMASK="0.0.0.0"
IPADDR="0.0.0.0"
MRU="1500"
MTU="1500"
DISCONNECTTIMEOUT="60"
RETRYTIMEOUT="5"
BOOTPROTO="none"

I am under the impression that an address of 0.0.0.0 means that the address is
dynamic, and will be assigned by the server. My username, passwd, and ISP's
telephone number are located in the file chat-ppp0, in the same directory.

My question then is, why am I getting MSG's complaining about dynamic
addresses? Am I using the wrong syntax? What do I have to do from here to get
the command ifup ppp0 to call and connect to my ISP? I think I'm pretty
close...I hope its something simple that I'm over-looking.

Thanks in advance for your gracious help,
