There is a new initscript version.
The mirror servers are not updated yet, and the http access on redhat's server is almost not possible, since you'll be disconnected after having downloaded 32K.
Use the ftp access instead:
ftp://download.fedora.redhat.com/pub/fedora/linux/core/updates/2/i386/
Download both the new initscript rpm and the ppp rpm.
install those files with
rpm -U initscripts-7.55.1-1.i386.rpm ppp-2.4.2-3.FC2.1.i386-rpm
(maybe the filenames are a little different !?)
