Come seeking RedHat RPMs? They're tailored to your
kernel version, so download the matching set of 
userland/module RPMs your system needs.

If you are unsure as to your kernel revision, just 
run `uname -r`, or just execute:

ncftpget ftp.xs4all.nl/binaries/RedHat-RPMs/`uname -r`/\*

Userland-only RPMs meant to be used atop the 2.6 native 
kernel IPsec, will be coming soon.
