Linux emulation

Hi All,

I am trying to get Checkpoint's Firewall-1 management module installed on
FreeBSD 4.5R under Redhat 6.2 emulation.  I am not a Linux user really at
all, and am having some amount of trouble extracting what I need from the
RPM provided.

Checkpoint released a Linux version of their firewall software which is
broken into modules.  The firewall module itself involves a kernel patch,
and I don't expect I will get that working (but I don't need it).  The
management module should not require a kernel patch - it is just a network
interface between the GUI (yet another module) and the firewall
module.  All three can run on the same machine or three seperate machines
(or any combination thereof ;).

The firewall module(s) I want to manage are on dedicated hardware running
an OS called IPSO, which turns out to be stripped down FreeBSD with some
enhancements.  Currently the management module is running on my NT
desktop, as is the GUI.  My desktop dual boots FreeBSD and I use rdesktop
to get to my outlook mail and M$ apps required for office integration, but
I have to boot the damn thing in NT to modify the firewall rules or to use
the logging mechanisms.

So you see why I am incented to make this run on FreeBSD.

So I have this RPM, and if I try to install it I get:

jeffwork% s rpm -i --ignoreos --root /compat/linux --dbpath /var/lib/rpm
error: failed dependencies:
        kernel is needed by CPfw1-41-vpn+des

Fair enough.  I then tried with the --nodeps option:

jeffwork% s rpm -i --ignoreos --root /compat/linux --dbpath /var/lib/rpm
--nodeps CPfw1-41-vpn+des.i386.rpm

Which completed without errors, but didn't actually do anything (it
finished in less than a second).

I thought that RPM's were actually gzipped tarballs or some such, but
cannot seem to do anything with it with gzip, uncompress, tar, or
cpio.  Anyone know what exactly the file format is?  Or maybe how I could
unpack it and manually take what I need just for the mgmt module?
