Is it possible to install roo components: hflowd, p0f, walleye, etc
(except base OS) under a CentOS paravirtualized xen guest?? Which
packages do I need to install?
I think it's probably possible now, but I've never tried. I'd advise
caution as updating will be a pain and possibly lead to breakage as
the various repos conflict. I think you'd be cleaner installing the
cdrom into xen directly. I prefer to think of the honeywall as an
appliance device.
If you want to do it, look at
http://www.honeynet.org/tools/cdrom/roo/repo-1.3
You'll need to yum install any package in there that isn't on your
system.
The attached code will tell you what isn't on your system and what
version mismatches you have. Let us know how it goes.
