It's my opinion that the Level III exams are intended to provide a certification
avenue for high level Linux folk who want to specialize. For this reason the
rubber meets the road in *THIS* level for the enterprise level services you've
mentioned above. We are going to need to pound NFS/NIS, Samba, DNS, IMAP, DHCP,
SMTP, and I suggest that we add OpenLDAP into the mix. It's being included with
many of the distro's now and Novell is kicking their contributions out under OSS
licenses of some type. It may seem like an altogether specialized area but I
think that we should at least examine the issue to see where it leads.
What am I leaving out???

I think we will have to include some kernel performance and security issues in
Level II. Development can wait (if we ever get to it at all).

Agreed.

I agree with this... I particularly like the ipchains inclusion... we need to
remember that ipchains is a great tool for controlling and securing single
servers as well as a firewall tool for entire networks.
I am going to bring it up now... what do folks think about testing xinetd? It is
much more configurable than wrappers and provides a higher level of security
when properly implemented!

I'm going to presume that we're interested in the uses of this hardware and how
to enable it's interaction with the OS. Otherwise we would/will be getting into
compatibility and driver issues across distro lines... a very ugly situation!
Perhaps we may want to get into some RAID here... we *are* talking about
advanced hardware devices here! We should also discuss software RAID as the
raid1 implementation in the 0.90 raidtools is very nice and quite stable!
