For network hands on, as you learn more and more about how networking works, try and make it more complex than you need to. Branch out and experiment.

Can you elaborate on that please? What type of network services are you running?
Hmm, the Network+ topics are really everything that I covered in my grad school class. Maybe I'll jump right to the CCNA. I just emailed my professor and asked him what he thought so I'll let you know.
For undergrad, I went to Union College in Schenectady, NY. It's a small liberal arts school, only about 2800 students total. Here's the CS curriculum to give you an idea: http://cs.union.edu/CSDEPT/Curriculum/C ... uirements/
Most of it was centered around coding, both in theory and in practice. The Cisco and Red Hat certs wouldn't have done me any good with that particular degree, but every school is different.
I've use VirtualBox to run a virtual machine (vm) using Ubuntu Hardy Heron (8.04.2 LTS) Server edition running DHCP, LDAP, and NTP services. I'm working on a private mail server and caching DNS server, but I'm trying to use BIND and Postfix, which aren't the easiest things to configure. It's easier if I used dnsmasq and qmail, respectively, but I'll learn more using the more feature-rich apps. Running it all from a vm can be impractical because my host computer (which is also my gaming rig) can't get an IP, can't get it's clock set, or access LDAP until I start the vm. If I were wanting to play around with PXE booting or something, I'd have to get a dedicated machine. My old PIII rig I was using as a server got sold as I'm planning a cross-country move this summer. When I get to Florida, I'll hopefully get a nice little machine to run more stuff.
I wasn't recommending the Red Hat certs for you. Unless you aspire to work specifically with Red Hat systems, it would be a waste. I was simply talking for me. Security Specialists differ from SysAdmins. What you're going for is a specialty. You do security. Mail servers, web servers, databases.... those are others people jobs. You maintain the firewalls and other security points for a large network. Typically, a SysAdmin is a generalist. Jack of all trades, master of none. I just mentioned the Red Hat certs because those are my goals. RHCE and CCNA before Fall '10. There are definitely some great Cisco certs for a security guy though, and the CCNA is a wonderful starting point.
I've flipped through a few CCNA books myself, including a couple from Cisco Press. I have to say though, my favorite title, and the one I'm reading currently is under Sybex Publishing by author Todd Lammle. It's stuffed to the rafters with detailed info, but it's not dry and boring like other ones. No, I don't work with Sybex or the author. It's the best networking book I've read, hands down, and I recommend it to everyone who wants to get into networking, or who wants to have a detailed knowledge of how a large network operates.

Good to know a professor's thoughts on the Net+. I'm not moving until I've got a cert to *help* in getting me a decent job, and the Net+ was my backup in case I wasn't ready for the CCNA in time. Looks like it's CCNA or bust for me.
