Excuse my ignorance, but what's wrong with nslookup and ifconfig?
They're a bit dated. Use dig instead of nslookup, and right from the ifconfig man page: NOTE This program is obsolete! For replacement check ip addr and ip link. For statistics use ip -s link.

Pedantry, but keep in mind that there isn't really "the" man page for this.
Ubuntu might want to deprecate ifconfig, but that doesn't mean everyone does.

I'd also recommend any sysadmin to start looking into an automation framework like Chef, Puppet, Ansible, or any other of the myriad options.
Automation is a fine thing except for some of this damn "enterprise software" that not only doesn't automate real well[1], but actually cannot be installed on VMWare[2] or even go to a hot swap machine[3]. Sysadmins always love government required software and stuff bought before we got there. 1) luckily backup seem to be reasonably automation friendly 2) "We do not support virtualization of any kind" 3) tied to hard…
I personally haven't tried building environments on VMWare as I run pretty much everything in AWS. However, this presentation looks promising.

Cannot stress this enough! There is a sea change happening and sysadmins run the risk of being swept away unless they learn about automation (puppet/chef) software and cloud infrastructure services (openstack/aws). My new years resolution is to release screencasts on these very subjects. I have already released one on Learning Puppet with Vagrant @ http://sysadmincasts.com/episodes/8-learning-puppet-with-vag... if anyone is interested.

Where does it say that? http://www.openbsd.org/cgi-bin/man.cgi?query=ifconfig Pedantry, but keep in mind that there isn't really "the" man page for this. Ubuntu might want to deprecate ifconfig, but that doesn't mean everyone does.

Edit: I'm also having a difficult time trying to figure out how to get up to speed with chef in the specific context of opsworks, since most of the chef-specific courseware I can find assumes I'm using a hosted chef server, and I'm not quite sure how that overlaps with the opsworks flavor. It's starting to feel like I'll be at this for another week before I can get even a simple stack running.
