I echo the other comments.  My most used admin tools are vi, netconf and
printtool.  But it probably depends on the system's use.  I might be
persuaded to someday try comanche again.

But the first thing I always do is the custom install where I examine each
package installed.  Ok, there are a few I may not really understand but the
idea is literally only to install the ones I need.  Or maybe I'll install
more for a test system but it can turn into a security nightmare (you decide
not to upgrade some vulnerable package but you forget to remove it... maybe
you find yourself cracked).  If you do need to temporarily remove a service,
one way is to go into /etc/rc.d/rc3.d and change the service's capital 's'
to a small 's' (NNS<command> to NNs<command>).

There are security models where there are powerful non-root users but I
think they would be a mistake in the standard Linux model... so just be a
regular user and 'su' to root when you need that.  Even better, use "su -c
'command'" to execute that command.  I would urge you not to logon or check
POP mail across any insecure network without encryption.  And I would urge
you to consider all networks insecure.

Definitely go get OpenSSH.  It's easy to install on a 6.1 or 6.2 machine and
works right away; there's little configuration needed (for me anyway).

I have a set of customizations I'll install if I'm going to use the system
much (vimrc, aliases, etc.).
