comment Regular user using ports below 1024
This gives considerably more privilege to the process than simply allowing the binding of low ports; this is equivalent to handing the user in question root, and you might as well use something a little more widely adopted in a case where that isn't a problem, such as sudo.

comment Server clock running too slow
What Chopper3 said; if it turns out that you're on a virtual machine, VMware has a few recommendations for running Linux guests under their product: kb.vmware.com/kb/1006427 (Note that, for RHEL4/CentOS4, the recommended kernel options are "clock=pmtmr divider=10".) However, you should definitely be running ntpd, if you aren't already.

comment Getting a shell on a shell-less account?
A very quick suggestion: you might want to be specific about the environment variables you're finding aren't set to your liking.

comment How does an UltraSPARC IV+ compare to Intel
Agreed: without knowing the target workload, comparisons are meaningless. Heavily concurrent or single-threaded workloads? Processing or I/O bound? You need to understand what you intend to do with a given architecture before building it.

comment What is the canonical way to store iptables rules
I was referring to the addition to /etc/network/interfaces; my apologies, I should have been more clear. Fedora and RHEL have an initscript (cleverly named "iptables" ;) that, if enabled, essentially does an iptables-restore of /etc/sysconfig/iptables.

I'll point out that this is Ubuntu-specific. For Red Hat and Fedora variants, you'll be looking at /etc/sysconfig/iptables instead.

comment How do you recognize a good system administrator?
Agreed with Manni: I might rephrase that as "at least minimal coding abilities". Development skills are invaluable in a system administrator.

comment How do you recognize a good system administrator?
I can find very little fault with any of this, except for the the second last point: any sysadmin who would be willing to share documentation from a previous job is someone who may very well share documentation about your environment in the future. By necessity, a business places a great deal of trust in their systems administration staff, and while I agree it's a good question, I think it's good for a completely different reason.

comment How can I determine what hosting provider hosts a site?
Absolutely, but again, you should definitely take it with a large grain of salt: just because the website is hosted with a particular provider, doesn't mean the DNS is hosted by them as well. I'd typically defer to the ARIN lookup data if you're primarily interested in the (web/application) hosting provider, as well as the traceroute information.
