Mainly a systems security guy with some Perl knowledge.

I'm reading through SICP and K&R right now. I wish someone had shown me SICP earlier in my career. Just Chapter 1 has been blowing my mind.

What manner of testing would certify the difference between Cat-5e and a Cat-6-quality cable? Obviously not just the standard 'do the pairs light up correctly'.. so what would be necessary?

@sparks - That's why I asked the SF community. :) Hopefully, the community at-large can vote up the correct answer. A lot of the information on the web seems to be from companies who would profit from their answer being the correct one.

For an example what I mean, see deepsurplus.com/Network-Structured-Wiring/Plugs-Boots/… - It mentions wire offsets for Cat-6 specs?

comment What sysadmin things should every programmer know?
Just because no one mentioned it doesn't make it untrue. This is a subjective question, and thus is normally made CW because it does not have a 'right' answer.

comment When are VLAN access maps actually applied to packets?
So when is it correct to say a packet entered a VLAN? Upon entering an access port defined as a member of a particular VLAN and/or when a packet gets switched internally to a VLAN-defined access port? Both? Neither?

comment Network monitoring on a virtual web server
I'm a bit confused by the idea of a 'dedicated, virtual' server. Aren't those contradictory?

comment Is it useful for unix admin to use linux on his work computer?
"Most" doesn't equal "all" though; there are some applications you cannot run in a VM due to performance and licensing - Core Impact, and other vulnerability scanners, come to mind.

comment TCP Sessions and IP Changes
In Stevens': p. 226, paragraph 1 and 2 describe the ip-port pairing. I can't seem to find any reference to where the connection "should be dropped".. mainly because I can't find any instance where he mentions any of those things changing within an active connection. I find it rather interesting that, without keepalive timers, TCP is supposed to maintain an idle, open connection indefinitely (see chap. 23). I really need to go back and read this tome again.
