Using books from the LDP? Yes, that's a very good learning source,
but you've also got to be _using_ the O/S. Nothing beats experience.

You seem to have 'split thread' and replying to two people - that is
bad form and confusing.

If you look at the References: header, you'll discover the O/P was
posting from google - and one of the items that score file kills is
articles with a Message-ID containing the string 'googlegroups.com'.
As I try to scan eighty newsgroups every day, I don't have time to
waste clicking 'delete' on spams posted from there. Harsh, but a fact
of life. However, my response was aimed at both of you specifically,
and all readers. Usenet isn't email.

LDP is a good source - I typically read the O'Reilly books cover to
cover as well.

My wife forbids me to enter a book store - I spend to much money there.
None the less there are a dozen O'Reilly books between the monitors in
front of me now, and more in the book shelf behind me.

I don't feel learning things is a waste of time/money, but far to often
the expectations of the investment is what is a waste. For me it is
also a business expense (I am a consultant) so it would still be worth
it. :)

1. Novell was teaching (and testing) in their "Network Technologies"
course that thick Ethernet used RG-8/U or RG-11/U. Two lies for the
price of one - RG-11 is 75 Ohm, not 50 Ohm as specified by DIX, and
both cables use a vinyl jacket material specifically prohibited by
the DIX spec (and virtually all fire inspectors / insurance companies).

2. Microsoft was teaching Class-ful networking (Class A, B, C) as the
ONLY size of networks, six YEARS after RFC1517 introduced CIDR

1517 Applicability Statement for the Implementation of Classless
Inter-Domain Routing (CIDR). Internet Engineering Steering Group, R.
Hinden. September 1993. (Format: TXT=7357 bytes) (Status: HISTORIC)

Now I rather doubt many people are using thicknet any more, but I DO
expect people to know why plenum rated cable exists. As for CIDR
networking, the net mask here is a /22 so it would be desirable to know
what it looks like if you're going to work here.

[MCSE for a hell-desk]

Most helpdesks I have seen want that now... that is why they are all
going to hell... or to India.

Ya gotta point there. Luckily, we're still putting real live humans on
the desk, and we expect them to solve the problem on the spot.

I am over qualified for helpdesk, and probably would not be able to
get a job on one (I certainly wouldn't stay on one!)

We only have one person in the barrel (it rotates through the department
so you only are on the phone one day every other week), but the other
staff are on call to handle things not fixable over the net. I'm senior
enough to only get caught when things are really getting out of hand.

Read what he said. Unless you are sure that the job requires the GUI
admin experience, learn the commands that actually do the job. Other
distributions don't use the Red Hat specific tools, nor do the various
versions of UNIX. But if you know how to get information from (for
example) 'ps aux' or 'netstat -antu' you'll be a lot more desirable
and will get a better job. (The "Advanced Bash Scripting" guide from
the LDP is _very_ useful.)

ps aux? Boy, you are 'Old guy' ;)

None of our servers run X (heck, most don't even have video cards, being
admin'd over the wire, or through a remote serial console), so the GUI
stuff is generally useless. Despite the wishes of marketing departments
at the various O/S providers, we don't use a single distribution of
Linux - heck, we've also got Solaris and FreeBSD running here. A single
GUI knowledge is useless. Not only that, most of the systems lack a
removable media drive (floppy, CD, DVD), so booting to rescue media isn't
generally an option. Now 'peachpit' in server room 2 isn't responding,
and there is the beginnings of the mob (complete with burning torches
and pitchforks) forming in the hallway. How soon can you get that system
running?

But yes, resourcefulness is the one qualification that most are missing
- they can not find information. That is usually the best thing to
test in interviews!

Some time ago, I was interviewing an applicant for student intern here
(we've an agreement with several local universities to provide a quarter
of "work experience" for certain disciplines), and the student mentioned
that she ran Linux (Mandrake or Red Hat - it was that long ago) at home.
"Oh boy", I thought - "another icon clicker". The position being
interviewed for was something like second or third assistant tape monkey
but we also have positions in the NOC. So I asked a couple of leading
questions that would expose this problem. To my surprise, she knew the
answers, including knowing to include the full path to commands like
/sbin/ifconfig. Two other supervisors asked no more that four or five
additional questions, and the student was hired as a NOC intern. At the
end of the quarter, she was also offered a job here, which she accepted.
