Hello -

A pretty open ended question with lots of embedded issues. I am not an expert but have been working as a UNIX/ Linux Admin for about 3 yrs.

Pretty good place to start (IMHO) are some UNIX sys admin books. A few authors off the top of my head: Tom Limonicelli (sp?); Evi Nemeth, et al; Aeleen Frisch. I am sure I am forgetting some. These books (ie the O'Reilly Essential Unix System Administration by Frisch) are really useful as general, broad references. They lead to deeper topics and other books. The books I've read by Tom Limonicelli have been invaluable for learning how to become more professional and systematizing your day to day practice. I find myself going back to these authors over and over.

As for CompSci programs - it is always a good idea to go to school if you have time+money but I am not sure that it is completely necessary to become a sysadmin. I have take graduate cert courses at a local engineering school (Stevens Tech) and some were really valuable. I even took a course in Unix Systems Administration but I am not sure it is still offered...

One general theme of sysadmin books is the idea that the field is more akin to a guild than an academic discipline. As with a craft or a trade, your learning is typically an alternation of practice and study. And learning from master craftspeople. I have found my local LUG (NYLUG) pretty valuable and try to keep abreast of discussions on groups like SAGE and LOPSA.

You are already on this list which is a fine one. There are more to search out.

See yourself as a member of a guild, I really thing this is a "useful fiction" as System Administration is one of those fields that is hard to define.

Hope this helps abit with the first part of the question...

As for Linux/ Unix distribution choice. Just keep trying them. You will probably gravitate towards a particular way of package management/ software installation and that will be your distribution.

I happen to be on Ubuntu for work and it is fine. I like Debian so Ubuntu is a comfortable fit.

I worked on NetBSD for a while and found pkgsrc really interesting. Likewise for OpenBSD which I have on a laptop at home.

I havent met too many distributions that I didnt find worth checking out, though I don't tend to choose RedHat or SUSE.

best of luck

Michael

aspect::advice::after

Aspect::Advice::After(3pm)				User Contributed Perl Documentation				Aspect::Advice::After(3pm)

NAME

       Aspect::Advice::After - Execute code after a function is called

SYNOPSIS

	 use Aspect;

	 after {
	     # Trace all returning calls to your module
	     print STDERR "Called my function " . $_->sub_name . "
";

	     # Suppress exceptions AND alter the results to foo()
	     if ( $_->short_name eq 'foo' ) {
		 if ( $_->exception ) {
		     $_->return_value(1);
		 } else {
		     $_->return_value( $_->return_value + 1 );
		 }
	     }

	 } call qr/^ MyModule::w+ $/

DESCRIPTION

       The "after" advice type is used to execute code after a function is called, regardless of whether or not the function returned normally or
       threw an exception.

       The "after" advice type should be used when you need to potentially make multiple different changes to the returned value or the thrown
       exception.

       If you only care about normally returned values you should use "returning" in the pointcut to exclude join points occuring due to
       exceptions.

       If you only care about handling exceptions you should use "throwing" in the pointcut to exclude join points occuring due to normal return.
