[sf-lug] UNIX admin help!

Why, sure, to the extent I can.

   Don't forget that you, Ola, have a user account on the sf-lug.com
host. Any SF-LUG members can have shell accounts on the sf-lug.com
box. You'll need a ssh client on your machine to access sf-lug.com
   Email me privately, Ola, if you forgot things. Log in and try out
commands per the following:

   Take a look at the sf-lug web page; click the Red Hat certification
study group sample pages. or click http://www.sf-lug.com/index1.html

   The vi editor is important, so click the How2vi.html link.
or click http://www.sf-lug.com/How2vi.html  Practice a bit!

   Using the bash shell is the modern default on most Unix systems
or at least an alternative (sometimes POSIX compliance requires
the real Bourne shell /bin/sh ). Click the bash shell tutorial link or
click http://www.sf-lug.com/BASHshscrOutline.html
   Please, please complain about anything in the bash shell tutorial
that is unclear or insufficient or otherwise unsatisfactory, please,
   In my view the chief deficiency in the tutorial is that some
important info is missing and the chief merit is that this includes
most important info in a single place--I have yet to find another tutorial
that brings together this number of essential concepts in a single,
integrated spot.
   Pay particular attention to the commands in the /bin directory.
Complain, please, please, and demand that I come up with a
grouping of those commands--those that have to do with filesystems,
those that are shell programs, those that have to do with networking,

   What kind of Unix? The tutorial is pretty general, although with
a Linux flavor. Solaris, HP-UX, AIX are all in play: generally a shop
is one of the three with some hosts running Linux and with Windows
looming outside on the users' desks.

   What kind of machine room and NOC environment? these days
sysadms are expected to know how to use big-bucks programs
such as NetBackup and one or more monitoring programs and
how to use console servers and so on.
   There's the DB angle: they're everywhere, including in unexpected
places (check your pants!). Oracle is a world of its own. There are
little MySQL or PostgresSQL databases lurking under a variety of
   There's the daemon angle: what's a server, which are used in
your joint, where are their configuration files, how to start, stop,
get status properly...?
   How are your LDAP skills?
   There's the policy angle, including allowed logins, use of sudo,
host-application rules, external standards compliance....

   On the SF-LUG.com RHCE/T study group page there's a Study
Path section with pathetically few sub-pages, each with pathetically
little further information. Please, please complain and demand that
they are improved.

and many, many thanks for asking.
