[PLUG] Another favorite book, and it's free!

[Michael Dexter]

Hey,

For those who caught my run through some of my favorite tech books at 
last night's meeting... I completely forgot about "The Linux Command 
Line" which is available both from No Starch Press and as a free download:


http://linuxcommand.org/tlcl.php

It is great about starting at zero on the command line and as I recall, 
generating HTML with shell scripts.


Enjoy!

Re: [PLUG] Dell Optiplex 360 BIOS update

IIRC, many DELL BIOS had an option that disabled USB boot hidden under "on
board devices - usb" or some such.

Also, seem to recall that you could also tell the BIOS the internal
floppy is USB, then it will boot from a USB stick that is emulating a
DOS floppy.


Ed,

  The system shows both internal floppy/usb and external usb. Both are
marked 'not installed' and I've not found a place to change that the
external usb to 'installed.'

  If you'll have time this weekend I can bring the box over to your house
since you've more experience with these hardware issues than have I. Perhaps
together we can get the BIOS upgraded and make the external usb the first or
second boot device choice.

Free IPA would be excellent topic for talk...

I for one would love to hear practical experience with it.

Re: [PLUG] Mail log reporting differences

On Thu, 3 May 2018, wes wrote:


The first thing that sticks out to me, is that the elements being reported
are different. Logwatch reports "Accepted" and "Rejected" emails, while
pflogsumm repots "Received" and "Delivered" emails. These could very well
be 4 different metrics.


Wes,

  I assumed the terms were equivalent between the two scripts and your
questioning that assumption makes really good sense.

  As I wrote this issue is just a matter of curiosity than anything else and
not worth anyone's time digging further.

Thanks for your thoughts,
