Laptop requirements for "Demystifying Sendmail"
Greetings—
For those of you who will be attending my "Demystifying Sendmail"
class at the Sys Admin Technical Conference in Baltimore, I wanted to
give you a "heads up" about how you'll be using your laptop during the
hands-on lab exercises in the course.
The lab exercises are based around configuring a series of VMWare
instances to create a small network of email servers. So the most
important criteria for selecting your laptop is that it must at least
be capable of running VMWare. This probably means your laptop should
be running Windows or Linux. If you're running Linux you should
download a copy of VMWare (either Server or Player, or even the
commercial Workstation product) BEFORE YOU COME TO THE CONFERENCE and
make sure that it works OK with the version of the Linux kernel that
you have installed. Please refer to the VMWare documentation for
information about installing VMWare products under Linux.
What about folks with Mac laptops? Well VMWare does provide a free
beta version of their "Fusion" product for x86 Mac machines (if you
have an older PowerPC based laptop, I'm afaid it's not going to work
for this class). Frankly, I don't have a Mac and haven't tested my
VMWare images under Fusion — it's supposed to work, but... If you're
interested in trying to use an x86 Mac for the class, please contact
me before the conference and I'll shoot you a copy of the VMWare image
so that you can test it out before you get to class.
The other major issue is disk space. During the labs, we're going to
have as many as four different VMWare instances running at the same
time. The virtual disk for each image consumes about 1.5GB of disk
space, plus you'll need some additional space to install VMWare, create
new configuration files, etc. Figure that whatever laptop you plan
on using should have about 7GB of free disk space.
Memory shouldn't be as much of an issue. The VMWare instances we'll
be using are configured to only use 64MB of RAM per instance. So if
your laptop has at least 512MB of RAM, you should be OK (though more
is better). Network access is also not an issue because the VMWare
instances are configured to use virtual "host only" networking, which
doesn't require a physical network connection. You will need a CD-ROM
drive on your laptop because I'll be distributing the base VMWare
image to the class on a CD-ROM (which you will be taking home with you
when the conference is over).
If you have any other laptop-related questions, feel free to contact
me. I look forward to meeting you all in Baltimore!
