Chapter 1 questions regarding hardware
I would like to know the best type of hardware to use for optimal performance. I am interested in such areas as:
Single vs Multi-Processor
There is no special advantage or disadvantage with respect to Linux and
computers with different numbers of processors. If you use a
multi-processor computer, be sure to use the Linux kernel related to SMP
(shared memory multiprocessor).
If you're using Red Hat Linux or Red Hat Enterprise Linux, you can
review hardware at hardware.redhat.com. Be aware that you may be able to
use more than just the certified hardware tested by Red Hat; for more
inforation, see the Hardware-HOWTO at www.tldp.org/HOWTO/Hardware-HOWTO.
How much RAM
First, there are minimums related to Red Hat and Red Hat Enterprise
Linux. Generally 128MB and 256MB respectively are the minimums required
for Red Hat Linux 9 and Red Hat Enterprise Linux 3 as a workstation.
What you need as a server really depends on the number of users, and
whether you're using this server for other purposes, such as a Web
server, FTP server, etc.
Disk drive and RAID Controller options
Please refer to the hardware information described earlier.
On the point 1 where it says "Insert the first CD into the drive...',
according to RH Linux 9, samba-swat package is on the third CD, not the first.
Page 133 - Quotas
"Once the file is configured, it's easy to enable quotas. Just run the following command:
I'm trying this on Fedora Core 2 - 2.6.9-1.6_FC2
When I enter the command above, it states:
"Bad number of arguments.
quotaon [-guvp] [-F quotaformat] [-x state] -a
quotaon [-guvp] [-F quotaformat] [-x state] filesys ...
What arguments should be used?
I missed the /home parameter here. In other words, in the context of this chapter, the command should be
# /sbin/quotaon /home
This activates quotas before the next reboot.
To continue, when I wrote "The next time you reboot Linux, it uses the
settings you changed to find the quota files you created during this
process," the boot process executes /etc/rc.sysinit, which runs the
quotaon command on all applicable filesystems in /etc/fstab, i.e., those
with usrquota and or grpquota defined.
