Slightly OT: which hardware for CentOS file server (Samba, 2 To storage, 50 users)?
Hi,
The language lab from the local university has contacted me. They'd like
to have a low-cost file server for storing all their language video
files. They have a mix of Windows, Mac OS X and even Linux clients,
roughly 50 machines. The files are quite big, and they calculated a
total amount of 2 To of storage.
I'm not very proficient with hardware, meaning either I'm dealing

What files to edit when changing the sdX of hard drives?
Hi
I have read instructions for udev, I also found many example on how to do this.
I want to lock in the SDA/SDB/SDC for my drives and I came up with a rule like this
KERNEL=="sd?", SUBSYSTEM=="block", ENV{ID_SERIAL}=="ST500DM002-1BC142_W2A56H8A", NAME="sda", RUN+="/usr/bin/logger ID_SERIAL=$ENV{ID_SERIAL} set to /dev/sda ",

Simple solution for small network in a school ?
Hi,
I have to install a small network in a school in a nearby village. The
network will be Linux-only, one server and fifteen desktops. Here's the
idea.
1) Authentication should be managed centrally on the server.
2) User home directories should also be on the server.
3) Users should all have disk quotas, something like 1 GB per user.
4) Some shared directories should be read/write for

Using cdrecord on CentOS
Hi,
I'd like to use cdrecord on the command line. I'm currently reading the
relevant chapter in Carla Schroder's "Linux Cookbook". Unfortunately,
some of the tricks and hints included in the book don't seem to work the
same way on a standard CentOS 5 install.
1) Am I supposed to be root to use cdrecord and burn an .iso file?
2) How do I specify a device?

Router for SOHO network - hardware considerations
Hi,
Last week I finished installing a small network in a private school :
one server (an old IBM X225), seventeen desktops (Fujitsu Siemens PIV
2.4 GHZ, 512 MB RAM, 40 GB HD), all running CentOS 5.5.
One extra machine is acting as a router, in that it is installed between
the DSL modem and the network, with two Ethernet cards, and it's taking
care of DHCP, DNS, NTP and also acts like a

No network on cloned CentOS 7 installation
Hi,
I have a few identical Dell Optiplex 7010 machines that I want to use
for our school's computer room. I tried to clone these installations
(like I did before on CentOS 5 and various versions of Slackware), but
this time I ran into a problem.
Here's what I did.
1. Install one computer and zero unused hard disk sectors with dd.
2. Send the image to a local FTP server using G4L

Spamassassin + Postfix : delete spam mail on the server ?
Hi,
My mail server is running on CentOS 7 with Postfix, Dovecot and
Spamassassin. I get quite a lot of spam on a few accounts, and
Spamassassin does its job fine. Spam mail is identified correctly, and
it looks like there are no false positives, e. g. valid mail is never
identified as spam.
When a message is flagged as spam, the subject line is rewritten to
begin with [SPAM]. Then, a filter in

"Linux aux petits oignons" - Book about Linux, based on CentOS 5.x
Hi,
I'm currently busy finishing "Linux aux petits oignons", a practical
introduction to Linux, aimed primarily at the frustrated Windows user.
This is the first of two volumes, it's written in french, and all
examples in the book are based on CentOS. (Note: looks like I'll have to
update some screenshots to 5.3 :oD)
Usually the first question that arises is: why not

apache redirection
Hello everyone,
Part of our website has secured access with an SSL certificate. The
problem we are running into is that the certificate is for
www.domainname.com, so when they go to domainname.com (without the
www. in front), the users are getting a "This connection is untrusted"
warning, because the url doesn't match the certificate.

OT: Linux WYSIWYG HTML Editors
I have KomPozer installed, but after using M$ FrontPage for years,
KomPozer looks like it is going to have a learning curve and I want to
get away from FrontPage and Windows. I know Mark (MHR) uses
SeaMonkey. Wondering if there is anything else I can use on Linux that
is easier on a FrontPage user. I found this article:

Yeah - I strongly believe in labels, given the fact that *no* one can
remember a UUID....

cameras and CentOS
Hi
I want to put up a few cameras connected to a CentOS box.
I currently have a box with one camera and that works (USB),
I can take a pic (the script does that) and see that on a webpage.
However, I want to have a couple of cameras a little further
away (more than 5 meters).
USB has a limit, I have tried that camera with a longer cable
and it does not work ... so I need to route that in a

Fiddling with software RAID1 : continue working with one of two disks failing?
Hi,
I'm currently experimenting with software RAID1 on a spare PC with two
40 GB hard disks. Normally, on a desktop PC with only one hard disk, I
have a very simple partitioning scheme like this :
/dev/hda1 80 MB /boot ext2
/dev/hda2 1 GB swap
/dev/hda3 39 GB / ext3
Here's what I'd like to do. Partition a second hard disk (say, /dev/hdb)

1) Power off 2) Automatic updates with GNOME
Hi,
1) When I'm doing a server install as well as a desktop install, I
always start from a minimal install, then add components as needed. Now
I noticed that on a minimal system (no X11, no GNOME), when doing either
'halt' or 'shutdown -h now', the machine halts... but doesn't switch off
the power. The user has to do it manually. (I vaguely remember that on

SquidAnalyzer: minor trouble building RPM
Hi,
I'm using the SquidAnalyzer network analysis tool in combination with
Squid. Up until now, I've been running Slackware Linux on my servers. I
built a custom package that installs SquidAnalyzer to
/var/www/vhosts/squidreport/html. Then I setup an Apache virtual host
for SquidAnalyzer's pages.
Since I'm migrating my servers from Slackware to CentOS, I'd like to

Package group "X Window System" has disappeared
Hi,
Until last week, I could install a CentOS 7 based desktop using the
following approach:
1. Install minimal system.
2. yum groupinstall "X Window System"
3. yum install gdm gnome-classic-session gnome-terminal liberation-fonts
4. Install applications as needed.
This morning, the package group "X Window System" seems to have
disappeared. This is embarrassing.
