Laptop Locating resource

farslayer — Thu, 09 Apr 2009 12:40:51 GMT

The Linux Laptop Sites are a great resource for finding out what works and what doesn't on a particular model of laptop.

Look at what laptops manufacturers are selling with Linux.. If a manufacturer is selling or certifying a particular model, odds are it will work well with whatever distribution of Linux you wish to install on it.

UDEV Rules

farslayer — Fri, 27 Mar 2009 13:25:39 GMT

udev Rules for the Hard drives..

Use udevinfo to get unique attributes about the devices you are going to write a rule for.

udevinfo -a -p /sys/block/sda | grep -i model
Gives the following output: SYSFS{model}="LD 0 RAID1 139G"

udevinfo -a -p /sys/block/sda | grep -i size
Gives the following output: SYSFS{size}="286515200"

udevinfo -a -p /sys/block/sdb | grep -i model
Gives the following output: SYSFS{model}="PERC 5/E Adapter"

udevinfo -a -p /sys/block/sdb | grep -i size
Gives the following output: SYSFS{size}="10732699648"

2. Now that we have unique information about each device, we can write a udev rule and rename each device.
cd /etc/udev/rules.d
vi 51-perc.rules

Place the following into the file:
SYSFS{size}="10732699648", SYSFS{model}="PERC 5/E Adapter", NAME="sdb"
SYSFS{size}="286515200", SYSFS{model}="LD 0 RAID1 139G", NAME="sda"

Issue a "udevstart"

Setting the Linux Hostname

farslayer — Mon, 02 Mar 2009 14:49:01 GMT

Originally Copied from http://www.cpqlinux.com/hostname.html
The original site has been down the last several times I have checked, so I am reposting the info here in my blog..

Setting the Linux Host Name

Start at the top and complete ALL steps..

-------------------------------------------------------------------------------
Checking your Linux host name
First, see if your host name is set correclty using the following commands:

Code:

uname -n
hostname -a
hostname -s
hostname -d
hostname -f
hostname

If the above commands return correctly with no errors then all may be well; however, you may want to read on to verify that all settings are correct.

-------------------------------------------------------------------------------
Configuring /etc/hosts
If your IP address is assigned to you by a DHCP server, then /etc/hosts is configured as follows:

Code:

127.0.0.1	mybox.mydomain.com	localhost.localdomain localhost mybox

If you have a static IP address, then /etc/hosts is configured as follows:

Code:

127.0.0.1	localhost.localdomain localhost
192.168.0.10	mybox.mydomain.com	mybox

--------------------------------------------------------------------------------
Setting the Host Name using "hostname"
After updating the /etc/hosts file correctly, the "hostname" command should be run as follows to set your hostname:

Code:

hostname mybox.mydomain.com

---------------------------------------------------------------------------------
Checking /etc/HOSTNAME (if present)

You may or may not have the file /etc/HOSTNAME:

Code:

mybox.mydomain.com

--------------------------------------------------------------------------------
Checking /etc/sysconfig/network

If you have a static IP address, then /etc/sysconfig/network is configured as follows:

Code:

NETWORKING=yes
HOSTNAME="mybox.mydomain.com"
...

If your IP address is assigned to you by a DHCP server, and you wish to update the local DNS server through Dynamic DNS, then /etc/sysconfig/network is configured as follows:

Code:

NETWORKING=yes
HOSTNAME="mybox.mydomain.com"
DHCP_HOSTNAME="mybox.mydomain.com"
...

-------------------------------------------------------------------------------

Checking /proc/sys/kernel/hostname

This is checked with the following command:

Code:

cat /proc/sys/kernel/hostname

If you need to set this file, you can either reboot or set it now with the following command:

Code:

echo mybox.mydomain.com > /proc/sys/kernel/hostname

-------------------------------------------------------------------------------
Dynamic DNS - Updating the local DNS server with your host name and DHCP IP

If you receive your IP address from a DHCP server, you may update the local DNS server by adding the following line to /etc/sysconfig/network for Red Hat:

Code:

DHCP_HOSTNAME="mybox.mydomain.com"

or if running Debian, edit /etc/network/interfaces as follows (adding the hostname line):

Code:

iface eth0 inet dhcp
    hostname mybox.mydomain.com

For more info in Debian, see "man interfaces" and scroll down to "The dhcp Method".

---------------------------------------------------------------------------------
WINS - Updating the local WINS server with your host name and IP

If you wish to update the local WINS server, then use SAMBA, and configure it to point to the local WINS server.

This site was started after the significant positive response to Free and Open Source software by educators at the National Educational Computing Conference (NECC) held in July, 2006

http://www.gnu.org/education/
Free Software can be a valuable resource in education. Not only can it be technically or pedagogically superior to proprietary alternatives, but it can also promote the values of the GNU project in the schools:
* Freedom
* Cooperation

Today, many students and schools don't even know about Free Software or the great advantages it brings. At the same time, software knowledgeability is required for more and more tasks, and Free Software has a distinct advantage in this field.

Fix is to delete the ~/.gconf/system/networking directory.

This resets the networking config files forcing the NetworkManager to recreate them.
