Linux - How to install an entire Desktops in the Command Line

Here's a quick list of commands to install several Linux Desktops, in the Command Line. Note: this was written, at the time of Fedora 18's Release. But, I used the KDE install command today in Fedora 20 and it worked as is should. I think most or all of the commands, should not have changed, since then...

Don

GNOME

sudo yum groupinstall "GNOME Desktop Environment"

KDE

sudo yum groupinstall "KDE Software Compilation"

XFCE

sudo yum groupinstall "Xfce"

LXDE

sudo yum groupinstall "LXDE"

Seeing all group availables :

sudo yum group list

if you are not willing to use the old desktop use:

yum groupremove [group]

Safety Alerts for Human Medical Products > GenStrip Blood Glucose Test Strips by Shasta Technologies: FDA Safety Communication - May Report False Results

GenStrip Blood Glucose Test Strips by Shasta Technologies: FDA Safety Communication - May Report False Results

[Posted 04/29/2014]

AUDIENCE: Pharmacy, Risk Manager, Patient

ISSUE: The FDA is advising people with diabetes and health care professionals to stop using GenStrip Blood Glucose Test Strips because the strips may report incorrect blood glucose levels.

During a recent inspection of Shasta Technologies LLC, the FDA found extensive violations of federal regulations intended to assure the quality of products in the manufacturing of GenStrip Test Strips. FDA found that Shasta Technologies did not have in place many of the requirements of a quality system. Without assurance of an adequate quality system, the FDA believes that the strips could report incorrect blood glucose levels.

BACKGROUND: GenStrip Blood Glucose Test Strips, sold by Shasta Technologies LLC, are "third-party" blood glucose monitoring test strips. Shasta’s GenStrips are advertised for use with the LifeScan OneTouch family of glucose meters (e.g. Ultra, Ultra 2 and Ultra Mini).

RECOMMENDATION: Discontinue use of GenStrip Blood Glucose Test Strips. FDA recommends the use of alternative glucose test strips that are designed for use with the LifeScan OneTouch family of glucose meters.

How to set up a primary DNS server using CentOS

Posted on April 10, 2014 by Sarmed Rahman 3 Comments

Any operational domain has at least two DNS servers, one being called a primary name server (ns1), and the other a secondary name server (ns2). These servers are typically operated for DNS failover: If one server goes down, the other server becomes an active DNS server. More sophisticated failover mechanisms involving load balancers, firewalls and clusters are also possible.

All DNS entries for a particular domain are added in the primary name server. The secondary server will simply sync all the information from the primary name server based on counter type parameter set on the primary server.

This tutorial will describe how to create a primary DNS server running on CentOS. Please note that the DNS server presented in this tutorial will be public DNS, meaning that the server will respond to queries from any IP address. Limiting access to the server will be discussed in future tutorials.

Before we start, I would like to mention that DNS can be set up with or without chroot jail environment. The chroot jail environment confines the DNS server to a certain directory in the system, as opposed to allow the server system-wide access. That way, any vulnerability of the DNS server would not compromise the entire system. Chrooting a DNS server is also useful for a test deployment.

Objective

We will be setting up a DNS server in a test environment for the domain example.tst, which is a hypothetical (non-existing) domain. That way, we will not accidentally interfere with any other live domain.

In this domain, there are the following three servers.

Server	IP address	Hosted services	FQDN
Server A	172.16.1.1	Mail	mail.example.tst
Server B	172.16.1.2	Web, FTP	www.example.tst ftp.example.tst
Server C	172.16.1.3	Primary DNS server	ns1.example.tst

We will be setting up a primary DNS server, and add necessary domain and DNS records as shown in the table.

How to set up a secondary DNS server in CentOS

Posted on April 15, 2014 by Sarmed Rahman 2 Comments

In the previous tutorial, we created a primary DNS server (ns1) for a test domain example.tst. In this tutorial, we will create a secondary DNS server (ns2) for the same domain by using bind package on CentOS.

When it comes to setting up a secondary DNS server, the following factors should be kept in mind.

You do NOT need to manually create forward and reverse zone files in the secondary DNS server. The zone files will be periodically synced from the primary DNS server automatically.
Whenever any zone file is modified in the primary DNS server, the parameter 'serial' should be updated. The secondary DNS server will initiate synchronization (zone transfer) only if serial at the primary server has been changed.

We assume that the IP address of the secondary DNS server to be set up is 172.16.1.4. Let us start installing.
