Computing Hourly or Annual Rate


Constant multiplier = 2080

1. How to compute for the Annual Salary given the hourly rate?
   Hourly rate = $45.00
   Annual = $45.00 x 2080
   Annual = $93,600.00 

2. How to compute for the Hourly Salary given the Annual Income?
   Annual = $93,600.00
   Annual = $93,600.00 / 2080
   Hourly rate = $45.00

Data Recovery Using FreeNAS
Posted by FrugalNYC at 6:00 AM | Labels: backup, freenas, system admin, tech support

I have written several posts about FreeNAS in the last several weeks. For such a small and compact OS, I have found this to be one of my favorite tools of late. I first wrote about 9 Great Things About FreeNAS and then I wrote 9 Reasons To Use FreeNAS At Work. I then wrote 11 FreeNAS Tips that I picked up after using it and reading about it for several weeks.

Today I would like to talk about how FreeNAS can be used as a data recovery tool. Below is my account of how I used the FreeNAS LiveCD to restore data from a Windows Laptop. I've done this on a HP/Compaq Windows XP Laptop and it worked very well.

Bootup and Install

* I Boot up with the LiveCD.
* Configure the IP address via DHCP
* I go to another machine for the WebGUI to do additional configuration.
* From the WebGUI, I login with the default admin/freenas account.
* Then I setup the Disks - steps are below.

Adding the Disk I want to Recover

* Disks - Management - Add Choose the Disk.
* In My case it was the acd4, the only other one being a RAM Disk or CDROM Drive (acd0)
* I give the description as HD (Hard Disk)
* I leave everything else default, but I do change the Preformatted File system to NTFS
* Save the changes

Mount the Disk

* Disks - Mount Point - Management - Add mount point
* I Choose the Disk I configured above
* I chosse partition 1, since I know the Laptop only has one primary partition.
* Filesystem: I choose NTFS
* Sharename: I call it Windows. You can call it anything you want.
* I leave everything else as the default.
* save the changes.

Get to the Files

* For the easiest access to files I setup the FTP service.
* I go to Services - FTP
* I click enable and then Save and Restart.
* From windows explorer (on the machine I did the WebAdmin work and where I want the data restored to) I go to the folder ftp://freenasIP
* I see the files from my windows install and grab whatever files I need to backup.

Shutdown the Laptop

* When Done copying, I just shutdown the system.
* System - Shutdown

Voila! Now you know how to use FreeNAS as a data recovery tool. There are other dedicated recovery tools, such as SystemRescueCD, but I find FreeNAS very easy to setup and it gives me the results I want faster. Do you use FreeNAS? What features do you like best? Share your thoughts and comments. You can get the current iso of FreeNAS here. Do you have other useful resources for FreeNAS?

Cool. It seems so obvious after hearing this, but I probably would have never thought of using my LiveCD for this!

Hi Brian,

It pays to get a little creative huh? Technically, just about all LiveCD distros of Linux/BSD can be used to do simple data recovery work. I just find FreeNAS to be one of the easiest to use in this regard. :) Thanks for visiting and reading FrugalTech posts.

Video Hosting - Fedora 5 Server Configuration (Optimized for Dedibox servers)


Video Hosting - Fedora 5 Server Configuration (Optimized for Dedibox servers)
I found it quite hard to get up to date information on how to configure properly a video hosting server on Fedora.

Here is a quick tutorial to tell you every single step I used after setting up my server with fedora core 5 (bordeaux). My hosting provider is Dedibox. It is designed for beginners to follow the step by step; but advanced users will surely know which steps to skip !

This will help you installing:

    * Fmpeg (http://ffmpeg.mplayerhq.hu)
    * FFmpeg-PHP (http://ffmpeg-php.sourceforge.net)
    * Mplayer + Mencoder (mencoder is now built into the mplayer svn release )
      (http://www.mplayerhq.hu/design7/dload.html)
    * flv2tool (http://inlet-media.de/flvtool2)
    * LAME MP3 Encoder (http://lame.sourceforge.net)
    * Libogg + Libvorbis (http://www.xiph.org/downloads) 



Table of contents

    * Requirements

    * 1-click Setup

    * Setup explained



REQUIREMENTS

First, here are all the packages I needed on my fresh FRESH INSTALL of FC5

    yum install subversion
    y
    yum install ruby
    y
    yum install gcc
    y
    yum install ncurses-devel
    y
    yum install gcc-c++
    y
    yum install php*dev*
    y


You'll need the Livna repository to install mplayer so let's set it up now:

    vi /etc/yum.repos.d/livna.repo


Then in Vi, press the key "i" and copy and paste this:

    [livna]
    name=Livna for Fedora Core $releasever - $basearch - Base
    baseurl=http://rpm.livna.org/fedora/$releasever/$basearch
    http://livna.cat.pdx.edu/fedora/$releasever/$basearch
    http://wftp.tu-chemnitz.de/pub/linux/livna/fedora/$releasever/$basearch
    http://ftp-stud.fht-esslingen.de/pub/Mirrors/rpm.livna.org/fedora/$releasever/$basearch
    #mirrorlist=http://rpm.livna.org/mirrorlist
    enabled=1
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-livna

    [livna-testing]
    name=Livna for Fedora Core $releasever - $basearch - Testing
    baseurl=http://rpm.livna.org/fedora/$releasever/$basearch/RPMS.lvn-testing
    http://livna.cat.pdx.edu/fedora/$releasever/$basearch/RPMS.lvn-testing
    http://wftp.tu-chemnitz.de/pub/linux/livna/fedora/$releasever/$basearch/RPMS.lvn-testing
    http://ftp-stud.fht-esslingen.de/pub/Mirrors/rpm.livna.org/fedora/$releasever/$basearch/RPMS.lvn-testing
    #mirrorlist=http://rpm.livna.org/mirrorlist-testing
    enabled=0
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-livna


Save your file by pressing "esc" and:

    :wq


Once Vi exited let's import the GPG Key for this repository:

    wget rpm.livna.org/RPM-LIVNA-GPG-KEY
    rpm --import RPM-LIVNA-GPG-KEY
    rm -rf RPM-LIVNA-GPG-KEY

Getting a feel for the network with ‘netstat’


It seems that my previous article, “Getting a feel for the network 
with ’ss’” was pretty popular. ss is a great tool but isn’t always 
part of a base install for your favorite version of Linux. With 
that in mind, let’s talk about how to do some things with tools
that are more likely to be part of the base. This time we will 
discuss netstat and next time we will cover just the tip of the 
iceberg that is lsof.

Our tricks for the day:

    * Get a list of active TCP connections

    * Get a list of active TCP connections and resolve hostnames of IP addresses in question

    * Get a list of listening TCP sockets

    * Get a list of TCP connections in various other connection states

First netstat:

Get a list of TCP connections (in this case, we include “listening” TCP ports):

$ netstat -ant
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 127.0.0.1:631           0.0.0.0:*               LISTEN
tcp        0      1 192.168.253.101:52812   74.52.160.50:80         FIN_WAIT1
tcp   509792      0 192.168.253.101:49200   38.119.55.141:80        ESTABLISHED
tcp        0      1 192.168.253.101:52813   74.52.160.50:80         FIN_WAIT1
tcp        0      0 :::22                   :::*                    LISTEN

As before, except this time resolve the IP addresses in question:

$ netstat -at
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 localhost:ipp           *:*                     LISTEN
tcp   509792      0 chaco.local:49200       rieko.ziaspace.com:www  ESTABLISHED
tcp        0      0 *:ssh                   *:*                     LISTEN

In the previous commands we showed active TCP connections but also TCP
ports that were in the “listening” state. If you are messing with 
netstat and lsof then you are probably at least somewhast familiar 
with IP networking but, if not, listening basically means that some 
process is ready to accept new connections on that port.

In this command we are going to show only TCP ports that are in the 
listening state and not active TCP connections. Note that, as in my 
previous article, the only processes listening for new connections 
on my workstation are the SSH and CUPS daemons.

$ netstat -tl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 localhost:ipp           *:*                     LISTEN
tcp        0      0 *:ssh                   *:*                     LISTEN

Now for our final netstat trick, we are going to list all of the TCP 
connections where a TCP SYN packet has been sent but the receiving end 
has not yet replied. See Wikipedia for more information about the TCP 
handshake. I’ve fired up a Gnutella client so that we have lots of 
interesting TCP connections in the output:

$ netstat -tl | grep SYN
(Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.)
tcp        0      1 192.168.253.101:59227   142.217.112.185:2729    SYN_SENT   7542/gtk-gnutella
