Data Recovery Using FreeNAS

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
tcp        0      1 192.168.253.101:36291   74.193.252.111:37998    SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:36874   12.210.29.230:53781     SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:35878   69.245.72.170:2500      SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:33314   24.94.77.8:50345        SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:43488   24.238.218.203:1334     SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:53485   24.95.79.143:1128       SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:60224   69.133.19.41:24536      SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:52441   72.51.246.127:4379      SYN_SENT   7542/gtk-gnutella
tcp        0      1 192.168.253.101:57700   70.80.99.180:23112      SYN_SENT   7542/gtk-gnutella

Okay, that’s it for today. If you want to do some extra credit then I suggest 
looking at the ‘-p’ flag for netstat.

Spyware Removal guide

Spyware Removal guide

For those that don't know, spyware is bad, spyware is really bad. It also has many different names. Like adware, malware, badware, trojans, worms, downloaders, junkware, etc. Whatever you call it it's bad and you need to know how to get rid of it. The most common method people use to remove spyware is to download some software from Download.com and run that to remove the spyware. This method works ok most of the time but it usually takes much longer than I would ever want to spend on a computer. This spyware removal guide presents a much faster more effective way.

To understand how to deal with spyware you first have to understand how it works. It gets on a computer by attaching itself to, or disguising itself as, some useful piece of software. Kazaa is the classic example of that It is a useful piece of Peer to Peer software but it is packed full of spyware. The first thing that spyware does when it is on a computer is add itself to various parts window's registry so that it will be loaded when windows starts up. So the first thing you need to do is removed these various registry entries so that you can then remove the spyware.

To do this you will need to use some cool software. The first cool software you should use is called msconfig. It is installed standard on Windows XP, Windows ME and Windows 98. It is not included with Windows 2000. Don't ask me why. I always run this right off before I do anything else. To access it all you have to do is click the Start button. Then click on Run and type in "msconfig" and click "ok". You are greeted with the System Configuration Utility. You can disable most start up items by clicking on "Selective Startup" and uncheck "Load Startup Items". If you do this most of the stuff that normally starts up will not start up when you reboot your computer. Then go to the Services tab and Disable all non-Microsoft services. Don't be timid in disabling anything in this utility. There is nothing you can do that will permanently damage Windows because you can always come back to this utility and undo your changes.

After you have ran msconfig I would reboot the computer into safe mode. You can do this by pressing "F8" while windows is starting up. Sometimes it hard to know when to do this. It's after your computer goes out of the bios and boots off the hard drive you should press F8. If in doubt repeatedly press F8 while the computer is starting up. The advantage of being in safe mode is that none but the cleverest Spyware is loaded in Safe Mode. In safe mode it is time to try the powerful program known as HiJackThis.exe. HiJackThis functions like msconfig but it is much more thorough at finding possible spyware problems. The rule to follow when using HiJackthis is, "If you don't know what it is get rid of it." When you run a scan with HiJackThis you will be presented with a list of possible spyware found in the registry. Keep in mid that it is possible spyware, just because it is there it doesn't mean it is bad. Most of the stuff listed here will be extensions to Internet explorer and stuff like that. Everything listed is optional. Your computer will work perfectly fine even if you removed everything listed. Once you check those things that you want to remove and you click "Fix Checked", restart your computer in normal mode and you should have about 90% of your spyware removed.

To find out if you have successfully removed all the spyware, start HiJackThis again and do a scan. If you find anything listed that you had previously removed that means that the spyware is still on your computer somewhere and has come back to plague your existence. At this point it is hard to give you an exact procedure on how to remove the remaining spyware. Probably the easiest thing to do is download a good spyware scanner and run that. You can see a list of the ones I recommend at the Spyware Scanners page. If the spyware scanners still fail to remove the spyware than you'll have to find a more involved procedure. A sure fire method of removing a known spyware file is by booting into an entirely different operating system and manually deleting it.

When you ran HiJackThis you probably noticed a file name associated with. This is most likely the file that is run when windows starts up that activates the evil spyware process. If you thought, "I'll just delete this file." It would be a great idea but if you tried to do so you probably came across the error, "Access Denied, file may be in use" or something like that. Don't ask me why but Windows is unable to delete a file if it is in use. There is absolutely no reason why this has to be the case. I have no problems deleting executables of running processes in Linux. Anyway, to delete this file you need to boot the computer from a different medium, the most convenient is probably a CD. The best type of bootable CD for spyware removal purposes is probably Bart's PE. You can find information on how to build a bootable CD with windows XP and spyware removal tools here.

If you took a look at that you probably noticed that it was a rather complicated procedure. It is quite possible that you already have a boot CD that will do what you need to do. If you have a windows Installation CD you could boot from it and then press 'r' to enter the recovery console. Sometimes it will ask you for your administrator password. If you don't know it try just pressing enter. If that doesn't work see Windows Password Recovery Guide for information on how to reset administrator passwords. Once you are presented with a prompt you can issue DOS commands like, "del /Path/to/file/filename.exe" to remove the offending file that you found with HiJackThis.exe (you did wright that file name down, right?).

Hopefully this spyware removal guide has helped you get your computer working as good as the day you purchased it. Of course this all would have been avoided if you had just used Linux. Don't forget to check out Spyware prevention once you get all the spyware removed.
