This week I joined the Ubuntu LoCo Florida Team and participated in last night’s team meeting (via IRC). Seems like a great group of people AND an excellent way to get more involved with Ubuntu (and really any Linux).
In addition to the IRC meetings, there are scheduled meetups to perform various activities such as installing networks for youth homes/schools, bug testing, documentation writing, and just plain fun. Anyone out there enjoy bar-b-que and beer???
I look forward to greater involvement!
If you have no idea what IRC is and need a Linux client to get started, I recommend xchat (sudo apt-get install xchat)

Just wrapped up another Ubuntu LoCo meeting. The meetings are fun, informative, and full of ideas. I am still truly amazed by the community efforts in open source project and Ubuntu is no exception.
You can join your LoCo anytime or idle in ours on Freenode @ #ubuntu-us-fl.

Recently, I converted a decently spec’d terminal server into an ESXi server after doing a P2V on the TS. After that, it was time to play. I installed a fresh copy of Ubuntu 9.04 server and then installed FOG. If you don’t know what FOG is, you may want to read FOG’s overview here. Once I got it all installed I kept getting an error when connecting to the web-based management interface. I have pasted in the error and resolution below, including credit on the source of the resolution.

Warning: mysql_connect() [function.mysql-connect]: Access denied for user ‘root’@'localhost’ (using password: NO) in /var/www/fog/management/index.php on line 34
Unable to connect to Database
I am not sure what else to tell you from here, I am at a standstill. Thanks for any help you can offer up.

All you need to do is go to /var/www/html/fog/commons/config.php and change the mysql password in that file you match whatever you set it as.
Original Post: Open Source Technology As Business Solutions: Openfiler – Symantec CPS Destination
We quickly noticed an issue with the iSCSI connector not automatically re-connecting the drive mapping when either the Openfiler server or the CPS server was rebooted. After some troubleshooting and most testing failed to resolve this issue, this project was scrapped in favor of using an Ubuntu NFS share as a backup2disk target.
Next step will be to test an NFS share as a CPS target.
For anyone that is not a Linux command-line expert (myself included!) webmin is an invaluable tool. A very quick install of this allows advanced administration from any web browser that can access the IP address of the server. Version 1.480 is the current release. Check it out and you will be pleasently surprised…
Instructions provided here are specifically for Ubuntu but can be adapted for any distro. (thanks to Himuraken for the proper syntax)
1.sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
2.wget http://prdownloads.sourceforge.net/webadmin/webmin_1.480_all.deb
3.sudo dpkg -i webmin_1.480_all.deb
4: open web browser, point to IP address of server on port 10000

Clearly Symantec is NOT open source. The solution to a common data backup problem can be found with open source tools however.
Issue: Backup2Tape provided long backup windows and an unreliable media. Soloution must use open source tools and existing hardware.
Solution: Ubuntu 9.04 (64-bit) NFS share running on Dell 2950 with six Seagate 1.5TB SATA drives in RAID5 configuration. Windows Services for Unix installed on Windows 2003 Server with Symantec Backup Exec 12.5.
NOTE: This will not work without this Symantec command: (verified in BE 11d and 12.5)
bemcmd -o116 -v -f”Name of your backup to disk folder” -e0 -m1 -d\\NFS-Server-Name\export-name
While the backup2disk is running fine, backups of Exchange Storage Groups are currently failing. All other data writes to the NFS share with no errors. Research continues…

Virtualization Lab: Part 2 – Concepts and Terminology
Welcome to part two of my Virtualization Lab series. If you haven’t read part one, I would recommend reading it first.
In this post I want to go over the concepts and terms that are used so frequently. Understanding the gist of virtualization will help lay a steady foundation upon which advanced topics seem more natural and intuitive.
Commonly used terms:
Host – This term is used to describe the operating system and physical computer that exists and runs virtual software/hardware.
Guest – This term is used when referring to a virtual computer or operating system which is running on a host system.
VM – a Virtual Machine is the same thing as a guest and is used much more frequently.
Hypervisor: A hypervisor is a lower level operating system that exists somewhere between the physical hardware and the VM’s. A hypervisor usually takes the place of your user system and is essentially a small highly optimized operating system for running virtual machines.
P2V: This acronym stands for Physical to Virtual. P2V conversions are great when they work and help convert current systems into a VM.
There are many other terms and acronyms out there, but these are the most common.
Where to start:
For the absolute beginner and most others, I recommend installing VirtualBox which can be downloaded here. Go ahead and get VirtualBox installed since we will be going over it in more detail in part three of this series. You will also need to download a .iso file for next weeks post. I will be installing Ubuntu 9.04 Jaunty Jackalope 32bit which can be downloaded from here.

I have been a user of Dropbox for about six months now and think that it is a great service. I have it installed and running on five systems, all of which run Ubuntu.
When Jaunty Jackelope was released a week ago, I decided to upgrade all of my Ubuntu boxes. While the upgrade went flawlessly on all five systems, Dropbox died. I went out and downloaded the latest version of Dropbox which has Ubuntu 9.04 listed. Reinstalling the package did not resolve the issue. So I started playing at the command line and realized that this is really easy to fix. Here is the fixed that I came up with:
Open up a terminal and type in dropbox status and you should see a message like Dropbox isn’t running!. If you try and run dropbox start you will get another error indicating that The Dropbox daemon is not installed! and the resolution which is to start with the -i option.
So the actual command to install the daemon is dropbox start -i. Once I ran that, the daemon and Nautilus extension launched and updated immediately.
Few people are aware of the command line use of dropbox. Play around with the utility and see what I mean. The dropbox filestatus command is pretty neat. Just run it from within your Dropbox folder.
