For those that have never used crontab, it can be a daunting task to schedule a simple script. As with all things, I highly recommend that you learn the meanings of CLI programs and their usage etcetera. With that said, I wanted to check my crontab job against a generator of sorts just to be sure I had it right. If you want a simple click and go on crontab generator, I recommend using the one provided by HTML Basix. Enjoy!

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)

Why Linux and open source matters for small businesses and schools Hans Knobloch, Philadelphia Information technology Examiner
This blog was shared with me last night and I think the points made for using open source (linux) are right on target. The general public may or may not choose to accept this but business use of open source products continues to rise. Especially in this economic climate. (the reason this blog was started!) A quick Google search will reveal that there is an open source tool for just about any business need. This means freedom from initial software purchase, recurring license fees, etc.
Rockin’ on without Microsoft David Becker, Staff Writer, CNET News
This post is from 2003 and shows that even six years ago it was possible to convert to open source and continue as a successful business. It is easier today.
Linux is no longer relegated to the dark recesses of IT Geekdom. Major hardware vendors sell desktops and laptops pre-loaded with various distributions of Linux. A non-technical co-worker recently bought a mini-notebook loaded with Linux “because it was cheaper” and learned how to use it.
As virtualization projects grow in the SMB and education markets, there is often a natural progression towards open source related tools. Advanced configuration and troubleshooting of VMware ESX or Citrix XenServer hosts requires understanding and use of SSH and linux-based file systems.
Quoted from the blog post:
” Here are some facts about free and open source software and Linux:
- A typical Linux and free open source software equipped PC will cost up to 60 – 70% less to operate over a typical three year write off time.
- A typical PC hardware suited for Linux does not need to be as expensive as a typical Windows or Mac OS X PC. Linux requires much less resources. As a result, Linux PCs have an extended average lifetime.
- Linux with typically installed quality programs, used for graphics, office, music, and Internet, are freely available as downloads from the Internet.
- Linux versions, like Ubuntu, come with a host of no charge business software.
- Pre-configured Linux versions, like the Ubuntu derivate Edubuntu, come with a host of no charge educational software, including teacher and student administration programs.
- Linux installations can be upgraded and maintained without additional costs – ever.
- Linux is much more stable and usually safer than its proprietary alternatives.
- Linux is much less virus endangered than Windows or Apple OS X.
- Linux is easy to learn and behaves in many ways just like Windows or Mac OS X.
- Company specific software solutions are available where needed from commercial vendors.
- Vendor supplied or vendor independent support programs are available if the need for professional support arises.
- Hundreds of Linux end user and administrator forums on the Internet provide cost free support, configuration and installation how-to information, and help desk services.
- Linux, with its open source character, is ideally suited to teach students the working of a modern computing system, better then any of its proprietary competitors. “
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.
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

After a clean install/upgrade of Ubuntu 7.10 (Gutsy Gibbon) you may be unable to get gdesklets to run. I have noticed several threads out there with no resolution so I thought I would post a fix. Most users will get the app installed successfully but when they run the gdesklets shell, the app begins to load, goes gray, and then has to be closed using force quit. Also, running gdesklets start from a console shows that the daemon is starting but it never does. By default Gutsy Gibbon uses Python 2.5 while gdesklets is looking for 2.4. This is pretty straight forward to resolve using these steps. Install python2.4 by running sudo apt-get install python2.4 from a console. After that is complete we need to tell gdesklets to use Python2.4. From the console we need to add a few entries to the gdesklets config files. Locate the line that says “#! /usr/bin/env python” and append it with a 2.4. So each line should now look like “#! /usr/bin/env python2.4″. This line needs to be updated at the top of each of the files listed below.
/usr/lib/gdesklets/gdesklets
/usr/lib/gdesklets/gdesklets-shell
/usr/lib/gdesklets/gdesklets-daemon
/usr/lib/gdesklets/gdesklets-migration-tool
After updating the files with your favorite text editor, start the app by running gdesklets start from a console. This should have you up and running in no time.
