Brian Trapp of Linux Journal recently wrote an article on how to create a perfect Raspberry Pi home server. The article talks about how to install an external USB drive, a Samba server for backup, a DLNA server, and a print server. The article is quite straightforward and easy to follow.
Scanners can be a nightmare to work with. I’ve had this Canon MP495 Wireless Printer/Scanner for at least 3 years now. The wireless printing works on all my Mac computers, but I can’t get the device to scan via the wireless network. I even downloaded the latest Canon drivers as well as the latest MP Navigator software, but to no avail.
The solution seems rudimentary considering all the recent improvements in software and on network devices. The only solution that I have gotten to work is to connect the scanner directly to my Mac Mini via a USB port. In addition, the Canon MP Navigation software doesn’t seem to be scanning. I ended up using the Scanner software that comes with the Mac OS.
I stumbled on the Sphirewall Project the other day. Sphirewall is an open-source Linux firewall to compete with Iptables, Smoothwall and Monowall. The following are excerpts of the Sphirewall website.
Sphirewall is an open-source Linux firewall and router that provides advance user management and bandwidth analytics coupled with powerful flexibility. It’s open-source, free, easy to install and built from the ground up not using iptables.
Check out the features below
- Full NAT/PAT and ip filtering support
- User authentication and group based filtering
- Detailed analytics and reporting on network traffic
- Web, commandline and json api based management
You can download the debian iso, burn it to a cd, usb stick or mount it in your favorite virtualization system and get it running in minutes.
BART union employees went on strike for 5 days. At the end of the strike, there is no new contract and no progress. Both parties are as far apart as they were before the strike. Bay Area commuters were irked due to long lines, extended commutes, and lost productivity. The only reason the strike was ended is because the BART union were feeling the heat and losing support from the public. Back to the drawing board. Back to square one. What was accomplished from the last five days? Absolutely nothing. Instead both parties agreed to continue negotiations and extend the current contract for a month. They could have done this and averted a strike. Meanwhile, who pays for the millions of dollars in lost productivity? If you are going to strike, at least show some backbone without losing any of your bargaining power. That’s a fail in my book.
Just two days away from the Fourth of July. Some of you may be watching fireworks with a camera on hand. National Geographic has some photography tips on how to photograph fireworks.
Set your camera to manual mode. Use ISO of 100, f/11, and 1/2 second. If it’s too dim or too bright, you can vary the shutter speed but keeping the aperture the same.
And lastly, don’t forget to post your best photo online.

Google plans to roll out Google Fiber to 14 cities. 12 cities in Kansas and Missouri have already struck a deal. Provo, Utah and Austin, Texas were recently added to the list.

So, 2 cities down and 998 more to go.
If you have multiple domains installed in a virtual host configuration with one IP address in Apache, the IP address may not resolve to the domain you prefer. Let me explain.
For example, you have the following domains running on an Ubuntu Server with one IP address.
abc.com cde.com klm.com xyz.com
All the domains are resolving as expected on the browser.
However, if you type the IP address on the browser, it only defaults to the first domain found in the /etc/apache2/sites-available directory, which is most likely abc.com.
If you want the IP address to default to another domain, such as klm.com for example, you will need to edit the /etc/apache2/httpd.conf file and add the following entries.
<VirtualHost *:80> ServerName www.klm.com ServerAlias klm.com DocumentRoot /var/www/klm.com/www </VirtualHost>
Those are the only entries you’ll need. Typing the IP address on the browser will now default to the contents of klm.com. All the other domains are still accessible via domain names on the browser.
There is a conflict between the Twenty Twelve WordPress and the All in One SEO Pack plugin. When the plugin is installed and you happen to be using the Twenty Twelve theme, the result is, there will be no space between your site title and blog title. You’ll notice this if you look at the title bar of your browser. After a couple of searches, I found a fix online. It involves editing the Twenty Twelve functions.php file and commenting out line 185 which contains the code below.
You will need to change:
add_filter( 'wp_title', 'twentytwelve_wp_title', 10, 2 );
and comment out:
// add_filter( 'wp_title', 'twentytwelve_wp_title', 10, 2 );
Also, you need to clear your browser cache to see results.
