Migrating CQRLOG from one PC to another

I had to do this just now and I thought I would document it (at least for myself) and maybe it will help others.

This probably isn't all the things everyone might have to do but it works for how I use CQRLOG

I use Fedora 16 x86_64
I use the binary release of CQRLOG "Complete application directory"
I mostly just use CQRLOG to log my contacts and upload them to LoTW, nothing else (so far)
I use CQRLOG 1.3.0

Install dependencies

yum install openssl-devel (needed for LoTW upload support)
yum install hamlib
yum install mysql-server (interesting this binary release of CQRLOG uses distro provided mysql but starts it manually, so you do NOT need to do 'systemctl enable mysqld.service')
yum install trustedqsl

run tqslcert and load your .p12 certificate file
run tqsl and readd your location with the same name as on the other computer

tar up the .config directory for cqrlog from the original computer

tar -cjvf /tmp/cqrlog-backup.tar.bz2 ~/.config/cqrlog/

transfer the cqrlog-backup.tar.bz2 to the new PC and extract it
cd ~/
tar -xvf /path/to/cqrlog-backup.tar.bz2

Download cqrlog_1.3.0_amd64.tar.gz from http://www.cqrlog.com/?q=webfm_send/222/1

cd ~/
tar -xvf /path/to/cqrlog_1.3.0_amd64.tar.gz
run cqrlog as normal

~/cqrlog-1.3.0/usr/bin/cqrlog

All should be good.

Creating a QSL card in Inkscape

So since I've become active in ham radio again I have been working 17 meters SSB pretty regularly. The other day I worked a French station F2FG and apparently he needs North Carolina for his Worked All States (WAS) award. I know this because he sent me his QSL card requesting I send him mine to confirm the contact, specifically mentioning WAS. Well that creates kind of a problem because the only QSL cards I have are from when I lived with my parents in Wilmington and I don't live there anymore, plus those cards were ugly anyway!

So I have some free time on my hands and I got started using the Free and Open Source vector graphics editor, Inkscape. I was familiar with this tool and wanted to give it a shot so I went through some tutorials and went at it. I was picking it up alright but I had some issues so I asked my friend Patrick Connelly who has done some work for me in the past with it for some help. He whipped up a template for my required size which I had measured from other QSL cards I had as either 5 1/2" (w) x 3 1/2" (h) or 140mm (w) x 90mm (h). What I had been doing was making the page layout as small as a single card. I asked Patrick how I would want to store this for printing, ie one file with both sides or two separate files.

HP Touchpad and Preware to improve performance

My buddy Michael picked up an HP Touchpad at $99 and gave it to me for my birthday. I have been enjoying it a lot. At first it seemed too heavy to be a tablet. I thought you were supposed to be able to hold tablets with one hand comfortably but this one needs two after an extended period of time or it needs to lean against something.

Recently some of my friends who have had the Touchpad for a bit longer than me suggested I install Preware so I could install the Uberkernel which increases the CPU clock from the default of 1.1 GHz to around 1.5 GHz which is apparently what the CPU is rated to run at anyway.

My friend Adam created a great Preware setup guide on how to do all this.

I did run into one main problem which was installing the WebOS SDK since it is only distributed for Windows, Mac and Ubuntu Linux in deb format. Since I'm on Fedora 14 I can't use deb. I got around that with alien...

Boxee Box is a Disappointment

The boxee box has been quite a disappointment. I've said it before, but it really is annoying when boxee, based on XBMC is less usable than it's roots, and then netflix dies(even after restoring/reflashing and upgrading), and to add insult to injury I can't modify the open source software on the box, or put anything else on it (like xbmc). If it's going to be as limited as proprietary software I might as well have a proprietary box that works.

NetworkManager, bridging and VPN

I cannot get this to work.

in /etc/sysconfig/network-scripts/ifcfg-eth0 as soon as I add this
line and save it NetworkManager stops managing eth0

BRIDGE="br0"

Then if I click on the nm-applet the VPN option is greyed out and
unclickable. It also shows "wired networks

[root@farina network-scripts]# cat ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="none"
HWADDR="00:24:8C:6C:31:DF"
NM_CONTROLLED="yes"
ONBOOT="yes"
BRIDGE="br0"

[root@farina network-scripts]# cat ifcfg-br0
DEVICE="br0"
BOOTPROTO="dhcp"
#HWADDR="00:24:8C:6C:31:DF"
NM_CONTROLLED="no"
ONBOOT="yes"
TYPE="Bridge"
DELAY="0"

I don't see how this can work?

I thought about letting eth0 do dhcp and that worked, but as soon as i
enable BRIDGE="br0" in ifcfg-eth0, network manager stops managing it..
(check the screenshot)

I wonder if I create the bridge manually if networkmanager would work on eth0.

Hannah Montana Linux is Real

Hannah Montanna Linux, You might think it's a joke, but the author claims it was created to entice young people into using Linux. I fired it up in a VM and it is actually real. It took me a while to find a torrent link that works so I'm attaching the torrent I used here. Here are some screenshots. I didn't actually get it installed because I accidentally only made my KVM guest's disk image 1000 MB and by the time the install failed I was ready to go to sleep, but I did get far enough to get some screenshots of the installer (including syslinux boot splash screen!) and the live CD functionality to get a feel for it. It is real.

Red Hat Enterprise Security: Network Services and RHCA

Yesterday I passed the Red Hat Enterprise Security: Network Services Exam (EX333). It was the last certificate of expertise I needed to complete the Red Hat Certified Architect program. On the first part of the exam I made a typo configuring a major service which caused me to lose a lot of time. After trouble shooting it for a bit I moved on to other things and after I completed the other items I came back to it and finally figured out my mistake with only forty five minutes left. I managed to get that major service and all it's associated services setup after that but had no time to reboot and verify they were all still properly configured. I had some trouble on the second part testing my configuration (I was not testing properly, it actually worked fine) but I lost time there too. In the end I wish I would  have practiced more but either way I got it and I'm pretty psyched:

Banshee and Amazon MP3 Downloader

I've always been annoyed when using Amazon MP3 Downloader to download full albums from their site because the RPMs provided are always only usable on older distributions (at least in the Fedora realm) so I was glad to see Banshee on Fedora 14 supporting AmazonMP3 Downloader within the app! Take a look:

Cacti Is Awesome!

I have been using MRTG for a while but I always wanted graphs for more than network statistics. So I finally setup Cacti this week. It took me several nights of configuring but I finally got it setup like I want for my home network. The key for me was installing these cacti templates from Alexandre Dumont. I modified them slightly, and I may document the whole process on a friend's wiki later.

EX442 Systems Monitoring and Performance Tuning

I got another Red Hat Certificate of Expertise. Here is the course outline so you can see material covered by the course/exam RH442 outline. Now I only need to pass the EX333 Red Hat Enterprise Security: Network Services to get my RHCA! I've taken (and failed) the EX333 before but on the plus side I know what to expect, so next time I will prepare properly and I feel confident I can pass it. I'm signed up for the RHS333/EX333 in November..
