Mozilla Sunbird is a calendar project that’s being designed as a sister program to Thunderbird and Firefox. It’s now at the 0.5 version, and there is a plug-in that integrates Sunbird with Thunderbird, called Lightning. It allows you to not only have a calendar, but send and receive meeting requests as well.

I’m running Thunderbird 2 under Ubuntu Feisty Fawn (7.04) on the AMD64 architecture, and could not find a pre-compiled version of this that worked. So, I decided to give it a shot. It was pretty easy, and the result is a plug-in that works with the AMD64 version of Thunderbird! Since I had trouble finding it, I thought I would share it.

Since I have just started using it, I haven’t wrung it out, or tested all the options. Use at your own risk, etc.

You can download the plug-in here. Happy storming!

When I ran Windows as my desktop, I had a program called WebShots that I used to set my desktop wallpaper, and cycle it. They have Windows and Mac versions, but no Linux version yet. They still send me e-mails each week, showing the daily picture selections for each day in the past week. I decided to download the Windows version, and install in under wine to see if it would work. I moved “websamp.exe” to /home/summersd/.wine/fake_windows, then ran “wine C:\\websamp.exe” to install the program. “wine “C:\\Program Files\\Webshots\\Launcher.exe” ” then started the desktop control. I used that to disable the tray icon (wine has one, but you can’t see it), and I disabled almost every other “auto update” feature.

I had downloaded a “.wbz” file (which is what is imported into WebShots), and I finally figured out how to import it. Running the launcher program, and following it with the name of the .wbz file, imports it. I may figure out a way to automate that, but for now, I know how to do it.

(Note: This is the end of the “My Linux Adventure” series of posts. After this, I ended up going back to Windows XP, just because it worked and I didn’t have hobbyist time. As of May 2007, I’m running Ubuntu 7.04 on one computer, and Windows Vista on my laptop, which is currently out of commission.)

I was finally able to resolve my problems with Apache and MySQL. When I decided to mount my FAT32 drive under /home/summersd, I inadvertently caused myself some problems. From talking to a Linux guy at work, I found that no processes that weren’t running under my user ID could access those files. The reason is that Linux looks up the entire diretory tree, back to /, to determine if you can access the file. So, although I had “-rwxrwxrwx summersd summersd” on every file, /home/summersd was “drwx—— summersd summersd”, and /home was “drwxr-xr-x”. The permissions on /home/summersd was keeping Apache from seeing /home/summersd/drive_d/wwwroot, and MySQL from seeing or writing to /home/summersd/drive_d/mysql/data. I moved the drive to /mnt/drive_d, with the mount point being owned by “root”, still mounting the drive with my user name, and everything worked.

In the process of reconfiguring Thunderbird, I believe I may have found out how to share the address book across operating systems. The file ~/.thunderbird/default.[something]/prefs.js has a listing of all the preferences and settings. I modified this file to change the location of my mail files, and there is a setting there for an address book (which isn’t shown in the configuration dialog - after all, it is 0.7.3…) I’ll play with that later - right now I’m just elated to have Apache and MySQL working again.

foobar2000 is about the best, most organized audio player I’ve found. However, it is a Windows application, and according to what I’ve read, very reliant on Microsoft C++ extensions. I decided to give it a shot under wine, and it works great! There is a repaint problem - sometimes the playlist doesn’t refresh as it should. But, it’s pretty much a start-and-minimize sort of application, so that’s acceptable.

We’re speedily working towards a Friday deadline at work, so tonight I had some analysis work to do on some COBOL code. Great, I thought, I can use my VSlick setup under wine. I moved my computer from the living room back to our now-empty bedroom (soon to be nursery), and booted it up. Kernel panics galore - never got past the network stuff. When I booted to Windows, I found that the wireless network didn’t reach that far, and I’m guessing that the ndiswrapper folks haven’t tried their driver a lot with a wireless card, but no wireless network. Once I get past that, I may grab the dumps from these kernel panics and see if the developers need them to see what went wrong. So, for tonight, I had to use WXP (in which I actually had to disable the wireless connection - seems Windows doesn’t handle a barely-there wireless connection much better than Linux).

The diagnostics I ran last night never found anything - they ran for about 10 hours. I suppose I’ll just have to wait until I have problems again, then run it right then. Another person from the WBEL users list suggested I check the way I have my hard drives set up; he thinks that a 2GB drive slaved to a 20GB drive may be causing conflicts, which would cause freezes or panics.

At work, we use an editor called Visual SlickEdit (VSlick). It’s got a lot of features, and supports color-coding for many different languages. I decided that I’d give wine another shot, as we only have the Windows version of this program. I installed wine and winesetuptk, used winesetuptk to configure the installation, then ran the installation program. Everything installed, and the program ran up to a point, when it started complaining about a missing DLL. I booted to WXP, found the DLL, copied it to the FAT32 drive, rebooted to Linux, and copied the DLL into the “fake windows” system directory. Soon, it was working great! I can’t believe it - success with wine!

I also have made little headway towards getting Apache and MySQL to working. I changed the process that Apache uses to run as “summersd”, and I was able to see pages (although any pages that relied on a database didn’t work). I still haven’t figured this one out yet…

I’m still getting kernel panics from time to time, and it seems to be whenever I access networking. A suggestion from one of the folks on the WBEL users list was to download the Ultimate Boot CD, filled with diagnostic programs. I downloaded it, burned it, and ran some memory checks. Those checked out, so I’m going to run a “CPU Burn-In” program to see if it can detect errors from the CPU. It runs for up to 7 days, but I think I’ll just run it overnight - folding@home didn’t take nearly that long to crash it before.

I downloaded xine and xine-ui again, just to get the freshest stuff. Compiled first time, worked first time. I must be learning how to do this stuff! I also did a “yum update” to get the most recent version of everything, and I upgraded ndiswrapper from .8 to .10.

I moved the computer into another room, and found that I was now getting conflicts on my wireless card. After some research, it appears that I’m picking up my next-door-neighbor’s wireless signal as well. I renamed our wireless network, and configured the cards to use only that network, and those conflicts went away.

Today, I reinstalled WBEL 3.0.  I was able to compile ndiswrapper (as I kept that on my FAT32 drive), and get the network card working smoothly very quickly.  (In fact, it seems to be more reliable under Linux than WXP!)  With the network up, it was easy to download Firefox, Thunderbird, and OpenOffice, and installing them was a breeze.  (I decided to put them under /opt this time, trying to stick with the FHS.)  I decided to mount my FAT32 drive under my home directory, as /home/summersd/drive_d.  E-mail works fine, but Apache gives me a 403 (Permission Denied) error.  MySQL doesn’t seem to be working either - I’ll have to play with that later.

Well, the last month has been interesting. I was able to get my Windows and Linux installations synchronized by creating a mount point for my second drive under /mnt/drive_d . Under that, I created a directory called /thunderbird for my e-mail, and moved my e-mail and newsgroup folders over there. (The first time, I missed the “newsrc” file, which is important - it tells what newsgroups you’ve subscribed to and which messages you’ve read.) Under Windows, I pointed it to “D:\thunderbird\pop3.knology.net”, and under Linux, it was configured to “/mnt/drive_d/thunderbird/pop3.knology.net”. I then moved the “wwwroot” directory from “C:\Inetpub” to drive D:, and pointed IIS to the new location. Under Linux, I did something a little different. As “root”, I deleted the directory /var/www/html, and instead created /var/www/html as a symbolic link to /mnt/drive_d/wwwroot (the actual command is “ln -s /mnt/drive_d/wwwroot /var/www/html”). That worked great as well.

MySQL was more complicated, but I was eventually able to get it working as well. I created the directory “D:\mysql\data” for the data, then configured /etc/my.cnf under Linux to look at “/mnt/drive_d/mysql/data”. I kept getting “Could not connect to server using socket /var/lib/mysql/mysql.sock”. After some digging, it appeared to be a permissions problem. All the documentation said that the default socket was /tmp/mysql.sock, so I changed my.cnf to point there instead, restarted mysqld, and it worked! So, I have no idea what a Unix socket it, but I know that now I have one!

I was also able to get DVDs playing using xine, compiling it myself, and using libdvdcss, I can even watch commercial DVDs. I’m really impressed with xine - it handles all kinds of media out of the box, including DivX and up to version 8 of WMV files. You can add codecs to it as well, to support almost anything you want to do from an audio or video perspective. Compiling the player took around 20 minutes, and compiling the front end took another 5. And, it was simple - download the .tar.gz file, do “tar xvfz [name].tar.gz”, “cd [name]“, “./configure”, “make install”. The “./configure” script is the key in the whole process - it looks at what you have installed, and creates make files that will work with your compiler.

Everything started going south, though, when I started having freezes. Eventually, I got to where I could not boot without a kernel panic, and then boot errors (which I detailed in this e-mail to the WBEL user’s list. Encouraged by my success over the past month, I decided to return to WBEL - it’s supposed to be more stable than FC2, and I bet that I can get ndiswrapper, the dual-booting web server, the common e-mail, and maybe even some other stuff working again.

Today I installed Fedora Core 2. This thing is slick! WBEL looked a lot like RH8, which I had seen before my renewed Linux learning began. FC2 has a graphical loader that hides a lot of the background stuff (unless an error occurs) - that’s cool. During the install, I skipped OpenOffice.org and MySQL, although I installed PHP with MySQL support. The reason for that is that I wanted to get the latest and greatest versions of those two products. We’ll see if this proves to be a good decision or not.

The wireless network card still wasn’t recognized (phooey). I did some more searching, armed with the knowledge that I have an adm8211 chipset. One of the first hits under Google’s Linux search for “adm8211″ pointed me to a project called NDISwrapper. This is a “wrapper” that uses the vendor’s Windows DLL file, and converts the hooks from Windows to Linux. Doing this, this driver can (in theory) support most any network card, especially those that aren’t in the Linux Hardware Compatibility List (HCL). I downloaded it, compiled it, and followed the directions to install my driver under it. I still wasn’t able to create a connection, but on a hunch, I restarted the computer. NDISwrapper is also a kernel module, and I know that often those are only read at startup. Once the computer was restarted, I was able to create a connection, and now my network card works! YEA!!! (And it was only one night’s worth of work - much better.)

Now that I have networking working under both operating systems, I plan to try to get four things working the same, whether I’m booted to WXP or Linux - E-mail (using Mozilla Thunderbird), PHP (using Apache on Linux, IIS on WXP), MySQL (using the exact same version on both), and a web server that uses the same html root directory (again, Apache on Linux, IIS on WXP). If I didn’t already have IIS up, running, and configured under WXP, I’d probably just do Apache on both, but this will be interesting - it should work, as I don’t have many creative permission rules.
