Well, I finally upgraded all four systems to Jaunty Jackalope. I did the upgrade in pairs so that the entire network wouldnt be offline. I spread it across two days. I used the tutorial from UbuntuGeek to upgrade via the konsole. It was mostly painless, with my laptop being the most troublesome. Having to re-configure a separate network manager, that wasn’t immediately visible, was a nuisance. I had to add a widget to the panel and then configure the widget. I would have preferred to keep my connection.
Now that I’m using a larger network, I’m attempting to connect my systems in a semantic interface using IRC. I’ve found that Quassel’s backlog system enables me to monitor multiple channels in one window and that’s pretty helpful. To top it off, I found you can connect it in a multi-user setup by configuring multiple users on the Quassel Core . Of course, centralizing this and delegating it to a server that is in less demand with fewer resources, worked perfectly for me. It simplified the backup and freed some resources across my net.
This is my first post mentioning Quassel, but it will not be my last. I am going to skip the really significant features that Quassel brags about (with much reason), but point to this lovely screen shot. It demonstrates how Quassel shows a tiny preview of a link beneath your mouse cursor, keeping you from having to open your browser to view a site that you may not really desire to visit.
I use the command line more than anything, and I try to stay up to date regularly, so I added an alias for the command I use for updates.
alias apt-up='sudo aptitude -y update && sudo aptitude -y full-upgrade '
Recently, I have had a need to use Windows more frequently (Windows-only games and ActiveSync!), but still have a high demand on my network at the same time. I have sought to be able to combine the best of both worlds. I previously relied heavily on Web-based applications, but my favorite Web Development IDE was developed for Linux only. I had put up enough with the banalities of using WebMin and it’s built-in file editor. I have read about others having success running KDE apps on Windows, but since I had my Quanta already setup and configured, I looked for a way of just being able to access that. Honestly, I’m not very excited about using VNC over WiFi, even with high compression.
To my surprise, I found that Xming was specifically suited to my needs. It acts as an X11 server, allowing me to use it to display my X11 applications that I have forwarded through SSH. It works perfectly.
It took a little time for setting up, but if you have got PuTTY installed and working, sixty percent of the work is already done.
Below is a screen shot that shows my running Windows Vista desktop, programming in Quanta which is actually hosted on a server called A. This is connected through an SSH tunnel from my laptop to my C server using the Putty client. From the C server, I launch the Quanta program using another SSH connection to the A server. It looks just like the Quanta program is a native windows app on the local Windows Vista desktop. You’ll also notice I’ve got an xterm session open connected to server A in the background.
I’ve resisted too long. Finally I was coerced into it. After having spent a lot of time on a different project, I’ve tried to spend a little more time in KDE 4, and then Konqueror stopped working. It would give me a fatal error every time i tried opening. I found someone else reporting the error and it had been suggested to go ahead and upgrade KDE. I checked for new packages in Hardy Heron, but none were available. The upgrade from the run prompt using
kdesudo “adept_manager –dist-upgrade”
After a successful install on the machine that has the most packages, I chose to repeat on the other machines. Yay, I’m able to use Konqueror again.
I’ve also been very happy with some of the other improvements. While I was disappointed to see that KDE3 is missing, KDE4 now supports saving sessions and locking the terminal. Both were my biggest complaints aside from crashes.
I recently learned of a font that other users highly recommend for your terminal application. Being a demanding Konsole user, it sounded beneficial so I thought I should try it. I have, and I think I am happy with it. You should try it out. Here are the instructions on how to install it in KDE 3.5. It is called the Terminus font, and I found a TrueType Font format file at this site. To install it in Kubuntu Hardy, I went to Kmenu -> System Settings ->
Font Installer ->
I then selected the files I downloaded from the previous site. Then, from inside of Konsole I went to
Settings -> Font -> Select and chose the Terminus font.
And now here is what my terminal looks like:
Please share your thoughts and any suggestions!
In honor of the upcoming release of Intrepid Ibex, Bauer Power is returning Ubuntu or Kubuntu stickers to people who mail him a self-addressed stamped envelope. I mailed my request today! He said his mailbox was full. I wonder if he’s been able to fill all of the requests. I’d like to drop a note of thanks to him for this kind of gracious offer. Here’s another example of the fine people in the open-source software community.
Thanks Bauer Power!
I discovered the best way for me to mount my ssh shares via sshfs automatically when I log in. I add shares and folders from time to time, and I also wanted this technology to automatically be backed up for me, so I wanted the solution to lie inside my home folder. I did some research and learned that KDE has an Autostart folder. For KDE 3.x this is currently at ~/.kde/Autostart, and for KDE4 it is ~/.kde4 (which will eventually drop the 4). I’m already hosting my scripts in ~/bin, so I created a script in that folder to execute sshfs and create the mounts. I then created a link by right-dragging the icon in Konqueror from the ~/bin/ folder to ~/.kde/Autostart. This will work for any executable or script. Now my sshfs mounts automatically at login.
I started encountering an error when using kdesu via SSH after Hardy Heron was installed. I’ve since upgraded to 8.04.1 as well and still am running into this bug.
X11 connection rejected because of wrong authentication.
kate: cannot connect to X server localhost:10.0
I know I’m not the only Kubuntu user, and there is proof I am not the only user encountering this error. I’ve been getting around it by using gksu which has no problems with my authentication. I suppose I could just alias kdesu and kdesudo (i tried it with no luck too!) to gksu, but I’d like to see an update fix this in the upcoming months. The nice fade effect of gksu is a welcome change sometimes.
