Ubuntu 10.04 - The Lucid Lynx has escaped!

Ubuntu 10.04 was released yesterday.  I've been Alpha / Beta testing it from the beginning.  It's been a fun ride and now it's rolling off the production line.  I really like the new theme and other features.  So far every thing works great with the exception of the Simple Backup Suite.  That application does nothing for me on Lucid.  I have discovered another great backup utility called deja-dup however.  It's late and I don't really have time to do justice to this entry, so I'll continue this tomorrow.  Good night.

Help my family please.

I lost my job on the 9th and I'm frantically seeking employment. If anyone would care to help my family, please click on the paypal link DONATE button if you can. I will remove this post when I become employed again.

Thank you for caring,

Charles & Joy Jackson

Installing Firefox 3.6 and Java 6.18

I was debating on weather or not to write this guide but since I have to keep recalling the steps for my own use, I'll post it here. This will be short and with little explanation since it's for my own use mainly.

For Ubuntu 9.10 (Karmic), open a terminal and paste the following:

sudo add-apt-repository ppa:mozillateam/firefox-stable

sudo apt-get update

sudo apt-get install firefox-3.6 <or close the terminal, and run the update manager>

---

For ubuntu 9.04 (Jaunty) Users

First you need to edit /etc/apt/sources.list

gksudo gedit /etc/apt/sources.list

add the following lines

deb http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu jaunty main
deb-src http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu jaunty main

Save and exit

Update the source list

sudo apt-get update

Install firefox 3.6 stable

sudo apt-get install firefox-3.6

---

For ubuntu 8.10 (Intrepid) Users

First you need to edit /etc/apt/sources.list

gksudo gedit /etc/apt/sources.list

add the following lines

deb http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu intrepid main
deb-src http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu intrepid main

Save and exit

Update the source list

sudo apt-get update

Install firefox 3.6 stable

sudo apt-get install firefox-3.6

---

For ubuntu 8.04 (Hardy) Users

First you need to edit /etc/apt/sources.list

gksudo gedit /etc/apt/sources.list

add the following lines

deb http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu hardy main
deb-src http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu hardy main

Save and exit

Update the source list

sudo apt-get update

Install firefox 3.6 stable

sudo apt-get install firefox-3.6

Updating Java and making it work

Add the JAVA PPA

deb http://ppa.launchpad.net/voronov84/andreyv/ubuntu karmic main

Go to the PPA homepage and grab the key if you need it;

https://launchpad.net/~voronov84/+archive/andreyv

Okay, now you can run your update manager and let it upgrade your JAVA install... It won't function properly due to an install bug but we'll fix than on short order.

---

Making Java work properly with Firefox 3.6

Now you need to navigate to the ~/.mozilla directory and make a folder called plugins (~/.mozilla/plugins/). Now using the terminal, run the command gksu nautilus to open a root file browser session. From there navigate to the following location:

/usr/lib/jvm/

Find the folder named java-6-sun/ and rename it to java-6-sun.bak/ (/usr/lib/jvm/java-6-sun.bak)

Now, in the same /usr/lib/jvm/ folder, find a sub folder named java-6-sun618/ or something similar, and rename it to java-6-sun/ (/usr/lib/jvm/java-6-sun/).

Now from a terminal screen run the following command:

sudo ln -s /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/

That should do it...

Roxie Is Awesome

Roxie has improved so much since my last post it can only be described as awesome.  She can play for hours on end without running out of steam.  I see no signs of hind-leg weakness.  Roxie has gained ALL of her weight back and eats like a little pig.  I would have to say that from all outward appearances, Roxie has made a full recovery and is enjoying life more now than in the past 2 years combined.  The only difference I have noticed in behavior is her STRONG desire to be held and hand fed occasionally.  Roxie wants lots of human contact and does not resist being a lap pet (unlike all other ferrets I've handled).  I love Roxie like no other pet I've ever had and every penny I've spent (thousands) towards her recovery was absolutely worth it.

More Roxie News

It's been 1 month and 1 day since I brought Roxie home from the hospital.  She's now eating on her own again and drinking from the water bottle.  What does this mean for me and my wife?  Well we don't have worry about being home and awake ever 4 hours around the clock.  Roxie had to be fed 16cc's of critical care food every 4 hours.  A lot of sleep was lost, and nearly late for work a few times.  I still feed her the critical care food before I go to work and as soon as I come home.  She eats her dry kibble when I'm not around so I don't have to worry so much.

Roxie has been out playing for the past hour and is much stronger.  She still tires or gets bored more quickly than in the past, but she's fattened up and I'm not so worried about losing her.  I think Roxie is definitely out of the woods now, but she will get special attention from me for the rest of her life.

Roxie is doing well...

After lots of hard work and around the clock care, Roxie is doing well.  She is still being syringe fed.  She's spoiled now and looks forward to the hand feeding and attention.  I keep her stuffed with high quality paste food (Carnivore Care) and Gerber Chicken w/Gravy.  She's gaining weight and much more alert.  She's no pup anymore but does enjoy getting out and playing every day.  Today she took her last dose of antibiotic and shows no signs of an ulcer anymore.  I hope she continues to improve and is around for several more New Year's days.  I love you Roxie.

Roxie is home, not doing so well.

Last night I brought Roxie home from the hospital.  Her blood sugar was lower than when she got there.  The prognosis isn't good and I'm not handling it well at all.  The doctor sent me home with some special food to push every 4 hours with a syringe.  I put her on my couch and started to prepare her food and she went into seizures.  It was very scary.  She barked and made noises I've never heard her make before.  I syringe fed her some pancake syrup and the seizure stopped, but she went limp and looked dead save for her breathing.  It was awful, I cried like a baby.  Joy wanted to take her to the vet and have her put down but I couldn't do it.  I pushed more syrup into here and in 10 minutes she was wide awake and running around like a brand new baby.

Now, I'm feeding her syrup along with her diet every 4 hours to prevent the seizures and it seems to work.  It's not a good long term plan but at least it makes her happier.  I have a sinking feeling in my gut that this won't work long term and I don't know what to do.  I'm kind of in a state of panic myself, I really love my Roxie and I can't face losing her right now.  I only pray that the prednisolone will start to inhibit her insulin production so that she will have a more stable blood sugar and a better life in her remaining days.  I'm so freaking sad about this that mere words can't even begin to describe my feeling of loss.  I love you Roxie...

Roxie is in the hospital.

Roxie is my number one Ferret.  She's really a HE as I recently found out.  Roxie has been very ill for the past month or so and It's tearing my heart out.  She was diagnosed with insulinoma (cancerous tumor on the pancreas) and a tumor on his adrenal gland. I took Roxie to the best veterinarian around and she removed the tumors from the pancreas, and removed 1 adrenal gland.  Then an implant (capsule with medication) was inserted between his shoulder blades to prevent any future tumors.

Everything was fine for a few days and Roxie seemed to be getting way better, then a couple of days ago she started sleeping all the time and didn't care to get out of her cage for play time anymore.  I sensed her blood sugar was low so I gave her some pancake syrup and after a few minutes he started acting normal.  20 minutes later however, he was weak and sleepy again.  Off to the vet I went.  The vet tested his sugar and reported it was 40.  Even worse than before the surgery. He had to stay and receive an I.V. with glucose and meds to coat his stomach.

The doctor said that he seems to have a stomach ulcer and perhaps he's not eating due to pain.  The lack of food intake could be the cause for the low sugar.  I hope this is the case.  it's also possible that the insulinoma is back but not likely according to the doctor.  I only hope and prey that Roxie is better tomorrow and the doctor tells me exactly how to care for him at home so that another trip to the hospital won't be needed.  Please pray for my Roxie... I love you Roxie...

Karmic Installed on 4 Machines

Well, I've installed Karmic on four of my machines and it's running well.  I don't like the way the new Grub2 looks by default and I'll be looking into customizing it's appearance.  If anyone has any tips (like how to remove the memtest86+ entries) please let me know.

I also just installed Flock browser 2.5.2 by hand.  I'm hoping the getdeb.net will soon start building packages for Karmic.  This blog post is being composed in Flock on Karmic.

Karmic Testing

It's been a long time since I posted here.  I'm testing Ubuntu 9.10 and so far I like it.  It's performance isn't that great on my old lappy with an ATI 9600.  Well 2D isn't that great but 3D is.  I'll get back soon with more information when I have time.  So far it looks like it's going to be a great release.

UPDATE:

By following my own guide for Jaunty.  I was able to put back most of the missing video performance.  You will find the instructions here.  I guess Karmic is here to stay.

Set up an FTP Server on Ubuntu

Installation

1. sudo apt-get install proftpd gproftpd. This will install all the necessary config files for proftp along with the GUI (gui being gproftpd)

2. Once install check to see if the server is running by using pgrep proftpd. If you do not see a PID than start it by typing /etc/init.d/proftpd start or status to see if again,  the process is running.

Configuring Server

1. Once installed proftp will be under a new category of programs called system tools. Go to system tool -> GA-ADMIN PROFTP

2. There are several tabs that gui provides in editing your FTP settings: they are server, users, transfers, discs, files, secuirty, and configuration

Server- name your server to your liking. Use your private IP address in the address field. Issuing an ifconfig at the cmd line will bring you your private IP.By default the server is set to an idle time of 120 seconds so adjust time if you wish to.

Users- this is where you will create all users that are allowed to your ftp site. You can create user accounts with anonymous access by un-checking the required password box. The users section is where you will designate directories/drives for remote users to access as well.

Transfers- Will show you files that where transfered between remote pc and server

Discs- Displays directories that are available to share along with how much space is currently available in those directories

Files-  shows statistics about what was downloaded by the user

Security- Gives a log file view of who was last logged  on the ftp server.

Configuration- If for whatever reason that your settings that you edited do not adjust you can change them here. Its easier to read by editing it here than terminal its a little cleaner and easier to see where and what you are editing

Home Router settings

Next, we are going to have to open up some ports on your router. Most newer routers they use port forwarding and with the older ones like my d-link router we create a new virtual server.

1. In your web browser go to the you gateway address which would be something like 192.168.0.1 or verify it by using ifconfig

2. The port that you want to open is port 21 or if you feel you will be vulnerable to attacks use 2121 or something along those lines

3. For the IP address of your sever it will be your private IP address

4. Save settings

Connecting to ftp server

1. Using a client such as filezilla which is free of charge or if you are an  intermediate-advance user use the command line. This is how we are going to connect to the ftp server

2. Find out Your public IP address using IPchicken.com. Once there it will display your public IP

3. You will use the public IP address to access you site along with a username, password, and port number. If everything is setup correctly you will be able to upload and download files. If you cannot go back and check that your settings are correct along with you private and public ip addresses

Non-Ubuntu Stuff...

I lost my job a couple of days ago. Being that I was a contracted worker I'm up the creek right now. Today I submitted my applications and resume to 22 different organizations. I have an interview tomorrow so any good luck or prayers you want to send this way would be appreciated. Hopefully my employment gap will be short and my new job better than the last. I'm not in the greatest of spirits right now so I'll close with this entry.

Adding the Medibuntu Repository

Below are the instructions to add the Medibuntu repository to your system's list of APT repositories. These are commands that should be run in the Terminal (Applications -> Accessories -> Terminal).

If you are new to Ubuntu, please see https://help.ubuntu.com/community/Repositories/Ubuntu for an overview of repositories.

Add Medibuntu to your sources.list, as well as its GPG key to your keyring. Make sure to use the correct sources.list that corresponds to your current distribution.

• Any Ubuntu Release and keyring:
  
  sudo wget http://www.medibuntu.org/sources.list.d/`lsb_release -cs`.list --output-document=/etc/apt/sources.list.d/medibuntu.list; sudo apt-get -q update; sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring; sudo apt-get -q update
  

  ---

• Ubuntu 9.04 "Jaunty Jackalope":
  
  sudo wget http://www.medibuntu.org/sources.list.d/jaunty.list --output-document=/etc/apt/sources.list.d/medibuntu.list
  

  ---

• Ubuntu 8.10 "Intrepid Ibex":
  
  sudo wget http://www.medibuntu.org/sources.list.d/intrepid.list --output-document=/etc/apt/sources.list.d/medibuntu.list
  

  ---

• Ubuntu 8.04 "Hardy Heron":
  
  sudo wget http://www.medibuntu.org/sources.list.d/hardy.list --output-document=/etc/apt/sources.list.d/medibuntu.list
  

  ---

• Ubuntu 7.10 "Gutsy Gibbon":
  
  sudo wget http://www.medibuntu.org/sources.list.d/gutsy.list --output-document=/etc/apt/sources.list.d/medibuntu.list
  

  ---

• Ubuntu 6.06 "Dapper Drake":
  
  sudo wget http://www.medibuntu.org/sources.list.d/dapper.list --output-document=/etc/apt/sources.list.d/medibuntu.list
  

  ---

Then, add the GPG Key:

sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

---

You may be asked to accept this package even though it cannot be authenticated. This is normal; typing "Yes" means you trust Medibuntu.

Install a different media player (optional)

The default media player (totem) is good, but I like vlc media player better, especially for watching a dvd.

In a terminal type:

sudo apt-get install vlc

If you are looking for a better audio player, I suggest either exaile or bmpx.

You now have 99% of the codecs in the world installed on your system.

Looking for real player? click me.

Ubuntu Juanty Jackalope vs. ATI Radeon Mobility 9600

Okay - After lots of begging for help on the Ubuntu Forums, I found a workable configuration for my ATI graphics card in my old eMachines M6809 laptop. With out these settings in my /etc/X11/xorg.conf file it was totally unsatisfactory. Now however, it's near full speed as compared to Hardy and the infamous MS WinXP Pro.  Here are the settings I'm now using.

Section "Device"

Identifier     "Configured Video Device"

Option         "AccelDFS"                               "on"
Option         "AccelMethod"                         "XAA"
Option         "MigrationHeuristic"                "smart" # "greedy" works well also
Option         "EnablePageFlip"                      "on"
Option         "EnableDepthMoves"                "on"
Option         "ColorTiling"                            "on"

HISTORY & CREDITS:

• This project was born after Charles Jackson's (crjackson) request for a program that time-limits user accounts:
  Ubuntu Forums. You can also find a progression of the history posted at the Bucknasty. blog.

• This is a complete re-write in python and vast improvement from the original timekpr bash script:
  Waggledance.

• Even Nedberg initially began to improve the original bash script from Chris Jackson. Savvas Radević packaged it and soon began co-development.

• Special thanks go to Charles Jackson (crjackson), who has contributed a lot by suggesting, brainstorming useful features, writing the initial blueprint, and
  being the primary tester.

• We would also like to thank all the people posting to that topic in ubuntu forums for their comments.

---

Additional Information

Developers Even Nedberg and Savvas Radević (or .nedberg and forger) of the Ubuntu forums have rewritten the package using python as opposed to the bash shell script of it's previous form. timekpr now has a full featured interface with the ability to change and grow as needed.

I have requested an additional feature of a black-out setting that would let you slice a chunk of time right out of the normally allowable login hours. This would be for designated home work time, or other required activities. Please bookmark this page for future updates.

- Charles

Ubuntu 9.04 - Jaunty Jackalope Testing

I've been testing the soon to be released version of Ubuntu 9.04 beta. I am very impressed with it's performance and stability so far. Only time will tell however if it's going to be suitable for my laptop with an Intel GMA X3100.  Intel video adapters have a poor history with Linux and I couldn't run Intrepid due to poor video performance.  Hardy runs fine however. The performance issues stem from the latest/greatest xorg system. The drivers just haven't caught up yet.  So far the beta on LiveCD runs great though, and I have high expectations.
