yum -y install libXScrnSaver.i586 libXss qt.i586 qt-x11.i586

Here’s what I have to do to get Fedora 11 running like I want it:

1. Fix the DNS lookup bug. On all the machines I administer, this manifests itself as massive dns lookup failures, with the effect that although you can ping an address, you don’t have any internet access (no web browser, no yum…).  This answers the question:  I have an internet connection, but I can’t use the web, WTF?
2. Access to fusion
3. Add MP3 support/get Amarok working.
4. Get Flash working (people need their youtube).
5. Graphics acceleration
6. Make FAT partitions writeable by users, and add ntfs support.
7. Disable physical file folders.
8. Enable Ctl-Alt-Backspace

What’s less fantastic, is when I want to cut and paste the html output here to my WordPress blog.  Unfortunately org-mode puts in linefeeds between paragraph elements, and for some reason wordpress maintains these, resulting in incorrect word wrapping.  So I want a way to remove the the linefeeds between paragraph elements.

This was just a little bit beyond my capabilities with SED, and I’m often telling myself self, you should really learn how to use sed and regex terms better . So I thought bugger it, let’s figure out how to do this. So I whipped out the excellent book “sed&awk” from O’Reilly.

As someone who has only used sed for banal substitutions, I had to learn the following:

• “:whatever” can be used to create a label.  There are two commands that allow you to utilize these lables: “b” creates a branch, while “t” jumps to a label if a successful substitution has been made on the currently addressed line.
• “N” is needed to join two lines, since sed normally works on a one-line-at-a-time fashion.

With these two tidbits, and a basic understanding of how sed operates, we can construct the desired script.

:top
/<p>/
{:loop
  N
  s/\n/ /
  /<\/p>/{P;D;btop}
  bloop}

In one line the command looks like this:

 sed ':top;/<p>/{:loop;N;s/\n/ /;/<\/p>/{P;D;btop};bloop}'

If you’re like me, it’s not immediately clear what’s going on here, so let’s break it down:

• First we create a label with “:top”.
• “/<p>/” tells sed to look for the paragraph block tag.  The next ‘line’ of the script will be called after this tag is found.
• The curly braces “{}” group a set of commands, so upon encountering the paragraph tag, it executes the contents of these brackets.   In the brackets:
  • Create a new label “:loop”.
  • “N” creates a multiline pattern space by reading the next line of input, and appending it to the contents of the pattern space.
  • “s/\n/ /”: substitute a space for the line feed.
  • “/<\/p>/{P;D;btop}”:  If sed encounters an end of paragraph tag, it executes “P;D;btop”, which (P) prints the contents of the multiline pattern space, (D) deletes it, and (btop) creates a branch(b) and goes to the label(top).   It’s a little like “if (<p>) goto top”.
  • “bloop” (b) branch and goto label(loop).

So as long as no closing tag (</p>) is found, we have a loop that keeps adding new lines to the multiline pattern buffer, and substituting spaces for linefeeds.  When the closing tag (</p>) is found, the loop goes back up to the “top” label.  That loop makes sure all of the  paragraph sections get handled.

So that’s it.  If anyone knows a more elegant solution to this, I’d be glad to here about it.

• makes my background color a little less harsh.
• enables syntax highlighting by default.
• makes the selected region highlighted (this behavior will be default in the next version of emacs, but I’m using 22.x at the moment).
• modify the tab width to 3.
• enable org mode
• make line numbering available (this is sometimes useful).

I’ll be keeping this up to date as my make changes…

1. Generate a public key.  Logon to the host want to connect from:

    #ssh-keygen -t dsa

   This generates a key pair (of type dsa), both of which are located in the .ssh directory.  The files will be id_dsa and id_dsa.pub.  The latter file is the public key, and the former the private key.  By copying the public key to the .ssh/, we provide ssh with an alternate means of confirming our access rights.  Rather than prompt for a password, it checks that the private key (client side) matches that of the server (public key).

2. Append the generated key to the servers .ssh/authorized_keys file.  The simplest way is:

   ssh-copy-id -i ~/.ssh/id_dsa user_name@remote_host.org

That’s it.  Now you should be able to scp, ssh, or git (via ssh) to that machine without entering a password. You may have to enter the private key (the passphrase you provided when generating your key pairs) the first time you use ssh from the pc (this is the default behaviour on Fedora).
If you run into problems, this is discussed in more detail here.

Fedora is great in many ways, and I stick with it because I’m pretty happy with it, philosophically and technically, but you often have to put a little work on it, particularly if you’re a 64-bit user and you to use a good graphics card.  Anyway, I thought it would be handy for me to have a checklist on the web, so I don’t forget anything the next time.  This is just a collection of solutions I’ve dug up somewhere else, but it might still be useful for others.

These are the things I have to do to get Fedora working acceptably:

1. Fix the DNS lookup bug.  On all the machines I administer, this causes massive dns lookup failuers, with the effect that although you can ping an address, you don’t have any internet access (no web browser, no yum…).Add access to the fusion repository.Install various extra software.
2. Access to fusion
3. Add MP3 support/get Amarok working.
4. Get Flash working (people need their youtube).
5. Nvidia support.
6. Make FAT partitions writeable by users, and add ntfs support.
7. Disable physical file folders.
8. Enable automounting of external drives (usb sticks for example).

1. Fix the DNS bug

Apparently there is a known bug, which mucks up the domain name lookup with certain ISP’s, of which bluewin (my ISP) is one.   In the bug description the complaint is that you get unreliable name lookups, but in the case of bluewin, you get no successful lookups.  A workaround is described here.  All you have to do is:

1. Make sure that dnsmasq is installed.
2. find out the network interfaces the machine has ( route -n )
3. create a file called /etc/dhclient/< your network intervace name here >.conf consisting of the line
4. ‘ prepend domain-name-servers 127.0.0.1; ‘
5. Start dnsmasq (‘service dnsmasq start’).
6. tell dnsmasq to start every time the computer does (‘chkconfig dnsmasq on’)
7. restart the network connection (‘service NetworkManager restart’)
8. Add ntfs write support.

2. Access to fusion:

Fusion is  a merge of the largest existing addon repos, and means to be the extra repo for fedora, including (separate) free and non-free packages that Fedora is not able to ship of license or export regulations (see comment by ingvar).

# rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

3. Add mp3 support

I use Amarok as my primary music application.  Fedora comes with Amarok 2, which I am still evaluating, but I found Amarok 1 vastly superior to the alternatives, so I’m hoping Amarok continues to be awesome.  I actually hate switching apps.  Unfortunately, just installing Amarok gives me no sound.  After running Amarok in a console and checking out the output, I tried:

# yum groupinstall phonon*

which did the trick.  I  Finally, to support mp3′s, you can do:

# yum groupinstall sound-and-video

4. Get Flash (i.e. Youtube) working

This solution  comes from here.   I quote verbatim:

• rpm -e nspluginwrapper.i386 flash-plugin (if you have installed them)
• cd /usr/lib64/mozilla/plugins/ (this is where your Firefox plugins are)
• wget http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.d20.7.linux-x86_64.so.tar.gz (to download the Flash plugin)
• tar -xvzf libflashplayer-10.0.d20.7.linux-x86_64.so.tar.gz (to extract the plugin)
• restart firefox.

At this point you tube shows up fine.

5.  Enable your 3d hardware acceleration

In my case, I just run ‘yum install kmod-nvidia’ and restart X.  If you have a radeon card, I suppose the solution is the obvious one.

6.  Make the fat drive writeable, and add NTFS write support, so people can easily work with Windows.

For any fat partition, change the umask in fstab to 000.  For NTFS support, ‘yum install ntfs-config.noarch’.

7. Disable “physical” file folders.

This is the annoying behavior, default in gnome, that opens a new window for every folder that you open.  Get rid of it by double clicking on a folder, and in the resulting window open edit->preferences->Behavior, and check the box for  “Always open in browser windows”.  There is a scriptable way to do this, so if someone wants to tell me, please do.

8.  Allow automounting of usb drives etc.

I really hope this is an error, but it’s possible it’s a security precaution.  By default, if you plug in a usb stick or some such storage device, you won’t see it automatically on your desktop.  This is because automounting isn’t allowed by default.  You can change this by going to System->Preferences->Authorizations and click on hal->storage->Mount file systems from removable drives.  Click on the Edit box in the Implicit Authorizations sections, and change Anyone to yes.

9.  Scripts:

I have a script which installs a lot of the stuff I typically want but is not included in Fedora by default.  These include mplayer, par2, rar,  amarok(music listening), emacs, development tools, etc.  If you want it, the script is here.
