Fixing Flash Issues in Ubuntu Karmic 9.10

by manojgumber

[tweetmeme service=”bit.ly” source=”LeisureHoursWP” ]

Flash does not work fine by default in Ubuntu Karmic and creates a lot of problems. This can be fixed by installing official flash from Adobe.com

  • First of all , uninstall any existing flash packages. Otherwise they  will clash with this package. You might have gnash / swfdec / adobe plugins installed earlier. So remove them before trying this.

    $ sudo apt-get remove flashplugin-installer flashplugin-nonfree mozilla-plugin-gnash swfdec-mozilla

  • Go to http://get.adobe.com/flashplayer/ . It has a menu which asks version to download . Select ‘ tar.gz  for Linux ‘ package  and download.
  • Extract the files of this tar package

    $ tar -xvf install_flash_player_10_linux.tar.gz

  • It contains a file libflashplayer.so.
    Copy this file to /usr/lib/mozilla/plugins (Note – firefox should be closed while doing this )

    $ sudo cp libflashplayer.so /usr/lib/mozilla/plugins/

  • Start firefox and type ‘ about:plugins ‘ in address bar to check if the flash plugin is installed properly.

    It will show an entry for

Shockwave Flash

File name: libflashplayer.so
Shockwave Flash 10.0 r45
Thats all. Flash is working fine on karmic now.

Still this is not a problem at all. Even if you want that partition numbers should be in their order in hard disk , this can be done.

Here fdisk utility comes to rescue.

Encrypt & Secure Your Files Using vi Editor

by manojgumber

[tweetmeme service=”bit.ly” source=”LeisureHoursWP” ]

Do you know that you can encrypt your source code files and other text files using vi editor? Isn’t vi editor wonderful.

It is very simple. While creating new file which you intend to encrypt

leisurehours@wordpress-laptop : ~ $ vi -x file1.txt

To encrypt an existing file , open it with vi using -x option

leisurehours@wordpress-laptop : ~ $ vi -x file1.txt

vi editor will now ask for password twice. Whenever you will open the file again with vi editor, it will ask for password to decrypt the file. When opened using other editors , file will show only garbage text.

convenient command and you do not have to remember any parameters as

tools like useradd, groupadd and usermod programs,
by default choos‐

ing Debian policy conformant UID and GID
values, creating a home

directory with skeletal configuration, running a
custom script, and

other features.
