Fedora Core 9 provides a java 1.6 plugin for the FireFox. However, I have found that it doesn’t work for some of the web sites, in particular, my Internet banking and fansub.tv. This post describes what I have done to get my Java applets to work in FireFox.

  1. Download JDK 6 update 6 (bin version, not the rpm) from java.sun.com. I believe there is also a similar plugin in Java SE 6 runtime as well.
  2. Run the jdk-6u6-linux-i586.bin file. If you get a permission error, try “sh jdk-6u6-linux-i586.bin file” on your terminal. Simply follow the instructions and complete the unpacking process. You should have a new folder called jdk1.6.0_06.
  3. Move this folder to /usr/local. You may need to sign in as root to do this.
  4. In your home folder, create a symbolic link to the Java plugin like this: “ln -s /usr/local/jdk1.6.0_06/jre/plugin/i386/ns7/libjavaplugin_oji.so ~/.mozilla/plugins/libjavaplugin_oji.so
  5. Remove the openJDK web browser plugin that is currently installed on your system: “rpm -e java-1.6.0-openjdk-plugin
  6. Restart your FireFox. On the address bar, type “about:plugins“. You should see a section called Java(TM) Plug-in 1.6.0_06-b02 with the corresponding Java MIME-Type that have associated with this plugin. Your applets should work now.

My home gateway machine is a 5-year old Intel P4 2.4GHz machine running FC8. This machine has undergone a few Fedora upgrades from FC5 to FC7 and then to FC8. The hard disks have been replaced 3 times, and the partitions have been messed up because the hard disk replacements are often larger in capacity than the burn outs.

The upgrade this time is a clean installation of Fedora Core 9 with a couple of new hardware–a new LG DVD superwriter, Adaptec 1420SA SATA-II RAID controller and 2 x WD Caviar SE16 640GB hard disks. There were minor glitches during the installation, but they were resolved through the abundant information available on the Internet.

This blog post documents the steps required to setup email hosting for multiple domains on a Fedora Core 7 box. At the end of the setup exercise, you will have a email hosting system that uses

  • MySQL for account storage information
  • Postfix as mail transfer agent (MTA) with SMTP/SSL and STARTTLS capability
  • Dovecot for POP3 and IMAP (including SSL for security)
  • PostfixAdmin for account management
  • Lighttpd as a light-weight HTTP daemon service for PostfixAdmin
  • Postgrey as a deterrence against spams.

If you are familiar with system administration and using yum, you should be able to complete this within 30 minutes.
