Remove audacity (#yum remove audacity), install audacity-freeworld (#yum install audacity-freeworld ). That’s it. You might have to enable RPMFusion.
- Install encfs
- do $mkdir ~/Dropbox/Secure ; mkdir ~/DropboxSecure
- do $ encfs ~/Dropbox/Secure ~/DropboxSecure
- I chose paranoia mode. This will use the settings below.
- Enter a secure password and there you go.
You now have a folder ‘DropboxSecure’, in which you can store your sensitive data. It will save this in ~/Dropbox/Secure/ .
You can unmount this via $ sudo umount /home/karlo/DropboxSecure #needs to be done using sudo. I guess this is a bug. After umounting, you will notice the directory DropboxSecure is still there, but empty.
Mount again by using step 3 and entering your password.
Paranoia settings:
Filesystem cipher: “ssl/aes”, version 3:0:2
Filename encoding: “nameio/block”, version 3:0:1
Key Size: 256 bits
Block Size: 1024 bytes, including 8 byte MAC header
Each file contains 8 byte header with unique IV data.
Filenames encoded using IV chaining mode.
File data IV is chained to filename IV.
File holes passed through to ciphertext.

Easier than my previous post, use this plugin for wordpress.
I generated SSL certs using this guide. Then I set up dovecot and postfix. View my dovecot conf here and my psotfix main.cf here.
You can use this to configure your own working SSL mail. Remember to install: dovecot, dovecot-imap and postfix.
On your devices, use ports 143/993 (incomping) and 587 (outgoing).
Please note my main.cf file also includes config for mailman.

Getting this?
$ sudo service dovecot restart
* Restarting IMAP/POP3 mail server dovecot
Error: mail_executable: Can’t use /usr/lib/dovecot/imap: No such file or directory
Fatal: Invalid configuration in /etc/dovecot/dovecot.conf
…fail!
install dovecot-imap 
- Give your wordpress dir the right permissions: sudo chmod -R 775 wp-dir ; sudo chown -R username:www-data
- Add this in wp-config.php: define(‘FS_METHOD’,'direct’);
You can now update via ‘update now’.
I used the following script to test brute-force protection:
#!/usr/bin/php
<?php
for( $i=0; $i<99; $i++ ){
echo “Will try [$i] now. \n”;
$mbox = imap_open(“{mail.mailserver.com:143/imap/novalidate-cert}INBOX”,”user_test_$i”,”foobar”,0,0);
}
?>
Edit: You will need php-cli and php-imap
Found this gem on an other blog:
Deprecated Linux networking commands and their replacements
I mostly use $ifconfig. Let’s try `$ ip a` from now on

Recently I got the error:
GConf Error: Configuration server couldn’t be contacted: D-BUS error: Method ” GetDefaultDatabase” with signature “” on interface “org.gnome.GConf.Server” doesn’t exist.
I got this while trying to start Evolution (mail software).
Solution is simply rebooting. I forgot to reboot after my Fedora 15 to Fedora 16 upgrade
Getting this:
$ java drs.jar
