ps -ef | grep httpd

Your output may differ slightly based on your operating system, but it should look something like:

    0    48     1   0  7:22AM ??         0:00.44 /usr/sbin/httpd -D FOREGROUND -D WEBSHARING_ON
   70   165    48   0  7:22AM ??         0:00.01 /usr/sbin/httpd -D FOREGROUND -D WEBSHARING_ON
  501  1247  1219   0  7:50AM ttys001    0:00.00 grep httpd

On certain operating systems, it may not return anything. In that case, try command:

ps -ef | grep apache2

If you don’t receive any results from both commands, you may not be running Apache/httpd. Nonetheless, you want to pay close attention to /usr/sbin/httpd. That is the location to your binary file. Run the following command to obtain the location to your configuration file:

/usr/sbin/httpd -V | grep SERVER_CONFIG_FILE

You’ll see something like the following, which will designate the location for your httpd.conf file.

 -D SERVER_CONFIG_FILE="/private/etc/apache2/httpd.conf"

After you have applied your respective iptables rules, you may wish to check on your iptables rules before you save them. Use the following command to list all the current rules:

iptables -L

Use this command to save the iptables rules (the following command is the actual command to save the rules so they are applied on boot)

/sbin/service iptables save

The following command would allow you to double check that your rules have been saved. It is similar to iptables -L, but also different. The previous command shows all the rules that are currently in effect, but many of those rules will not be applied after your system has been restarted. The following command will show all the rules that are currently in effect and have been written to disk, meaning they will apply even after a reboot.

cat /etc/sysconfig/iptables

<?php
$delimiter = ',';

$db = new mysqli('localhost', 'username', 'password', 'database');

if (($handle = fopen("import.csv", "r")) !== FALSE) {
	while (($data = fgetcsv($handle, 1000, $delimiter)) !== FALSE) {
		foreach($data as $i => $content) {
			$data[$i] = $db->real_escape_string($content);
		}
		$db->query("INSERT INTO mytable VALUES('" . implode("','", $data) . "');");
	}
	fclose($handle);
}

?>

A few things to keep in mind:

• Make sure you change the MySQL login information to your own login information
• Make sure you change the table name, in this case, mytable, to your own table name.
• For your CSV (comma separated values) file, the delimiter may not necessarily be a comma. Change the $delimiter variable to the one-character delimiter separating the different fields.
• This does NOT automatically create a table. You have to manually do that.
• Every row would be inserted, so you should manually remove the first row if it is just the column names.

yum install ntsysv

After you have installed it, run the ntsysv command.

ntsysv

You’ll be presented with a window that has a combination of red, blue, and gray.

Use the up/down arrow to navigate the list. Use the spacebar to check/uncheck a service. Use your tab to navigate to ‘Ok’ and ‘Cancel’. This part is mostly self explanatory.

rm -rf -file

Except that doesn’t work. My CentOS complained to me with the following message (though not all operating systems may supply this, so this is mainly for those whose OS does not supply this tip):

rm: invalid option -- 'l'
Try `rm ./-file' to remove the file `-file'.
Try `rm --help' for more information.

The suggested tip here works well. Simply running the following command should delete the “-file” file.

rm -rf ./-file

Keep in mind this limitation does not apply only to the rm command, but a large number of commands including touch and others. It is the most annoying for the rm command, since you are trying to remove the file. For these other commands, you would also have to prepend the file name with a ./ in order for this to work.

Take a look at the two images below of what my screen normally looks like, and what my screen looks like when the colors are inverted

Do keep in mind if you take any screenshots in the ‘inverted color’ mode, the screenshot will not come out with inverted colors. If you would like to have inverted colored screenshots, you must manually invert the image in an image editing program.

yum install gcc make libXext-devel libSM-devel libICE-devel zlib-devel libXfixes-devel libXdamage-devel libvorbis-devel libtheora-devel

Because CentOS does not official an RPM for recordmydesktop, we will have to install it from source. We will download a tar of the source code, untar the source, and remove the tar file:

wget http://downloads.sourceforge.net/project/recordmydesktop/recordmydesktop/0.3.8.1/recordmydesktop-0.3.8.1.tar.gz
tar xf recordmydesktop-0.3.8.1.tar.gz
rm -rf recordmydesktop-0.3.8.1.tar.gz

Now, let’s go into the folder and install Recordmydesktop.

cd recordmydesktop-0.3.8.1
./configure
make
make install

If you did not set a custom prefix, running /usr/bin/recordmydesktop should begin recording your desktop! Use the following command (just as with most commands) to view the options available:

recordmydesktop --help

To begin with, make sure you have the older version of Firefox/Thunderbird installed. This is necessary, as we are going to use their launch scripts as a template to create the launch scripts for the newer version.

To shorten things up, I will refer to Thunderbird as TB, and Firefox as FF. For the most part, I will refer to TB instead of both TB and FF. All you have to do is change where I write ‘thunderbird’ to ‘firefox’ and it will most likely work. To begin with, you want to download the latest version of Thunderbird or Firefox.

• 32 bit TB:

  wget 'http://releases.mozilla.org/pub/mozilla.org/thunderbird/releases/10.0-real/linux-i686/en-US/thunderbird-10.0.tar.bz2'

• 64 bit TB:

  wget 'http://releases.mozilla.org/pub/mozilla.org/thunderbird/releases/10.0-real/linux-x86_64/en-US/thunderbird-10.0.tar.bz2'

• 32 bit FF:

  wget 'http://releases.mozilla.org/pub/mozilla.org/firefox/releases/10.0/linux-i686/en-US/firefox-10.0.tar.bz2'

• 64 bit FF:

  wget 'http://releases.mozilla.org/pub/mozilla.org/firefox/releases/10.0/linux-i686/en-US/firefox-10.0.tar.bz2'

Untar and unzip the file you just downloaded (as said before, name may vary with the product you are installing). Afterwards, delete the tar file, which is no longer necessary.

tar xf thunderbird-10.0.tar.bz2
rm -rf thunderbird-10.0.tar.bz2

The simplest way is to delete the current TB/FF install, and move the newly downloaded files to the old directory. This command will vary for 32 and 64 bit systems. IMPORTANT: For Firefox, change the number 3.1 to 3.6 for both architectures. As for the commands, for 32 bit:

rm -rf /usr/lib/thunderbird-3.1/*
mv thunderbird/* /usr/lib/thunderbird-3.1/

For 64 bit systems:

rm -rf /usr/lib64/thunderbird-3.1/*
mv thunderbird/* /usr/lib64/thunderbird-3.1/

Congratulations! You are more or less done. Now, you may want to get rid of the empty FF/TB folder by running the command:

rm -rf thunderbird

That’s pretty much all. Running command ‘thunderbird’ or going to ‘Applications -> Internet -> Thunderbird Email’ will launch the newly installed version!

Beyond TB/FF 10, the ‘automatic upgrade’ feature should kick in. As you can see in the two screenshots above, TB and FF will automatically look for new versions, and will automatically upgrade when they exist. This way, you can run much newer versions than those found in the CentOS/RHEL repo.

Go under the Advanced tab, and under the Network tab. From there, click on Settings.

Choose Manual proxy configuration. Leave everything empty except the SOCKS Host and Port. The SOCKS host and port should be the respective host and port.
