WordPress and special characters

Today when I was adding an article, I was getting really upset with WordPress, I just wanted to add some simple characters and have it printed AS IS.

When working with WordPress and using special characters like a redirection symbol ” > ”  or something enclosed in it’s on tag  like “<dev>” it will get hosed while editing in “HTML” mode. You could insert syntax to stop it from doing that, but it’s much easier to add a post with such things in “Visual” mode first. Then switch over to “HTML” mode if any other special tags are needed.

SWAT in 60 seconds

Q. What is SWAT?
A. It’s the “Samba Web Administration Tool”

Q. What can I use it for?
A. (shrug )Maybe to quickly setup a SAMBA server etc. 😉 from following my previous howto.
A2. It does have some good info even if you don’t use it for your SMB configuration.

We all know it’s best to use the command line interface (CLI) when learning something,
and most GUI tools don’t give you all the options anyway. However, it’s nice to have a GUI tool when you’re in a rush or you just want to try something new without digging for hours.

This article assumes you have already installed SAMBA.  See my previous article if you haven’t.

According to the SWAT docs, it will overwrite you current SMB.conf,
so you may want to backup your current one first.

# Backup the current smb.conf
sudo cp --preserve=context /etc/samba/smb.conf /etc/samba/smb.conf.pre-swat

# Install the SWAT tool
sudo yum install -y samba-swat

# Set the service to launch and start it up
sudo vi /etc/xinetd.d/swat (change the disable from yes to no)
sudo /sbin/service xinetd restart

# Browse to

SAMBA – Home Directory Shares Made Easy

Q. What is SAMBA?
A. “Samba is a Free Open Source Software suite that provides seamless file and print services to SMB/CIFS clients.”

Q. Where is SAMBA’s home?

Q. Why did you bother writing this?
A. Several reasons, mostly to help myself and others.

Note: You may want to copy/paste this into a txt file for easier reading.

This “entry level” guide will show you how to configure SAMBA in order to let users
browse their home folders under Linux via Windows.

Please note: I write these guides under RHEL/CentOS. However, they should work under any distribution. You still may need to tweak things a little. ;0)

I’m also assuming you have sudo rights. You shouldn’t work from root!

If you’ve installed the default settings for SELinux, it will be in “Enforcing” mode.

# To check your SELinux status. (1 = Enforcing, 0 = Permissive)


# If you wish to change the state from Enforcing to Permissive temporarily


If you wish to change it permanently between reboots, alter the /etc/selinux/config file to say Permissive
If you wish to keep using SELinux, I’ll provide the extra step to work with this guide,
other wise just ignore the SELinux “setsebool” command.

NOTE: Review the /etc/samba/smb.conf for addtional SELinux settings.
# Install the SAMBA server.


# Add a user for testing the SMB/CIFS Shared Home directory.


# Configure the user “sambatest” smb password.


# Backup the /etc/samba/smb.conf file prior to any changes.
# Edit the smb.conf file and set your “workgroup” / “netbios name” if needed.


workgroup = workgroup (this is Windows default group)
netbios name = CENTOS (don’t forget to uncomment this line)

# Set the SMB daemon to start on boot up. (for levels 2345)


# Start the SAMBA daemon.


# OPTIONAL (if using SELinux)


# You’ll want to edit your iptables/firewall rules to allow connections.
# I would recommend locking this down to local network hosts etc.
# I’ll assume your trusted hosts are on a network.

-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp -s --dport 137 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp -s --dport 138 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp -s --dport 139 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp -s --dport 445 -j ACCEPT

# From Windows, browse your “workgroup” network and you should now see “CENTOS”
# Simply log in with the account/smbpasswd you’ve created.

Apple has new goodies……sort of

I’ve been waiting a LONG time on the new Mac-Mini refreshes, and I have to say I was surprised at the new versions. They’ve got a little kick to them this go around. However, if you bump the RAM up to at least 2GB and add the 3year warranty and a new keyboard, you are sitting at about $900.00

If you don’t care about the warranty and don’t need the keyboard, you can still get the 2GB of RAM and keep it down to $649.00.

Also, they released new Mac Pros and iMacs. I have to say I was impressed, that is, until I read a little more. Apple and I have a strange history: I love to support them and I love OSX. However, they always seem to just MISS my cup of tea, and I always think…”Well, I’ll wait for the next round”.

Let me explain. As you know (or don’t) Apple has pretty much switched from ATI to Intel to Nvidia for graphics. However, even with the brand new models, the BEST you can get (Nvidia wise) is a  GeForce GT 130. If you are thinking “130…what the hell is that?”, read on.

Basically, as most of us know, the “best of the best” in the Nvidia world is the “GTX 2xx” series, and prior to that, it was the 9800 Series. Well, Nvidia has renamed their chip line on the 9600/9500 line to…you guessed it! “GT1xx” !!!!!!

If I’m right, it seems the GT 120 is a renamed 9500 and the GT130 is a renamed 9600! I can’t believe that even on the HIGH end Mac Pro, they DON’T offer at least ONE version of a GT280! However, they do seem to offer a ATI 48xx series, which is good, but as I said I LOVE Nvidia.

Now on the other hand, I’m always looking at this situation from the stand point of “what if I want to GAME and run everything with nice resolutions and AA etc”, and as most of us know…if you want to game with the big boys, just build a PC. Well, that still seems to be the case.

On the brighter side of things, these new Macs truly have some wonderful configurations and will be very good machines, especially for those people that just want to do everything but the high end gaming.

My advice:

If you’ve never had a Mac, and don’t care about gaming at all, but need a complete computer (monitor and all) I would go for the 1499.00 iMac, as it has a 24inch screen.
If you think you’ll game from time to time, I would go for the 1799.00 iMac and possibly upgrade the video card to the GT 130 or the ATI card.
If you’ve never owned a Mac and are happy with your current computer, but are curious about OSX and would like to just use the monitor, mouse, keyboard etc. that you have, then go for the entry Mac Mini and upgrade the RAM to at LEAST 2GB.

If you’re a hard core gamer and want to keep up with the latest games etc…just keep building PCs or check out the Dell XPS 630 for a great entry gaming rig that can upgraded as needed.
