Installing Samba

Running on CentOS 4.1 the following steps were use to install Samba.

Install RPM’s
$ rpm -ivh samba-3.0.10-1.4E.i386.rpm
$ rpm -ivh samba-swat-3.0.10-1.4E.i386.rpm

Start Processes
$ /etc/rc.d/init.d/smb start

Check Processes
$ ps -ef | grep smb
root 21243 1 0 10:19 ? 00:00:00 smbd -D
root 21244 21243 0 10:19 ? 00:00:00 smbd -D
$ ps -ef | grep nmb
root 21248 1 0 10:19 ? 00:00:00 nmbd -D

Enable on System Reboot
$ chkconfig smb on
$ chkconfig –list smb

Configure SWAT (web interface to administer samba)
$ vi /etc/xinetd.d/swat

# default: off
# description: SWAT is the Samba Web Admin Tool. Use swat 
#              to configure your Samba server. To use SWAT, 
#              connect to port 901 with your favorite web browser.
service swat
{
        port            = 901
        socket_type     = stream
        wait            = no
#       only_from       = 127.0.0.1
        user            = root
        server          = /usr/sbin/swat
        log_on_failure  += USERID
        disable         = no
}

$ killall -SIGHUP xinetd
$ tail /var/log/messages

Sep 13 10:17:18 omega xinetd[2160]: Starting reconfiguration
Sep 13 10:17:18 omega xinetd[2160]: Swapping defaults
Sep 13 10:17:18 omega xinetd[2160]: Reconfigured: new=1 old=0 dropped=0 (services)

Verify Settings

Using the installed SWAT, simply point the browser to http://111.111.111.111:901/

Htaccess is root and the system root password

Configuring Samba, well that’s another story.

Producing Skewness statistics with SQL

Skewness measures the asymmetry of a distribution. A perfectly symmetric distribution has a skewness of zero. A positive skew (right-skewed) means the tail extends to the right — a small number of high values pull the mean above the median.

Exploring the vsql-ai extension

The vsql-ai extension adds AI prompt capabilities and text embeddings directly in SQL queries, with support for Anthropic Claude , Google Gemini , OpenAI ChatGPT , or a local LLM such as Ollama .

Producing Chi-Squared statistics with SQL

The Chi-Squared test is one of the most widely used statistical tests for categorical data. It comes in two flavors: the goodness-of-fit test asks whether an observed frequency distribution matches an expected one, while the test of independence asks whether two categorical variables are associated with each other.
