Here is the brief description about addon domains, parked domains and subdomains

Addon domains

An addon domain allows to add a new domain name in your account. The addon domain’s files will be stored in a subdirectory of your public_html folder. You can add multiple domains if allowed by your host in single account with the help of addon domains. They do not have separate cPanel but you can add email addresses, ftp accounts etc.. like main domain from your cPanel.

Parked domains

Parked domains do not have any content. They are use to show same webpages of the main domain. Generally thy used for seo purposes.

Subdomains

You can define subdomain as subsection of your main website. You can add multipl subdomains under your main subdomains. For example if you wsih to add blog on your site you can add subdomain blog.yoursitename.

It takes some time to propagate subdomain’s dns records as they do not have their special dns zone file on server.

When your IP got blocked in cphulk database you can not remove it from WHM as cPanel has not offer this feature yet. You will have to flush cphulk database for this but this will remove other IPs too that is not recommended as far as security is concerned.

In order to remove particular IP from cphulk bruteforce database you will have to access database and has to remove that IP.

You can do this by two methods

1)Access database through shell
2)Access database through phpmyadmin

I will explain you first method as second one is relatively easy.

Access server with root user. Type in mysql as you will login to mysql shell. Now to connect database cphulkd type in

mysql> use cphulkd;

You will now connect to database cphulkd. Now type in sql query
just to confirm if your IP is really blocked there.

mysql> SELECT * FROM `brutes` WHERE `IP`=’x.x.x.x’;

If you are able to see your IP in brutes then simply remove it by

mysql> DELETE FROM `brutes` WHERE `IP`=’x.x.x.x’;

Once it done quit the mysql by typing

mysql> quit

In this way your IP will be removed from brute force and you will enjoy cPanel browsing.

The default instance of the Microsoft SQL Server Database Engine listens on TCP port 1433. Attackers attack on port 1433 to hack sql server and make it highly unstable. Because of this many hosting providers change sql port other than 1433.

Here are quick steps to change mssql port.

Login to your server through RDP.
Open SQL Server Configuration Manager.

In SQL Server Configuration Manager, expand SQL Server 2008 Network Configuration, expand Protocols for ,
and then double-click TCP/IP.

In the TCP/IP Properties dialog box, on the IP Addresses tab, you will notice multiple IP addresses.
One of these are for the IP address of the loopback adapter, 127.0.0.1. Additional IP addresses appear for each IP Address on the computer. Right-click each address, and then click Properties to identify the IP address that you wish to configure.

If the TCP Dynamic Ports dialog box contains 0, indicating the Database Engine is listening on dynamic ports, delete the 0.

In the IPn Properties area box, in the TCP Port box, type the port number you wish this IP address to listen on, and then click OK.

In the console pane, click SQL Server 2008 Services.

Now you need to open the custome port in windows firewall. For this please refer to http://support.microsoft.com/kb/968872
Once it done in the details pane, right-click SQL Server () and then click restart, to stop and restart SQL Server.

After you have configured SQL Server to listen on a specific port there are three ways to connect to a specific port with a client application:

Run the SQL Server Browser service on the server to connect to the Database Engine instance by name.

mod_fcgid: ap_pass_brigade failed in handle_request function

A site running drupal application was throwing Internal Server Error on linux plesk server.

When I checked apache error logs I noticed following logs

[Fri Mar 16 18:13:23 2012] [warn] (110)Connection timed out: mod_fcgid: ap_pass_brigade failed in handle_request function
[Fri Mar 16 18:13:34 2012] [warn] (110)Connection timed out: mod_fcgid: ap_pass_brigade failed in handle_request function
[Fri Mar 16 18:29:57 2012] [warn] (110)Connection timed out: mod_fcgid: ap_pass_brigade failed in handle_request function

The logs were appeared because php processes and traffic by site required more than the minimum total number of dynamic FastCGI application instances allowed to run at any one time without being killed off by the process manager.

In order to fix this issue we have increased the value of DefaultMaxClassProcessCount in /etc/httpd/conf.d/fcgid.conf

After that reconfigured plesk configuraation by running plesk utility websrvmng and restarted httpd service.

“/usr/local/psa/admin/sbin/websrvmng -av”

/etc/init.d/httpd restart
