Using Parallels Pro Control Panel to change the logo

To upload your logo to the server:

In the shortcuts area of the Home page, Click Upload Logo (Configuration section).
In the Upload new logo field, enter the name of your custom logo file including the full path or click

Browse to locate and select the file on your computer.
Note: Your logo size should not exceed 73 x 46 pixels.
Click Upload Logo.

Using the command line to change the logo

Using SSH, log on to the server as the root user.

Use either the move (mv) or copy (cp) command to move your logo.gif file to the customization directory /etc/appliance/customization/. For example:

mv /home/ftp_username/logo.gif /etc/appliance/customization/logo.gif

Where ftp_username is the user name of your FTP user account on the server.


IP-based and name-based Web sites

IP-based and name-based Web sites.

There are two ways to host domains. The first is to create the domain with its own IP address. This is called IP-based hosting. You must create IP-based domains if the domain needs anonymous FTP and its own secure-site (SSL) support.

The second way to host domains is to create a domain that shares the primary IP address of the server. This is called name-based hosting. Name-based domains receive most of the benefits of an IP-based domain without occupying an IP address.

All of the standard sets of server applications are available to IP-based and name-based sites, except SSL encryption. SSL is not supported for name-based sites.

IP addresses happen to be scarce resources. To conserve IP addresses, you can arrange to have many sites share the same IP address.


Creating Ensim Service Plan templates

To create a Service Plan template:

In the shortcuts section of the Home page, click Add Service Plan (Sites section).
Use the Service Plan Options Information to help you complete the form.
In the Save Plan area, save the plan as a new template or overwrite an existing template.

Before creating sites, you might want to create Service Plan templates. These templates are not required to create a site; however, they can make creating multiple sites easier and faster by establishing the services and utilities you want to assign to specific sites when you create them.

To save the plan as a new plan, select the Save as a new plan option. In the adjacent text box, enter the name of the new plan.

To update or overwrite an existing plan, select the Save as an existing plan option. From the list, click the arrow and choose a name.

To save this plan as the default plan, click the arrow and choose default.

Click Save.

Troubleshooting Ensim Upgrade or Installer Issues

Problem : The host name of the server is incorrect.

Refer the log file /var/log/ensim/installer..-.log to review the list of successful and unsuccessful events recorded during the upgrade.

Check the file /etc/sysconfig/network. The host name must be a fully qualified domain name. See the following example.


The file /etc/hosts should contain the host name and IP address of your server. If it does not, use an editor to modify the file.

—/etc/hosts begin file– localhost.localdomain localhost myhost
—/etc/hosts end file–

Minimum Requirements to upgrade to Parallels Pro Control Panel

To upgrade to Parallels Pro Control Panel, your system needs to meet the following requirements.

Disk space At least 40 GB

/ 5 GB or more
/usr 5 GB or more
/swap Twice the size of RAM
/var 4 GB or more
20 GB or more (depending on the number of sites you want to host)

Important: Do not create /home/virtual on a separate partition. The Site Administrator dashboard reports incorrect disk usage if the directory is created on a separate partition.

Note: Sites hosted on Parallels Pro Control Panel will be accessible during the upgrade and services such as Web, FTP, and Email will continue to function, except when the site is being upgraded. However, the control panels will be inaccessible during the upgrade. This could typically range from a few minutes to a few hours depending on the number of sites hosted on the server.
