Before you start configuring Gibraltar with GibADMIN we will give you a quick overview about the user interface. While configuring Gibraltar, avoid using the Forward and the Back button of the browser. Nevertheless, if you use the buttons you will get a suitable message in GibADMIN.
Link A link indicates a navigation to another page in GibADMIN and acts the same way as a link to another HTML page. Links can be found e.g. on the left side in the main menu.
Buttons After clicking a button, a command is executed in the background; it e.g. stores the changes you made in the form. It is also possible to be redirected to another page by clicking a button (like a link). It is very important that you confirm any changes you made in a form by clicking a button so that the data can be saved permanently. The following buttons are available in GibADMIN:
Textfield You have to make entries in a textfield to perform a certain configuration. Textfields are used if the entries can not be selected from a select box or another option. Every entry in a textfield is checked so that the value fits in a predefined context. For example if we have a field that should contain an IP address you are only allowed to put values like a.b.c.d, where a, b, c and d have to be between 0 and 255. If GibADMIN checks that you inserted a wrong value, a suitable error message is displayed and points at the textfield that caused the error.
Select Box In a select box you can select a value out of a predefined range of values. This is possible if the values have been reducted unto some few predifined values.
Checkbox A checkbox offers the possibility to choose between two states. That are decisions like yes/no or activated/deactivated. The checkbox is activated if a tick is in the checkbox. You can change the state by clicking the left mouse button on the checkbox.
Option field Option fields are used when more possibilities are available from which only one can be selected. The current selected option field is marked with a black dot.
Element group An element group is a kind of representation in GibADMIN, which allows to represent identical elements in a table. For every element in a list, a row will be created. Some register cards allow to configure the elements in the element group or to go to a detail form by clicking a button. In some element groups it's possible to delete more than one entry at the same time. If there appears a delete symbol
CIDR - Classless Inter-Domain Routing GibADMIN uses the CIDR notation to enter IP addresses in conjunction with the subnet mask. A CIDR address includes the standard 32-bit IP address and also information of how many bits are used for the network prefix. For example, in the CIDR address 192.168.0.1/24, the "/24" indicates the first 24 bits are used to identify the unique network leaving the remaining bits to identify the specific host. The last valid address of this network is consequently 192.168.0.254/24. The CIDR block - this is the slash with the number - can have values from "/13" to "/27".
Some examples:
255.255.0.0 corresponding /16 255.255.255.0 corresponding /24 255.255.255.192 corresponding /26 |
