Create a Security Group
Eucalyptus enables you to control access to your cloud using security groups. A
security group contains a group of rules that control inbound traffic to instances in the
group for the specified protocols and ports.
Create a Security Group with the Console
-
Enter a name for your security group in the Name
text box.
-
Enter a description for your security group in the
Description text box.
-
You can optionally create one or more rules for the security group. A
rule grants a specified range of IP addresses inbound
access to your instances for a protocol or custom port range. Rules for many of the most
popular protocols are pre-defined and available for selection in the
drop-down list box, or you can define your own rule.
Important: You should specify at least one rule for your security group.
-
Select a protocol for the rule from the
Protocol drop-down list box, or select a custom protocol.
-
If you've selected a custom protocol, enter a port range for the rule in the Port
range text box.
-
Select the type of inbound traffic for the rule using the radio
buttons:
To grant access to an IP address or range of IP addresses, select
the IP Address radio button and enter a
CIDR range in the text box.
To grant access to another security group, select the
Other security group radio button and
enter the name of the security group in the text box.
Note: To specify a security group in another account, use the
format "userid/groupname".

Click the Add another rule button.
