B.2. General Tab

Attributes on the General tab are general attributes for a particular SGD server.

From the command line, use the Section D.16, “tarantella config list” command to list these settings, and the Section D.15, “tarantella config edit” command to edit these settings.

Changes to these attributes take effect immediately.

B.2.1. External DNS Names

Usage: Type the external DNS names of this server in the field. Separate multiple DNS names with a space and enclose each DNS name in double quotation marks (" ").

Description

The external DNS names of this server.

This attribute enables you to use different names, depending on the IP address of the client.

Only change this setting if this server is known by different names on the network, for example, inside and outside a firewall.

Each name has the following format:

IP-pattern:DNS name

IP-pattern is a regular expression, or a subnet mask, matching a client IP address. For example, 192.168.10.*, or 192.168.10.0/24.

If this server only has one name, use one line matching all clients. For example, *:www.example.com.

The order of the names is important. The DNS name for the first matching IP pattern is used.

Note

You must restart the SGD server for a change to this setting to take effect.

Command Line

Command option: --server-dns-external IP-pattern:dns-name

Usage: Replace IP-pattern with a regular expression for the client IP addresses. Replace dns-name with the external DNS name of the server. Use a comma to separate multiple DNS names.

In the following example, a DNS name of boston.example.com is used for clients with an IP address in the 192.168.10.* range. All other clients use a DNS name of www.example.com.

--server-dns-external "192.168.10.*:boston.example.com" \
"*:www.example.com"

B.2.2. User Login

Usage: Select or deselect the check box.

Description

Whether to allow users to log in to this SGD server.

To “decommission” an SGD server, deselect the check box. No users can log in and no new application sessions can start. Users currently logged in to this server, or with application sessions hosted on this server, are not affected. Users can log in to another SGD server in the array and resume application sessions hosted on this server.

Users are redirected to the web page defined by the Section B.2.3, “Redirection URL” attribute. Typically, you set this to another SGD server in the array.

Command Line

Command option: --server-login enabled | disabled

Usage: Specify enabled or disabled.

In the following example, user logins are disabled for the SGD host.

--server-login disabled

B.2.3. Redirection URL

Usage: Type a redirection URL in the field.

Description

If the SGD server does not allow users to log in, client devices are redirected to this URL.

If the attribute is not set, client devices are redirected to a page telling users that they cannot log in.

Command Line

Command option: --server-redirectionurl url

Usage: Replace url with the address of a web page to redirect to.

The following example specifies a redirection URL of www.example.com.

--server-redirectionurl "www.example.com"
