4.3 Example Plug-in

The example contained in this section is for a template that updates a configuration

file which specifies a list of client computer system names. The template is used with

the cmgr command to add, delete, replace, and list entries from the configuration file.

The add operation requires the user to specify a system name (represented with the

system_name variable) and a tag identifier (represented with the tagid variable).

tagid may be an arbitrary character string. The system_name variable is checked to

ensure it responds to a ping(1M) after which the configuration file is updated. An entry

in the configuration file is in the format:

client=system_name # tagid

For a delete operation, the user is prompted to enter the tagid value. All entries in

the file with a tag field that exactly matches the tagid variable specified via cmgr are

deleted.

The replace operation functions like a delete operation, followed by an add

operation.

The list operation will list the entire contents of the configuration file if cmgr’s verbose

option is specified. Otherwise list will only list lines from the configuration file with

a matching tag value.

To create and use a template that updates a configuration file that specifies a list of

client computer system names, follow these steps:

1. Modify the CMGR DTD (/etc/opt/cmgr/templates/cmgr.dtd) for the

myconf element:

<!ELEMENT template (head, prologue?, body)>

<!ELEMENT head (title|description|cst_version|template_version|

<!ELEMENT prologue

<!ELEMENT body

… lines deleted for readability …

<!ELEMENT myconf (data|help|success|failure)*>

… lines deleted for readability …

<!ATTLIST myconf

config_file CDATA #IMPLIED

id CDATA #IMPLIED

if_op CDATA #IMPLIED

if CDATA #IMPLIED

… lines deleted for readability …
