Groups of hosts.
|
|
|
|
Manage groups of hosts. This is useful for applying access control to a
|
|
number of hosts by using Host-based Access Control.
|
|
|
|
EXAMPLES:
|
|
|
|
Add a new host group:
|
|
ipa hostgroup-add --desc="Baltimore hosts" baltimore
|
|
|
|
Add another new host group:
|
|
ipa hostgroup-add --desc="Maryland hosts" maryland
|
|
|
|
Add members to the hostgroup (using Bash brace expansion):
|
|
ipa hostgroup-add-member --hosts={box1,box2,box3} baltimore
|
|
|
|
Add a hostgroup as a member of another hostgroup:
|
|
ipa hostgroup-add-member --hostgroups=baltimore maryland
|
|
|
|
Remove a host from the hostgroup:
|
|
ipa hostgroup-remove-member --hosts=box2 baltimore
|
|
|
|
Display a host group:
|
|
ipa hostgroup-show baltimore
|
|
|
|
Delete a hostgroup:
|
|
ipa hostgroup-del baltimore
