Hosts/Machines

A host represents a machine. It can be used in a number of contexts:
- service entries are associated with a host
- a host stores the host/ service principal
- a host can be used in Host-based Access Control (HBAC) rules
- every enrolled client generates a host entry

ENROLLMENT:

There are three enrollment scenarios when enrolling a new client:

1. You are enrolling as a full administrator. The host entry may exist
   or not. A full administrator is a member of the hostadmin role
   or the admins group.
2. You are enrolling as a limited administrator. The host must already
   exist. A limited administrator is a member a role with the
   Host Enrollment privilege.
3. The host has been created with a one-time password.

A host can only be enrolled once. If a client has enrolled and needs to
be re-enrolled, the host entry must be removed and re-created. Note that
re-creating the host entry will result in all services for the host being
removed, and all SSL certificates associated with those services being
revoked.

A host can optionally store information such as where it is located,
the OS that it runs, etc.

EXAMPLES:

 Add a new host:
   ipa host-add --location="3rd floor lab" --locality=Dallas test.example.com

 Delete a host:
   ipa host-del test.example.com

 Add a new host with a one-time password:
   ipa host-add --os='Fedora 12' --password=Secret123 test.example.com

 Add a new host with a random one-time password:
   ipa host-add --os='Fedora 12' --random test.example.com

 Modify information about a host:
   ipa host-mod --os='Fedora 12' test.example.com

 Remove SSH public keys of a host and update DNS to reflect this change:
   ipa host-mod --sshpubkey= --updatedns test.example.com

 Disable the host Kerberos key, SSL certificate and all of its services:
   ipa host-disable test.example.com

 Add a host that can manage this host's keytab and certificate:
   ipa host-add-managedby --hosts=test2 test
""")
