DESCRIPTION
The pntadm command is used to manage the Dynamic Host Configuration
Protocol (DHCP) network tables. It is used to add and remove networks
under DHCP management, and add, delete, or modify IP address records
within network tables, or to view tables. For a description of the for‐
mat of DHCP network tables, see dhcp_network(4).
pntadm can be run as root or by other users assigned to the DHCP Man‐
agement profile. See rbac(5) and user_attr(4).
If the networks you want to add are subnetted, you need to update the
netmasks(4) table.
One of the following options (function flags) must be specified with
the pntadm command: -A, -B, -C, -D, -L, -M, -P, or-R.
OPTIONS
The following options are supported:
-A name_IP_address
Add a client entry with hostname or client IP address,
name_IP_address, to the named DHCP network table.
The following sub-options are optional:
-c comment
Comment text. The default is NULL.
-e mm/dd/yyyy
Absolute lease. The default is 0.
-f num | keywords
Flag value. The default is 00.
The flag (-f) option can be specified either as a single number
denoting the intended flag value, or as a series of the follow‐
ing keywords, combined using the plus (+) symbol:
DYNAMIC or 00
Server manager's assignment.
PERMANENT or 01
Lease on entry is permanent.
MANUAL or 02
Administrator managed assignment.
UNUSABLE or 04
Entry is not valid.
BOOTP or 08
Entry reserved for BOOTP clients.
For a more detailed description of the flag values, see
dhcp_network(4).
-h client_hostname
Client hostname. The default is NULL.
When the -h option is used in this mode, the client_hostname is
added to the hosts table within the resource used for storing
host names (files or DNS). The command will fail if this
client_hostname is already present in the hosts table.
-i client_ID [-a]
Client identifier [-a]. The default is 00.
The -i option modified with -a specifies that the client iden‐
tifier is in ASCII format, and thus needs to be converted to
hexadecimal format before insertion into the table.
-m macro [-y]
Macro name. Default is UNKNOWN.
The -m option modified with -y verifies the existence of the
named macro in the dhcptab table before adding the entry.
-s server
Server IP or name. Default is system name (uname -n).
-B
Activate batch mode. pntadm will read from the specified file or
from standard input a series of pntadm commands and execute them
within the same process. Processing many pntadm commands using this
method is much faster than running an executable batchfile itself.
Batch mode is recommended for using pntadm in scripts.
The following sub-option is optional:
-v
Display commands to standard output as they are processed.
-C
Create the DHCP network table for the network specified by network.
See . For details, see dhcp_network(4) and networks(4).
-D name_IP_address
Delete the specified client entry with hostname or client IP
address, name_IP_address, in the named DHCP network table. (See
dhcp_network(4).)
The following sub-option is optional:
-y
Remove associated host table entry. The -y option requests that
all hostnames associated with the IP address in the hosts table
in the resource be removed.
-L
List the DHCP network tables presently configured, one per line, on
standard output. If none are found, no output is printed and an
exit status of 0 is returned.
-M name_IP_address
Modify the specified client entry with hostname or client IP
address, name_IP_address, in the named DHCP network table. See
dhcp_network(4). The default for the sub-options is what they cur‐
rently are set to.
The following sub-options are optional.
-c comment
New comment text.
-e mm/dd/yy
New absolute lease expiration date. Time defaults to 12:00 AM
of the day specified.
-f num | keyboard
New flag value, see explanation following the description of
the -A option.
-h host_name
New client hostname.
The -h option allows you to change the current hostname associ‐
ated with the IP address or to add a new hostname to the hosts
table if an entry associated with this IP address does not
exist.
-i client_ID
New client identifier [-a].
-m macro [-y]
Macro name defined in dhcptab.
-n new_client_IP_address
New IP address.
-s server
New server IP or name.
For more detailed description of the sub-options and flag values,
see dhcp_network(4).
-P
Display the named DHCP network table.
The following sub-options are optional:
-v
Display lease time in full verbose format and resolve IP
addresses for the clients and server to hostnames.
-x
Display lease time in raw format.
These flag codes are used with the -P sub-options:
-v-x Description
D 00 DYNAMIC
P 01 PERMANENT
M 02 MANUAL
U 04 UNUSABLE
B 08 BOOTP
See dhcp_network(4) for information on these sub-options and asso‐
ciated flag codes.
-p path
Override the dhcpsvc.conf(4) configuration value for data store
resource path, path See dhcpsvc.conf(4)-R
Remove the named DHCP network table. See dhcp_network(4).
-r data_store_resource
Override the /etc/inet/dhcpsvc.conf configuration value for
RESOURCE= with the data_store_resource specified. See the
dhcpsvc.conf(4) man page for more details on resource type, and the
for more information about adding support for other data stores.
-u uninterpreted
Data which will be ignored by pntadm, but passed to the currently
configured public module to be interpreted by the data store. This
might be used for a database account name or other authentication
or authorization parameters required by a particular data store.
OPERANDS
The following operand is supported:
network
The network address or network name which corresponds to the dhcp
network table. See dhcp_network(4).
EXAMPLES
Example 1 Creating a Table for the 10.0.0.0 DHCP Network
The following command creates a table for the 10.0.0.0 (subnetted to
class C) DHCP network table. Note that if you have an alias for this
network in your networks(4) table, you can use that value rather than
the dotted Internet Address notation.
example# pntadm-C 10.0.0.0
Example 2 Adding an Entry to the 10.0.0.0 Table
The following command adds an entry to the 10.0.0.0 table in the files
resource in the /var/mydhcp directory:
example# pntadm-r SUNWfiles -p /var/mydhcp -A 10.0.0.1 10.0.0.0
Example 3 Modifying the 10.0.0.1 Entry of the 10.0.0.0 Table
The following command modifies the 10.0.0.1 entry of the 10.0.0.0 ta‐
ble, changing the macro name to Green, setting the flags field to MAN‐
UAL and PERMANENT:
example# pntadm-M 10.0.0.1 -m Green -f 'PERMANENT+MANUAL' 10.0.0.0
Example 4 Changing the 10.0.0.1 Entry to 10.0.0.2
The following command changes the 10.0.0.1 entry to 10.0.0.2, making an
entry in the hosts(4) table called myclient:
example# pntadm-M 10.0.0.1 -n 10.0.0.2 -h myclient 10.0.0.0
Example 5 Setting the Client ID as ASCII
The following command sets the client ID as ASCII aruba.foo.com for the
myclient entry:
example# pntadm-M myclient -i 'aruba.foo.com' -a 10.0.0.0
Example 6 Deleting the myclientEntry from the 10.0.0.0 Table
The following command deletes the myclient (10.0.0.2) entry from the
10.0.0.0 table:
example# pntadm-D myclient 10.0.0.0
Example 7 Listing the Configured DHCP Network Tables
The following command lists the configured DHCP network tables:
example# pntadm-L
192.168.0.0
10.0.0.0
Example 8 Executing pntadm Commands in Batch Mode
The following command runs a series of pntadm commands contained in a
batch file:
example# pntadm-B addclients
EXIT STATUS
0
Successful completion.
1
Object already exists.
2
Object does not exist.
3
Non-critical error.
4
Critical error.
