pntadm −P [ −v ] [ −r resource ] [ −p path ] network

pntadm −R [ −r resource ] [ −p path ] network

DESCRIPTION

The pntadm command manages the dhcp network DHCP client tables.  One of the following option flags must be specified: −C, −A, −M, −D, or −R. 

Note also that if the networks you wish to add are subnetted, you will need to update the netmasks(4) table.  Depending on the resource type (−r option), you must have the proper file permissions or NIS+ credentials. 

For a description of the format of dhcp network tables, see dhcp_network(4). 

OPTIONS

−A name_IP_address
Add a client entry with hostname or client IP address, name_IP_address, to the named dhcp network table.  Optional sub-options, with defaults, are:

The flag (−f) option can be specified either as a single number denoting the intended flag value, or a series of the following keywords, combined using the plus (+) symbol:

For a more detailed description of the flag values, see dhcp_network(4).  The −i option modified with −a specifies that the client identifier is in ASCII format, and thus needs to be converted to hexadecimal format before insertion into the table.  The −m option modified with −y verifies the existence of the named macro in the dhcptab table before adding the entry. 

−C Create the DHCP network table for the network specified by network (see OPERANDS).  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).)   Optional sub-options are:

−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).)   Optional sub-options are:

For more detailed description of the sub-options and flag values, see the information given under −A option above and dhcp_network(4). 

−P Display the named dhcp network table.  See dhcp_network(4).  Optional sub-options are:

−p path Override the /etc/default/dhcp configuration value for resource path, path. The resource path for the files resource is an absolute UNIX pathname and a fully specified nisplus directory (including the tailing period) for the NIS+ resource.  See dhcp(4) for more details. 

−R Remove the named dhcp network table.  See dhcp_network(4). 

−r resource Override the /etc/default/dhcp configuration value for resource type, resource. Currently supported resource types are files or nisplus.  See dhcp(4) for more details. 

OPERANDS

network The network address or network name which corresponds to the dhcp network table.  See dhcp_network(4). 

EXAMPLES

1) 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. 

# pntadm −C 10.0.0.0

2) The following command adds an entry to the 10.0.0.0 table in the files resource in the /var/mydhcp directory:

# pntadm −r files −p /var/mydhcp −A 10.0.0.1 10.0.0.0

3) The following command modifies the 10.0.0.1 entry of the 10.0.0.0 table, changing the macro name to Green, setting the flags field to MANUAL and PERMANENT:

# pntadm −M 10.0.0.1 −m Green −f ’PERMANENT + MANUAL’ 10.0.0.0

4) 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:

# pntadm −M 10.0.0.1 −n 10.0.0.2 −h myclient 10.0.0.0

5) The following command sets the client ID as ASCII aruba.foo.com for the myclient entry:

# pntadm −M myclient −i ’aruba.foo.com’ −a 10.0.0.0

6) The following command deletes the myclient (10.0.0.2) entry from the 10.0.0.0 table:

# pntadm −D myclient 10.0.0.0

7) The following command removes the named dhcp network table in the nisplus directory specified:

# pntadm −r nisplus −p Test.Nis.Plus. −R 10.0.0.0

EXIT STATUS

0 Successful completion. 

1 Object already exists. 

2 Object does not exist. 

3 Non-critical error. 

4 Critical error. 

FILES

/var/dhcp/XXX_XXX_XXX_XXX
files or NIS+ tables where XXX represents octets of the dotted IP address

/etc/default/dhcp DHCP service configuration file

/etc/inet/hosts file or NIS+ table
