newkey
newkey(1M) System Administration Commands newkey(1M)NAME
newkey - create a new Diffie-Hellman key pair in the publickey database
SYNOPSIS
newkey -h hostname [-s nisplus | nis | files | ldap]
newkey -u username [-s nisplus | nis | files | ldap]
DESCRIPTION
newkey establishes new public keys for users and machines on the network. These keys are needed when using secure RPC or secure NFS ser-
vice.
newkey prompts for a password for the given username or hostname and then creates a new public/secret Diffie-Hellman 192 bit key pair for
the user or host. The secret key is encrypted with the given password. The key pair can be stored in the /etc/publickey file, the NIS pub-
lickey map, or the NIS+ cred.org_dir table.
newkey consults the publickey entry in the name service switch configuration file (see nsswitch.conf(4)) to determine which naming service
is used to store the secure RPC keys. If the publickey entry specifies a unique name service, newkey will add the key in the specified name
service. However, if there are multiple name services listed, newkey cannot decide which source to update and will display an error mes-
sage. The user is required to specify the source explicitly with the -s option.
In the case of NIS, newkey should be run by the superuser on the master NIS server for that domain. In the case of NIS+, newkey should be
run by the superuser on a machine which has permission to update the cred.org_dir table of the new user/host domain.
In the case of NIS+, nisaddcred(1M) should be used to add new keys. newkey cannot be used to create keys other than 192-bit Diffie-Hellman.
In the case of LDAP, newkey should be run by the superuser on a machine that also recognizes the directory manager's bind distinguished
name (DN) and password to perform an LDAP update for the host.
OPTIONS -h hostname Create a new public/secret key pair for the privileged user at the given hostname. Prompts for a password for the given
hostname.
-u username Create a new public/secret key pair for the given username. Prompts for a password for the given username.
-s nisplus Update the database in the specified source: nisplus (for NIS+), nis (for NIS), files, or ldap (LDAP). Other sources may be
-s nis available in the future.
-s files
-s ldap
