NAME

getnewkeys - Download pending Kerberos key updates

SYNOPSIS

getnewkeys [-q] [-k keytab] [-r realm] [-s server] [-P serverprinc] [-a] [-p principalname]

DESCRIPTION

getnewkeys is used to download new Kerberos keys from rekeysrv(8), store them into the specified keytab, and send a "commit" message, informing the server that the new keys have been received and safely stored. When the last host in a rekey cycle commits the new keys, the server automatically adds them to the Kerberos database.

OPTIONS

-q

Avoid printing an error message when the server does not have any keys to send.

-k keytab

Specifies the keytab into which downloaded keys should be stored, instead of the Kerberos default keytab.

-r realm

Specifies the realm in which rekeying is done. This is currently used only to determine the default server name when -s is not given.

-s server

Specifies the hostname of the rekey server. The default is to form a hostname by prepending "rekey." to the realm name specified via the -r option, or to the default realm if -r is not given.

-P serverprinc

Specifies the Kerberos service principal name of the rekey server. If '-' is given, the rekey server's host principal is used. The default is @def_rekey_service@

-a

Download all keys the server has for this host, instead of only those for principals already listed in the keytab.

-p principalname

Download only keys for the specified principalname.

CAVEATS

Because the server stores and compares principal names as strings, the principal name argument to -p usually must be in canonical form, including the realm. Failing to follow this rule will generally result in confusing errors.
