command [args] |
ktutil
is a program for managing keytabs. Supported
options:
-v
,
-
-verbose
- Verbose output.
command can be one of the following:
- add [
-p
principal]
[-
-principal=
principal]
[-V
kvno]
[-
-kvno=
kvno]
[-e
enctype]
[-
-enctype=
enctype]
[-w
password]
[-
-password=
password]
[-r
]
[-
-random
]
[-s
]
[-
-no-salt
]
[-H
]
[-
-hex
]
- Adds a key to the keytab. Options that are not specified will be prompted
for. This requires that you know the password or the hex key of the
principal to add; if what you really want is to add a new principal to the
keytab, you should consider the get command, which
talks to the kadmin server.
- change [
-r
realm]
[-
-realm=
realm]
[-
-a
host]
[-
-admin-server=
host]
[-
-s
port]
[-
-server-port=
port]
- Update one or several keys to new versions. By default, use the admin
server for the realm of a keytab entry. Otherwise it will use the values
specified by the options.
If no principals are given, all the ones in the keytab are
updated.
- copy keytab-src
keytab-dest
- Copies all the entries from keytab-src to
keytab-dest.
- get [
-p
admin principal]
[-
-principal=
admin
principal] [-e
enctype]
[-
-enctypes=
enctype]
[-r
realm]
[-
-realm=
realm]
[-a
admin server]
[-
-admin-server=
admin
server] [-s
server port]
[-
-server-port=
server
port] principal ...
- For each principal, generate a new key for it
(creating it if it doesn't already exist), and put that key in the keytab.
If no realm is specified, the realm to
operate on is taken from the first principal.
- list [
-
-keys
]
[-
-timestamp
]
- List the keys stored in the keytab.
- remove [
-p
principal]
[-
-principal=
principal]
[-V
-kvno
]
[-
-kvno=
kvno]
[-e
-enctype
]
[-
-enctype=
enctype]
- Removes the specified key or keys. Not specifying a
kvno removes keys with any version number. Not
specifying an enctype removes keys of any type.
- rename from-principal
to-principal
- Renames all entries in the keytab that match the
from-principal to
to-principal.
- purge
[
-
-age=
age]
- Removes all old versions of a key for which there is a newer version that
is at least age (default one week) old.
