DESCRIPTION¶
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.
