NAME
ktutil - manage Kerberos keytabs
SYNOPSIS
ktutil [-k keytab | --keytab=keytab] [-v | --verbose] [--version]
[-h | --help] command [args]
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.
srvconvert
srv2keytab [-s srvtab] [--srvtab=srvtab]
Converts the version 4 srvtab in srvtab to a version 5 keytab
and stores it in keytab. Identical to:
ktutil copy krb4:srvtab keytab
srvcreate
key2srvtab [-s srvtab] [--srvtab=srvtab]
Converts the version 5 keytab in keytab to a version 4 srvtab
and stores it in srvtab. Identical to:
ktutil copy keytab krb4:srvtab
