.. _kvno(1):
kvno
====
SYNOPSIS
--------
**kvno**
[**-c** *ccache*]
[**-e** *etype*]
[**-q**]
[**-h**]
[**-P**]
[**-S** *sname*]
[**-U** *for_user*]
*service1 service2* ...
DESCRIPTION
-----------
kvno acquires a service ticket for the specified Kerberos principals
and prints out the key version numbers of each.
OPTIONS
-------
**-c** *ccache*
Specifies the name of a credentials cache to use (if not the
default)
**-e** *etype*
Specifies the enctype which will be requested for the session key
of all the services named on the command line. This is useful in
certain backward compatibility situations.
**-q**
Suppress printing output when successful. If a service ticket
cannot be obtained, an error message will still be printed and
kvno will exit with nonzero status.
**-h**
Prints a usage statement and exits.
**-P**
Specifies that the *service1 service2* ... arguments are to be
treated as services for which credentials should be acquired using
constrained delegation. This option is only valid when used in
conjunction with protocol transition.
**-S** *sname*
Specifies that the *service1 service2* ... arguments are
interpreted as hostnames, and the service principals are to be
constructed from those hostnames and the service name *sname*.
The service hostnames will be canonicalized according to the usual
rules for constructing service principals.
**-U** *for_user*
Specifies that protocol transition (S4U2Self) is to be used to
acquire a ticket on behalf of *for_user*. If constrained
delegation is not requested, the service name must match the
credentials cache client principal.
ENVIRONMENT
-----------
kvno uses the following environment variable:
**KRB5CCNAME**
Location of the credentials (ticket) cache.
FILES
-----
|ccache|
Default location of the credentials cache
