NAME¶

kvno - print key version numbers of Kerberos principals

SYNOPSIS¶

kvno [-q] [-h] [-c ccache] [-e etype] 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

-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 krb5_sname_to_principal() will be used to build principal names. If this flag is specified, the service1 service2 ... arguments are interpreted as hostnames (rather than principal names), and sname is interpreted as the service name.

-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¶

/tmp/krb5cc_[uid]

default location of the credentials cache ([uid] is the decimal UID of the user).
