NAME¶
kvno - print key version numbers of Kerberos principals
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¶
- FILE:/tmp/krb5cc_%{uid}
- Default location of the credentials cache
