klist - list cached Kerberos tickets

klist [-5] [-4] [-e] [[-c] [-f] [-s] [-a [-n]]] [-k [-t] [-K]] [cache_name | keytab_name]

Klist lists the Kerberos principal and Kerberos tickets held in a credentials cache, or the keys held in a keytab file. If klist was built with Kerberos 4 support, the default behavior is to list both Kerberos 5 and Kerberos 4 credentials. Otherwise, klist will default to listing only Kerberos 5 credentials.

-5

list Kerberos 5 credentials. This overrides whatever the default built-in behavior may be. This option may be used with -4

-4

list Kerberos 4 credentials. This overrides whatever the default built-in behavior may be. This option is only available if kinit was built with Kerberos 4 compatibility. This option may be used with -5

-e

displays the encryption types of the session key and the ticket for each credential in the credential cache, or each key in the keytab file.

-c

List tickets held in a credentials cache. This is the default if neither -c nor -k is specified.

-f

shows the flags present in the credentials, using the following abbreviations:

F	Forwardable
f	forwarded
P	Proxiable
p	proxy
D	postDateable
d	postdated
R	Renewable
I	Initial
i	invalid
H	Hardware authenticated
A	preAuthenticated
T	Transit policy checked
O	Okay as delegate
a	anonymous

-s

causes klist to run silently (produce no output), but to still set the exit status according to whether it finds the credentials cache. The exit status is `0' if klist finds a credentials cache, and `1' if it does not or if the tickets are expired.

-a

display list of addresses in credentials.

-n

show numeric addresses instead of reverse-resolving addresses.

-k

List keys held in a keytab file.

-t

display the time entry timestamps for each keytab entry in the keytab file.

-K

display the value of the encryption key in each keytab entry in the keytab file.

If cache_name or keytab_name is not specified, klist will display the credentials in the default credentials cache or keytab file as appropriate. If the KRB5CCNAME environment variable is set, its value is used to name the default ticket cache.

Klist uses the following environment variables:

KRB5CCNAME

Location of the Kerberos 5 credentials (ticket) cache.

KRBTKFILE

Filename of the Kerberos 4 credentials (ticket) cache.

/tmp/krb5cc_[uid]

default location of Kerberos 5 credentials cache ([uid] is the decimal UID of the user).

/tmp/tkt[uid]

default location of Kerberos 4 credentials cache ([uid] is the decimal UID of the user).

/etc/krb5.keytab

default location for the local host's keytab file.

kinit(1), kdestroy(1), krb5(3)
