klist - list currently held Kerberos tickets
[ [-c] [-f] [-s] [-a [-n]] [cache_name]]
[-k [-t] [-K] [keytab_file]]
The klist utility prints the name of the credentials cache,
the identity of the principal that the tickets are for (as listed in the
ticket file), and the principal names of all Kerberos tickets currently held
by the user, along with the issue and expiration time for each
authenticator. Principal names are listed in the form
name/instance@realm, with the '/'
omitted if the instance is not included, and the '@' omitted if the
realm is not included.
If cache_file or keytab_name is not specified,
klist displays the credentials in the default credentials cache or
keytab files as appropriate. By default, your ticket is stored in the file
/tmp/krb5cc_uid, where uid is the current user-ID of
The following options are supported:
Displays list of addresses in credentials. Uses the
configured nameservice to translate numeric network addresses to the
associated hostname if possible.
Lists tickets held in a credentials cache. This is the
default if neither -c nor -k is specified.
Displays the encryption types of the session key and the
ticket for each credential in the credential cache, or each key in the keytab
Shows the flags present in the credentials, using the
Okay as delegate
Transit policy checked
List keys held in a keytab file.
Displays the value of the encryption key in each keytab
entry in the keytab file.
Shows numeric IP addresses instead of
reverse-resolving addresses. Only valid with -a option.
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 `1if it does not, or if the local-realm TGT has expired.
Displays the time entry timestamps for each keytab entry
in the keytab file.
klist uses the following environment variable:
Location of the credentials (ticket) cache. See
for syntax and details.
Default credentials cache (uid is the decimal
UID of the user).
Default location for the local host's keytab
Default location for the local host's configuration file.
