KF(1) BSD General Commands Manual KF(1)
NAME
kf -- securely forward tickets
SYNOPSIS
kf [-p port | --port=port] [-l login | --login=login] [-c ccache | --ccache=ccache] [-F | --forwardable] [-G | --no-forwardable]
[-h | --help] [--version] host ...
DESCRIPTION
The kf program forwards tickets to a remote host through an authenticated and encrypted stream. Options supported are:
-p port, --port=port
port to connect to
-l login, --login=login
remote login name
-c ccache, --ccache=ccache
remote cred cache
-F, --forwardable
forward forwardable credentials
-G, --no-forwardable
do not forward forwardable credentials
-h, --help
--version
kf is useful when you do not want to enter your password on a remote host but want to have your tickets one for example AFS.
In order for kf to work you will need to acquire your initial ticket with forwardable flag, i.e. kinit --forwardable.
telnet is able to forward tickets by itself.

KINIT(1) BSD General Commands Manual KINIT(1)
NAME
kinit -- acquire initial tickets
SYNOPSIS
kinit [--afslog] [-c cachename | --cache=cachename] [--canonicalize] [-f | --no-forwardable] [-t keytabname | --keytab=keytabname] [-l time |
--lifetime=time] [-p | --proxiable] [-R | --renew] [--renewable] [-r time | --renewable-life=time] [-S principal | --server=principal]
[-s time | --start-time=time] [-k | --use-keytab] [-v | --validate] [-e enctypes | --enctypes=enctypes] [-a addresses |
--extra-addresses=addresses] [--password-file=filename] [--fcache-version=version-number] [-A | --no-addresses] [--anonymous]
[--enterprise] [--version] [--help] [principal [command]]
DESCRIPTION
kinit is used to authenticate to the Kerberos server as principal, or if none is given, a system generated default (typically your login name
at the default realm), and acquire a ticket granting ticket that can later be used to obtain tickets for other services.
Supported options:
-c cachename --cache=cachename
The credentials cache to put the acquired ticket in, if other than default.
-canonicalize
ask the KDC canonicalize the client name and server name. Useful with enterprise names, PK-INIT, and LKDC realms when the user
doesn't know its real kerberos user name.
-f, --forwardable
Get ticket that can be forwarded to another host.
-t keytabname, --keytab=keytabname
-f --no-forwardable
Get ticket that can be forwarded to another host, or if the negative flags use, don't get a forwardable flag.
-t keytabname, --keytab=keytabname
Don't ask for a password, but instead get the key from the specified keytab.
-l time, --lifetime=time
Specifies the lifetime of the ticket. The argument can either be in seconds, or a more human readable string like '1h'.
-p, --proxiable
Request tickets with the proxiable flag set.
-R, --renew
Try to renew ticket. The ticket must have the 'renewable' flag set, and must not be expired.
--renewable
The same as --renewable-life, with an infinite time.
-r time, --renewable-life=time
The max renewable ticket life.
-S principal, --server=principal
Get a ticket for a service other than krbtgt/LOCAL.REALM.
-s time, --start-time=time
Obtain a ticket that starts to be valid time (which can really be a generic time specification, like '1h') seconds into the future.
-k, --use-keytab
The same as --keytab, but with the default keytab name (normally FILE:/etc/krb5.keytab).
-v, --validate
Try to validate an invalid ticket.
-e, --enctypes=enctypes
Request tickets with this particular enctype.
--password-file=filename
read the password from the first line of filename. If the filename is STDIN, the password will be read from the standard input.
--fcache-version=version-number
Create a credentials cache of version version-number.
-a, --extra-addresses=enctypes
Adds a set of addresses that will, in addition to the systems local addresses, be put in the ticket. This can be useful if all
addresses a client can use can't be automatically figured out. One such example is if the client is behind a firewall. Also set-
table via libdefaults/extra_addresses in krb5.conf(5).
-A, --no-addresses
Request a ticket with no addresses.
--anonymous
Request an anonymous ticket (which means that the ticket will be issued to an anonymous principal, typically ``anonymous@REALM'').
-V, --verbose
Print slightly more verbose output from kinit when successful.
--enterprise
Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enterprise names are email like principals that are stored in the name
part of the principal, and since there are two @ characters the parser needs to know that the first is not a realm. An example of an
enterprise name is ``lha@e.kth.se@KTH.SE'', and this option is usually used with canonicalize so that the principal returned from the
KDC will typically be the real principal name.
--afslog
Gets AFS tickets, converts them to version 4 format, and stores them in the kernel. Only useful if you have AFS.
The forwardable, proxiable, ticket_life, and renewable_life options can be set to a default value from the appdefaults section in krb5.conf,
see krb5_appdefault(3).
If a command is given, kinit will set up new credentials caches, and AFS PAG, and then run the given command. When it finishes the creden-
tials will be removed.
ENVIRONMENT
KRB5CCNAME
Specifies the default credentials cache.
KRB5_CONFIG
The file name of krb5.conf, the default being /etc/krb5.conf.
KRBTKFILE
Specifies the Kerberos 4 ticket file to store version 4 tickets in.
