K5SRVUTIL(1)                                                      K5SRVUTIL(1)



NAME
       k5srvutil - host key table (keytab) manipulation utility

SYNOPSIS
       k5srvutil operation [ -i ] [ -f filename ]

DESCRIPTION
       k5srvutil  allows  a  system  manager  to list or change keys currently in his keytab or to add new keys to the
       keytab.


       Operation must be one of the following:

       list      lists the keys in a keytab showing version number and principal name.

       change    changes all the keys in the keytab to new randomly-generated keys, updating the keys in the  Kerberos
                 server's database to match by using the kadmin protocol.  If a key's version number doesn't match the
                 version number stored in the Kerberos server's database,  then the operation will fail.  The old keys
                 are  retained  so  that  existing  tickets continue to work.  If the -i flag is given, k5srvutil will
                 prompt for yes or no before changing each key.  If the -k option is used, the old and new  keys  will
                 be displayed.

       delold    Deletes  keys  that  are  not the most recent version from the keytab.  This operation should be used
                 some time after a change operation to  remove old keys.  If the -i flag is  used,  then  the  program
                 prompts the user whether the old keys associated with each principal should be removed.

       delete    deletes particular keys in the keytab, interactively prompting for each key.


       In all cases, the default file used is /etc/krb5.keytab file
        unless this is overridden by the -f option.


       k5srvutil  uses  the  kadmin  program to edit the keytab in place.  However, old keys are retained, so they are
       available in case of failure.
