ktutil(1) User Commands ktutil(1)
NAME
ktutil - Kerberos keytab maintenance utility
SYNOPSIS
/usr/bin/ktutil
DESCRIPTION
The ktutil command is an interactive command-line interface utility for managing the keylist in keytab files. You must read in a keytab's
keylist before you can manage it. Also, the user running the ktutil command must have read/write permissions on the keytab. For example,
if a keytab is owned by root, which it typically is, ktutil must be run as root to have the appropriate permissions.
COMMANDS
clear_list Clears the current keylist.
clear
read_kt file Reads a keytab into the current keylist. You must specify a keytab file to read.
rkt file
write_kt file Writes the current keylist to a keytab file. You must specify a keytab file to write. If the keytab file already
wkt file exists, the current keylist is appended to the existing keytab file.
add_entry number Adds an entry to the current keylist. Specify the entry by the keylist slot number.
addent number
delete_entry number Deletes an entry from the current keylist. Specify the entry by the keylist slot number.
delent number
list Lists the current keylist.
l
list_request Lists available requests (commands).
lr
quit Exits utility.
exit
q
EXAMPLES
Example 1: Deleting a principal from a file
The following example deletes the host/denver@ACME.com principal from the /etc/krb5/krb5.keytab file. Notice that if you want to delete an
entry from an existing keytab, you must first write the keylist to a temporary keytab and then overwrite the existing keytab with the the
temporary keytab. This is because the wkt command actually appends the current keylist to an existing keytab, so you can't use it to over-
write a keytab.
