KDESTROY(1) 4.0 KDESTROY(1) NNAAMMEE kdestroy - destroy Kerberos tickets SSYYNNOOPPSSIISS kkddeessttrrooyy [ --ff ] [ --qq ] DDEESSCCRRIIPPTTIIOONN The _k_d_e_s_t_r_o_y utility destroys the user's active Kerberos authorization tickets by writing zeros to the file that con- tains them. If the ticket file does not exist, _k_d_e_s_t_r_o_y displays a message to that effect. After overwriting the file, _k_d_e_s_t_r_o_y removes the file from the system. The utility displays a message indicating the success or failure of the operation. If _k_d_e_s_t_r_o_y is unable to destroy the ticket file, the utility will warn you by making your terminal beep. In the Athena workstation environment, the _t_o_e_h_o_l_d service automatically destroys your tickets when you end a worksta- tion session. If your site does not provide a similar ticket-destroying mechanism, you can place the _k_d_e_s_t_r_o_y com- mand in your ._l_o_g_o_u_t file so that your tickets are destroyed automatically when you logout. The options to _k_d_e_s_t_r_o_y are as follows: --ff _k_d_e_s_t_r_o_y runs without displaying the status message. --qq _k_d_e_s_t_r_o_y will not make your terminal beep if it fails to destroy the tickets. FFIILLEESS KRBTKFILE environment variable if set, otherwise /tmp/tkt[uid] SSEEEE AALLSSOO kerberos(1), kinit(1), klist(1) BBUUGGSS Only the tickets in the user's current ticket file are des- troyed. Separate ticket files are used to hold root instance and password changing tickets. These files should probably be destroyed too, or all of a user's tickets kept in a single ticket file.
