| 10 | .SH NAME | |
| 11 | kdestroy \- destroy Kerberos tickets | |
| 12 | .SH SYNOPSIS | |

| 20 | .SH DESCRIPTION | |
| 21 | The | |
| 22 | .I kdestroy | |
| 23 | utility destroys the user's active | |
| 24 | Kerberos | |
| 25 | authorization tickets by writing zeros to the file that contains them. | |
| 26 | If the ticket file does not exist, | |
| 27 | .I kdestroy | |
| 28 | displays a message to that effect. | |
| 29 | .PP | |
| 30 | After overwriting the file, | |
| 31 | .I kdestroy | |
| 32 | removes the file from the system. | |
| 33 | The utility | |
| 34 | displays a message indicating the success or failure of the | |
| 35 | operation. | |
| 36 | If | |
| 37 | .I kdestroy | |
| 38 | is unable to destroy the ticket file, | |
| 39 | the utility will warn you by making your terminal beep. | |
| 40 | .PP | |
| 41 | In the Athena workstation environment, | |
| 42 | the | |
| 43 | .I toehold | |
| 44 | service automatically destroys your tickets when you | |
| 45 | end a workstation session. | |
| 46 | If your site does not provide a similar ticket-destroying mechanism, | |
| 47 | you can place the | |
| 48 | .I kdestroy | |
| 49 | command in your | |
| 50 | .I .logout | |
| 51 | file so that your tickets are destroyed automatically | |
| 52 | when you logout. | |
| 53 | .PP | |
| 54 | The options to | |
| 55 | .I kdestroy | |
| 56 | are as follows: | |
| 57 | .TP 7 | |
| 58 | .B \-f | |
| 59 | .I kdestroy | |
| 60 | runs without displaying the status message. | |
| 61 | .TP | |
| 62 | .B \-q | |
| 63 | .I kdestroy | |
| 64 | will not make your terminal beep if it fails to destroy the tickets. | |

| 71 | .SH BUGS | |
| 72 | .PP | |
| 73 | Only the tickets in the user's current ticket file are destroyed. | |
| 74 | Separate ticket files are used to hold root instance and password | |
| 75 | changing tickets. These files should probably be destroyed too, or | |
| 76 | all of a user's tickets kept in a single ticket file. | |
