It can then generate a report of +host-based keytab objects that have not been found for a minimum number of +consecutive times and which were last found longer ago than a particular +date. Finally, it can purge from wallet all objects that meet those +requirements. +.PP +When run with the \f(CW\*(C`check\*(C'\fR argument, \fBwallet-unknown-hosts\fR traverses the +wallet database looking for host-based keytabs, which it recognizes by +looking for keytab objects for principals with at least one period (\f(CW\*(C`.\*(C'\fR) +after a slash (\f(CW\*(C`/\*(C'\fR). It then applies a local check followed by a \s-1DNS\s0 +check. The \s-1DNS\s0 check is only successful (only considers the host to be +found) if it resolves to an \s-1IP\s0 address (possibly through a \s-1CNAME\s0). +.PP +For any host that's not found, it records that host in its associated +database. If this is the first time it wasn't found, it records the first +missing time as the current time and the missing count as 1. If it +previously wasn't found, it just increments the missing count. +.PP +For any host that is found, it deletes any record for that keytab from the +database. +.PP +When run with the \f(CW\*(C`report\*(C'\fR argument, \fBwallet-unknown-hosts\fR takes two +additional arguments: \fImin\fR and \fIdate\fR. \fImin\fR is the minimum number of +times that a host must be found missing for the corresponding keytabs to +show up on the report. \fIdate\fR is a cutoff date in seconds since epoch; +keytabs will not be included in the report unless their first missing date +is older than \fIdate\fR. The output will be the name component of the +keytab objects in the wallet that correspond to unknown hosts and meet +those thresholds. +.PP +When run with the \f(CW\*(C`purge\*(C'\fR argument, \fBwallet-unknown-hosts\fR will build a +list of keytab objects the same as with the \f(CW\*(C`report\*(C'\fR argument, using the +same additional arguments, but rather than printing them out will instead +delete them from the wallet database. To run \f(CW\*(C`purge\*(C'\fR, the environment +variable \s-1REMOTE_USER\s0 must be set to a principal that's a member of the +\&\f(CW\*(C`ADMIN\*(C'\fR \s-1ACL.\s0 +.SH "BUGS" +.IX Header "BUGS" +\&\fBwallet-unknown-hosts\fR doesn't have any facility to purge from its +database all objects that are no longer in the wallet. +.PP +Having to specify an identity for purge mode is an artifact of the +Wallet::Server \s-1API\s0 and needs to be fixed by providing some way to perform +actions as a local administrator. +.SH "AUTHOR" +.IX Header "AUTHOR" +Russ Allbery <eagle@eyrie.org> +.SH "COPYRIGHT AND LICENSE" +.IX Header "COPYRIGHT AND LICENSE" +Copyright 2010, 2013 The Board of Trustees of the Leland Stanford Junior +University +.PP +Permission is hereby granted, free of charge, to any person obtaining a +copy of this software and associated documentation files (the \*(L"Software\*(R"), +to deal in the Software without restriction, including without limitation +the rights to use, copy, modify, merge, publish, distribute, sublicense, +and/or sell copies of the Software, and to permit persons to whom the +Software is furnished to do so, subject to the following conditions: +.PP +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. +.PP +\&\s-1THE SOFTWARE IS PROVIDED \*(L"AS IS\*(R", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\s0 \s-1IN NO EVENT SHALL +THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER +LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING +FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER +DEALINGS IN THE SOFTWARE.\s0 +.PP +SPDX-License-Identifier: \s-1MIT\s0 |
