6 trustman - Manage keys used as trust anchors
7
9 trustman [options]
10
12 trustman manages keys used by DNSSEC as trust anchors in compliance
13 with RFC5011. It may be used as a daemon for ongoing key verification
14 or manually for initialization and one-time key verification.
15 By default, trustman runs as a daemon to ensure that keys stored
17 locally in configuration files still match the same keys fetched from
18 the zone where they are defined. In addition, these checks can be run
19 once manually (-S) and in the foreground (-f).
20 For each key mismatch check, if key mismatches are detected then
22 trustman performs the following operations:
23 - sets an add hold-down timer for new keys;
25 - sets a remove hold-down timer for missing keys;
26 - removes revoked keys from the configuration file.
27 On subsequent runs, the timers are checked. If the timers have
29 expired, keys are added to or removed from the configuration file, as
30 appropriate.
31 named.conf and dnsval.conf are the usual configuration files. These
33 files must be specified in the DNSSEC-Tools configuration file or in
34 command line options.
35
37 trustman takes a number of options, each of which is described in this
38 section. Each option name may be shortened to the minimum number of
39 unique characters, but some options also have an alias (as noted.) The
40 single-letter form of each option is denoted in parentheses, e.g.:
41 -anchor_data_file (-a).
42 -anchor_data_file file (-a)
44 A persistent data file for storing new keys waiting to be added.
45 -config file (-c)
47 Create a configuration file for trustman from the command line
48 options given. The existing DNSSEC-Tools configuration file is
49 copied to the specified configuration file, and new configuration
50 entries are appended corresponding to the command line options.
51 trustman-specific entries already in the existing configuration
52 file will be replaced with new entries from the command line. This
53 will allow fewer command line options to be specified in the
54 future.
55 -dnsval_conf_file /path/to/dnsval.conf (-k)
57 A dnsval.conf file to read, and possibly be updated.
58 -dtconfig config_file (-d)
60 Name of an alternate DNSSEC-Tools configuration file to be
61 processed. If specified, this configuration file is used in place
62 of the normal DNSSEC-Tools configuration file, not in addition to
63 it. Also, it will be handled prior to keyrec files, rollrec files,
64 and command-line options.
65 -foreground (-f)
67 Run in the foreground. trustman will still run in a loop. To run
68 once, use the -single_run option instead.
69 -hold_time seconds (-w)
71 The value of the hold-down timer. This is the number of seconds
72 from the time that a new key is found. Generally, the default and
73 recommended value of 30 days should be used.
74 -mail_contact_addr email_address (-m)
76 Mail address for the contact person to whom reports should be sent.
77 -monitor (-M)
79 Indicates that trustman was run from a monitoring system, and a
80 summary of events will be printed. Specifying this option
81 automatically turns on the -single_run option and turns off the
82 -verbose option.
83 This was developed for use with the Nagios monitoring system, but
85 it can be adapted for other monitors.
86 -named_conf_file /path/to/named.conf (-n)
88 A named.conf file to read, and possibly update.
89 -nomail
91 Prevents mail from being sent, even if an SMTP server was specified
92 in the configuration file. This is useful for only sending
93 notifications via stdout (-p) or syslog (-L).
94 -norevoke
96 This option turns off checks for the REVOKE bit.
97 -no_error (-N)
99 Send report even when there are no errors.
100 -print (-p)
102 Log messages to stdout.
103 -resolv_conf_file conffile (-r)
105 A resolv.conf file to read. /dev/null can be specified to force
106 libval to recursively answer the query rather than asking other
107 name servers.)
108 -root_hints_file /path/to/root.hints (-o)
110 A root.hints file to read.
111 -single_run (-S)
113 Do not loop, but run only once.
114 -sleeptime seconds (-t)
116 The number of seconds to sleep between checks. Default is 3600
117 (one hour.)
118 -smtp_server smtpservername (-s)
120 The SMTP server that trustman should use to send reports by mail.
121 -syslog (-L)
123 Log messages to syslog.
124 -tmp_dir directory (-T)
126 Specifies where temporary files should be created. This is used
127 when creating new versions of the dnsval.conf and named.conf files
128 before they are moved into place.
129 Files created in this directory will be renamed to their final
131 location. You should ensure that this directory, the final
132 dnsval.conf location, and the final named.conf location are on the
133 same disk partition. Most operating systems will only rename files
134 within a partition and will give an error if told to rename a file
135 from one partition to another.
136 -zone zone (-z)
138 The zone to check. Specifying this option supersedes the default
139 configuration file.
140 -help (-h)
142 Display a help message.
143 -verbose (-v)
145 Gives verbose output.
146 -Version (-V)
148 Displays the version information for trustman and the DNSSEC-Tools
149 package.
150
152 In addition to the command line arguments, the dnssec-tools.conf file
153 can be configured with the following values to remove the need to use
154 some of the command-line options. The command-line options always
155 override the settings in the dnssec-tools.conf file.
156 taanchorfile file
158 This specifies the file where trustman state information will be
159 kept. This is equivalent to the -anchor_data_file flag.
160 tacontact contact_email
162 This is equivalent to the -mail_contact_addr flag for specifying to
163 whom email notices will be sent.
164 tadnsvalconffile file
166 This specifies the dnsval.conf file to read and write. This is
167 equivalent to the -dnsval_conf_file flag.
168 tanamedconffile file
170 This specifies the named.conf file to read and write. This is
171 equivalent to the -named_conf_file flag.
172 taresolvconffile file
174 This specifies the resolv.conf file to use. This is equivalent to
175 the -resolv_conf_file flag.
176 taroothintsfile file
178 This specifies the root.hints file to read. This is equivalent to
179 the -root_hints_file flag.
180 tasmtpserver servername
182 This is equivalent to the -smtp_server flag for specifying the SMTP
183 server to which email notices will be sent.
184 tatmpdir directory
186 This specifies where temporary files should be created. This is
187 used when creating new versions of the dnsval.conf and named.conf
188 files before they're moved into place.
189 See the note about renaming in the description of the -tmp_dir
191 option.
192
194 trustman may exit for the following reasons:
195 0 - Successful execution. In daemon mode, this may just mean
197 that the daemon was successfully started. The daemon itself
198 may exit with some other error.
199 1 - Invalid options were specified.
201 2 - No new-key file was specified.
203 3 - Unable to open the new-key file.
205 4 - Unable to determine a set of zones to check.
207 5 - Some form of file-management error was encountered.
