DESCRIPTION

43       sa-update automates the process of downloading and installing new rules
44       and configuration, based on channels.  The default channel is
45       updates.spamassassin.org, which has updated rules since the previous
46       release.
47
48       Update archives are verified using SHA256 and SHA512 hashes and GPG
49       signatures, by default.
50
51       Note that "sa-update" will not restart "spamd" or otherwise cause a
52       scanner to reload the now-updated ruleset automatically.  Instead,
53       "sa-update" is typically used in something like the following manner:
54
55               sa-update && /etc/init.d/spamassassin reload
56
57       This works because "sa-update" only returns an exit status of 0 if it
58       has successfully downloaded and installed an updated ruleset.
59
60       The program sa-update uses the underlying operating system umask for
61       the updated rule files it installs.  You may wish to run sa-update from
62       a script that sets the umask prior to calling sa-update.  For example:
63
64               #!/bin/sh
65               umask 022
66               sa-update
67

OPTIONS

69       --channel
70           sa-update can update multiple channels at the same time.  By
71           default, it will only access "updates.spamassassin.org", but more
72           channels can be specified via this option.  If there are multiple
73           additional channels, use the option multiple times, once per
74           channel.  i.e.:
75
76                   sa-update --channel foo.example.com --channel bar.example.com
77
78       --channelfile
79           Similar to the --channel option, except specify the additional
80           channels in a file instead of on the commandline.  This is useful
81           when there are a lot of additional channels.
82
83       --checkonly
84           Only check if an update is available, don't actually download and
85           install it.  The exit code will be 0 or 1 as described below.
86
87       --install
88           Install updates "offline", from the named tar.gz file, instead of
89           performing DNS lookups and HTTP invocations.
90
91           Files named file.sha256, file.sha512, and file.asc will be used for
92           the SHA256 and SHA512 hashes and the GPG signature, respectively.
93           The filename provided must contain a version number of at least 3
94           digits, which will be used as the channel's update version number.
95
96           Multiple --channel switches cannot be used with --install.  To
97           install multiple channels from tarballs, run "sa-update" multiple
98           times with different --channel and --install switches, e.g.:
99
100                   sa-update --channel foo.example.com --install foo-34958.tgz
101                   sa-update --channel bar.example.com --install bar-938455.tgz
102
103       --allowplugins
104           Allow downloaded updates to activate plugins.  The default is not
105           to activate plugins; any "loadplugin" or "tryplugin" lines will be
106           commented in the downloaded update rules files.
107
108       --gpg, --nogpg
109           sa-update by default will verify update archives by use of SHA256
110           and SHA512 checksums and GPG signature.  SHA* hashes can verify
111           whether or not the downloaded archive has been corrupted, but it
112           does not offer any form of security regarding whether or not the
113           downloaded archive is legitimate (aka: non-modifed by evildoers).
114           GPG verification of the archive is used to solve that problem.
115
116           If you wish to skip GPG verification, you can use the --nogpg
117           option to disable its use.  Use of the following gpgkey-related
118           options will override --nogpg and keep GPG verification enabled.
119
120           Note: Currently, only GPG itself is supported (ie: not PGP).  v1.2
121           has been tested, although later versions ought to work as well.
122
123       --gpgkey
124           sa-update has the concept of "release trusted" GPG keys.  When an
125           archive is downloaded and the signature verified, sa-update
126           requires that the signature be from one of these "release trusted"
127           keys or else verification fails.  This prevents third parties from
128           manipulating the files on a mirror, for instance, and signing with
129           their own key.
130
131           By default, sa-update trusts key ids "24F434CE" and "5244EC45",
132           which are the standard SpamAssassin release key and its sub-key.
133           Use this option to trust additional keys.  See the --import option
134           for how to add keys to sa-update's keyring.  For sa-update to use a
135           key it must be in sa-update's keyring and trusted.
136
137           For multiple keys, use the option multiple times.  i.e.:
138
139                   sa-update --gpgkey E580B363 --gpgkey 298BC7D0
140
141           Note: use of this option automatically enables GPG verification.
142
143       --gpgkeyfile
144           Similar to the --gpgkey option, except specify the additional keys
145           in a file instead of on the commandline.  This is extremely useful
146           when there are a lot of additional keys that you wish to trust.
147
148       --gpghomedir
149           Specify a directory path to use as a storage area for the
150           "sa-update" GPG keyring.  By default, this is
151
152                   /etc/mail/spamassassin/sa-update-keys
153
154       --import
155           Use to import GPG key(s) from a file into the sa-update keyring
156           which is located in the directory specified by --gpghomedir.
157           Before using channels from third party sources, you should use this
158           option to import the GPG key(s) used by those channels.  You must
159           still use the --gpgkey or --gpgkeyfile options above to get sa-
160           update to trust imported keys.
161
162           To import multiple keys, use the option multiple times.  i.e.:
163
164                   sa-update --import channel1-GPG.KEY --import channel2-GPG.KEY
165
166           Note: use of this option automatically enables GPG verification.
167
168       --refreshmirrors
169           Force the list of sa-update mirrors for each channel, stored in the
170           MIRRORED.BY file, to be updated.  By default, the MIRRORED.BY file
171           will be cached for up to 7 days after each time it is downloaded.
172
173       --updatedir
174           By default, "sa-update" will use the system-wide rules update
175           directory:
176
177                   /var/lib/spamassassin/3.004002
178
179           If the updates should be stored in another location, specify it
180           here.
181
182           Note that use of this option is not recommended; if you're just
183           using sa-update to download updated rulesets for a scanner, and sa-
184           update is placing updates in the wrong directory, you probably need
185           to rebuild SpamAssassin with different "Makefile.PL" arguments,
186           instead of overriding sa-update's runtime behaviour.
187
188       -D [area,...], --debug [area,...]
189           Produce debugging output.  If no areas are listed, all debugging
190           information is printed.  Diagnostic output can also be enabled for
191           each area individually; area is the area of the code to instrument.
192           For example, to produce diagnostic output on channel, gpg, and
193           http, use:
194
195                   sa-update -D channel,gpg,http
196
197           For more information about which areas (also known as channels) are
198           available, please see the documentation at
199           <http://wiki.apache.org/spamassassin/DebugChannels>.
200
201       -h, --help
202           Print help message and exit.
203
204       -V, --version
205           Print sa-update version and exit.
206

EXIT CODES

208       In absence of a --checkonly option, an exit code of 0 means: an update
209       was available, and was downloaded and installed successfully.  If
210       --checkonly was specified, an exit code of 0 means: an update was
211       available.
212
213       An exit code of 1 means no fresh updates were available.
214
215       An exit code of 2 means that at least one update is available but that
216       a lint check of the site pre files failed.  The site pre files must
217       pass a lint check before any updates are attempted.
218
219       An exit code of 3 means that at least one update succeeded while other
220       channels failed.  If using sa-compile, you should proceed with it.
221
222       An exit code of 4 or higher, indicates that errors occurred while
223       attempting to download and extract updates, and no channels were
224       updated.
