DESCRIPTION
sa-update automates the process of downloading and installing new rules and configuration, based on
channels. The default channel is updates.spamassassin.org, which has updated rules since the
previous release.
Update archives are verified using SHA1 hashes and GPG signatures, by default.
Note that "sa-update" will not restart "spamd" or otherwise cause a scanner to reload the now-updated
ruleset automatically. Instead, "sa-update" is typically used in something like the following
manner:
sa-update && /etc/init.d/spamassassin reload
This works because "sa-update" only returns an exit status of 0 if it has successfully downloaded and
installed an updated ruleset.
OPTIONS
--channel
sa-update can update multiple channels at the same time. By default, it will only access
"updates.spamassassin.org", but more channels can be specified via this option. If there are
multiple additional channels, use the option multiple times, once per channel. i.e.:
sa-update --channel foo.example.com --channel bar.example.com
--channelfile
Similar to the --channel option, except specify the additional channels in a file instead of on
the commandline. This is useful when there are a lot of additional channels.
--checkonly
Only check if an update is available, don't actually download and install it. The exit code will
be 0 or 1 as described below.
--allowplugins
Allow downloaded updates to activate plugins. The default is not to activate plugins; any
"loadplugin" or "tryplugin" lines will be commented in the downloaded update rules files.
--gpg, --nogpg
sa-update by default will verify update archives by use of a SHA1 checksum and GPG signature.
SHA1 hashes can verify whether or not the downloaded archive has been corrupted, but it does not
offer any form of security regarding whether or not the downloaded archive is legitimate (aka:
non-modifed by evildoers). GPG verification of the archive is used to solve that problem.
If you wish to skip GPG verification, you can use the --nogpg option to disable its use. Use of
the following gpgkey-related options will override --nogpg and keep GPG verification enabled.
Note: Currently, only GPG itself is supported (ie: not PGP). v1.2 has been tested, although
later versions ought to work as well.
--gpgkey
sa-update has the concept of "release trusted" GPG keys. When an archive is downloaded and the
signature verified, sa-update requires that the signature be from one of these "release trusted"
keys or else verification fails. This prevents third parties from manipulating the files on a
mirror, for instance, and signing with their own key.
By default, sa-update trusts key id "265FA05B", which is the standard SpamAssassin release key.
Use this option to trust additional keys. See the --import option for how to add keys to sa-update's saupdate's
update's keyring. For sa-update to use a key it must be in sa-update's keyring and trusted.
For multiple keys, use the option multiple times. i.e.:
sa-update --gpgkey E580B363 --gpgkey 298BC7D0
Note: use of this option automatically enables GPG verification.
--gpgkeyfile
Similar to the --gpgkey option, except specify the additional keys in a file instead of on the
commandline. This is extremely useful when there are a lot of additional keys that you wish to
trust.
--gpghomedir
Specify a directory path to use as a storage area for the "sa-update" GPG keyring. By default,
this is
//etc/mail/spamassassin/sa-update-keys
--import
Use to import GPG key(s) from a file into the sa-update keyring which is located in the directory
specified by --gpghomedir. Before using channels from third party sources, you should use this
option to import the GPG key(s) used by those channels. You must still use the --gpgkey or
--gpgkeyfile options above to get sa-update to trust imported keys.
To import multiple keys, use the option multiple times. i.e.:
sa-update --import channel1-GPG.KEY --import channel2-GPG.KEY
Note: use of this option automatically enables GPG verification.
--updatedir
By default, "sa-update" will use the system-wide rules update directory:
//var/spamassassin/spamassassin/3.002001
If the updates should be stored in another location, specify it here.
Note that use of this option is not recommended; if you're just using sa-update to download
updated rulesets for a scanner, and sa-update is placing updates in the wrong directory, you
probably need to rebuild SpamAssassin with different "Makefile.PL" arguments, instead of
overriding sa-update's runtime behaviour.
-D [area,...], --debug [area,...]
Produce debugging output. If no areas are listed, all debugging information is printed.
Diagnostic output can also be enabled for each area individually; area is the area of the code to
instrument. For example, to produce diagnostic output on channel, gpg, and http, use:
sa-update -D channel,gpg,http
For more information about which areas (also known as channels) are available, please see the
documentation at <http://wiki.apache.org/spamassassin/DebugChannels.
-h, --help
Print help message and exit.
-V, --version
Print sa-update version and exit.
EXIT CODES
An exit code of 0 means an update was available, and was downloaded and installed successfully if
--checkonly was not specified.
An exit code of 1 means no fresh updates were available.
An exit code of 2 means that at least one update is available but that a lint check of the site pre
files failed. The site pre files must pass a lint check before any updates are attempted.
An exit code of 4 or higher, indicates that errors occurred while attempting to download and extract
updates.
