The default channel is \&\fIupdates.spamassassin.org\fR, which has updated rules since the previous release. .PP Update archives are verified using \s-1GPG\s0 signatures by default. If \s-1GPG\s0 is disabled (not recommended), file integrity is checked with \s-1SHA512\s0 or \s-1SHA256\s0 checksums. .PP Note that \f(CW\*(C`sa\-update\*(C'\fR will not restart \f(CW\*(C`spamd\*(C'\fR or otherwise cause a scanner to reload the now-updated ruleset automatically. Instead, \&\f(CW\*(C`sa\-update\*(C'\fR is typically used in something like the following manner: .PP .Vb 1 \& sa\-update && /etc/init.d/spamassassin reload .Ve .PP This works because \f(CW\*(C`sa\-update\*(C'\fR only returns an exit status of \f(CW0\fR if it has successfully downloaded and installed an updated ruleset. .PP The program sa-update uses the underlying operating system umask for the updated rule files it installs. You may wish to run sa-update from a script that sets the umask prior to calling sa-update. For example: .PP .Vb 3 \& #!/bin/sh \& umask 022 \& sa\-update .Ve .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-\-channel\fR" 4 .IX Item "--channel" sa-update can update multiple channels at the same time. By default, it will only access \*(L"updates.spamassassin.org\*(R", 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.: .Sp .Vb 1 \& sa\-update \-\-channel foo.example.com \-\-channel bar.example.com .Ve .IP "\fB\-\-channelfile\fR" 4 .IX Item "--channelfile" Similar to the \fB\-\-channel\fR 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. .IP "\fB\-\-checkonly\fR" 4 .IX Item "--checkonly" Only check if an update is available, don't actually download and install it. The exit code will be \f(CW0\fR or \f(CW1\fR as described below. .IP "\fB\-\-install\fR" 4 .IX Item "--install" Install updates \*(L"offline\*(R", from the named tar.gz file, instead of performing \&\s-1DNS\s0 lookups and \s-1HTTP\s0 invocations. .Sp Files named \fBfile\fR.asc, \fBfile\fR.sha512, or \fBfile\fR.sha256 will be used for \&\s-1GPG\s0 signature, and the \s-1SHA256\s0 and \s-1SHA512\s0 checksums, respectively. The filename provided must contain a version number of at least 3 digits, which will be used as the channel's update version number. .Sp Multiple \fB\-\-channel\fR switches cannot be used with \fB\-\-install\fR. To install multiple channels from tarballs, run \f(CW\*(C`sa\-update\*(C'\fR multiple times with different \&\fB\-\-channel\fR and \fB\-\-install\fR switches, e.g.: .Sp .Vb 2 \& sa\-update \-\-channel foo.example.com \-\-install foo\-34958.tgz \& sa\-update \-\-channel bar.example.com \-\-install bar\-938455.tgz .Ve .IP "\fB\-\-allowplugins\fR" 4 .IX Item "--allowplugins" Allow downloaded updates to activate plugins. The default is not to activate plugins; any \f(CW\*(C`loadplugin\*(C'\fR or \f(CW\*(C`tryplugin\*(C'\fR lines will be commented in the downloaded update rules files. .Sp You should never enable this for 3rd party update channels, since plugins can execute unrestricted code on your system, even possibly as root! This includes spamassassin official updates, which have no need to include running code. .Sp Use \-\-reallyallowplugins option to bypass warnings and make it work. .IP "\fB\-\-gpg\fR, \fB\-\-nogpg\fR" 4 .IX Item "--gpg, --nogpg" sa-update by default will verify update archives by use of \s-1GPG\s0 signature. .Sp If you wish to skip \s-1GPG\s0 verification (very unsafe), you can use the \&\fB\-\-nogpg\fR option to disable its use. Use of the following gpgkey-related options will override \fB\-\-nogpg\fR and keep \s-1GPG\s0 verification enabled. .Sp If \s-1GPG\s0 is disabled, only \s-1SHA512\s0 or \s-1SHA256\s0 checksums are used to 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). .Sp Note: Only GnuPG is supported (ie: not any other \s-1PGP\s0 software). .IP "\fB\-\-gpgkey\fR" 4 .IX Item "--gpgkey" sa-update has the concept of \*(L"release trusted\*(R" \s-1GPG\s0 keys. When an archive is downloaded and the signature verified, sa-update requires that the signature be from one of these \*(L"release trusted\*(R" keys or else verification fails. This prevents third parties from manipulating the files on a mirror, for instance, and signing with their own key. .Sp By default, sa-update trusts key ids \f(CW\*(C`24F434CE\*(C'\fR and \f(CW\*(C`5244EC45\*(C'\fR, which are the standard SpamAssassin release key and its sub-key. Use this option to trust additional keys. See the \fB\-\-import\fR option for how to add keys to sa-update's keyring. For sa-update to use a key it must be in sa-update's keyring and trusted. .Sp For multiple keys, use the option multiple times. i.e.: .Sp .Vb 1 \& sa\-update \-\-gpgkey E580B363 \-\-gpgkey 298BC7D0 .Ve .Sp Note: use of this option automatically enables \s-1GPG\s0 verification. .IP "\fB\-\-gpgkeyfile\fR" 4 .IX Item "--gpgkeyfile" Similar to the \fB\-\-gpgkey\fR 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. .IP "\fB\-\-gpghomedir\fR" 4 .IX Item "--gpghomedir" Specify a directory path to use as a storage area for the \f(CW\*(C`sa\-update\*(C'\fR \s-1GPG\s0 keyring. By default, this is .Sp .Vb 1 \& /etc/spamassassin/sa\-update\-keys .Ve .IP "\fB\-\-import\fR" 4 .IX Item "--import" Use to import \s-1GPG\s0 key(s) from a file into the sa-update keyring which is located in the directory specified by \fB\-\-gpghomedir\fR. Before using channels from third party sources, you should use this option to import the \s-1GPG\s0 key(s) used by those channels. You must still use the \fB\-\-gpgkey\fR or \fB\-\-gpgkeyfile\fR options above to get sa-update to trust imported keys. .Sp To import multiple keys, use the option multiple times. i.e.: .Sp .Vb 1 \& sa\-update \-\-import channel1\-GPG.KEY \-\-import channel2\-GPG.KEY .Ve .Sp Note: use of this option automatically enables \s-1GPG\s0 verification. .IP "\fB\-\-refreshmirrors\fR" 4 .IX Item "--refreshmirrors" Force the list of sa-update mirrors for each channel, stored in the \s-1MIRRORED.BY\s0 file, to be updated. By default, the \s-1MIRRORED.BY\s0 file will be cached for up to 7 days after each time it is downloaded. .IP "\fB\-\-forcemirror\fR" 4 .IX Item "--forcemirror" Force the download from a specific host instead of relying on mirrors listed in \s-1MIRRORED.BY.\s0 .IP "\fB\-\-updatedir\fR" 4 .IX Item "--updatedir" By default, \f(CW\*(C`sa\-update\*(C'\fR will use the system-wide rules update directory: .Sp .Vb 1 \& /var/lib/spamassassin/4.000000 .Ve .Sp If the updates should be stored in another location, specify it here. .Sp 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 \&\f(CW\*(C`Makefile.PL\*(C'\fR arguments, instead of overriding sa-update's runtime behaviour. .IP "\fB\-D\fR [\fIarea,...\fR], \fB\-\-debug\fR [\fIarea,...\fR]" 4 .IX Item "-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; \&\fIarea\fR is the area of the code to instrument. For example, to produce diagnostic output on channel, gpg, and http, use: .Sp .Vb 1 \& sa\-update \-D channel,gpg,http .Ve .Sp For more information about which areas (also known as channels) are available, please see the documentation at . .IP "\fB\-h\fR, \fB\-\-help\fR" 4 .IX Item "-h, --help" Print help message and exit. .IP "\fB\-V\fR, \fB\-\-version\fR" 4 .IX Item "-V, --version" Print sa-update version and exit. .SH "EXIT CODES" .IX Header "EXIT CODES" In absence of a \-\-checkonly option, an exit code of \f(CW0\fR means: an update was available, and was downloaded and installed successfully. If \-\-checkonly was specified, an exit code of \f(CW0\fR means: an update was available. .PP An exit code of \f(CW1\fR means no fresh updates were available. .PP An exit code of \f(CW2\fR 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. .PP An exit code of \f(CW3\fR means that at least one update succeeded while other channels failed. If using sa-compile, you should proceed with it. .PP An exit code of \f(CW4\fR or higher, indicates that errors occurred while attempting to download and extract updates, and no channels were updated. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBMail::SpamAssassin\fR\|(3) \&\fBMail::SpamAssassin::Conf\fR\|(3) \&\fBspamassassin\fR\|(1) \&\fBspamd\fR\|(1) .SH "PREREQUISITES" .IX Header "PREREQUISITES" \&\f(CW\*(C`Mail::SpamAssassin\*(C'\fR .SH "BUGS" .IX Header "BUGS" See .SH "AUTHORS" .IX Header "AUTHORS" The Apache SpamAssassin(tm) Project .SH "LICENSE AND COPYRIGHT" .IX Header "LICENSE AND COPYRIGHT" SpamAssassin is distributed under the Apache License, Version 2.0, as described in the file \f(CW\*(C`LICENSE\*(C'\fR included with the distribution. .PP Copyright (C) 2015 The Apache Software Foundation
