.SH "NAME"
systraq \- monitors your system and warns you when files change
.SH "SYNOPSIS"
.HP \w'\fBsystraq\fR\ 'u
\fBsystraq\fR
.SH "DESCRIPTION"
.PP
\fBsystraq\fR
is part of the systraq package, a set of scripts that monitors your system for file changes\&. It is meant to be run by a cronjob, not directly\&.
.PP
\fBsystraq\fR
runs various system commands, to inspect the state of the system: what is it doing now?, what has it been doing recently?, are we running to hardware limitations?\&. Furthermore, it runs commands to inspect some files in users\*(Aq homedirectories, as well as some system files, for frequently seen flaws\&. All these commands are maintained in little scripts in
/etc/systraq/systraq\&.d\&. The first two characters of the script\*(Aqs name are used for the execution\-order\&. The names of executable files in systraq\&.d/ (or symlinks to such files) must consist entirely of upper and lower case letters, digits, underscores, and hyphens\&. Files which not adhere will be silently ignored\&. The systraq script supplies some environment variables to the scripts in
systraq\&.d/, these might be helpful when adding your own scripts\&. Refer to the (very small)
\fBsystraq\fR
code itself for the details\&.
.PP
We\*(Aqll elaborate on some of the shipped
systraq\&.d/
scripts\&.
.PP
\fB\fIAA\fR\fR\fB\-shellrc\fR
checks for unsafe umask setting in shell startup scripts, or unsafe PATH in these scripts\&.
.PP
\fB\fIAA\fR\fR\fB\-debsums\fR
runs
\fBdebsums\fR, to check md5sums as stated in packaging files with the sums of the actual files running the system\&. (NB: debsums has support for md5 checksums only, most Debian packages ship md5 checksums only\&. Therefore, we can\*(Aqt use sha256sum\&. See also the discussion on
\m[blue]\fBproposed release goal: DEBIAN/md5sums for all packages\fR\m[]\&\s-2\u[1]\d\s+2
at the Debian release mailinglist in August 2007 as well as
\m[blue]\fBDebian Bug #268658\fR\m[]\&\s-2\u[2]\d\s+2
for some considerations on this\&.)
.PP
\fB\fIAA\fR\fR\fB\-localdigest\fR
runs
\fBsha256sum\fR
(or the command set in the ST_SUM environment variable) to check message digests as locally maintained in a file named in the ST_LDIGESTS environment variable\&. Typically, this is set to
/var/lib/systraq/systraq\&.sums\&. If this environment variable is unset, this check is silenty skipped\&.
.PP
Of course, you can add your own scripts\&. If you name them
\fB\fIAA\fR\fR\fB\-local\fR, they\*(Aqll never get overwritten by any version of this software\&. If you don\*(Aqt like one of these scripts, you can disable it by removing the symlink, and creating a new symlink with the same name pointing to
\fB/bin/true\fR\&.
