sxid - check for changes in s[ug]id files and directories
sxid [ --config <file> ] [ --nomail ] [ --spotcheck ] [ --listall ]
Sxid checks for changes in suid and sgid files and directories based on
its last check. Logs are stored by default in /var/log/sxid.log. The
changes are then emailed to the address specified in the configuration
file. The default location for the config file is /etc/sxid.conf but
this can be overridden with the --config option and specifying an
The program outputs several different checks concerning the current
status of the suid and sgid files and directories on the system on
which it was run. This is a basic overview of the format.
In the add remove section, new files are preceded by a ’+’, old ones
are preceded by a ’-’ NOTE: that removed does not mean gone from the
filesystem, just that it is no longer sgid or suid.
Most of it is pretty easy to understand. On the sections that show
changes in the file’s info (uid, gid, modes...) the format is old->new.
So if the old owner was ’mail’ and it is now ’root’ then it shows it as
The list of files in the checks is in the following format:
/full/path *user.group MODE
(MODE is the 4 digit mode, as in 4755)
In the changes section, if the line is preceded by an ’i’ then that
item has changed inodes since the last check (regardless of any s[ug]id
change), if there is an ’m’ then the md5sum has changed.
If a user or group entry is preceded by a ’*’ then it’s execution bit
is set (ie. *root.wheel is suid, root.*wheel is sgid, *root.*wheel is
On the forbidden directories, if ENFORCE is enabled an ’r’ will precede
forbidden items that were succesfully -s’d, and an ’!’ will show that
it was unsuccesfully -s’d (for what ever reason).
-c, --config <file>

sends output to stdout instead of emailing, useful for spot
Checks for changes by recursing the current working directory.
Log files will not be rotated and no email sent. All output will
go to stdout.
Useful when doing --spotcheck or --nomail to list all files that
are logged, regardless of changes.
