=== OPTIONS ===
=== OPTIONS ===
'''rkhunter''' uses a configuration file, named   ''rkhunter.conf'', for many of its configuration options. It can also use   a local configuration file, named ''rkhunter.conf.local'', and a   directory named ''rkhunter.d'' if it is present. Both the local   configuration file, and the local directory, must be in the same directory   as the main configuration file. The installer does not create the local file   or directory, but one, or both, can be created by the user if required. If a   directory is used, then within the directory any file ending in ''.conf''   will be treated as a local configuration file.

Some options can also be specified on the command-line, and these   will override the equivalent configuration file options. The configuration   file options are well documented within the main configuration file itself.   The following are the command-line options. The defaults mentioned here are   the program defaults, unless explicitly stated as the configuration file   default.

; '''--bindir <directory>...'''
: This option modifies which directories '''rkhunter''' looks in to find     the various commands it requires (that is, its PATH). The default is the     root PATH, and an internal list of some common command directories. By     default a specified directory will be appended to the default list.     However, if the directory name begins with the '+' character, then it will     be prepended to the list (that is, it will be put at the start of the     list).

rkhunter - RootKit Hunter

Beschreibung

rkhunter ist ein Shell-Skript, das verschiedene Überprüfungen auf dem lokalen System durchführt, um bekannte Rootkits und Malware zu erkennen.

  • Es überprüft auch, ob Befehle oder die Systemstartdateien verändert wurden, und führt verschiedene Überprüfungen der Netzwerkschnittstellen durch, einschließlich der Überprüfung auf lauschende Anwendungen.

rkhunter wurde so generisch wie möglich geschrieben und sollte daher auf den meisten Linux- und UNIX-Systemen laufen.

  • Es wird mit einigen Support-Skripten geliefert, falls bestimmte Befehle im System fehlen sollten, von denen einige Perl-Skripte sind.
  • rkhunter benötigt bestimmte Befehle, um ausgeführt werden zu können.
  • Darüber hinaus erfordern einige Tests bestimmte Befehle, aber wenn diese nicht vorhanden sind, wird der Test übersprungen.
  • rkhunter muss unter einer Bourne-artigen Shell ausgeführt werden, in der Regel bash oder ksh.
  • rkhunter kann als Cron-Job oder über die Befehlszeile ausgeführt werden.
LIZENZ

RootKit Hunter ist unter der GPL lizenziert

  • Copyright Michael Boelen
  • Einzelheiten zur GPL-Lizenzierung finden Sie in der Datei LICENSE.

Installation

sudo apt install rkhunter

Aufruf

 rkhunter {--check | --unlock | --update | --versioncheck | --propupd [{filename | directory | package name},...] | --list [tests | {lang | languages} | rootkits | perl | propfiles] | --config-check | --version | --help} [options]

Optionen

Unix GNU Parameter Beschreibung


BEFEHLSOPTIONEN

Wenn keine Befehlsoption angegeben wird, wird --help angenommen. rkhunter gibt einen Exit-Code ungleich Null zurück, wenn ein Fehler oder eine Warnung auftritt.

Option Beschreibung
-c, --check Diese Befehlsoption weist rkhunter an, verschiedene Überprüfungen auf dem lokalen System durchzuführen. Das Ergebnis jedes Tests wird auf stdout angezeigt. Wenn

etwas Verdächtiges gefunden wird, wird eine Warnung angezeigt. Eine Protokolldatei der Tests und der Ergebnisse wird automatisch erstellt.

Es wird empfohlen, diese Befehlsoption regelmäßig auszuführen, um sicherzustellen, dass das System nicht kompromittiert wurde.

--unlock Diese Befehlsoption entsperrt (entfernt) einfach die Sperrdatei. Wenn diese Option allein verwendet wird, wird keine Protokolldatei erstellt.
--update Diese Befehlsoption veranlasst rkhunter zu überprüfen, ob es eine neuere Version einer seiner Textdatendateien gibt. Ein Befehlszeilen-Webbrowser, zum

Beispiel wget oder linux, muss auf dem System vorhanden sein, wenn diese Option verwendet wird.

Es wird empfohlen, diese Befehlsoption regelmäßig auszuführen, um sicherzustellen, dass die Datendateien auf dem neuesten Stand sind.

Wenn diese Option über cron verwendet wird, wird empfohlen, auch die Option --nocolors zu verwenden.

Ein Exit-Code von Null für diese Befehlsoption bedeutet, dass keine Updates verfügbar waren. Ein Exit-Code von eins bedeutet, dass ein Download-Fehler aufgetreten ist, und ein Code von zwei bedeutet, dass kein Fehler aufgetreten ist, aber Updates verfügbar waren und installiert wurden.

Verzeichnis | Paketname},...] Eine der Überprüfungen, die rkhunter durchführt, ist der Vergleich verschiedener aktueller Dateieigenschaften verschiedener Befehle mit denen, die zuvor

gespeichert wurden. Diese Befehlsoption bewirkt, dass rkhunter seine Datendatei mit gespeicherten Werten mit den aktuellen Werten aktualisiert.

Wenn die Option „filename“ verwendet wird, muss es sich entweder um einen vollständigen Pfadnamen oder um einen einfachen Dateinamen (z. B. „awk“) handeln. Bei Verwendung wird nur der Eintrag in der Dateieigenschaftsdatenbank für diese Datei aktualisiert. Wenn die Option directory verwendet wird, werden nur die in der Datenbank aufgeführten Dateien aktualisiert, die sich in dem angegebenen Verzeichnis befinden. Wenn die Option package name verwendet wird, werden ebenfalls nur die Dateien in der Datenbank aktualisiert, die Teil des angegebenen Pakets sind. Der Paketname muss der Basisteil des Namens sein, Versionsnummern sollten nicht enthalten sein – zum Beispiel „coreutils”. Paketnamen werden natürlich nur dann in der Dateieigenschaftsdatenbank gespeichert, wenn ein Paketmanager verwendet wird. Wenn ein Paketname mit einem Dateinamen übereinstimmt – beispielsweise könnte „file” sich auf den Befehl „file” oder auf das RPM -Paket „file” (das den Befehl „file” enthält) beziehen –, wird der Paketname verwendet. Wenn keine bestimmte Option angegeben wird, wird die gesamte Datenbank aktualisiert.

WARNUNG: Es liegt in der Verantwortung des Benutzers, sicherzustellen, dass die Dateien auf dem System echt sind und aus einer zuverlässigen Quelle stammen. rkhunter kann nur melden, ob sich eine Datei geändert hat, aber nicht, was die Änderung verursacht hat. Wenn sich also eine Datei geändert hat und die Befehlsoption --propupd verwendet wird, geht rkhunter davon aus, dass die Datei echt ist.

--versioncheck Diese Befehlsoption veranlasst rkhunter zu überprüfen, ob eine neuere Version des Programms verfügbar ist. Bei Verwendung dieser Option muss ein Befehlszeilen-Webbrowser auf dem

System vorhanden sein.

Wenn diese Option über cron verwendet wird, wird empfohlen, auch die Option --nocolors zu verwenden.

Ein Exit-Code von Null für diese Befehlsoption bedeutet, dass keine neue Version verfügbar war. Ein Exit-Code von eins bedeutet, dass beim Herunterladen der neuesten Versionsnummer ein Fehler aufgetreten ist , und ein Code von zwei bedeutet, dass kein Fehler aufgetreten ist, aber eine neue Version verfügbar ist.

{lang | languages} | rootkits | perl | propfiles] Diese Befehlsoption listet einige der unterstützten Funktionen des Programms auf und beendet dann die Ausführung. Die Option tests listet die derzeit

verfügbaren Testnamen auf (weitere Informationen zu den Testnamen finden Sie in der README-Datei). Die Option languages listet die derzeit verfügbaren Sprachen auf, und die Option rootkits listet die Rootkits auf, nach denen rkhunter sucht. Die Option perl listet den Installationsstatus des Befehls perl und der Perl-Module auf, die von einigen der Tests verwendet werden können. Beachten Sie, dass die Installation dieser Module nicht erforderlich ist. Wenn rkhunter jedoch gezwungen ist, Perl zur Ausführung eines Tests zu verwenden, muss das Modul vorhanden sein. Die Option propfiles listet die Dateinamen auf, die zur Erstellung der Dateieigenschaftsdatenbank verwendet werden. Wenn keine bestimmte Option angegeben wird, werden alle Listen mit Ausnahme der Dateieigenschaftsdatenbank angezeigt.

-C, --config-check Diese Befehlsoption bewirkt, dass rkhunter seine Konfigurationsdatei(en) überprüft und dann beendet wird. Das Programm führt seine normalen Konfigurationsprüfungen

durch, wie sie durch die Optionen enable und disable in der Befehlszeile und in den Konfigurationsdateien festgelegt sind. Das heißt, es werden nur die Konfigurationsoptionen für Tests überprüft, die normalerweise ausgeführt würden. Um alle konfigurierten Optionen zu überprüfen, verwenden Sie die Optionen --enable all --disable none in der Befehlszeile. Zusätzlich überprüft das Programm, ob es nicht erkannte Konfigurationsoptionen gibt. Wenn Konfigurationsprobleme gefunden werden, werden diese angezeigt und der Rückgabecode wird auf 1 gesetzt.

Es wird empfohlen, diese Option immer dann zu verwenden, wenn die Konfigurationsdatei(en) geändert wurden.

-V, --version Diese Befehlsoption bewirkt, dass rkhunter seine Versionsnummer anzeigt und dann beendet wird.
-h, --help Diese Befehlsoption zeigt das Hilfemenü an und beendet dann das Programm.

OPTIONS

rkhunter uses a configuration file, named rkhunter.conf, for many of its configuration options. It can also use a local configuration file, named rkhunter.conf.local, and a directory named rkhunter.d if it is present. Both the local configuration file, and the local directory, must be in the same directory as the main configuration file. The installer does not create the local file or directory, but one, or both, can be created by the user if required. If a directory is used, then within the directory any file ending in .conf will be treated as a local configuration file.

Some options can also be specified on the command-line, and these will override the equivalent configuration file options. The configuration file options are well documented within the main configuration file itself. The following are the command-line options. The defaults mentioned here are the program defaults, unless explicitly stated as the configuration file default.

--appendlog
By default a new log file will be created when rkhunter runs, and the previous log file will be renamed by having .old appended to its name. This option tells rkhunter to append to the existing log file. If the log file does not exist, then it will be created.
--bindir <directory>...
This option modifies which directories rkhunter looks in to find the various commands it requires (that is, its PATH). The default is the root PATH, and an internal list of some common command directories. By default a specified directory will be appended to the default list. However, if the directory name begins with the '+' character, then it will be prepended to the list (that is, it will be put at the start of the list).
--cs2, --color-set2
By default rkhunter will display its test results in color. The colors used are green for successful tests, red for failed tests (warnings), and yellow for skipped tests. These colors are visible when a black background is used, but are difficult to see on a white background. This option tells rkhunter to use a different color set which is more suited to a white background.
--configfile <file>
The installation process will automatically tell rkhunter where its configuration file is located. However, if necessary, this option can be used to specify a different pathname. If a local configuration file, or directory, is to be used, then it must reside in the same directory as the configuration file specified by this option.
--cronjob
This is similar to the --check command option, but it disables several of the interactive options. When this option is used --check, --nocolors and --skip-keypress are assumed. By default no output is sent to stdout, so the --report-warnings-only option may be useful with this option.
--dbdir <directory>
The installation process will automatically configure where the data files are stored for rkhunter. However, if necessary, this option can be used to specify a different directory. The directory can be read-only, after installation, provided that neither of the --update or --propupd options are specified, and that the --versioncheck option is not specified if ROTATE_MIRRORS is set to 1 in the configuration file.
--debug
This is a special option mainly for the developers. It produces no output on stdout. Regular logging will continue as per default or as specified by the --logfile option, and the debug output will be in a randomly generated filename which starts with /tmp/rkhunter-debug.
--disable <test>[,<test>...]
This option tells rkhunter not to run the specified tests. Read the README file for more information about test names. By default no tests are disabled.
--display-logfile
This option will cause the logfile to be displayed on the screen once rkhunter has finished.
--enable <test>[,<test>...]
This option tells rkhunter to only run the specified tests. If only one test name, other than all, is given, then the --skip-keypress option is assumed. Read the README file for more information about test names. By default all tests are enabled. All the test names are listed below under TESTS.
--hash {MD5 | SHA1 | SHA224 | SHA256 | SHA384 | SHA512 |
NONE | <command>} Both the file properties check and the --propupd command option will use a hash function to determine a files current hash value. This option tells rkhunter which hash function to use. The MD5 and SHA options will look for the relevant command, and, if not found, a perl support script will then be used to see if a perl module supporting the function has been installed. Alternatively, a specific command may be specified. A value of NONE can be used to indicate that the hash values should not be obtained or used as part of the file properties check. The default is SHA256. Systems using prelinking must use either MD5, SHA1 or NONE.
--lang, --language <language>
This option specifies which language to use for the displayed tests and results. The currently supported languages can be seen by the --list command option. The default is en (English). If a message to be displayed cannot be found in the language file, then the English version will be used. As such, the English language file must always be present. The --update command option will update the language files when new versions are available.
-l, --logfile [file]
By default rkhunter will write out a log file. The default location of the file is /var/log/rkhunter.log. However, this location can be changed by using this option. If /dev/null is specified as the log file, then no log file will be written. If no specific file is given, then the default will be used. By default rkhunter will create a new log file each time it is run. Any previously existing logfile is moved out of the way, and has .old appended to it.
--noappend-log
This option reverts rkhunter to its default behaviour of creating a new log file rather than appending to it.
--nocf
This option is only valid when the command-line --disable option is used. When the --disable option is used, by default, the configuration file option to disable tests is also used to determine which tests to run. If only the --disable option is to be used to determine which tests to run, then --nocf must be given.
--nocolors
This option causes the result of each test to not be displayed in a specific color. The default color, usually the reverse of the background color, will be used (typically this is just black and white).
--nolog
This option tells rkhunter not to write anything to a log file.
--nomow, --no-mail-on-warning
The configuration file has an option which will cause a simple email message to be sent to a user should rkhunter detect any warnings during system checks. This command-line option overrides the configuration file option, and prevents an email message from being sent. The configuration file default is not to email a message.
--ns, --nosummary
When the --check command option is used, by default a short summary of results is displayed at the end. This option prevents the summary from being displayed.
--novl, --no-verbose-logging
During some tests rkhunter will log a lot of information. Use of this option reduces the amount of logging, and so can improve the performance of rkhunter. However, the log file will contain less information should any warnings occur. By default verbose logging is enabled.
--pkgmgr {RPM | DPKG | BSD | BSDng | SOLARIS | NONE}
This option is used during the file properties check or when the --propupd command option is given. It tells rkhunter that the current file property values should be obtained from the relevant package manager. See the README file for more details of this option. The default is NONE, which means not to use a package manager.
-q, --quiet
This option tells rkhunter not to display any output. It can be useful when only the exit code is going to be checked. Other options may be used with this one, to force only specific items to be displayed.
--rwo, --report-warnings-only
This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may be used to force other items of information to be displayed.
--sk, --skip-keypress
When the --check' command option is used, after certain sections of tests, the user will be prompted to press the return key in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed. If this option has not been given, and the user is prompted to press the return key, a single s' character, in upper- or lowercase, may be given followed by the return key. rkhunter will then continue the tests without prompting the user again (as if this option had been given).
--summary
This option will cause the summary of test results to be displayed. This is the default.
--syslog [facility.priority]
When the --check command option is used, this option will cause the start and finish times to be logged to syslog. The default is not to log anything to syslog, but if the option is used, then the default level is authpriv.notice.
--tmpdir <directory>
The installation process will automatically configure where temporary files are to be created. However, if necessary, this option can be used to specify a different directory. The directory must not be a symbolic link, and must be secure (root access only).
--vl, --verbose-logging
This option tells rkhunter that when it runs some tests, it should log as much information as possible. This can be useful when trying to diagnose why a warning has occurred, but it obviously also takes more time. The default is to use verbose logging.
-x, --autox
When this option is used, rkhunter will try and detect if the X Window system is in use. If it is in use, then the second color set will automatically be used (see the --color-set2 option). This allows rkhunter to be run on, for example, a server console (where X is not present, so the default color set should be used), and on a users terminal (where X is in use, so the second color set should be used). In both cases rkhunter will use the correct color set. The configuration file default is to try and detect X.
-X, --no-autox
This option prevents rkhunter from automatically detecting if the X Window system is being used. See the --autox option.
