Welche Datei muss, falls vorhanden, alle Benutzer enthalten, die das Cron-Planungssystem verwenden dürfen? (Geben Sie den vollständigen Namen der Datei einschließlich Pfad an.)
正解:
crontab
Explanation:
The file /etc/cron.allow, if present, must contain all users that are allowed to use the cron scheduling system. This file is used to restrict the access to cron for security reasons. Only users listed in this file can create and edit their own crontab files using the crontab command. If the file does not exist, all users can use cron, unless the file /etc/cron.deny exists, which lists the users that are not allowed to use cron12. Reference: 1: Cron and Crontab usage and examples. 2: How to use cron in Linux.

Welcher Parameter muss an ifconfig übergeben werden, um eine zuvor inaktive Netzwerkschnittstelle zu aktivieren? (Geben Sie den Parameter nur ohne Befehl, Pfad oder zusätzliche Optionen an.)
正解:
up
Explanation:
The parameter that must be passed to ifconfig to activate a previously inactive network interface is up. The up parameter tells the kernel to activate the network interface and allow it to send and receive packets. The opposite of up is down, which deactivates the network interface. The up parameter is part of the topic 109.2: Basic network configuration, which is one of the objectives of the LPI Linux Administrator - 102 exam12.

Welches Attribut gibt in einer xinetd-Konfigurationsdatei die Netzwerkadresse an, die zur Bereitstellung des Dienstes verwendet wird?
正解:
bindinterface
Explanation:
The bind attribute in an xinetd configuration file specifies the network address that will be used to provide the service. It can be either an IP address or a hostname. If the bind attribute is not specified, xinetd will listen on all available addresses on the system. The bind attribute can be used to restrict the service to a specific interface or network. For example, bind = 192.168.1.100 will only allow the service to be accessed from the 192.168.1.0/24 network. The bind attribute can also be used to provide different configurations for the same service on different addresses. For example, one can have two telnet configuration files, one with bind = 192.168.1.100 and another with bind = 192.168.2.100, to offer different access rules or options for the telnet service on each address.
