Welche Option in der sshd-Konfigurationsdatei weist sshd an, nur bestimmten Benutzernamen die Anmeldung an einem System zu erlauben?
(Geben Sie NUR den Optionsnamen ohne Werte an.)
Correct Answer:
AllowUsers
Explanation:
The option in the sshd configuration file that instructs sshd to permit only specific user names to log in to a system is AllowUsers.
This option can be followed by a list of user name patterns, separated by spaces, that are allowed to log in.
For example:
AllowUsers alice bob
This will allow only alice and bob to log in via ssh. Any other user will be denied access. The AllowUsers option can also take the form USER@HOST to restrict logins to particular users from particular hosts. For example:
AllowUsers [email protected].* [email protected]
This will allow alice to log in from any host in the 192.168.1.0/24 network, and bob to log in from the host example.com. The AllowUsers option can be used in conjunction with the DenyUsers option, which does the opposite. The allow/deny directives are processed in the following order: DenyUsers, AllowUsers, DenyGroups, and finally AllowGroups.
