正確答案:
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.

正確答案:
nfsstat
Explanation:
The command that displays NFS kernel statistics is nfsstat. This command can be used to show information about the number and type of NFS and RPC calls made by the NFS client or server. It can also be used to reset the statistics to zero, or to display information about mounted NFS file systems. The nfsstat command is part of the nfs-utils package and can be installed on most Linux distributions. For more information about the nfsstat command, you can refer to the following resources:
1: A Microsoft Learn article that explains the syntax and usage of the nfsstat command on Windows Server.
2: A Bing search result page that shows various links and snippets related to the nfsstat command.
3: A Red Hat article that demonstrates how to use the nfsstat and nfsiostat commands to troubleshoot NFS performance issues on Linux.
