Debian DHCP服務器默認情況下不進行客戶端認證,但可以通過安裝和配置DHCP認證工具來實現。具體步驟如下:

  1. 安裝DHCP認證工具:
sudo apt-get update
sudo apt-get install dhcpd-server
  1. 編輯DHCP配置文件(通常位于 /etc/dhcp/dhcpd.conf ),在配置文件中添加以下內容,以啟用客戶端認證:
require client-authentication;
  1. 為需要認證的客戶端創建一個OU(組織單元)和相應的用戶類。例如,在 /etc/dhcp/dhcpd.conf 中添加以下內容:
class "authenticated" {
    match if { is_authenticated(client); };
    # Add other options for authenticated clients here
}
  1. 創建一個腳本 /etc/dhcp/auth-users ,用于驗證客戶端的用戶名和密碼。例如:
#!/bin/sh
# Replace these variables with your own credentials
USERNAME "myuser"
PASSWORD "mypassword"

# Read the client's username and password from stdin
read -s client_username
read -s client_password

# Verify the credentials
if [ "$client_username" = "$USERNAME" ] && [ "$client_password" = "$PASSWORD" ]; then
    echo "Authenticated client: $client_username"
    exit 0
else
    echo "Authentication failed for client: $client_username"
    exit 1
fi
  1. 使腳本可執行:
sudo chmod +x /etc/dhcp/auth-users
  1. 重啟DHCP服務器以應用更改:
sudo systemctl restart dhcpd
