更新主程序，由于不能跨越多个版本升级，可能需要执行多次。

chown -R www-data /home/nextcloud/cloud/
sudo -E -u www-data php /home/nextcloud/cloud/updater/updater.phar 
#无需确认自动更新
sudo -E -u www-data php /home/nextcloud/cloud/updater/updater.phar --no-interaction

上面更新时会自动更新插件，如需更新插件，注意配置文件不要禁用app市场。

#如果手动更新最后没有关闭维护模式需先关闭
cd /home/nextcloud/cloud/
sudo -E -u www-data php occ maintenance:mode --off  
sudo -E -u www-data php occ app:update --all
sudo -E -u www-data php occ app:update spreed

修改最小权限：

chown -R root:root /home/nextcloud/cloud/
chown www-data /home/nextcloud/cloud/apps/
chown -R www-data /home/nextcloud/cloud/config/
chown -R www-data /home/nextcloud/cloud/data/

无误后删除备份文件：

/home/nextcloud/cloud/data/updater-*

timedatectl set-local-rtc 0

initramfs-tools自带的dhcp有时不能获取到ip，修改使用udhcpc配置dhcp，先禁用自带的网络配置：

sed -i -e '/configure_networking\(\)/{n; a\' -e 'return 0' -e '}' /usr/share/initramfs-tools/scripts/functions

初始化时启动udhcpc：

cat << EOF > /usr/share/initramfs-tools/scripts/init-premount/00-network
#!/bin/sh
PREREQ=""

prereqs() {
  echo "$PREREQ"
}

case "$1" in
  prereqs)
    prereqs
    exit 0
    ;;
esac

interface=eth0
ip link set dev $interface up
udhcpc -i $interface -q -n -t 5 -T 5 -A 30 -b -s /scripts/udhcpc.script

exit 0
EOF
chmod +x /usr/share/initramfs-tools/scripts/init-premount/00-network

udhcpc调用的ip配置脚本：

cat << EOF > /etc/initramfs-tools/scripts/udhcpc.script 
#!/bin/sh

case "$1" in
  BOUND|bound|RENEW|renew)
        # 配置网卡
        ip addr flush dev $interface
        ip addr add $ip/$mask dev $interface
        ip link set dev $interface up

        # 配置默认路由
        ip route del default 2>/dev/null
        if [ -n "$router" ]; then
          for gw in $router; do
            ip route add default via $gw dev $interface
          done
        fi

        # 配置 DNS
        if [ -n "$dns" ]; then
          for ns in $dns; do
            echo "nameserver $ns" >> /etc/resolv.conf
          done
        fi

        ;;
esac

exit 0
EOF
chmod +x /etc/initramfs-tools/scripts/udhcpc.script 

update-initramfs -u -k all

bind包含queryperf的最后版本是9.13.2，也可使用后续独立版本dnsperf

wget https://downloads.isc.org/isc/bind9/9.13.2/bind-9.13.2.tar.gz
tar zxf bind-9.13.2.tar.gz
cd bind-9.13.2/contrib/queryperf
./configure && make
cp queryperf /usr/local/bin/

批量生成一些域名：

#!/usr/bin/env python3

def generate_query_file(filename, num_entries, base_domain="qq.com"):
    with open(filename, 'w') as f:
        for i in range(num_entries):
            f.write(f"{base_domain} A\n")

if __name__ == "__main__":
    generate_query_file("qq_com.txt", 1000000)
    print("测试文件生成完成！")

测试：

queryperf -d qq_com.txt -s 192.168.1.1 -p 53 -l 600

升级到sandboxie plus v1.16.2或修改firefox首选项：

widget.windows.fullscreen_marking_method=2
