NTP 服务器信息

NTP_SERVER="192.168.42.12"

PASSWORD="123456"

多个 IP 地址

HOSTS=("192.168.42.8" "192.168.42.9" "192.168.42.10" "192.168.42.11" "192.168.42.12" "192.168.42.13" "192.168.42.14" "192.168.42.15" "192.168.42.16" "192.168.42.17" "192.168.42.18" "192.168.42.20" "192.168.42.21" "192.168.42.22" "192.168.42.23" "192.168.42.58" "192.168.42.59" "192.168.42.60" "192.168.42.48" "192.168.42.49" "192.168.42.50" "192.168.42.51" "192.168.42.52" "192.168.42.53" "192.168.42.54" "192.168.42.55" "192.168.42.57" "192.168.42.57")

红色和正常颜色的ANSI转义码

RED="\033[31m"

NC="\033[0m" # 用于重置颜色

循环处理每个 IP 地址

for HOST in "${HOSTS $@$ }"

do

执行 SSH 命令并提取关键信息

OUTPUT= $(sshpass -p "$ PASSWORD" ssh -o StrictHostKeyChecking=no root@ $HOST "ntpdate$ NTP_SERVER" 2>/dev/null)

提取时间偏移信息

OFFSET= $(echo "$ OUTPUT" | awk '/adjust time server/ {print $9,$ 10}' | cut -d ' ' -f 1)

判断偏移量是否大于等于 2，并显示红色

if (( $(echo "$ OFFSET >= 2" | bc -l) )); then

输出红色

echo -e " ${RED}$ HOST $NTP_SERVER$ OFFSET${NC}"

else

正常输出

echo " $HOST$ NTP_SERVER $OFFSET"

fi

done
