IP归属地查询

有一些网站提供免费的API，可以批量查询给定IP的归属地。以下是一些常用的免费IP地理位置API：

  1. IPinfo.io 推荐:

    • 官网: ipinfo.io
    • 免费套餐每月允许多达 50,000 次请求。
    • API调用示例: http://ipinfo.io/8.8.8.8?token=$TOKEN
    • 需要注册获取API密钥。

  2. ipstack 不推荐:

    • 官网: ipstack.com
    • 免费套餐每月允许 100 次请求。
    • API调用示例: http://api.ipstack.com/{IP}?access_key=YOUR_ACCESS_KEY
    • 需要注册获取API密钥。

  3. IPgeolocation.io 推荐:

    • 官网: ipgeolocation.io
    • 免费套餐每天允许 1000 次请求，每月30K次。
    • API调用示例: https://api.ipgeolocation.io/ipgeo?apiKey=YOUR_API_KEY&ip={IP}
    • 需要注册获取API密钥。

  4. ipapi 不推荐:

    • 官网: ipapi.com
    • 免费套餐每月允许 100 次请求。
    • API调用示例: http://api.ipapi.com/{IP}?access_key=YOUR_ACCESS_KEY
    • 需要注册获取API密钥。

  5. IP2Location 推荐:

    • 官网: ip2location.com
    • 免费试用版本每月允许 30K 次查询。
    • API调用示例: https://api.ip2location.io/?key={YOUR_API_KEY}&ip=8.8.8.8&format=json
    • 需要注册获取API密钥。

这些API服务通常都提供一定数量的免费查询额度，可以满足一些基本的需求。如果需要进行大量查询，可能需要考虑付费版本。建议在选择之前详细阅读每个服务的免费套餐条款，以确定其是否满足您的需求。

受CVE-2024-6387漏洞影响，各大版本的openssh基本上都要更新（这个漏洞存在于 OpenSSH < 4.4p1 或 8.5p1 <= OpenSSH < 9.8p1 的版本中），目前各大版本也都发布了安全更新，debian/ubuntu系升级主要两条指令：

sudo apt update
sudo apt install --only-upgrade openssh-server

升级后，确认一下版本：

ssh -V

  • debian:

    bullseye (security), bullseye    1:8.4p1-5+deb11u3
  bookworm (security)    1:9.2p1-2+deb12u3
               sid    1:9.7p1-7

  • ubuntu:

    jammy    Released (1:8.9p1-3ubuntu0.10)
mantic    Released (1:9.3p1-1ubuntu3.6)
noble    Released (1:9.6p1-3ubuntu13.3)

常用的标准Linux环境里都有Systemd提供后台服务进程管理及保活，但是在一些特殊的运行环境还是需要简易的解决方案。

比如在serv00服务器freeBSD Linux环境下，可以写这个这样的脚本：

check_and_start_process.sh

#!/bin/bash

# Define process name and start command
PROCESS_NAME="command"
START_COMMAND="/path/to/your/command"

# Check if the process is running
if ! pgrep -f "$PROCESS_NAME" > /dev/null
then
    echo "Process $PROCESS_NAME is not running, starting it now..."
    # Start the process
    $START_COMMAND &
    if [ $? -eq 0 ]; then
        echo "Process $PROCESS_NAME started successfully."
    else
        echo "Failed to start process $PROCESS_NAME."
    fi
else
    echo "Process $PROCESS_NAME is already running."
fi

修改脚本中的PROCESS_NAME和START_COMMAND值，并增加运行权限：

chmod +x check_and_start_process.sh

接着添加定时任务：

crontab -e

每5分钟检测一次：

*/5 * * * * /path/to/check_and_start_process.sh

提示
在serv00服务器中，定时任务执行后如果会触发email，则改用：

*/5 * * * * /path/to/check_and_start_process.sh > /dev/null 2>&1

参考网上资料梳理的Cloudflare IP地址归属地信息，具体准确性待考证：
