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

}这里有常用的域名网站的折扣码：
在国内86手机号有概率性的收不到tg验证码短信，tg有Login Email功能，但似乎只在内测，没有全部放开，这也催生了很多卖Login Email功能号的生意，既然有人干这门生意，那就说明有门道能开通，经过尝试如下方法可行，现分享：
Setting - Ask a Question - Ask a Volunteer根据提示，用英文留言希望能支持开通，没有回复，但过一两天后Logout再Login就成了
就是先用tg登录，再用tgx不停的登录退出，只选择用短信收接验证码登录，个人没有尝试过，按理论上存在一定的风险，仅供参考:
