/etc/ssh路径下创建sshrc文件

#!/bin/bash
user=$USER
ip=${SSH_CLIENT%% *}
hostname=$(hostname)

# 调用告警脚本
/root/anaconda3/bin/python3 /etc/ssh/SendMsg.py   "$user" "$ip" "$hostname"

Python脚本

import time
import requests
import json
import sys

# 钉钉token
token = "21c469xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
