有几台服务器太久没上，而这几台服务器我刚好又配置了 jumpserver，今天用 jumpserver 登录发现有两个文件以前从来没见过，guapan new.sh。其中 guapan 这个文件一打开就崩溃，我下载到本地 win 试着用记事本打开，一打开电脑就超级卡，new.sh cat 后： #!/bin/bash

namelist=$(cat /proc/net/dev | grep -v Inter | grep -v face | awk -F: '{print $1}') MAC=$(ip a | perl -lane 'print /.link/ether\s(\S)\s/' | tail -n 1)

for i in ${namelist}; do if [ -e /etc/sysconfig/network-scripts/ifcfg-${i} ]; then echo "This network config file is exists." else echo "DEVICE=${i}" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "TYPE=Ethernet" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "OnBOOT=yes" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "NM_COnTROLLED=yes" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "BOOTPROTO=static" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "NAME="System ${i}"" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "IPADDR=$1" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "NETMASK=$2" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "GATEWAY=$3" >> /etc/sysconfig/network-scripts/ifcfg-${i} echo "HWADDR=${MAC}" >> /etc/sysconfig/network-scripts/ifcfg-${i} && service network restart fi done

后来我发现 jumpserver 登上去的几台服务器都有这两个文件，该不是被挂上了码吧？
