Linux/Cygwin助手函数:findremoteip,根据网络连接信息过滤查找特定远程IP,查询和终止Windows相关进程
本函数Cygwin下测试通过,MSYS2,WSL1理论上可用(另:WSL2自然是不行),未经过测试!
findremoteip函数代码:
findremoteip() {
# 根据网络连接的远程主机IP查找Windows相关进程:
# 目前仅针对IPv4做适配,IPv6暂不考虑
if [ -z "$1" ]
then
echo -e "缺少远程IP!"
echo -e "\`findremoteip\` 查看连接到指定IP的相关进程:\n"
echo -e "Example: "
echo -e "\tfindremoteip *remote~ip [filter~by~process~name] [-v]\n"
echo -e "Usage: findremoteip 114.114.114.114"
echo -e "\tfindremoteip 114.114.114.114 ssh #仅查找该IP的ssh进程,其他进程忽略"
return 0
fi
local remoteIP="$1" && shift
local psName="" #用此参数查找进程,当远程IP有多个匹配进程时,用于过滤;
[ ! -z "$1" ] && [[ ! "${1,,}" == "/v" && ! "${1,,}" == "-v" ]] && psName="$1" && shift
local netstatInfo=$(cmd /c netstat -ano -p TCP|awk '{if(match($3,/^'"$remoteIP"':/)){print}}')
echo "$netstatInfo"
local pids=$(echo "$netstatInfo"|grep 'ESTABLISHED'|awk '{print $NF}'|dos2unix -q)
if [ -z "$pids" ]
then
echo "$remoteIP 地址没有找到相关进程..."
return 0
fi
for pid in $pids; #对多个远程IP关联进程依次处理!
do
if [ ! -z "$1" ] && [[ "${1,,}" == "/v" || "${1,,}" == "-v" ]]
then
cmd /c tasklist /v|iconv -s -f GBK -t UTF-8|grep $pid
else
cmd /c tasklist|grep $pid
fi
##查看此进程是否关联Windows服务,如果有,提示是否需要net stop停止服务
## Also you can use this powershell command:(Get-WmiObject Win32_Service -Filter "ProcessId='$PID'")
local serviceInfo=$(cmd /c tasklist /svc /NH /FI "PID EQ $pid"|iconv -s -f GBK -t UTF-8|grep -i "$psName")
[ -z "$serviceInfo" ] && continue
echo -e "关联服务信息查询:$serviceInfo"
local serviceName=$(echo "$serviceInfo"|dos2unix -q|sed -r '/^$/!{s/^.*'$pid' //;s/[\t| ]*$//g}'|tr -d '\n')
if [ ! "$serviceName" = "N/A" -a ! "$serviceName" = "暂缺" ];then
read -p ">> 进程发现关联服务,是否需要停止服务 “$serviceName”? yes/no(y/n),默认No: " stopService
if [[ "${stopService,,}" == "y" || "${stopService,,}" == "yes" ]];then
echo ">>> Stop Service ..."
gsudo net stop "$serviceName"
echo "To check remoteip $remoteIP again ..."
findremoteip $remoteIP
fi
else
echo "pid为 $pid 的进程未关联服务或服务不是Win32本地系统服务!"
echo "如:(“Cygwin sshd”是常驻服务,但不是本地服务,是用户登录服务)"
read -p ">> 是否需要终止进程 “PID:$pid”? yes/no(y/n),默认No: " killProcess
if [[ "${killProcess,,}" == "y" || "${killProcess,,}" == "yes" ]];then
echo ">>> Kill Process ..."
gsudo taskkill /F /PID "$pid"
fi
fi
done
}
使用帮助:
$ findremoteip
缺少远程IP!
`findremoteip` 查看连接到指定IP的相关进程:
Example:
findremoteip *remote~ip [filter~by~process~name] [-v]
Usage: findremoteip 114.114.114.114
findremoteip 114.114.114.114 ssh #仅查找该IP的ssh进程,其他进程忽略
使用效果:

附录:
另一辅助函数为findport
,功能:根据本地端口号查询占用端口的进程,并一键终止相关进程或服务;
可与本篇文章介绍的函数findremoteip
搭配使用,二者相互搭配,在敏捷开发与自动化运维场景中搭配食用效果更佳!
