ROS2.9.27是不是有后门存在?是个疑问!!!
刚装好ROS后,用端口扫描器扫描21 FTP 服务器
22 22 号端口
23 telnet
80 www 网页浏览默然端口
443 www-ssl
1720 h323hostcall
2000 黑洞(木马)
3986 mapper-ws_ethd
8291 8291 号端口
下面四个端口好像有问题啊. h323这个我的也有...... :L 懒得答你的问题.....这些服务都可以关的!
楼上的人怎么说话呢?
你懂你就看不起我们这些不懂的啊!要知道你也是从不懂到懂的啊!!!!!
你懒得回答,怎么还打几个字呢?你干脆回也不要回了哇.
在这里装B. 呵呵！~！~
那些都是系统安装好默认开的状态，只要你不需要用不着你自己可以看着办关掉的~！！~ 8291是你的WINBOX登陆端口。。。 你可以再防火墙里面做
chaint=input in-interface=WAN action=drop完成这个规则后再扫描看看
这样做的缺陷是，你再路由器上PING，返回是timeout. 动不动就说后门，发贴前用用大脑。世界上没有100%安全的网络。
有防火墙你不会利用啊？
