   Inquiry Public network Ip:curl ifconfig.me
   Query Internet gateway: Tracepath cnblogs.com
   
   If you want to use ifconfig, you need yum install net-tools

   (Don't remember if yum install samba-client is required)
   (originally intended to pass files in this way, installing the sun JDK requires downloading the installation package, browsing the web, finding the installation package, downloading the installation package, or Windows convenient.)

   4. Uploading files to a remote host
      scp-p9922 hello.txt [Email protected]:~
