Intrusion penetration techniques Xinetd port forwarding In some network environments, such as managing a LAN or deploying a dedicated LAN, it may still be necessary to access certain ports of the Intranet machine from outside. Generally, you must access the jump server to access the corresponding machine.In our example, we must achieve the dedicated LAN of the Management

Environment : VBox or Vitrualbox to connect the virtual machine, because the company intranet can not allocate IP (do not know if this is the reason), the virtual machine with the bridge can not reach the IP, virtual machine and host access to each other, so with Nat. Sorry : Nat is able to connect to the network, but also can access the host, and the host cannot access the virtual machine. However, also want to use SECURECRT in the host access to Linux (after all, Linux command line inconvenien

First introduce the environment:1. The host computer's operating system is scientific Linux, kernel version 2.6.18, hostname spvm02,ip address 135.100.101.102, and VMware Workstation 8 deployed.2. Guest (virtual machine) This side of the installed operating system is windows 7.3. Guest uses the VMNET8 network card to achieve Internet access through the NAT protocol.The feature that needs to be implemented is that other computers in the host network use Microsoft Remote Desktop to telnet to the g
